Check in /etc/X11/xorg.conf, see what resolutions are available.

Re: screen size screwed kubuntu 6.06

Have a similar problem with an Nvidia Go chip in my Dell widescreen laptop.  Found if I edit xorg.cong and simply changed the driver to nv the screen size works perfectly, but as soon as I change back to nvidia driver it stops 2 screen sizes short of the native resolution, in spite of it all being set up correctly otherwise.  I'm using the nvidia-glx debs with the 686 kernel.

Ideas?

No you're not. At,least not if you're using the "nv" driver. I believe that the glx stuff only works with the nvidia driver I may be wrong, I've never tried to run glx without the nvidia driver. Have you installed the linux-restricted-modules package for your kernel? That package is neccesary to make the nvidia driver work.

Well, actually I am, at least when I have the problems when the nvidia driver is selected.  Yes all the required restricted modules packages are selected.  When X starts I get the Nvidia splash screen so it is all working, it's just not picking the correct screen mode.  A single line hack in the xorg.conf to change back to the nv driver and a startx and the right screen mode gets selected, change it back again to nvidia and the wrong screen mode gets selected. 

Running krandrtray doesn't give me the full list of resolution options I should have and that are available under nv, so there's definitely something wrong with the actual nvidia driver that's messing things up, switching to the nv driver works fine (except overlay no longer works, I guess I'll have to manually set that now, geez this is like 1999  all over again...).  This was working fine with the dapper beta and earlie kernel and nvidia driver versions it used, it's only gone pear-shaped since I did a clean re-install.

The other suggestion I have for the original poster is in System Settings/Display to check that the correct monitor has been selected by the system, mine failed to auto-detect so I had to manually select it.  It seems changing the driver also resets whatever you've already selected as the monitor, I'll confirm this at some stage and file a bug if this is the case.

Re: screen size screwed kubuntu 6.06

Actually, I'll take that bit back.  I went and restored a back-up xorg.conf that worked under Mandriva and copy and pasted the modelines and screen config from there over top of the ones generated by Kubuntu, switched to nvidia and rebooted.  Everything is now 100% working, including overlay.

So it looks to me to be an issue with Kubuntu/guidance/xorg whatever with the way it's setting up the monitor or modelines (perhaps the IgnoreEDID setting?).

FYI, here's the before and after of the relevant sections. 

WARNING these will only apply to a Dell Inspiron 1650x1050 laptop display, don't use these numbers on any other screen.  You may however find some clues here as to how to re-write the  generated xorg.conf so it gets things right.
