I'm new to the community, but have been using Ubuntu MATE since it started. I'm currently running the OS on 2 Laptops, both of which are HP Elitebook 8440p and a Homebrew Dual server, one is an i7 3770 and the other is an i3 3240, both of these run Plex also.
My issue is with the HP Elitebook 8440p Laptops, as once I've installed 22.04LTS, I came across a very annoying screen issue, no tearing or blank screens, but each time I move the mouse, the screen goes dim and then a few seconds later after stopping moving the mouse, the screen dims.
Has anyone else had this issue? I had Kernel 6 HWE installed, but on 5.15 the issue isn't there. Does 22.04LTS run the Wayland system or is it still X11? I'm trying to nail this issue down and hopefully get a fix for it.
If anyone can point me in the direction of a cure I'd be very happy, also apollogies just in case I've put this thread in the wrong section.....
