 Posted: Fri Feb 16, 2024 8:36 pm Post subject: nvidia xorg without mesa |
 |
|
There are multiple ways of using a nvidia gpu on linux.
There are the nouveau drivers and the proprietary drivers.
This guide is for users of the proprietary drivers.
I have tried using the open source drivers too, but I've had problems with hw accel, which is a deal-breaker for me.
The proprietary nvidia drivers already have their own implementations of everything in mesa.
You can see for yourself by running:
| Code: |
$ equery f nvidia-drivers | grep lib | grep so
|
If you don't use steam and such, the process of using xorg without mesa is quite simple:
Enable USE="minimal" on xorg-server.
Disable USE="dri" on mpv, if you use it.
Rebuild and emerge -cav.
And that should be it.
I use steam, which requires xorg built with glx, and for which the process is a bit more involved.
Enable USE="minimal" on xorg-server.
Disable USE="dri" on mpv, if you use it.
Create the text file /etc/portage/env/x11-base/xorg-server, if it doesn't exist.
Add:
| Code: |
MYMESONARGS="-Dglx=true"
|
to the file /etc/portage/env/x11-base/xorg-server.
After doing this, you will have to install this header:
https://github.com/stefan11111/dri_interface.h
I have an ebuild for it here, but you can install it any other way you like:
https://github.com/stefan11111/stefan_overlay/blob/main/x11-base/xorg-dri-interface/xorg-dri-interface-1.0.ebuild
After doing this, you will have to put this patch in /etc/portage/patches/x11-base/xorg-server/<whatever you want>.patch :

Rebuild xorg-server and mpv(if you use it).
Steam depends on virtual/opengl-7.0-r2.
That virtual depends on mesa, but is not actually needed by steam.
To get rid of it, create the text file /etc/portage/profile/package.provided if it doesn't exist, and add:
| Code: |
virtual/opengl-7.0-r2
|
To it.
After doing this, emerge -cav should prompt you to uninstall mesa.

Not having to build mesa.
