[SOLVED] "No screens found" with Xorg+nvidia. ibt=off doesn't help.

esuhl · 2022-07-03 20:05:33

A month or two ago, I updated Arch (with no obvious issues), but X started in a low non-native resolution. I'd been slowly troubleshooting, when a subsequent update fixed the problem. Recently, I updated again, and now X refuses to start at all, with a "no screens found" error.

I've re-read the wiki pages, but the only issue I could see was the temporary requirement to set ibt=off, which I did, yet the problem persists.

The PC dual-boots to Windows 10 without issues. I'm using GRUB, the linux kernel, nvidia driver, and XFCE. Instead of using a GUI login manager, the PC boots to a bash shell, where I log in and run "startx" manually.

I don't have an /etc/X11/xorg.conf file, and my /etc/X11/xorg.conf.d/20-nvidia.conf file is entirely commented-out.

I've examined the /var/log/Xorg.0.log file (below), but... I'm not sure where to go from here. Can anyone point me in the right direction? :-)

Please post the output of the following

modinfo nvidia
dmesg

It's not matching the nvidia ddx, so you don't have nvidia-utils installed?

Aha! Thank you so much! dmesg showed that my nVidia GeForce GTX 770 card now uses the legacy nvidia-470xx-dkms driver.

I removed the following packages:

nvidia
nvidia-lts
nvidia-utils
lib32-nvidia-utils
open-cl-nvidia
cuda

I then (re)installed the following replacements:

dkms
nvidia-470xx-dkms
nvidia-470xx-utils
lib32-nvidia-470xx-utils
opencl-nvidia-470xx
cuda

And now I can start X successfully! Thanks again :-)
