Bug Description

ubuntu 20.04.3 LTS

Not sure what package this belongs to, but this has to do with trying to suspend the computer.

What I expect:
selecting power off->suspend suspends my computer e.g. turns off screen, turns off fans, etc.

What happens:
In "Software & Updates" Additional Drivers tab, for my GeForce GT 745M, if I select the "Using X.Org X server" open source driver and then I try to suspend, the computer will log off, and the screen will turn black except for blinking cursor in the top left corner. The computer will never power down.

The workaround:
I work around this by selecting "Using NVIDIA driver metapackage" from nvidia-driver-470 (proprietary, tested)
After this, my computer properly suspends.

Thanks for the bug report.

While the broken Xorg driver is installed and the problem is happening again, please run:

  lspci -kv > lspci.txt
  journalctl -b0 > journal.txt

and attach the resulting text files here.

To save time in future, please report graphical bugs by running:

  ubuntu-bug xorg

Files are attached in the zip.

This is the explanation of the filenames:
filename_nvidia: output before I installed xorg driver
filename_xorg1: output immediately after I installed xorg driver (no reboot)
filename_xorg2: output after failed suspend and power cycle

Hope this helps.
Thanks!

Thanks. This is probably an issue with the default 'nouveau' kernel driver. That causes so many bugs that I would always recommend installing the Nvidia 470 driver instead, as you have.

I would not expect a fix for 'nouveau' any time soon as it is not well supported. But if you are using the Nvidia proprietary driver then that won't affect you.

Thank you for the info. In that case I will continue to use the Nvidia driver.
