No.

Do not add "-listmodes" to the .xserverrc file.

Instead, boot into text mode and on a command line, type:

sudo -u dsl Xvesa -listmodes | more

and you should get a list of supported video modes.

I have a toshiba 110CS, p100 laptop with a similar situation.
I can ONLY get 4 mode color out of it,
so no icons or backgrounds.

Many applications will not run at all,
requiring at least 8 mode color.
MC will run, as well at the shells... thats about it..

Both Xfbdev or Xvesa optons do not seem to help..

Perhaps that is the same trouble you are having with your Dell*..

But according to my specs, I *should* get at least 800x600x256.
The video chipset ....

Kent,
My laptop uses the C&T 65554 chip and it will do 800X600 with 2 meg ram at 24 bit color, you would think that yours would at least do 256 colors. There may be enough differance between the two though. DSL has always worked well with mine so maybe it's a driver issue with yours, although I thought that there was only one C&T driver.

ke4nt,

You could try compiling the Xchips Tiny-X server, which similar to xvesa and xfbdev but for the chips & tech video boards.

Or you could try out this guy's precompiled binary:

and see if it works any better.

In a further attempt to find a solution to my problem, I tried booting with low colour depth (4 and 8). This gave simliar problems as before with errors on boot-up as:

"megaraid: no BIOS enabled WD700C.0 Failed initialization of WD-700.0 SCSI card
line 706: xf86cfg: command not found"

Upon shut-down I get:

"Could not initialize any graphics driver. Tried the following drivers.
x:
no supported color depth found."

The appearance of the screen is like before.

When trying xvesa with the -listmodes arguments from the command prompt with sudo, as recommended by cbagger1, I get an error along the lines of "no password".

Any ideas?
