Welcome :)

I’m on Pop!_OS 22.04 LTS and up to date.

I shutdown my computer with no problems last night. Today I decrypted my drive with the on-screen prompt and it followed into a solid-grey background; My 3 accounts were not displaying. Rebooting has done nothing regarding the problem. The only notable thing I’ve done is install drawio and thunderbird from the pop shop.

Despite this issue, I was able to press [Enter] and input my password successfully. Everything else seems to be running hunky-dory.

I read through my syslogs while scritching my chin, but I honestly have no idea what to look for this time. I scanned through my entire post-boot log entry to no avail, but I’m also a… linux noob.

Help please q.q

    Can you go to a TTY (CTRL+ALT+F2 for example), login there, and then show the output of journalctl -b 0?

    You can share it online directly from your terminal by using the termbin service (https://termbin.com/ ), ie if you do:

    journalctl -b 0 | sed -e 's/your_username/[censored_username]/gi' -e 's/your_hostname/[censored_hostname]/gi' | nc termbin.com 9999

    then as a result you’ll get a link of the form https://termbin.com/SOME_CHARACTERS that you can then share with us here.

    You have to replace your_username and your_hostname with respectively your username and hostname inside the sed command there (basically a search & replace on the output of journalctl) so that they get censored out of the logs before they get shared on termbin.

    Also, make sure you have netcat installed (otherwise you won’t be able to use the nc command):

    sudo apt-get install netcat

      Thank you for the response :)

      Do I change the bit, [censored_username], with my username or some unknown variant of it, or is that a command to censor the username?

            You have 2 displays (your laptop and your Dell monitor) and an NVidia GPU but you also seem to have an AMD APU? What laptop do you have? I haven’t encountered that case before but maybe there’s some way in the BIOS to disable the AMD GPU.

            But before that, can you try to kill Xorg with:

            sudo pkill -SIGKILL Xorg

            and remove and then reinstall your Nvidia drivers with (be careful with the spaces, there’s no space between nvidia- and *):

            sudo apt remove nvidia-* system76-driver-nvidia
sudo apt install system76-driver-nvidia

            and then reboot with sudo reboot.

            Maybe a reinstall of the drivers like that will solve the issue by itself.

              Ehhrrm yes, so about those 2 displays…

              My desktop is connected to my dell monitor and my samsung TV so I can watch stuff in bed, but it’s always off and I never thought my log-in page was appearing on that monitor considering it isn’t enabled… but it is, just for that instance.

              So, that mystery is resolved.

              But it’s unwanted. The second monitor isn’t active. Despite being on single-display mode, it still activates my other monitor, but ONLY for the log-in (Samsung is ‘on’ but no signal any other time). I tried fiddling with ‘~/.config/monitors.xml’, but that didn’t go well haha…

              Regarding the two GPU’s, I’m glad I wasn’t just trippin’ on myself - that looked weird, right? But I haven’t encountered a single notable issue I can trace back to it. ‘nvidia-smi’ is displaying happy numbers, my high-demands are being met. I’m hoping to ignore it until it becomes a major culprit down the line.

              Regarding drivers - I’ve actually already had to reinstall my Nvidia drivers since the ones I had were causing constant crashing. Apparently a common issue. At the very least, it did not resolve my issue. Hopefully the above revelations help though :)

                Oh my bad so both were external monitors, don’t remember why I thought one of them was a laptop screen. At least the issue got narrowed down a bit. I haven’t touched GNOME or GDM in years so I’m not sure but shouldn’t you also copy your monitors.xml to /var/lib/gdm/.config/? There’s also this about changing that file and which assumes the existence of a gdm user under which the gdm process runs but I’m not sure if that’s applicable to Pop OS: https://discourse.gnome.org/t/how-do-you-configure-your-displays-for-gdm/13762

                About the AMD APU, if it’s not causing any issues it’s probably not worth the hassle to disable it in the BIOS (if that’s even possible), I’m not familiar with those setups but modern Nvidia GPUs can switch to the integrated GPU to save power and that’s normally supported on Linux.
