Smooth Compositing

Xorg configuration is relatively straightforward, but to ensure you have smooth compositing effects from Compiz on the Intel 945GM, you will need to add these lines into your Device section:

Option      "DRI"                    "True"
Option      "NoDDC"                  "True"
Option      "XAANoOffscreenPixmaps"  "True"
Option      "EnablePageFlip"         "True"
Option      "RenderAccel"            "True"
Option      "AccelMethod"            "XAA"

And ensure that you have the following somewhere:

Section "Extensions"
   Option "Composite" "Enable"

Native 1400x1050

Install the driver for i810.

 pacman -S xf86-video-i810

Edit your xorg.conf file

Section "Device"
   Driver "i810"
 Section "Screen"
     SubSection "Display"
               Depth     16
               Modes "1400x1050" "1280x1024" "800x600"

Install the 915resolution Intel hack tool from the community repo:

 pacman -S 915resolution

Logout of X (CTRL + ALT + Backspace). Then run:

 915resolution -l

Select the modes that you want to overwrite, like 49 and 45 in this case. If your needs differ adjust accordingly.

 915resolution 45 1280 1024 16
 915resolution 49 1400 1050 16

Verify your changes:

 915resolution -l

Start X again a you will get 1400x1050 and 1280x1024. Remember, you'll want to load 915resolution at startup.

Edit /etc/conf.d/915resolution :

 # Enter the VBIOS mode to patch
 # Enter the desired resolution
 RESOLUTION="1400 1050"

Then add "915resolution" to the DAEMONS line in /etc/rc.conf.
