Hello, I’m experiencing a problem, that does not always happen but is very common. When I boot my PC, there’s is a big chance that after logging in it goes to a black screen before really logging in and loading system. After finally getting to the desktop, both monitors go black and I’m again asked to log in, after logging in for the second time, both monitors stop receiving any signal, like if they weren’t connected to the at the PC.
I really don’t have a clue on what’s going on or why. Please help cause it’s getting really annoying.
Edit: seems like is a situation where that happens or the entire PC is bound to freeze out of nowhere, no matter what I’m doing or how much the cpu is being used, not even my keyboard responds
There is likely useful information in the system journal and user journal.
Have a look for errors leading up to the time when you get the black screen.
Please post the output of inxi -Fzxx so we know what hardware and software you have on your system.
Hi, thank you for your reply, sorry to take so long on mine. Was doing some testings to find some clues. I think that it might be related to the kernel version and my drawing tablet, a Huion Kamvas Pro 20(2019), that, when I’m not drawing or in blender, I use as a second monitor, usually I connect it through hdmi and the main monitor through dp. I also dual boot with Windows 10 and this set up works without any problems.
Whenever I have the tablet connected and boot on the most recent kernel, the one you can see on the output of the inxi I added below, the issue is present, if I disconnect the device, the issue is gone, although so far there are random times where the screen goes black for like less than a minute and comes back, no freezing. And nothing of this happens if I boot on the previous kernel I have available, I can have the tablet connected and no issues arise, except that the game I’m looking to play becomes unplayable.
And regarding the Journal, after a session with the issue, I checked it and found the following highlights:
/usr/bin/nvidia-powerd[926]: Found unsupported configuration. Exiting...

I need to add that I don’t see any authentication error or wrong password/username message when logging in. Let me now if it would be better to copy the complete log from start to finish.
