I have a Ubuntu 22.04 machine with a older amd graphics card (details below). As a bit of background it was running on Linux Mint for a year and a half. After some trouble with corrupting the hard drive I switched it to Ubuntu a few months ago.

The last time it booted correctly, 3 or 4 days ago, I think I ran an update in the background while playing some games. Then I shutdown and tried starting it again a couple of days later. Now I can't boot into the ubuntu desktop. It boots into a screen with a blinking cursor and I can get to TTY with Ctrl+Alt+F2. I am also able to SSH into it.

I have done some looking and tried a couple of solutions. I have tried starting Xorg manually using startx, but that didn't work. I have also tried using nomodeset on the grub config to get it to boot and that give me an error. I tried reinstalling the ubuntu-desktop. I also tried to boot under the previous kernel, but seemed to have the same problem. I looked at the xorg logs but only seemed to find the one from the last time I got in it, and the one I tried to start manually. I have had trouble finding anything similar that is on a recent version of Ubuntu. I have continued to try to run any ubuntu updates to see if it is fixed with any patches.

I think this might could be a problem between the kernel and the GPU driver, but that is just a lead from something I read where there could be issues with newer kernels and the amdgpu driver.

I have used various Linux distributions for years, but am not an expert. With that I have reached the end of my knowledge and Googling ability. So any help would be appreciated. I had just gotten this install set up the way I wanted and working pretty well, so I don't really want to reinstall, especially since the os seems to work except for the GUI.

    Worth having a look at the logs to see if any other information is available that you can add to your question: ubuntu.com/tutorials/…

  • Thanks, I pulled the Xorg log file and added it to the question. There is something about a segmentation fault and that the server was aborting. I do remember doing a bit of research on that message earlier in the process, but I didn't have any luck. I don't know enough about how the display stuff works to figure it out from the error alone.

I was able to get back into a GUI. I don't know if this is the best solution, but it got me back to were I can login and evaluate. It also confirms a suspicion I had about it being driver related.

I followed a link on an answer about AMD graphics drivers where you could install them directly from AMD (I am guessing these are possibly the proprietary drivers). I ended up at the AMD Support Page were I was able to pick my graphics card, and then download a .deb package to install. I used scp to copy it over to the affected machine and used dpkg to install it.

After installing the .deb package I ran the amdgpu-install script that actually does the install. amdgpu-install Documentation

After running that I rebooted the computer and the login came up. So I guess it is working now, and was something to do with the graphics drivers conflicting with something.
