After the things I did in https://bugs.launchpad.net/ubuntu/+source/linux- hwe-5.13/+bug/1964711/comments/7, I am now facing a worse problem.
My computer no longer recognizes my display correctly. Since the boot screen, the resolution is the minimum available (1024x768). I think my system no longer selects the correct driver for my graphics card. Running "sudo lshw -c video" yields the following: ``` *-display UNCLAIMED description: VGA compatible controller product: Navi 10 [Radeon RX 5600 OEM/5600 XT / 5700/5700 XT] vendor: Advanced Micro Devices, Inc. [AMD/ATI] physical id: 0 bus info: pci@0000:03:00.0 version: ca width: 64 bits clock: 33MHz capabilities: pm pciexpress msi vga_controller bus_master cap_list configuration: latency=0 resources: memory:40000000-4fffffff memory:50000000-501fffff ioport:3000(size=256) memory:50300000-5037ffff memory:c0000-dffff ``` Running "lsmod | grep amd" prints nothing (it used to before) and "dkms status amdgpu" also prints nothing. I tried uninstalling the drivers I installed and also tried installing drivers from different source. I tried to look for issues in my BIOS settings. All to no avail. If I don’t find a solution to this, I will resort to completely re-installing Ubuntu 20.04. I have luckily completed a full backup before. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1964711 Title: [amdgpu] Locked Ubuntu is frozen and cannot be unlocked To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-hwe-5.13/+bug/1964711/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
