where DVI-0 is the name of your monitor output (VGA-0, VGA-1, DVI-1) and 1440x900 is the resolution you would like to start up your computer with, to the file /etc/kde4/kdm/Xsetup
hope this helps this setting persists through reboots:-)

First let me say I'm glad to be a new member that has recently made the switch from Ubuntu 8.04 with Gnome to KDE4.1 with (K)Ubuntu 8.10. I was a casual and happy Gnome user for years who didn't used to like the feel of KDE. However, after trying the live CD I'm proud to say that I'm now a convert - or would that be konvert? Great work on the interface! It feels like OSX, looks better than any other OS out there imho and is a nice step up from Gnome in terms of flexibility and configurability.

Now for the problem:
I found that the display settings would not stay at 1280x1024@85Hz after either logging out or rebooting and would revert to 1600x1200 with each log in.

That was driving me nuts so after some reading on various forums a couple of things came to light:
1/ xorg.conf was empty so no solution based on editing that would work
2/ opening 'system settings > display' would set correct resolution so it seems like the settings 'are' saved, just not applied at startup.

The solution:
Adding these few lines (shown in bold below) to the /home/user/.kde/share/config/krandrrc solved it thanks to the second post by ranacc here http://ubuntuforums.org/archive/index.php/t-358236.html.

[Display]
ApplyOnStartup=true
SyncTrayApp=true

[Screen_0]
OutputsUnified=false
UnifiedRect=0,0,0,0
UnifiedRotation=1

[Screen_0_Output_default]
Active=true
Rect=0,0,1280,1024
RefreshRate=85
Rotation=1

That would explain the kcmrandrrc_display_applyonstartup="false" line in the startupconfig file in the same directory. Should it be "true"? Any edits to that file would get overwritten with each boot. The same thing happened when editing the systemsettingsrc file. This problem was present on two systems. One with the intel gma3100 and one with a very old but still capable gefore2mx 100/200 with 64MB.

Hopefully there will be a better solution somewhere down the road but this will do for now. The side effect of this is that my panel size gets reset but I can deal with that. The upshot is that after being lulled into a false sense of security I'm once again far more familiar with Linux than intended but so far have managed to get away with not having to compile anything. Any bets that won't last long. No pain no gain right?

Hope that helps and saves some people from having a few headaches. Imho KDE4.1 isn't ready for terminal shy users like me but when it is it will be quite possibly the best OS frontend/user interface to date. This is a VERY good start!!
