I have a Philips 166V3LSB/00 LCD monitor connected to a box with Ubuntu 12.04 LTS.

user@host:~$ lspci
00:00.0 Host bridge: Intel Corporation 82945G/GZ/P/PL Memory Controller Hub (rev 02)
00:02.0 VGA compatible controller: Intel Corporation 82945G/GZ Integrated Graphics Controller (rev 02)
...

The monitor is supposed to support 1366x768 (16:9) but I cannot get System Settings/Displays to even offer anything but ubiquitous 1024x768 and 800x600. I tried removing ~/.config/monitors.xml and re-logging in but that did not help.

Update (1):

I tried forcing modeline to Xorg.conf (added Modes "1366x768" "1024x768" "640x480"), but as a result:

  • resolution os still the same
  • System Settings/Displays now offers only 1024x768 (it previously offered 800x600 as well)

Here is my current xorg.conf and Xorg.0.log.

Any more ideas?

you could try forcing a modeline in your xorg.conf file

be careful, if your card doesnt support, you can have some serious issues, make sure you make a back up of that file before you begin to edit it.

check this out for more information: https://wiki.ubuntu.com/X/Config/Resolution

its possible, that your video driver does not support the resolution and aspect ratio that you desire.

Unfortunately even modeline did not help. I have updated OP –  Alois Mahdal May 18 '12 at 17:24
    
this is old but it mentions optimizing your graphics chipset: ubuntuforums.org/showthread.php?t=1130582 –  supermariolinux May 20 '12 at 1:08
