No, I just have to figure out why I have a two faced OS... One side (gui) telling me that it cannot find the screen resolution, but the other side (console) telling me via Xrandr that it is finding it just fine.
Maybe I need to go ahead and get off of Mate 18.04.x but then I lose my compiz stuff and will have to figure out how to get it back into Mate 20.04.x Or I go to something that is running Wayland and get Wayfire going, and then get a modern equivalent to compiz, but I have a lot on my plate right now so need to get it cleared off. Regarding screens, these wide screens are the pits for doing large documents. Also for screens of list of sensors (my WeeWx site) But a repurposed 1080 x 1920 works great with the long axis being vertical now I can open a legal or even letter sized document and read it without having to scroll down the page because it goes off of the screen. The one plus thing about this 3440 x 1440 screen is I can get a regular letter size on the screen without making the text ittybitty... That is a plus, but legal does not quite cut it, oh I can get it on there but it is kind of font smalled... I am thinking that this screen set to 1440 x 3440 would be great for doing text and still have space for other things either at the top or the bottom. Need to check into the LED replacement strips for the screens that sounds like a good project. I have several laptops that are headed that direction might as well get a kit and start finding out what is involved. Too bad I am no longer up in the NW or I would join you guys at that screen repair party... Hope all is well out there, we see your smoke here... So I guess we can sorta feel your pain...
