Fedora KDE - Can't save Display Settings


I have just installed KDE 4.4 on Fedora 12 in addition to GNOME. The default Display resolution is the highest available. I changed it to a lower resolution. However, when I reboot, the resolution switches back to the default setting. Please help.

Setting a permanent display resolution ( as root ) :

Please open a terminal window and type : 1) su

2) system-config-display

... Your new settings will then be saved.

# yum install system-config-display

.. will provide /usr/bin/system-config-display

KDE Display Resolution

Thanks I did that and now the settings are saved. However, the resolution of the Login Screen has also changed. This was not the case with GNOME. Please help.

nothing to do , AFAIK.

Thanks for your help. However I find that the Refresh Rate gets set automatically at 75.1 Hz with the result that the scroll bar on the right side of a window goes slightly out of the screen. If I manually change it to 70 Hz, the screen is OK but I can't save it. Also Refresh Rate is not found in system-config-display.

Please help.

It should be possible to change it in /etc/X11/xorg.conf .
Example ' Section "Monitor" ' :
Code:
Section "Monitor"
    Identifier "monitor1"
    VendorName "Generic"
    ModelName "1024x768 @ 60 Hz"
    HorizSync 31.5-48.0
    VertRefresh 50.0-70.0
EndSection
Can also be used : VertRefresh 70.0-70.0

you need the - after su
su = root with user $PATH
su - = root with root $PATH
the two are VERY different on fedora

The command can be : 1) su ( see post #10 John VV )
2) gedit /etc/X11/xorg.conf

( You will get 'Permission denied' when you try to execute
the text file with the command : /etc/X11/xorg.conf )


... Or you can copy xorg.conf to /home/<username>/
Edit it, and : 1) su , 2) chown root:root xorg.conf
3) cp -a xorg.conf /etc/X11/

..
