Proprietary (NVIDIA/AMD) drivers are known to be sometimes highly problematic, or completely unsupported.
AMD driver support is prebaked in the Qubes kernel (4.14) but only RADEON HD 4000-9000 give or take, NOT most of the latest cards.
NOT until AMDGPU support in the 4.5+ kernel, which isn't released yet for Qubes.
Built in Intel Graphics, Radeon graphics (between that 4000-9000 range), and perhaps some prebaked NVIDIA cards i don't know about. Those are your best bet for Great Qubes support.
If you do happen to get proprietary drivers working on your Qubes system (Via installing them). Please take the time to go to the
[Hardware Compatibility List (HCL)](https://www.qubes-os.org/doc/hcl/#generating-and-submitting-new-reports )
Add your computer, graphics card, and installation steps you did to get everything working.
There are rpm packages with all necessary software on rpmfusion. The only package you have to compile is the kernel module (but there is a ready built src.rpm package).
You will need any Fedora 18 system to download and build packages. You can use Qubes AppVM for it, but it isn't necessary. To download packages from rpmfusion - add this repository to your yum configuration (instructions are on their website). Then download packages using yumdownloader:
In above command replace `uname -r` with kernel version from your Qubes dom0. If everything went right, you have now complete packages with nvidia drivers for Qubes system. Transfer them to dom0 (e.g. using a USB stick) and install (using standard "yum install /path/to/file").
This process is quite complicated: First - download the source from nvidia.com site. Here "NVIDIA-Linux-x86\_64-260.19.44.run" is used. Copy it to dom0. Every next step is done in dom0.
**WARNING**: Nvidia doesn't sign their files. To make it worse, you are forced to download them over a plaintext connection. This means there are virtually dozens of possibilities for somebody to modify this file and provide you with a malicious/backdoored file. You should realize that installing untrusted files into your Dom0 is a bad idea. Perhaps it might be a better idea to just get a new laptop with integrated Intel GPU? You have been warned.
- nvidia kernel module sources (left from previous step)
- kernel-devel package installed
- gcc, make, etc
This installation must be done manually, because nvidia-installer refused to install it on Xen kernel. Firstly ensure that kernel-devel package installed all needed files. This should consists of:
If all the files are not there correct the errors manually. To build kernel module, enter *NVIDIA-Linux-x86\_64-260.19.44/kernel* directory and execute:
Specifically, the notes below are aimed to help when the GRUB menu shows up fine, the installation environment starts loading, and then the display(s) go into standby mode. This is, typically, related to some sort of an issue with the kernel's KMS/video card modules.
## Initial setup.
*Note*: The steps below do *not* produce a fully-functional Qubes OS install. Rather, only a dom0 instance is functional, and there is no networking there. However, they can be used to gather data in order to troubleshoot video card issues and/or possible other basic kernel module issues.
1. Append `nomodeset ip=dhcp inst.nokill inst.vnc` to the kernel command line. Remove `rhgb` and `quiet` to see the kernel messages scroll by, which may help in further diagnostics.
* If DHCP is not available on the installation network, the syntax becomes a bit more involved. The full list of variants is documented in the [Dracut Command-line parameters] (http://man7.org/linux/man-pages/man7/dracut.cmdline.7.html)
* Since this won't be a usable install, skipping LUKS encryption is an option which will simplify this troubelshooting process.
* Do *not* reboot at the end of the installation.
5. Once the installation completes, use the local VGA console switch to TTY2 via ALT-F2
* Switch to the chroot of the newly-installed system via `chroot /mnt/sysinstall`
* Set the root password (this will also enable the root account login)
* Double-check that `/boot/grub2/grub.cfg` contains a `nomodeset` kernel parameter.
* Exit out of the chroot environment (`exit` or CTRL-D)
6. Reboot
*Note* If the kernel parameters do *not* include `quiet` and `rhgb`, the kernel messages can easily obscure the LUKS passphrase prompt. Additionally, each character entered will cause the LUKS passphrase prompt to repeat onto next line. Both of these are cosmetic. The trade-off between kernel messages and the easy-to-spot LUKS passphrase prompt is left as excercise to the user.
## Gather initial `dmesg` output
If all is well, the newly-installed Qubes OS instance should allow for user root to log in.
Run `dmesg > dmesg.nomodeset.out` to gather an initial dmesg output.
## Gather the 'video no worky' `dmesg` output
1. Reboot and interrupt the Grub2's process, modifying the kernel parameters to no longer contain `nomodeset`.
* If the LUKS passphrase was set, blindly enter it.
2. Wait for the system to finish booting (about 5 minutes, typically).
3. Blindly switch to a TTY via CTRL-ALT-F2.
4. Blindly log in as user root
5. Blindly run `dmesg > dmesg.out`
6. Blindly run `reboot` (this will also serve to confirm that logging in as root, and running commands blindly is possible rather than, say, the kernel having hung or some such).
* Should this step fail, perhaps by the time step #3 was underaken, the OS hasn't finished coming up yet. Please retry, possibly with a different TTY (say, 3 or 4 - so CTRL-ALT-F3?)
## Exfiltrate the dmesg outputs
Allow the system to boot normally, log in as user root, and sneakernet the files off the system for analysis, review, bug logging, et cetera.
