Can't set 1360 x 768 resolution

[pelikan]

Ok here is what I have now. It still boots into 1024x768 somehow. This is actually a very interesting process though. I enjoy learning more about this and appreciate the help.

Thanks, I did read that guide. Spent hours in it, actually. I haven't posted everything I've tried. I added modelines yesterday and it didn't boot. I'll try again as per your instrucions.

Edit: Yes the HorizSync is correct. Got it from xvidtune.

Edit: Okay tried your xorg.conf. It booted, but in 1024x768:

Obviously I'm also just crawling the web for possible solutions.

Is your monitor connected via VGA or DVI (or something else)?:
http://forums.nvidia.com/index.php?showtopic=73027

If you only have that single LCD connected, try disabling the Twinview options in xorg.conf.

Uninstall the Nvidia-driver via "Additional Drivers" and rename/remove the xorg.conf, then

1.) try default "nv" driver (gets used automatically after the above steps)

2.) try 173er-version of the Nvidia-driver (install them via Synaptic if not offered via "Additional Drivers)

2.) try the proprietary drivers offered by the Ubuntu-X-Team:

Thanks for the suggestions. Using the NV driver, I was able to use xrandr to add a modeline and then set 1360x768 via the Ubuntu menu/System/Preferences/Monitors. That's a great start.

The only problem is the screen is shifted to the right by about 10%. I was able to adjust my monitor a little, but not enough.

[Green Moon]

If your monitor supports it, you can try using the 'auto adjust' button if it has one. (I have that option so it adjusts perfectly every time the screen's out of range).

[pelikan]

Thanks Green Moon. My "Auto Adjust" button doesn't do anything, unfortuantely.

I tried xvidtune, but get an error message when applying settings.

[Krytarik]

I wouldn't stick to the "nv"-driver, its performance is rather poor, it doesn't provide hw-accel, this was just a try, if its driver-related, obviously it is.

Try one of the remaining options next, 173er and Ubuntu-X-Team.

[pelikan]

The 173 driver offered a max res of 640x480. I changed the xorg.conf as follows and it rebooted into 1024x768. Something here is helping a little. Not sure what, exactly.

I installed the latest driver from Ubuntu-X. It give me an option to set 1360x768 in nvidia-settings. But when I set it, my screen goes blank.

I've been trying various xorg.conf configurations but nothing has worked so far.
