Re: No luck reconfiguring resolution options.

[snip example from xorg.conf]
For each depth listed under Section "Screen", my xorg.conf contains
the line:
Modes "1440x900" "1400x1050" "1280x1024" "1280x960" "1280x854"
"1280x800" "1280x768" "1200x800" "1152x864" "1152x768"
after I removed "1024x768" "800x600" "640x480" from each line and
saved the file. However, the only resolutions I can set it to are
those three, which are absent from the list. I've done dpkg-
reconfigure xserver-xorg and modified xorg.conf plenty of times now,
each time explicitly attempting to prevent any resolution below
1152x768 from even being an option, but every time I come back to
1024x768.

I'm using the driver "i810" - an Intel driver for the Intel chip
driving the graphics in my (*sigh*) Dell laptop. I tried replacing it
with svga and vga in xorg.conf and restarting gdm, but both times X
failed to start, so I'm back on "i810" and still unclear about why I
can't use a resolution higher than 1024x768, especially since I used
higher when this computer was running WinXP.

Thanks for this tip.

The tips you've offered all make sense. I'm still a little...shall we
say green? but I'm getting a feel for how things are done, and more
importantly for how to look for things when I'm confused. There are
some snobbish elitists about, but so far the Linux community has been
very helpful and patient with my rookie-ness.
I'll keep playing around, but this far no luck.
Thanks
