I'll have to check that out some time (too many need-to-do-now-or- shortly) projects). Last time I fiddled everything was too big, but then I was using a 1920x1080 monitor, so probably video card sending out 1920x1080 and the increased scaling was hitting the max. > > across some old notes and correspondence: had video issues where > > sometimes get a rainbow type overlay and sort of micro-pixelated: like > > looking through a screen: can see the display, just not clear.

(FWIW the KVM switch has been behaving, or at least as far as I know: no random switching while I've been in here the past several days.)

Humans tend to remember the real good stuff or the real bad stuff -- which is also why I tend to ignore the super-glowing reviews or the absolute horrible ones. Tons of bad: take warning! Anyway, back to X11 and Wayland. Around here I'm going with Wayland where I can. Why? Admittedly I'm following the leader: the Ubuntu, Raspberyy Pi people, etc., have determined it's the way to go. Are they right? I have no idea other than they have a lot more knowledge in this stuff than I ever will so I'll coattail on their learnings. I think part of the big whinings of Wayland is it isn't backwards compatible with X11 (as I understand it some updates have made some compatibility). ...I've run into the lack of compatibility: Kaffeine (older TV/audio/video utility) doesn't work with Wayland, so I run it on older versions on Raspberry Pi's. TVHeadend - one of the current utilities -- does run great on Wayland. The author of Kaffeine quit updating and support years before I started using so it's not going to be coverted. > ..Doesn't really explain why all of a sudden it will chirp/switch > channels, other than a Gremlin got fed at the wrong time.

KM> Well, if all else fails maybe they have tech support.... They do, they were somewhat helpful but it sort of fizzled because the whole thing would work for a while (like I said up there somewhere it has been behaving for probably a week if not two weeks). > Get caught up (ha!)

Years ago I gingerly removed the wires and cables between the desk and the wall.

KM> DOS has its virtues. I'm glad to have started with DOS (2.11): using the command line trained me to think out to get the desired action as opposed to simply clicking a small cartoon. Admittedly clicking the cartoon is easier than all that typing: I've got a cartoon I click on to remotely reset a device on another computer.
