Trying to check older versions I discovered the bug is only triggered by
the following sequence:
- use 'nvidia' (e.g. boot to graphical login)
- update-alternatives --set glx /lib/bin/mesa-diverted (and remove any
'nvidia' relevant bits from xorg.conf)
- reboot to use 'nouveau'
- dpkg -i libgl1-nvidia-glx
I can reproduce this with all 340.x. Going further back would require
downgrading Xorg, so I didn't test. If you need any specific info don't
hesitate to ask.
Hope this helps,
