Second monitor / display stopped working after update (20250515, nvidia, x11, plasma)
This is part 2 of https://forums.opensuse.org/t/second-monitor-display-stopped-working-after-update-20250211-nvidia/182626/1
Summary
Last february I updated to Tumbleweed 20250211 (Linux 6.13.1, Plasma 6.3, QT 6.8.2, NVIDIA 570.86.16), and my external display stopped working when using X11 and Intel graphics. I reverted to my pre-upgrade snapshot (kernel was 6.11, that’s all I know) to keep using my monitor, hoping it was a bug to be solved after some time.
Yesterday (2025-05-19) I decided to upgrade, and found out that the problem persisted.
- Built-in laptop display always works.
- External display works OK in Wayland.
- External display does not work in X11 if using the Intel internal graphics (set with
sudo prime-select boot intel).- If set up as an extension, it shows a black screen, and I sometimes can move the cursor but it then freezes.
- If set up as the main display, it shows whatever the built-in was showing, but frozen.
Using Wayland is not an option for me due to one of the long-lived Plasma in Wayland significant issues: native Wayland windows cannot save and restore their window positions (20-year-old bug?). My workflows need many windows (mostly browsers) in many Virtual Desktops in many Plasma Activities, and I rely on the browser windows spawing in the desktop where I last left them. Wayland just opens the all the browsers in my current desktop, and then I would need to manually reorder them each time I need to close Firefox.
I tried forcing the reinstallation of all nvidia-related packages, with no luck.
My current solution is to force use of the NVIDIA graphics with sudo prime-select boot nvidia. There might be battery and performance trade-offs (I preferred leaving display GPU for CUDA processing only), but that’s what I have now.
Just for future reference, and in case someone faces the same problem, below I add some notes on what I inspected looking for problems.
