Every one of the Anker 's good ideas comes mired in caveats, and all the user tweaking in the world can't solve its fundamental design problems. The software deserves praise for making macros so easy to record and use, but otherwise, the feature set is pretty standard. Whereas, the range of 16 million colors empowers you to set your desired lighting color as profile indicator, that further embellishes the look of the device. Latest: smalltech 10 minutes ago. Question Uninitialized until download 2k16 for pc Post thread.
We do have a new lead though, the ledger has a safe deposit box under the regional manager's name. Guess what, dumb sucker wrote down his combination. Come with me to retrieve the box and you can keep any of the goodies in it that I can't use to press charges against these bastards. I hope you will find use from what you got out of the deposit box but I also have another job for you that might lead you to an opportunity to deal out justice for those who cannot. First things first, we can't just look like ruffians.
Find us a deputy badge, easy enough? I've lost so many friends´┐Ż please find me a patient list from the regional hospital or doctor's office. I just want to know who might still be out there. Go to location on map which is a hospital, and bring back the Patient record, hospitals are usually filled with zombies; be carful. The npc's value towards you will increase by , and you can ask the npc for an item from their inventory or teach you something, this also allows you to follow a mission tree marked in-wiki with.
I can't thank you enough for bringing me the patient records but I do have another request. You seem to know your way around´┐Ż could you take me to one of the FEMA camps? I know some were overrun but I don't want to believe all of them could have fallen. Go to the location highlighted in the map, the npc will follow you too, but be carful as the fema camps are filled with high tier zombies. The npc's value towards you will increase by , and you can ask the npc for an item from their inventory or teach you something, the follow up mission is Reach Farm House 3.
I really wish I could have done something to save my brother but he was one of the first to go. I'd like to start over, just rebuild at one of the farms in the countryside. Can you help me secure one? The npc's value towards you will increase by , and you can ask the npc for an item from their inventory or teach you something, this is the last mission in this mission tree.
As the world seems to abandon the reality that we once knew, it becomes plausible that the old superstitions that were cast aside may have had some truth to them.
Please go and find me a religious relic´┐Ż I doubt it will be of much use but I've got to hope in something. From what I understand, the creatures you encountered surrounding this relic were unlike anything I've heard of. It is laughable that I now consider the living dead to be part of our ordinary reality. Never-the-less, the church must have some explanation for these events.
I have located the residence of a local clergy man, could you go to this address and recover any items that may reveal what the church's stance is on these events?
You have no idea how interesting this diary is. I have two very promising leads´┐Ż First things first, the Catholic Church has been performing its own investigations into global cult phenomenon and it appears to have become very interested in a local cult as of recently.
Could you investigate a location for me? I'm not sure what was going on here but the priest seemed fairly worried about it. I have another task if you are feeling up to it. There is a prisoner that the priest made special mention of. I was wondering if you could see what may have happened to him or if he left anything in his cell. The priest admits the individual is rather unstable, to put it lightly, but the priest personally believed the man was some kind of repentant visionary.
I'm not in a position to cast out the account just yet´┐Ż it seems the man has prophesied events accurately before concerning the Church of Starry Wisdom. Go to the location highlighted in the map, a prison; and retrieve the book which is called visions solitude. The eater of the dead´┐Ż something was ripping zombies to shreds and only leaving a few scattered limbs´┐Ż. A few days ago another survivor and I were trying to avoid the cities by staying in the woods during the day and foraging for gear at night.
It worked well against the normal zed's but one night something caught onto our trail and chased us for ten minutes or so until we decided to split up and meet-up back here. My buddy never showed up and I don't have the means to kill whatever it was. Can you lend a hand? You're kitted out better than most´┐Ż would you be interested in making this world a little better for the rest of us? The towns have enough supplies for us survivors to start securing a foothold but we don't have anyone with the skills and equipment to thin the masses of undead.
I'll lend you a hand to the best of my ability but you really showed promise taking out that other beast. You, I, and a zombies laid to rest, what do you say? Apparently one of the other survivors picked up on an unusually dense horde of undead moving into the area. At the center of this throng there was a 'leader' of some sort. The short of it is, kill the son of a bitch. We don't know what it is capable of or why it is surrounded by other zombies but this thing reeks of trouble.
Do whatever it takes but we can't risk it getting away. We've got another problem to deal with but I don't think we can handle it on our own. So, I sent word out and found us a volunteer´┐Ż of sorts. He's vain as hell but has a little skill with firearms. He was supposed to collect whatever he had of value and is going to meet us at a cabin in the woods. Wasn't sure how long we were going to be so I told him to just camp there until we picked him up.
I got the brief so I know what I'm getting into. Let me be upfront, treat me like shit and I'm going to cover my own hide. However, you treat me well and give me something to believe in, even if it's just a shiny bit of metal, and I'll do you right. Without a strong band a man doesn't stand a chance in this world. You ready to take charge boss? This world could use a Sheriff just about now. Investigate a nearby field and return with Dr. Prado and the robot prototype she was testing.
If the robot remains operational, avoid direct confrontation and use EMP grenades to disable it. One of our scientists recently left the lab to perform a field test on a prototype robot, but failed to return, and has not been heard of since. Investigate the test and return with her and the prototype. Failing that, return with the data recorder that was attached to our prototype. Find the corpse of a Hub 01's AI researcher and use the mind splicer kit to recover the memories stored inside their memory implant.
When the portal storms started, the Government issued an evacuation order for critical XEDRA personnel and sent convoys to retrieve them, with our head of AI research among the recalled.
We recently discovered that he died when the convoy transferring him was ambushed in the initial chaos, but his corpse and memory bionic might remain intact enough for us to extract valuable knowledge. We want you to travel to the location, make a copy of his Bionic Memory Unit, and return it to us.
Go to location highlighted on the map, you will find a military cars wreck, you have to find the person's body and use the mind splicer kit on them and return the data.
You will get four RobofacCoins and a new mercenary npc will spawn near the entrance also a free merchants camp will spawn in the parking lot. Reach the collapsed tower basement, and search the ruins for a photonic circuitry template. The intercom warned you about heavy enemy presence, and of the existence of a hazardous environment. Our facility once sourced advanced photonic circuitry from a nearby robotics manufacturer.
Their building suffered major damage during the portal storms, and collapsed almost entirely. However, preliminary scouting reveals that the basement prototyping lab likely remains intact. Go to location highlighted on the map, you will find a collapsed tower, it's a dangerous place so be careful, go to the lower floor, which filled with radiations and bring the photonics template. You can intercept the robot indicated by Hub 01, or find an inactive robot somewhere else.
Our scout drones have already revealed the location of a stray robot that fits our purposes, and we simply ask you to intercept it, disable it, and retrieve it for us. We will equip you with a prototype gun fit for this purpose, if you accept. Go to location highlighted on the map, you will find a robot there, using the gun given to you by the intercom you have to shoot the robot, If you manged to hit the robot you will disable it, return the robot to the hub. This clown was into some of the different things, not the vanilla, you understand me?
I think you will find my valuables in a toy shop not so so far. Go to location highlighted on the map, which is a Yes, please. If you can ask around for someone who can help, I can gather the tools they will need and some payment for them. Go ask the center's npcs if they want to join you in cleaning the back room you just cleaned the zed from.
We now have a space to work in, and I have wood and nails to spare. All I need is a saw. I would love tablesaw and mitre saw, but I can work with a hand held circular saw for now. I have looked, and what we have is garbage. Can you bring me a good one? If you can find it, it would mean so much to me. I will give you directions to the shelter where he left it. The user is authenticated using enterprise credentials. You can use the realm utility and its various sub-commands to troubleshoot the enterprise login configuration.
To see whether the machine is configured for enterprise logins, run the following command:. Network administrators can configure and pre-join workstations to the relevant domains using the kickstart realm join command, or running realm join in an automated fashion from a script.
You can enable workstations to authenticate using smart cards. In order to do so, you must configure GDM to allow prompting for smart cards and configure operating system to log in using a smart card.
You can use two ways to configure the GDM to allow prompting for smart card authentication with GUI or using the command line. You can enable smart card authentication using dconf editor GUI. The dconf Editor application helps to update the configuration-related values on a dconf database. You can use the dconf command-line utility to enable the GDM login screen to recognize smart card authentication.
For smart card authentication you can use the system-config-authentication tool to configure the system to allow you to use smart cards. Thus, you can avail GDM as a valid authentication method for the graphical environment. The tool is provided by the authconfig-gtk package. You can use the system-config-authentication tool to enable fingerprint authentication to allow users to login using their enrolled fingerprints.
You can disable the print dialog from being shown to users. This can be useful if you are giving temporary access to a user or you do not want the user to print to network printers. The feature only works in applications which support it. The changes do not have effect on applications which do not support this feature.
To prevent applications from printing, lock down the org. Having followed these steps, applications supporting this lockdown key, such as Evolution , Evince , or Gedit , will disable printing. You can disable the Save and Save As dialogs. This can be useful if you are giving temporary access to a user or you do not want the user to save files to the computer.
The changes will have no effect on applications which do not support this feature. To prevent applications from file saving, lock down the org. This file contains a set of actions and default values, which can be overridden by system administrator. Users can evade the logout lockdown by switching to a different user.
To prevent such scenario, lock down user switching as well. Single-application mode is a modified GNOME session that reconfigures the Mutter window manager into an interactive kiosk. This session locks down certain behavior to make the standard desktop more restrictive.
The user can interact only with a single application selected by the administrator. You can set up single-application mode in a number of fields, from communication to entertainment or education, and use it as a self-serve machine, an event manager, a registration point, and so on. The single-application mode configuration is available from the gnome-session-kiosk-session package.
This procedure installs and enables single-application mode, which restricts the GNOME session to a single application. Install the gnome-session-kiosk-session package:. For example, to launch the Firefox browser in single-application mode, enter the following content:. The while true loop ensures that the application restarts if it terminates for any reason.
If you created the file or its containing directories as a different user than the single-application user, such as root , ensure that the file has the correct permissions:. Org display servers for both local and remote logins. When you make changes to the system configuration such as setting up the login screen banner message, login screen logo, or login screen background, restart GDM for your changes to take effect. Create a. Enter the following content in the file:.
Optionally, configure the application to start only when a selected GSettings key is enabled. As an administrator, you can enable automatic login from the Users panel in GNOME Settings , or you can set up automatic login manually in the GDM custom configuration file, as follows. Run the following procedure to set up automatic login for a user john. Replace john with the user that you want to be automatically logged in.
User sessions that have been idle for a specific period of time can be ended automatically. You can set different behavior based on whether the machine is running from a battery or from mains power by setting the corresponding GSettings key, then locking it. The number of seconds that the computer needs to be inactive before it goes to sleep if it is running from AC power. What should happen when the timeout has passed if the computer is running from AC power.
The number of seconds that the computer needs to be inactive before it goes to sleep if it is running from power. What should happen when the timeout has passed if the computer is running from battery power.
You can configure a default desktop session that is preselected for all users that have not logged in yet. If a user logs in using a different session than the default, their selection persists to their next login. Optional : To configure an exception to the default session for a certain user, follow these steps:. Replace 30 with the integer value you want to use. To set idle time after which the screen is blanked and the default screensaver is displayed:. Replace with the integer value you want to use.
You must include the uint32 along with the integer value as shown. To enable the screensaver and make the screen lock automatically when the user is idle, follow this procedure:. You must include the uint32 along with the integer key values as shown. The recorder allows users to record desktop or application activity during their session and distribute the recordings as high-resolution video files in the webm format. When the recorder is capturing the screen activity, it displays a red circle in the top-right corner of the screen.
The built-in recorder always captures the entire screen, including all monitors in multi-monitor setups. This procedure sets a default screen rotation for all users on a system and is suitable for mass deployment of homogenized display configuration. An example portrait orientation:. As a system administrator, you can configure the desktop environment to support users with a visual impairment.
Accessibility for users with a visual impairment is ensured by the Orca screen reader on the Red Hat Enterprise Linux 8 desktop. Orca is included in the default RHEL installation. Orca reads information from the screen and communicates it to you using the following components:.
The Braille display is a device that uses the brltty service to provide tactile output for visually impaired users. To enable the Braille display, enable the brltty service to start automatically on boot.
By default, brltty is disabled. Ensure that brltty and speech synthesis for brltty are installed:. To set the users who are authorized to use a Braille display device, you can choose one of the following methods, which have an equal effect:. To specify one or more individual users, list the users on the following line:. Decide whether you want to use the autodetection for finding the appropriate driver for your Braille display device. Autodetection tries all drivers.
Therefore, it might take a long time or even fail. For this reason, setting up a particular driver is recommended. If you do not want to use the autodetection, specify the identification code of the required driver in the braille-driver directive. You can also set multiple drivers, separated by commas, and autodetection is then performed among them.
Table Braille display device types and the corresponding syntax. You can also set multiple devices, separated by commas, and each of them will be probed in turn. If the device is connected by a serial-to-USB adapter, setting braille-device to usb: does not work.
In this case, identify the virtual serial device that the kernel has created for the adapter. The virtual serial device can look like this:. You can find the actual device name in the kernel messages on the device plug with the following command:.
The braille-parameters directive passes non-generic parameters through to the braille driver. If you want to use the autoselection, leave text-table specified to auto, which is the default option. This ensures that local-based autoselection with fallback to en-nabcc is performed. For example, to use the contraction table for American English, grade To activate the Orca screen reader, enable the Always Show Universal Access Menu option as described in the following procedure.
Check that the Universal Access Menu icon is displayed on the top bar even when all options from this menu are switched off.
As a result, the Universal Access Menu icon is displayed on the top bar. If you activate Orca by pressing the keyboard shortcut, the icon disappears in case that the user disables all of the provided options from the Universal Access Menu. The missing icon might cause difficulties to users with a visual impairment.
You can prevent the inaccessibility of the icon by switching on the Always Show Universal Access Menu option as described in the above procedure. When the Always Show Universal Access Menu option is enabled, the icon is displayed on the top bar even when all options from this menu are disabled. Both these tools, as well as the libinput stack, use the libwacom tablet client library, which stores the data about Wacom tablets.
If you want to add support for a new tablet into the libwacom library, you must ensure that a definition file for this new tablet exists. The libwacom tablet client library needs a definition file for the tablet that you want to add. List all local devices recognized by libwacom :.
If your device is not listed, the device is missing from the libwacom database. Org display server, in the X11 session on the xinput list. To use the screen mapping correctly, support for your tablet must be included in the libwacom database and in the udev rules file. A common indicator that a device is not supported by libwacom is that it works normally in a GNOME session, but the device is not correctly mapped to the screen.
You can create a new tablet definition file. To add support for a new tablet into the libwacom tablet information client library, follow this procedure. For more information on ensuring that the definition file exists, see Section Add and install the definition file with the.
Once installed, the tablet is part of the libwacom database. The tablet is then available through libwacom-list-local-devices. The configuration schema for the tablet is org. For the consumer ranges with no support for tool-id , a generic identifier is used instead. The configuration schema for the stylus is org. The configuration schema for the eraser is org. To get the full list of tablet configuration paths used on a particular machine, use the gsd-list-wacom tool, which is provided by the gnome-settings-daemon package.
Make sure that the gnome-settings-daemon package is installed on your system. To get the full list of tablet configuration paths used on your machine, run the following command:. Using machine-id , device-id , and tool-id in configuration paths allows for shared home directories with independent tablet configuration per machine.
However, when sharing home directories between Machines, the Wacom settings apply only to one machine. You can install certain applications using the Flatpak package manager. The following sections describe how to search for, install, launch, and update Flatpak applications on the command line and in the graphical interface.
Red Hat provides Flatpak applications only as a Technology Preview feature. Technology Preview features are not supported with Red Hat production service level agreements SLAs and might not be functionally complete.
Red Hat does not recommend using them in production. These features provide early access to upcoming product features, enabling customers to test functionality and provide feedback during the development process. Flatpak provides a sandbox environment for application building, deployment, distribution, and installation. Applications that you launch using Flatpak have minimum access to the host system, which protects the system installation against third-party applications.
Flatpak provides application stability regardless of the versions of libraries installed on the host system. Flatpak applications are distributed from repositories called remotes.
Additionally, third-party remotes are available as well. Red Hat does not support applications from third-party remotes. For large-scale deployments where the users do not have Customer Portal accounts, Red Hat recommends using registry service accounts.
For details, see Registry Service Accounts. Provide the credentials to your Red Hat Customer Portal account or your registry service account tokens.
Optional: Save your credentials permanently. Use one of the following options:. For best practices, Red Hat recommends that you log into the Red Hat Container Catalog using registry account tokens when installing credentials system-wide. This procedure searches for an application in the enabled Flatpak remotes on the command line. The search uses the application name and description.
For example, to search for the LibreOffice application, use:. This procedure installs a selected application from the enabled Flatpak remotes on the command line. Replace application-id with the ID of the application. This procedure launches an installed Flatpak application from the command line. This procedure updates one or more installed Flatpak applications to the most recent version in the corresponding Flatpak remote.
This procedure searches for Flatpak applications using the Software application. If the application is listed several times, select the version where the Source field in the Details section reports flatpaks.
This procedure updates one or more installed Flatpak applications using the Software application. Enable Automatic Updates. Jump To Close Expand all Collapse all.
