I recently got a new HP Firefly laptop and installed Arch Linux from scratch. Everything works great except one very specific but critical issue:
I'm a teacher, and when I project my screen in extended mode (I dont know if the problem happens in mirrored as well, but I need extended view) using Google Slides in Firefox, the screen freezes during the presentation after a short time — typically between 1 to 3 minutes.
What happens:
The presentation freezes; I can’t move to the next slide using arrow keys or the mouse.
However, if I switch windows with Alt+Tab and then return to the presentation, the slide jumps forward, indicating that the input was registered but the screen just wasn’t updating.
What I’ve tried:
Checked `journalctl ---eperr` during the freeze – no relevant errors or warnings.
Installed the full `linux-firmware` package — no change.
Switched to the `linux-lts` kernel along with LTS linux firmware — issue persists.
Tried two different cables: direct HDMI and VGA-to-HDMI adapter — same behavior.
Reproduced the issue on both a projector and a regular monitor.
I am on a standard wayland KDE desktop environment. Any idea how I could fix this?
