Hi,
I have a fresh installation of Trixie with LXQt on a P16s Gen4 AMD.
Periodically (more than once per hour), the whole desktop becomes
unresponsive. Windows can't be moved or typed into and the clock doesn't update.
The mouse pointer still moves, the caps lock LED still operates, audio
continues to work (vlc playing through pipewire) and I can change virtual
console using <Ctrl><Alt><F1> etc and type into that virtual console.
<Fn><Backspace> still puts the computer to sleep, and after waking up it can
be unlocked and functions normally. This is currently the only method I have
found to continue working.
Restarting xfwm4 from another virtual console does NOT help. The problem
goes away after restarting lightdm, but this is obviously not an adequate
solution.
Volume and screen brightness adjustments using the function keys still work.
Keypresses and and mouseclicks entered before suspending seem to be queued
and processed after waking up and unlocking. This feels like it should be a
clue to what is getting stuck.
I haven't managed to find any relevant log messages in dmesg, syslog or
Xorg.0.log.
linux-image-amd64, firmware-linux, mesa and fwupd are from backports. fwupd
says the BIOS is up to date, having successfully applied one update. It's
been doing this since before Christmas, across several kernel versions.
Any ideas for what's going on or how to fix it, please?
Thanks,
Roger
