Virtual console not available on F1-F6

travnick · 2023-02-15 10:43:26

Today I'm facing some X11 issue (probably after yesterday update, fortunately wayland is kind of working), so tried to switch to virtual console on F1-F6, but none was working.

I mean, there is no login prompt, only a few last lines of boot process.

How to start debugging it?

The /etc/systemd/logind.conf is untouched, all options commented out.
System us up to date (right now).

Using Plasma, Nvidia, there is also Intel gpu on board.

Are you actively using the intel GPU? If not blacklist it or disable it in your UEFI. That will be the primary reason why your VTs don't work. https://wiki.archlinux.org/title/NVIDIA … grated_GPU

That was it! Disabling GPU in bios solved the issue. But is there any other option to fix this? I'd like to have intel gpu available in second X server.

V1del · 2023-02-15 11:30:59

How do you intend to be doing that? The fact that the virtual console is not available means that you do not have a display attached to the integrated GPU and using the integrated gpu on a secondary X server for other purposes seems counterintuitive and likely not really useful.

You can avoid it by going to an older kernel that doesn't have the framebuffer breaking patch (5.19.x and earlier, afaik current LTS should also still qualifiy) or patching the kernel to remove the change that caused this: https://bbs.archlinux.org/viewtopic.php … 0#p2076510

I do not have attached screen to intel gpu yet. But planning to set up multiset with a TV. But anyway, TV will not be available for "work usage".

Thanks for the link. Nice bug/issue/patch ;/
