SUMMARY when switching to another session with Ctrl+Alt+F1 (same thing with F3, haven't tried any others), I get a blank screen. Both of my monitors say there is no input video signal and they go into sleep mode. I can't seem to type any commands, but I'm not sure. Maybe the session is just not logged in or something. At least, neither blindly typing `shutdown -r now` nor the password for the only account on my machine, nor the username + password seemed to do anything. `who` on the main session doesn't show any sessions other than tty2. Switching back to the main session (F2) works fine, but kwin shows a message saying that desktop effects were restarted due to a graphics reset. This is a minor issue, but caused a problem for me when the screen locker showed a message saying something like "the screen locker crashed. You cannot log in to this session. Switch to another session and restart from there". I had to hard-shutdown my PC to get access to it again. STEPS TO REPRODUCE 1. Ctrl+Alt+F1 OBSERVED RESULT no video output EXPECTED RESULT terminal Operating System: KDE neon User Edition KDE Plasma Version: 6.4.3 KDE Frameworks Version: 6.16.0 Qt Version: 6.9.1 Kernel Version: 6.14.0-24-generic (64-bit) Graphics Platform: X11 Processors: 20 × 13th Gen Intel® Core™ i5-13600K Memory: 32 GiB of RAM (31.1 GiB usable) Graphics Processor: NVIDIA GeForce GTX 1060 6GB Manufacturer: ASRock Product Name: Z690M-ITX/ax
This sounds like an issue with Neon. The TTYs are not controlled by Plasma or KDE software, but by lower level code. Sending to Neon. FWIW I cannot reproduce this in a Neon User VM or with git-master Plasma built on Solus on another laptop Are you able to see a terminal login on Ctrl+Alt+F4 or Ctrl+Alt+F5?
this sounds like a graphics driver issue interacting with virtual terminals. which nvidia driver are using?? is it the latest available??

Sorry, I missed your reply. No, F4 and F5 show nothing just like F1 and F3.
issue has something to do with nvida driver, modesetting and framebuffers - all upstream issues so changing this bug report to reflect that this an upstream ubuntu issue https://bbs.archlinux.org/viewtopic.php?id=299997 https://github.com/NVIDIA/open-gpu-kernel-modules/issues/365
I'm not sure that that's the same issue. My GTX 1060 is a Pascal card, which neither supports the open kernel modules nor should be affected by the issue mentioned in the GH issue since it's not a Turing card. Still, it looks like the issue is upstream either way.
