How to set display resolution

Hi folks,

FC3

I just have a new Philips 190B LCD monitor connected to the box.

# cat /etc/X11/xorg.conf

Code:

.....
Section "Screen"
        Identifier "Screen0"
        Device     "Videocard0"
        Monitor    "Monitor0"
        DefaultDepth     24
        SubSection "Display"
                Viewport   0 0
                Depth     16
                Modes    "1280x1024" "1024x768" "800x600" "640x480"
        EndSubSection
        SubSection "Display"
                Viewport   0 0
                Depth     24
                Modes    "1280x1024" "1024x768" "800x600" "640x480"
        EndSubSection
EndSection

Rebooted FC3 and login KDE as User.

Right-click on desktop to start "configure - desktop" window
Display --> Size and Orientation --> Screen Size = 1024 x 768 (max)
NOT 1280 x 1024

Please advise how to set it.
(remark: the display card can support higher resolution)

TIA

Hi,

The specs list 1280x1024 as the max resolution for this lcd screen, does it support depth 16/24 with that resolution?

The rejection of the 1280x1024 resolution should also be present in the X log file (don't use fedore myself, but /var/log/ is probably the location of this file), it could also tell you why it is rejected.

Hope this helps.

Hi druuna,

Tks for your advice.

I solved the problem by running;

# system-config-display

Previously I mistakenly thought just manually editing /etc/X11/xorg.conf as

Code:

....
Section "Monitor"
.....
        ModelName    "Philips 190B"
......
Section "Screen"
....
                Modes    "1280x1024" "1024x768" "800x600" "640x480"
        EndSubSection
        SubSection "Display"
.....
                Modes    "1280x960" "1024x768" "800x600" "640x480"
        EndSubSection
EndSection
.....

Gave a hard stroke pressing [Ctrl] + [Alt] + [<-](back delete) will reset the resolution. It can't. Even rebooted won't help.
