I was in Ubuntu 20.04 when the screen just froze, and while the mouse still worked, nothing else did.

Nothing works except starting in safe mode. System always freezes within a few minutes.

I've tried updating to the Ubuntu 20.10 (first release beyond the latest LTR), have tried updating various drivers, am seriously eyeballing going back to Mint at this point.

output of lspci | grep "VGA":

07:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] RV516 [Radeon X1300/X1550 Series]

Output of sudo lshw -C display:

The last thing I tried was:

sudo apt-get install fglrx-updates

and I got the following error (which happens a lot with solutions I'm seeing proposed):

Reading package lists... Done
Building dependency tree       
Reading state information... Done
E: Unable to locate package fglrx-updates

Many of the articles appear to be 4-6 years old, so I highly suspect their root cause is different from mine.

I'm a noob, so listing commands and what output(s) to look for to triage further would be appreciated. Happy to get rerouted to an "already answered" link that actually works.

  • trying the sudo apt purge nvidia-* command at the bottom, worked well until I got the following final line: Purging configuration files for nvidia-opencl-icd-304 (304.135-0ubunt u0.16.04.2) ... Processing triggers for initramfs-tools (0.137ubuntu12) ... update-initramfs: Generating /boot/initrd.img-5.8.0-45-generic libdvd-pkg: Checking orig.tar integrity... /usr/src/libdvd-pkg/libdvdcss_1.4.2.orig.tar.bz2: OK libdvd-pkg: apt-get check failed, you may have broken packages. Aborting... About to try the second one, reboot, and get back here. Mar 17, 2021 at 19:35
  • sudo ubuntu-drivers autoinstall No drivers found for installation. Mar 17, 2021 at 19:37
  • Try this answer to fix broken packages first, then try the solution above again. If you encounter booting problems to GUI desktop, try this answer to fix that.
