Boot process freezes unexpectedly

nathan4 · 2020-04-09 06:37:05

Recently, my computer has shown a black screen after a boot is attempted. I was able to solve this by adding "nomodeset" to the end of the linux kernel line. However, whenever I try to boot now, GRUB freezes after the line "/dev/sdxx: clean xxx/xxx files, xxx/xxx blocks"

I have also tried adding 'random.trust_cpu=on' to the kernel line as described in this post [https://bbs.archlinux.org/viewtopic.php?id=250542], but to no avail.

nomodeset will fail on the graphical.target, can you boot the multi-user.target?
https://wiki.archlinux.org/index.php/Sy … _boot_into

Can you boot it w/o nomodeset?

This seems to have worked, but when I get past that point my display manager (LXDM) doesn't load, even though I have it enabled through systemctl.

seth · 2020-04-09 07:20:59

That's pretty much the point of booting the multi-user.target.

This seems to have worked

w/o or only w/ the nomodeset parameter?

nathan4 · 2020-04-09 07:30:52

Only if I use nomodeset.

nathan4 · 2020-04-09 07:57:24

This is sort of the problem: if I use multi-user.target, I can't boot to a desktop. If I don't, I'm back to where I was before.

The purpose of the multi-user.target boot is to provide you with a shell to start an investigation.

Boot w/o nomodeset, reboot using ctrl+alt+del (should work for at least the multi-user.target) this time using "nomodeset".
Then upload the "sudo journalctl -b -1 | | curl -F 'f:1=<-' ix.io" of the previous (failed) boot and post the link so we can check what's wrong.

The link is to a journal from a boot with nomodeset.

Apr 09 08:32:02 janus kernel: Command line: BOOT_IMAGE=/boot/vmlinuz-linux root=UUID=87cb5146-c096-4072-aa32-9afe35801f73 rw loglevel=3 quiet nomodeset

Chance the value passed to the -b option of journalctl to find a boot without nomodeset but with the issue then post that journal to the pastbin e.g.

sudo journalctl -b -2 #check if this boot has nomodeset if it does
sudo journalctl -b -3 #check again until you find one without
sudo journalctl -b -7 #one without
sudo journalctl -b -7 | | curl -F 'f:1=<-' ix.io

I tried that, and it initially started, but then it got stuck trying to load my display manager. The second time I tried it, it just got stuck on the /dev/sdxx loading screen again.

Can you test the GPU under another OS to rule out a hardware issue?

seth · 2020-04-09 19:35:14

Also try to add "amdgpu.dpm=0 amdgpu.aspm=0 amdgpu.runpm=0 amdgpu.bapm=0"

nathan4 · 2020-04-09 20:07:28

>Also try to add "amdgpu.dpm=0 amdgpu.aspm=0 amdgpu.runpm=0 amdgpu.bapm=0"

I tried, and it still didn't work. The GPU also works fine on Windows.

seth · 2020-04-09 20:08:54

Does the lts kernel work?

nathan4 · 2020-04-09 22:34:49

It doesn't, regardless of whether modesetting is enabled.

seth · 2020-04-10 06:13:22

Wait, the main kernel does boot w/ nomodeset, but the LTS kernel doesn't???
(Again, as soon as you pass nomodeset, you will NOT be able to boot the graphical.target, only the multi-user.target)
