Comment # 2 on bug 92961 from Pierre Moreau

I would start by blacklisting the NVIDIA driver, to prevent it from loading
while Nouveau is being used as it may results in conflicts. (Just write a file
named `whichever_name_you_want.conf` in `/etc/modprobe.d/`, and containing
`blacklist nvidia`.)

Regarding the second attachment, could you rather please attach Xorg0.log as
found in `~/.local/share/xorg/`, or `~/.local/xorg/` or `/var/log/`? (From a
run that froze, and please attach the corresponding dmesg, so that both the
dmesg and the Xorg.log are from the same run.)

Have you noticed anything that may cause the freeze, like starting a browser,
running some OpenGL application, or even some fancy compositor animation?
