Since a few days, when I turn off my screen and turn it on again few minutes later, there is no display. I'm using the Nvidia proprietary drivers, not sure if it's relevant. I checked `dmesg` and there was nothing related to that.

It doesn't happen on regular kernel.

I also tried with older versions like 5.10-liquorix or 5.8-liquorix, still crashes. So it might be a recent update on the Ubuntu side.

System informations:
Ubuntu 20.04 - Liquorix 5.12 - intel celeron j4115 - nvidia GTX 1050Ti

Note that 'the regular kernel' has no meaning, you have to say what it is.

Sure, we can look up what ubuntu 20-4 shipped with, but why?

There's no such thing as a regular kernel, there are specific kernels in the distro and in liquorix.

Odds are good that something is glitching in the nvdiia driver, it worked in kernel 5.4, doesn't seem to work in 5.10 or newer.

Since liquorix can't fix or alter the nvidia non free driver, your best bet is probably to stop turning your monitor off manually, and switch to using power saving to turn it off, then see if it starts working.

Otherwise, you have to post a bug report on nvidia forums, not here.
