WARNING: I sent this message a week ago, but I got no answer. Sorry for this
second (and last) post.
Hello everybody!
I installed -current (1998-01-24 SNAP) on my laptop, with XFree86 v3.3.1
The laptop has a Cirrus Logic CL-GD7548 SVGA chip with 1 MB memory and an
800x600 DSTN LCD panel.
When I start the X server, the screen appears (about) 70 pixel shifted to the
right, with a black border on the left side, and a lot of (waving) horizontal
stripes.
Luckly, if I switch the output to the external monitor connector and than back
to the LCD, it becames perfectly clear and stable, without the 70 pixels offset.
BTW, if I press CTRL-ALT-F1 to switch back to the console while te screen is in
the "weird" state, I get a weird console :) What I mean is that I get an almost
all white console, with whiter characters here and there, but repeated 3 times
in 3 big horizontal stripes.
Of course, if I switch the output the console goes fine...
Moreover, it works perfectly after a suspend (I'm using the SaveToDisk feature
of the Phoenix Bios).
I'm really stymied... Well, that's not a Big Problem(tm), you know, it works,
you just have to remember to switch out then in again the VGA output, but...
Is there any way to avoid this? Any help appreciated. Thanks in advance.
I include here the relevant parts of XF86Config and the X server output:
