PPA description

PLEASE READ: don't email me to report bugs, unless you are sure it's a packaging bug. Not only is email not a good tool for tracking bugs, it also excludes anybody else from tracking or working on the issue. Please read the section "Debugging and reporting problems" below.

Also, please don't ask me to include non-free drivers, I won't do it.

Patches and suggestions are welcomed.

=============

Supported architectures: amd64, arm64, i386

Supported Ubuntu versions:

- 18.04 (bionic) <- obsolete, and you need to install newer kernel with:

sudo apt install --install- recommends linux-generic- hwe-18. 04

- 20.04 (focal) <- supported

- 20.10 (groovy) <- supported

For forum support see: http:// goo.gl/ qoUpWK

=== Introduction ===

This PPA provides updated free graphics drivers packages for radeon, intel and nvidia hardware. Updates packages provide:

* all driver packages are automagically built twice a day, when there are upstream changes

* Vulkan 1.2+ on recent intel and radeon GPU

* OpenGL 4.6+ support and new OpenGL extensions: http:// mesamatrix. net

* gallium-nine support. Read the specific section below

* VDPAU and VAAPI Gallium3D accelerated video drivers (see below)

* packages built against latest stable LLVM

* Intel iris driver enabled by default

* mesa packages built with gcc LTO for smaller binary size (~10-15%) and improved performance

As an added bonus I may include some updated open source games (backported from Debian or newer Ubuntu).

=== Basic usage ===

See "Adding this PPA to your system" later on, or just do:

sudo add-apt-repository ppa:oibaf/ graphics- drivers

and update your Ubuntu with the package here.

=== Using gallium-nine ===

Gallium-nine lets you run DirectX 9 games in a faster way, avoiding the inefficient translation of D3D9 calls to OpenGL. For more info see https:/ /wiki.ixit. cz/d3d9

You need:

* enable this PPA (see previous paragraph)

* then follow the instructions to install wine from this PPA: https:/ /launchpad. net/~commendsar nex/+archive/ ubuntu/ winedri3

=== Using alternative drivers - Here be dragons ===

* zink - OpenGL emulated on a Vulkan driver:

Set MESA_LOADER_ DRIVER_ OVERRIDE= zink

* Old Intel i965 OpenGL driver (iris is the default):

Set MESA_LOADER_ DRIVER_ OVERRIDE= i965

* llvmpipe OpenGL software render:

Set MESA_LOADER_ DRIVER_ OVERRIDE= llvmpipe

* Other options here: https:/ /www.mesa3d. org/envvars. html

=== Using accelerated video ===

Supported VDPAU drivers: r300, r600, radeonsi, nouveau

Supported VAAPI drivers: r600, radeonsi

* First you need to install mesa-vdpau-drivers package:

sudo apt-get install mesa-vdpau-drivers

* Then to test the VDPAU driver with mpv use:

$ mpv --hwdec=vdpau yourvideofile

=== Upgrading to a newer Ubuntu ===

It is *strongly* suggested to remove all packages from this PPA before updating to a newer Ubuntu release. See the section "Revert to original drivers" later on.

Then, after the upgrade, you can add again this PPA.

=== Debugging and reporting problems ===

If you have some problem with the drivers try running the application from the command line and see if there are graphics related warnings. Also type dmesg to see if there are other related information here.

If you get crashes install the relevant -dbg pacakges (libgl1- mesa-dri- dbg or libgl1- mesa-dri- experimental- dbg for 3D drivers and xserver- xorg-video- intel-dbg , xserver- xorg-video- nouveau- dbg or xserver- xorg-video- radeon- dbg for X drivers) and reproduce the crash with gdb. Example:

$ gdb glxgears

[...make your application crash and then get a backtrace with:]

(gdb) bt

If X.org crashes look at /var/log/Xorg.0.log (or /var/log/ Xorg.0. log.old when a new X session is started after the crash).

With the gathered information try searching at https:/ /bugs.freedeskt op.org/ query.cgi (also try with google) if someone already reported a similar bug. If not you may want to report a new bug:

for 3D drivers bugs: https:/ /www.mesa3d. org/bugs. html

for X / 2D driver bugs: https:/ /bugs.freedeskt op.org/ enter_bug. cgi?product= xorg

=== Revert to original drivers ===

To revert to standard Ubuntu drivers type the following in a prompt shell:

$ sudo apt-get install ppa-purge

$ sudo ppa-purge ppa:oibaf/ graphics- drivers

=== Donations ===

Some people asked me if I can accept donations to support this work. I don't, but if you have some spare money I would be happy if you could do a donation to a charity of your choice (for the poors, animals, whatever else you may think it might need it). Then feel free to send me a note about it!
