Display settings lost on reboot

dms05 · 07-21-2010, 11:13 AM

I'm running PCLinuxOS 2010.07 (KDE) on my Acer laptop with Intel Mobile GM965/GL960 Integrated Graphics Controller. I have an external Acer monitor that displays at 1920*1080. I have selected my laptops internal screen to be disabled and use the external screen. The PC LinuxOS Control Centre selected the 'Intel later than 810 driver'.

All works well whilst I'm using my system but when I turn off and reboot the settings are lost and I have a 1280*800 display on my laptop and the same on my external screen.

Resetting the Display using Configure your Desktop allows me to reset the external monitors to my preferences but how can I make theses settings permanent?

Use script that do xrandr stuff at startup?

Interesting idea. I will try and see if it's possible to make it persistent!

I'd guess, you can add your modes in ' Subsection "Display" '
This is from PCLinuxOS 2010.07 , /etc/X11/xorg.conf :

Code:

Section "Screen"
    Identifier "screen1"
    Device "device1"
    Monitor "monitor1"
    DefaultColorDepth 24


    Subsection "Display"
        Depth 24
        Modes "1024x768" "832x624" "800x600" "640x480" "480x360" "320x240"
    EndSubsection
EndSection

Thanks for your help. I've checked in etc/X11/ and all the correct entries are in place by default:

Subsection "Display"
Depth 24
Modes "1920x1080" "1600x900" "1366x768" "1360x765" "1280x720"
EndSubsection
EndSection

Section "ServerLayout"
Identifier "layout1"
Screen "screen1"
EndSection

The problem is I configure the screen resolution correctly from the settings offered but it isn't persistent and is lost on rebooting. I use other versions of Linux on the same screen without a problem (Mepis, Mint for example) so it seems to be a problem with KDE.
