Problem: When running a machine with an Nvidia GPU, you notice graphical issues such as being stuck at a low resolution, failure to launch UI, poor game performance or slow rendering.
Solution: Install closed source Nvidia drivers per the following instructions: Note: Do not install drivers from Nvidia's website
Depending on which Nvidia card you have, follow the instructions in A, B or C.
A) If you have a 10 series card or newer, run the following command:
sudo apt install nvidia-driver-latest
B) If your card is older than the 10 series, check Nvidia's Website to see which driver corresponds to your graphics card. If it is the latest Nvidia driver (545 at the time of writing), run the following command
sudo apt install nvidia-driver-latest
Note: You can see what the latest Nvidia drivers packages are available in apt using the following command and looking for the highest numbered driver release
apt search nvidia-driver
C) if you card is older than the 10 series and the driver listed on Nvidia's Website is older than the latest driver, do the following:
Install, through apt, the package that corresponds to your driver. If the latest available driver is 470, run
sudo apt install nvidia-driver-470
You can use the apt search command example in section B to see which Nvidia driver packages are available.
Next, install the disable-nouveau package
sudo apt install disable-nouveau
Lastly, whether you followed the instructions in A, B or C, reboot your computer.
Problem: After installing a specific Nvidia driver version and rebooting, the system is still running Nouveau
Solution: We need to blacklist Nouveau by creating installing the following package
sudo apt install disable-nouveau
Problem: After installing the Nvidia driver, there is still no graphical output.
Solution: If this is a fresh Drauger OS install, reinstall the OS. Then, make sure your system is up-to-date before installing the Nvidia drivers.
Otherwise, contact support so we can walk you through more complex recovery procedures.
Problem: Upon trying to launch Steam, you received the error
Fatal error: Failed to load steamui.so
Solution: Try running the following command
sudo apt install --reinstall libva-x11-2:i386
Problem: After installation of Drauger OS, the computer boots only to an iniramfs and/or busybox prompt.
Solution: Reinstall Drauger OS, but ensure the "install updates during installation" and "install restricted extras" options are disabled.
Problem: When attempting to install a Flatpak or update the system, the computer displays an error messages that ends with "Invalid NULL Filename:
Solution: Run the following command
sudo flatpak repair
sudo apt upgrade" returns "The following upgrades have been deferred due to phasing"Problem: When attempting to run an upgrade, not all updates where applied and apt said some packages upgrades have been deferred due to phasing.
Solution: This is not a problem. When apt chooses to defer some update(s), it is doing so because a change in one or more packages may adversely affect some users. To test this, the developers of the package have opted to roll the upgrade out in stages. This message simply states you will get the update at a later stage. While it is not advised, you can bypass this with the following command:
sudo apt install <deferred_packages>
where <deferred_packages> is the list of packages the upgrade has been defered on.
