Ubuntu 9.10 add screen resolution

[Twinkie]

The idea here is that my Dell Latitude D520 can support a much greater desktop resolution and I need to finish making this laptop look good for the boss. This is another hurdle keeping Windows on these computers to me. If I get this one working I will do the same on a Latitide D630 next. My background is Windows guy who switched to ubuntu about 2 years ago on every computer I can now. Hopefully I will understand all the helpful comments I get back here. Thanks in advance.

Running clean install of Ubuntu 9.10 and there is no /etc/X11/xorg.conf file nor can I find the xorg.conf anywhere else on my system. Any ideas?

Hi,

Same happend to me also (it was Ubuntu desktop 9.10 x64) when I tried add new mode as root (sudo -i). After I logged out to my regular user account "xrandr --addmode" finished successfully.

Hint:
Also ensure yourself that new resolution which was created with command "xrandr --newmode" really exists. This can be done when you call just "xrandr" without arguments. You should see it in output list.
