Description Olivier Fourdan 2021-10-20 09:02:49 UTC

This bug was initially created as a copy of Bug #2015839

I am copying this bug because: 

The same applies to Red Hat Enterprise Linux 8

Description of problem:

With the release of NVIDIA proprietary driver series 495, the NVIDIA driver now supports GBM buffers.

If a customer install that version, the current version of Xwayland will fail to map any window without the required fixes for Xwayland:

https://gitlab.freedesktop.org/xorg/xserver/-/merge_requests/766

Version-Release number of selected component (if applicable):

xorg-x11-server-Xwayland-21.1

How reproducible:

Always

Steps to Reproduce:
1. Install the NVIDIA proprietary driver series 495

Actual results:

No X11 window can show up on screen.

Expected results:

X11 windows show up on screen.

Additional info:

This will allow Xwayland to be future proof, compatible with the newer NVIDIA driver even though installing the NVIDIA proprietary driver series 495 has additional dependencies (Mesa 21.2.x, egl-wayland-1.1.9, which requires libglvnd 1.3.4 at least, etc.).

Comment 1 Peter Kopec 2021-12-08 14:45:43 UTC

With xorg-x11-server-Xwayland-21.1.3-1.el8 and nvidia driver 495.44 wayland works using EGLStream backend. Waiting to best also GBM buffer support once it is ready before setting verified.

Based on #c1
