1) Safe mode is expected to fail because it disables graphics drivers.
2) Live session all working fine.
3) Graphics working but not able to start a terminal.
So the only problem here is the last one where you couldn't start a
terminal. Did you try Ctrl+Alt+T ? Did the shell respond to mouse
Here are logs from 3 separate type of boots (actually I had to reboot at
least 20 times, because I had a lot of crashes/hangs):
1) USB safemode boot (since the normal USB boot didn't work ~ 5 times)
2) USB normal boot (it worked, don't know why, but I'm not complaining)
3) normal installed boot
We can't read crash files. You need to use the 'ubuntu-bug' or 'apport-

The attachment in comment #16 shows Vulkan is now working, but only with
software rendering(?) so that's going to be slow...
Please run these again:
lspci -k > lspci.txt

glxinfo > glxinfo.txt

Here's the vulkaninfo. I got lucky, since the entire GUI hung shortly
after (don't think it's related to running this specific command
though).
Reverted the Wayland (GDM) change, so it's stock behaviour. And yes, I
switched back to stock config and kernel.
Will try to USB live version shortly.
Oh I see you started with Ubuntu Server.
Please:
1. Don't disable Wayland. Wayland should be enabled.
2. Answer the previous question: After you have switched back to a
'stock' config and kernel, what does vulkaninfo report?
3. Try booting desktop Ubuntu from USB:
Sorry for the late reply.
tonight I installed the full ubuntu-desktop package (with a "clean" test
user) and experienced crashes/hangs and other weird behaviour with the
stock setup. When I disabled Wayland in GDM3, it got a little better,
until that had issues as well.
Note: I went from an 7+
Before the upgrade it was an Intel GPU.

I don't know much about AMD GPUs but from what I've seen there is
usually only one kernel graphics driver that works for a given GPU.
After you have switched back to a 'stock' config and kernel, what does
vulkaninfo report? Does the "bad performance" persist?

am currently using AwesomeWM ( https://awesomewm.org/ ) with LightDM.
- when I ran the vulkaninfo this time, I temporarily switched back to 'stock'
config (which is radeon, not amdgpu). So that might be correct. Should I switch
to amdgpu and run it again?

OK so multiple problems there, which may have the same root cause:
* Your shell/compositor seems to be causing stalling.
* vulkaninfo says your GPU is "not using the AMDGPU kernel driver:
Invalid argument (VK_ERROR_INCOMPATIBLE_DRIVER)"
Sounds fundamentally like the kernel graphics driver isn't

Already tried out some different things:
- Tried the latest linux kernel
- Fiddled with amdgpu & radeon kernel module options
- Tried running the amdgpu kernel module instead of radeon
Had to SSH into the machine to do anything (usually the system locks
