Intel g45 + Acer 1080p monitor Xorg setting

Posted by Pourya Shahroudi on Nov 22, 2009 in Linux | 5 comments

I have recently bought a new PC. The graphic card is Intel G45/G35. I had a long day trying to configure my Acer 1080p monitor with the graphic card. The problem that I had was that I could not increase the resolution to more than 800×600. I had the problem both in the login screen and when I logged in to my account. Finally I managed to do fix the problem! I am currently using a combination of the settings I found on the web and its working perfectly fine. I’m using the default Intel driver that Ubuntu installs. Intel’s graphic drivers in general seem to be having some bugs in Linux, so If you see any updates for the graphics driver I strongly suggest that you use it. Overall, if you are having problems with your graphics under Linux first I suggest to look into the xorg settings, mainly because you might end up changing what you should not change.

here is the content of my Xorg file:
Make sure to keep a backup of your original xorg file before applying the following setting:

# xorg.conf (xorg X Window System server configuration file)
#
# This file was generated by dexconf, the Debian X Configuration tool, using
# values from the debconf database.
#
# Edit this file with caution, and see the xorg.conf manual page.
# (Type "man xorg.conf" at the shell prompt.)
#
# This file is automatically updated on xserver-xorg package upgrades *only*
# if it has not been modified since the last upgrade of the xserver-xorg
# package.
#
# If you have edited this file but would like it to be automatically updated
# again, run the following command:
# sudo dpkg-reconfigure -phigh xserver-xorg
