I don't think you can do anything, it's on Nvidia. Or, maybe you can provide the last 45x driver within the siduction repository?
As far I can see it's a problem with the monitor, from Dell and Benq, maybe others.
If someone already have this problem, a workaround could be:
- use the nouveau driver
- if the nvidia card is supported by the tesla driver, use this one (like me, ask nvidia-detect)
:~$ nvidia-detect
Detected NVIDIA GPUs:
09:00.0 VGA compatible controller [0300]: NVIDIA Corporation TU106 [GeForce RTX 2060 SUPER] [10de:1f06] (rev a1)
Checking card: NVIDIA Corporation TU106 [GeForce RTX 2060 SUPER] (rev a1)
Your card is supported by the default drivers.
Your card is also supported by the Tesla 460 drivers series.
Your card is also supported by the Tesla 450 drivers series.
It is recommended to install the
nvidia-driver
package.
To access the system you have to start with grub option "single" and than remove all the nvidia stuff.
apt purge *nvidia*
and reboot.
For nouveau, I think, you need to install at least
apt install xserver-xorg-video-nouveau
And for Tesla
apt install nvidia-tesla-460-driver
Hope this helps
