I have a dual boot machine with Windows Vista Home and Ubuntu 14.04 just recently installed. It has a GeForce 6100 nForce 405 internal graphics processor. In Vista I can set my monitor to 1280x720 but in Ubuntu 1024x768 is the highest that will work. I use an Olevia OLEVIA 23" 720p LCD HDTV LT23HVX for my monitor. I know it says that the 1024x768 is the highest it can do on VGA but like said Vista will do 1280x720, I think even 1280x1024? Any help would be appreciated.

Please open this file
sudo gedit /etc/X11/xorg.conf
Find the section "device" and add this line to it
Option"ModeValidation" "NoMaxPClkCheck"
Now reboot and see if your resolutions are back

Thanks for the answer but all that did was give me dispay errors on restart. I had to restart in recovery mode and it found the errors and sent a report. Any other ideas are welcome, but I'm starting to think I won't be able to change this. – Alex Marten Sep 02 '14 at 01:54

OK remove that line for `xorg.conf`, can you find if you have an Optimus GPU ( I think you do), If so then `sudo apt-get purge nvidia*` (* is not a typo) and try this http://askubuntu.com/questions/452556/how-to-set-up-nvidia-optimus-bumblebee-in-14-04 – Mark Kirby Sep 04 '14 at 06:38
