Re: Can not change screen resolution (Fedora 5, gnome)

Hi all,

It seems like I am not able to change my x server
screen resolution from
the default to anything higher than that (I want
1280x1024 with (16 or
24 bit color depth). I have just freshly installed
fedora 5 and running
gnome window manager. I have tried changing the
resolution with
System->Administration->Display (the resolution and
color depth options
that I want, are listed in the drop-down box), it
prompts me to
logoff-logon, I exit the x server and start x again
and see the same
resolution (same with restart). I also tried editing
xorg.conf file
myself with no luck.

My xorg.conf file content is below. Fedora seems to
recognize my monitor
and graphics card correctly (at least their names
are correct in
xorg.conf).

I will greatly appreciate any help.

Thanks,

Up to what resolution does your monitor support?

Apparently it only supports up to 1024 x 768

Change these according to your monitor's specs.

HorizSync 30.0 - 81.0
VertRefresh 56.0 - 76.0

And also verify that your monitor supports up to 24 or
even 32 bits.

If it does then change the DefaultDepth to 24 and in
the modes section add 1280 x 1024 and try it again.

You might have to shutdown the machine and/or restart
it for the changes to take effect.

DefaultDepth 16

Viewport 0 0
Depth 16
