I'm using an old Dell XPi notebook PC. It is nice to be able to hook
it up to a "real" monitor and keyboard. It has an "CRT/LCD" toggle
control that works perfectly when I'm just using syscons terminals. It
has three modes, LCD, CRT, and both at once. If it detects the VGA
plug is being used, it automatically goes to CRT only.
The problem is how to set this up right with X. Right now, if I am
using the CRT and type 'startx,' the CRT loses its signal and a
pattern of black and white horizontal lines show up on the LCD. If I
Ctl-Alt-F1 back to the terminal, all is fine. On the other hand, if I
toggle back to the LCD, and with the LCD enabled, type 'startx,' X
comes up fine on the LCD (which it has for years). And if I now toggle
to the CRT from LCD, X comes up on the CRT. It needs some tuning, but
the picture on the CRT looks OK.
Anyone have some clues for me how to avoid having to do the
CRT-to-LCD-to-CRT toggling and still have X work? What would be good
would be to be able to tell X which I'm using so I can get the mode
right (my LCD is 800x600, but the video chip set can handle more
pixels than that). It would be totally cool if X could figure out
which device I was using on its own somehow.
I tried some web and mail list searches, but didn't find anything on
point. Just scrolling through XFree86 documentation didn't really give
me any thing specific with respect to this issue. Has anyone had
success doing these kinds of things? Anyone doing it with similar
hardware? Any pointers to documentation that would be relevant?
Thanks.
