[Solved] startx freezes, apparently at a low level

I'm running Arch on a Dell Latitude E5470 with hybrid Intel and AMD graphics.  Up until recently, things went fairly smoothly, with amdgpu and a pretty standard X setup.

Recently, I updated, shut down, resized some partitions including by btrfs root and home partitions, and booted to Arch.  It booted fine (and I can read and write to / and /home), but when I ran startx, nothing happened, just endless rows of dots.  Running 'X' or 'Xinit' just freezes until I forcefully kill it from another tty.

Looking through .local/share/xorg reveals nothing interesting.  I'm pretty sure the logs are old, since they don't seem to change when I do attempt to start X.  Either that, or X fails so early it never starts writing...

I have tried removing my xorg.conf.d, running startx as root (which worked, roughly, up until recently), uninstalling amdgpu, reinstalling xorg-server and the Intel video drivers, and messing with boot / initramfs / etc.  It seems to be fairly low-level, since changing drivers doesn't do anything (I think it even tried to start with no video drivers at all), but it seems to be above the kernel level, as dmesg doesn't reveal much.

Any last resorts to try?

check /var/log/Xorg.0.log (also watch timestamps to ensure it's not old)

What is the output of 'lspci -nnk'? Any messages on dmesg after you kill X or xinit?

seth: All of the xorg logs were old.

R00KIE: Dmesg shows an amdgpu-related kernel oops during boot, nothing when I try to start/kill X.

I've switched to Linux-LTS, that seems to have solved the issue.  Looks like it was a kernel bug?

If it is a kernel bug you should report it upstream, if this problem is something that not many people experience (or report) then it will take longer to get it fixed.
