Hi Andreas,Thanks very much for the quick reply. I've given this a try as requested: nvidia-tesla-450-driver and dependencies installed, then ran "update-glx --config nvidia" and selected /usr/lib/nvidia/tesla-450 and rebooted after it had recreated the initrd.
On reboot, I checked the X server log to ensure it had selected the correct version, and "450.102.04" was reported, so that looked good. At that point, I tried switching away to a new display then switching back, removing and re-inserting cables, and forcing a DPMS off state using xset, and each time the display came back without any problems, so it looks like the CVE fix isn't the cause of the problems.
Let me know if I can try anything else, and thanks again for your efforts. All the best, -Dave. On 26/01/2021 19:26, Andreas Beckmann wrote:
Hi David, could you try nvidia-tesla-450-driver 450.102.04-1 from sid? It is installable along the regular driver and you can switch between the different drivers with update-glx (and then reboot to load the other kernel module and libraries). This is just to check whether the 450 series got "broken" too with the latest version (which includes a CVE fix). Thanks Andreas PS: If it is still working fine, we might keep the tesla-450 driver in bullseye along tesla-460.
