Black screen after update on both Gnome and KDE

Support
1

After updating to 21.2.1 on 2 different laptops, one Gnome and one KDE, both boot to a black screen. I have had this problem before on the KDE laptop and my solution was to switch to the 5.4.x kernel. Unfortunately, that is no longer a solution as the problem now persists with 5.4, 5.10, and 5.14 kernels and is also now affecting both Gnome and KDE.

I’ve read tons of posts, lots of Wiki pages, and have attempted to fix this on the KDE system by reinstalling SDDM, switching to LightDM, and back again to SDDM.

Both systems have nivida and I strongly suspect that’s the culprit.

I’m out of ideas and must ask for help. Thank you.

I might not be the one able to solve the problem, but providing the output of

inxi -Fazy

would be helpful.

Exactly right, I forgot after hitting my head against this for the last several hours :joy:
Here’s the inxi, and this is from after restoring from Timeshift. If I need to re-apply the update that causes the issue then I can fetch this again from TTY.

5.14 is eol. Switch to a supported kernel:

sudo pacman-mirrors --fasttrack 5 && sudo pacman -Syyu 
sudo mhwd-kernel -i linux515

Then reboot into 5.15 (tap Esc during boot to show grub)
Double check your running kernel is not 5.14 then remove it:

uname -r
sudo mhwd-kernel -r linux514

Since 5.4 and 5.10 have the issues maybe try 5.15 kernel…
Settings Manager → Kernels → Install linux515

Tried this exactly but still, black screen. Live booting and restoring from Timeshift again, something in the update is not playing well with me I guess.

I’m running Manjaro 5.10.141quad core Intel ,7 and got a failed password attempt and black screen after reboot. TTY works and I attempted to update and reboot and got a black screen with login page black , and then black after typing password. Tried startx but didn’t do much .must’ve been something in the update … please help
