Problems with Screen Resolution

[Wilson, Richard]

All,

I just found the hardware settings under KDE that allow me to change the screen resolution, but it doesn't allow 1280x1024 -- it has 1024x768, 800x600 and 640x480.  Any ideas where it's coming up with the permitted settings?

Thanks,

Rich

First, my apologies, this is only partially a KDE issue, but I am hopeful that one of you can help me with this.

I have just upgraded my workstation from Fedora 12 to Fedora 14 and am now running KDE 4.5.5-1.

My Flat Panel monitor supports a native mode of 1280x1024 and this is what I have historically run it at under previous versions of Fedora.  When I upgraded to Fedora 12, I had similar problems getting the resolution to 1280x1024, I had to use system-config-display and create an xorg.conf file and add nomodeset to my kernel boot line in grub to get it to work.

Fedora 14 has deprecated system-config-display; if I add nomodeset to the kernel line, I don't get a login screen and everything I've tried so far has not worked -- at least I have 1024x768 resolution -- with Fedora 12 it defaulted to 800x600.

I cannot find the controls in KDE to adjust the resolution -- I found them under Gnome, but the "maximum" permitted was 1024x768.  Perhaps I am missing some KDE package that covers this.

Below is my newly created and modified xorg.conf file -- any insights/suggestions are greatly appreciated!

Thanks in advance,

Richard Wilson
