Widescreen Resolutions for Intel Display Cards In Ubuntu Feisty

Open Up Your Terminal
Install i8xx,i9xx display driver
In order to use higher resolution install updated Intel i8xx, i9xx display driver. It is provided by a package called xserver-xorg-video-intel. This package provides the driver for the Intel i8xx and i9xx family of chipsets, including i810, i815, i830, i845, i855, i865, i915, and i945 series chips.
sudo apt-get install xserver-xorg-video-intel
When this is finished reboot your system
Now you need to go to System>Preferences>Screen Resolution to see all of the new options.
The new Intel driver is still in experimental state. I tried it before, and it did not work. I recommend installing 915resolution instead. From the 915resolution site:
Do a simple
sudo aptitude install 915resolutionrestart, and it should be working. If it doesn’t, you can check the 915resolution site for help (you might have to edit xorg.conf): http://www.geocities.com/stomljen/
I’m using 915resolution to setup the widescreen mode in my laptop, but i have trouble setting different refresh rates for the external VGA output. I have tested the xorg-video-intel driver, but when i set a lower screen resolution, the Xserver is restarted by itself and the screen geometry remains the same.
915resolution worked for me as well at 60 Hz. I have no display problems on a Gateway MX8738 widescreen laptop running three operating systems Ubuntu, Vista and XP Professional.
I have manually added new resolution 1920×1080 for my widescreen lcd and it worked, but the resolution is not permanent and is lost after reboot.
sudo xrandr –newmode 1920×1080 220.75 1920 2064 2264 2608 1080 1083 1088 1130 -hsync +vsync
sudo xrandr –addmode VGA1 1920×1080
It seems to finally work in 10.04 as of Alpha-2 for me. Perhaps I had the option prior to 10.04 but I had not noticed the “mirror option” before. Now I can control both monitors independently through the Display option via software rather than try my luck at the shortcut keys through the hardware and hope for the best.
