A few days ago I went out and bought myself a nice widescreen 19" LCD with both DSUB and DVI connections. It's been a pretty interesting experience using the LCD. At first I only had the DVI connection plugged into my system and nothing would get displayed on the LCD until Xorg loaded (the monitor switched to "digital" at this point). So I decided to plug in the analog connection and have both connected. Suddenly avi files which played before no longer displayed anything on the screen (I tried using Xine, Mplayer, and Totem, interestingly avidemux did display them). As soon as I pulled the analog Dsub connector the movies played fine.
I assume that the system needs to switch to digital mode to play the avi files and for some reason with the analog connector plugged in there's no auto-switching mechanism? Can I keep both plugged in to get the best of both worlds?
p.s. Using SuSE 10.1.
