Low Resolution after suspend

Hi!

I'm writing as I have no idea what is going wrong with my desktop. I'd like to use a suspend feature from time to time. But after resume - the resolution is extremely low (640x480). Moreover the second display does not work at all.

This issue probably is not related to environment (KDE), as other virtual terminals are affected by this issue too. I can switch to pure terminal and I cannot read anything as all fonts are blurred.

The issue does not reproduce if I resume from suspend immediately (after several seconds).

I suspect something related to graphic card. Everything works fine with integrated Intel, but now I'm relying on GTX 1080 (however suspend works fine on Windows) and proprietary nvidia driver.

What kind of information could be useful for diagnostic? There are no errors in dmesg journal.

Re: Low Resolution after suspend

I've decided to attach an Xorg.0.log, as it looks at least strange for me:

There is a lot of display disconnect events.

This is the same Xorg.0.log file, after reproduction of resume issue:

This is probably the key part of it:
