It feels weird to just jump into a generic Linux community and ask a question. It’s nice being so small - kinda like the internet used to be.
Anyway, I’ve been running Linux servers for decades but only recently switched my desktop. I first tried Debian 12 and I’m now on OpenSUSE Tumbleweed - I switched in the hope of getting newer drivers and maybe fixing this issue.
I have a HP laptop with onboard Intel graphics and an external monitor connected with USB-C. In general it works great - until it doesn’t. From time to time the external monitor does not wake up after a suspend. Normally turning the monitor off and back on will cause some sort of driver reset and it comes back. Once or twice this has not helped and I’ve had to reboot.
I’m running Xorg as Wayland on Tumbleweed won’t start on t his machine. Wayland may have worked with Debian, I don’t recall. I don’t think it’s worth listing details of my versions as it’s happened on two distros and through a couple of minor updates to Xorg on openSUSE. It happens with KDE or LXDE.
Any suggestions?
I ran into this with HDMI on motherboard, not always though. My remedy was, since I had KDE connect on phone and PC, that I run a display shut down and wake command from the phone. It seems to wake something up in the OS
