So. I have big problems with nouveau driver or implementation of nouveau driver (by Debian). I emailed debian-x@lists.debian.org team but have heard nothing back.

Straight out the box, some graphical features do not work / are buggy / might hang the system - depending on which DE you use and what eye-candy it has enabled by default. XFCE/LXQT appear unaffected yet KDE Plasma is producing many graphical anomalies/artefacts and gdm did hang.

In every DE and version of Debian since Jessie, 360 degree videos (in browser) just display noise. This behaviour changes when using the proprietary 304xx nvidia driver, but the videos still do not function properly - though you do now see the correct video patchwork the 360deg video is generated from.

In trying to exercise this problem, I discovered glxgears works fine, yet glmark2 will always crash with a segmentation fault between tests 2 and 3. With nvidia driver installed, glmark2 fails to start at all and gives this :-


libGL error: No matching fbConfigs or visuals found
libGL error: failed to load driver: swrast
** GLX does not support GLX_EXT_swap_control or GLX_MESA_swap_control!
X Error of failed request: BadValue (integer parameter out of range for operation)
Major opcode of failed request: 155 (GLX)
Minor opcode of failed request: 24 (X_GLXCreateNewContext)
Value in failed request: 0x0
Serial number of failed request: 39
Current serial number in output stream: 40


Might be worth noting that after installation of the proprietary driver apt was reporting:-

ldconfig: /usr/lib/x86_64-linux-gnu/libGL.so.1 is not a symbolic link


I had a brief fling with Piglit. It crashed however. And when trying to use valgrind it looked like it was going to take over a day.

Attached are a Xorg.0.log (should module "nv" be being loaded?) and a dmesg output - both from a Debian Stretch install. I have concurrent installs of Buster and Wheezy I can fire up if it will help.

The issue might not exist (or is different) in Wheezy. The 360 degree videos after a fresh install look like the other releases after the proprietary driver has been installed, ie I can see the patchwork video rather than just noise.
