Issue setting KDE resolution - Fedora 12, ATI, Dell Inspiron 8600

[Lets Go Canes]

Hi all.

Installed Fedora 12 on a Dell Inspiron 8600 laptop, dual-boot with Windows
XP.  I want to use a different resolution than what KDE comes up with by
default (default is ~1900x~1200, I want 1280x800).  However, the KDE tool
for changing resolution doesn't appear to do anything.  I googled around,
and found suggestions for using xrandr; that attempts to change the
resolution, but the only working, usable resolution with this method
appears to be the default.  The desired resolution works under Windows XP.

Any suggestions?

Thank you for the suggestion.  I installed system-config-display, and
after running it, if I use the KDE tool to change the resolution,
it now attempts to do so.  Unfortunately, I get the same results as
I got with xrandr; most of the resolutions just give me a black
screen.  If I use system-config-display to change the resolution,
I also get the same result, with the added problem of having to
boot single-user to delete the xorg.conf file to get the display
back.

Try system-config-display -noui

You shouldn't have to do that, simply switching to a text-only console
should give you a working display so you can issue commands.

e.g. CTRL ALT F3

I was able to correct this by adding "nomodeset" to the boot command in
grub.conf.
