Problems with Twinview, Metamodes, and resolutions.

I have a problem with Twinview and resolutions. This is my situation, I downloaded a game the other night called Trigger. When I launched Trigger my right screen went blank and the left screen played the game properly, when I stopped the game the right screen turned back on and everything was fine. Upon rebooting though a problem has occured. Both screens are up and functioning, but right after the login the right screen turns off. I have done a bunch of research on this and it appears others have had problems too, but don't post there solutions.

http://kubuntuforums.net/forums/inde...=7804.msg31452

After performing some experiments I have found the problem to be somewhere in the metamodes line of my xorg.conf file. I used to have a line like the following:

Option "Metamodes" "1280x1024,1280x1024;1024x768,1024x768;1280x1024,NULL;1024x768,NULL"

But in order to keep both screens working I had to take out every option but one:

Option "Metamodes" "1280x1024,1280x1024"

The xserver seems to use any listing that has a NULL first? Why?
Is this just a situation that effects KDE?

I also found a post that claims you can change between metamode resolutions by using the ctl-alt-(numpad)+/-

http://wiki.serios.net/wiki/NVIDIA_T...aming_in_Linux

I tried this but it didn't work. Is there a way to changes between listed metamode resolutions?

I have included my complete xorg.conf for reference in case I have missed something in other sections that could be to blame.

Well I followed some advice given in another forum. Evidently my xorg.conf file was a bit wrong so I was told to start over and build a new xorg.conf with the commnad : nvidia-xconfig --twinview

Anyway I did this and it still gives me problems. If I have any metamode listed with a NULL option it will only use these. However I can now CTL-ALT-(Num Pad)+/-. But it will only cycle through the metamode options with NULL, the second screen never activeates. Here is a copy of my new xorg.conf file.

Again, everything works great until I login in. I'm beginning to think my issue lies within KDE itself. Before my problems started I installed the game, but I also tried to reset the monitor power off time increment through the display manager in KDE. This must have had some effect on a setting. It must be a file that gets read in my personal profile for KDE? I don't know anything about the details of this. Does KDE keep display settings too? Does KDE keep these settings in a profile somewhere? I think I have the problems fixed with Xorg.conf I just need to tackle the KDE thing?

Well it is definitely with KDE because I created a new user and both screens work just fine, and the display manager works. This tells me the problem has to be in my /home/"user"/.kde directory somewhere.

Anyone have any ideas what config file I need to look at?
