My screen resolution does not remain the same after logout/reboot

[davidKlinux]

I am on kubuntu 11.10
The basic screen resolution was 1024*768. I change it to 1280*1024 (with the "system manager" and I save as "default") (and it works) but when I logout/reboot it switch again to 1024*768... How can I fix that ?

your hardware might be reporting that its perfered size is 1024^768 you can force a size by adding a line to your /etc/kde4/kdm/Xsetup file

you want to add an xrandr command it will look something like xrandr --size 1280*1024 . depending on your exact hardware setup it may be slightly different. i have posted about this before (more detail)but after a few min of looking thru my post history i can't find the exact post.

Thanks but here is my xsetup script :
#! /bin/sh
# Xsetup - run as root before the login dialog appears

#xconsole -geometry 480x130-0-0 -notify -verbose -fn fixed -exitOnFail -file /dev/xconsole &

/sbin/initctl -q emit login-session-start DISPLAY_MANAGER=kdm

Do I have to add "xrandr --size 1280*1024" ? Or is it in a different file ?

you would add it to that file. check that your xrandr command works as expected by running it in a terminal first.

edit:

 xrandr --size 1280x1024

should work for you notice the 'x' not a '*'
