HOWTO: intel 945 Resolution

To get this working install the i810 and 915 resolution

    #emerge 915resolution xf86-video-i810

If you are running the business edition or have removed the unstable keywords from /etc/make.conf you will need to run the following command to resolve the "masked by keyword" error.

   # echo "sys-apps/915resolution ~x86" >> /etc/portage/package.keywords

Replace ~x86 with ~amd64 if you are using 64bit Sabayon.

type 915resolution -l

    #915resolution -l

To set a resolution type

    #915resolution 58 1280 800

If your monitor resolution is not listed go to 915resolution file and edit it /etc/conf.d/915resolution

    replace="'58 1280 800 24'"

From a terminal type

    #915resolution 58 1280 800

Than Restart X

   ctrl+alt+backspace

or

   #/etc/init.d/xdm restart

An aside to the above steps if you would want to have 915resolution startup when you boot the system next time you nee to the following

   rc-update add 915resolution boot default

This will make 915resolution startup every time you reboot as a daemon process.

OOPS! Just in case your X fails to start follow these steps as root

   $ Xorg -configure

Now and xorg.conf.new file would be created in your directory(/root). Move/Copy this using the following command [NOTE: If you want you could back up the existing /etc/X11/xorg.conf file before the copy]

   $ cp xorg.conf.new /etc/X11/xorg.conf
