Problem with screen resolution in F8



The first time I logged in after installing F8, the background picture covered the entire screen but the top menu bar and bottom task bar only extended about 2/3 the width of the screen and the bottom task bar was not at the bottom of the screen but about 1/2 the way up.

After playing with the screen resolutions, I have 1152x864 60Hz and the bars extend all the way across the screen and the task bar is at the bottom.

I have 2 problems:
1) The 1st 1/2 inch of the screen is missing of the left side which, for some reason is really bugging me.
2) The resolution I really want is 1280x1024 75Hz  This is a dual boot machine at 1280x1024 75Hz is what I use in Windows

Can anyone give me some ideas as to why I can't get my desired resolution?

Below is some info from Xorg.0.log and /etc/X11/xorg.conf.

Thanks,
Steve

I have an ATI Radeon X800 PCIE graphics card and a generic 20" LCD monitor.

If I look in my Xorg.0.log file I see that the resolution I want is listed but then I see this line for output DVI-1:

(II) RADEON(0): Not using default mode "1280x1024" (hsync out of range)
(II) RADEON(0): Not using default mode "1280x1024" (vrefresh out of range)
(II) RADEON(0): Not using default mode "1280x1024" (vrefresh out of range)

and when it prints out the probed modes for DVI-1, 1280x1024 is not there. A similar thing happens for DVI-0 and this time the reasons given are:

(II) RADEON(0): Not using default mode "1280x1024" (bad mode clock/interlace/doublescan)
(II) RADEON(0): Not using default mode "1280x1024" (bad mode clock/interlace/doublescan)
(II) RADEON(0): Not using default mode "1280x1024" (bad mode clock/interlace/doublescan)

However, when the probed modes are printed this line shows up:

(II) RADEON(0): Modeline "1280x1024"x75.0  135.00  1280 1296 1440 1688  1024 1025 1028 1066 +hsync +vsync (80.0 kHz)

Near the bottom of the log, it says:

(II) RADEON(0): Output DVI-1 using initial mode 1152x864
(II) RADEON(0): Output DVI-0 using initial mode 1152x864

My /etc/X11/xorg.conf has this in it:

Section "Screen"
        Identifier "Screen0"
        Device     "Videocard0"
        Monitor    "Monitor0"
        DefaultDepth     24
        SubSection "Display"
                Viewport   0 0
                Depth     24
                Modes    "1152x864" "1024x768" "800x600" "640x480"
        EndSubSection
EndSection
