[Bug 246269] Re: Switched from vesafb to uvesafb, but uvesafb can't work without v86d

[captn]

Until somebody decides to fix the Intel fb driver ;-) you have to patch the VGA BIOS
( Read http://dev.gentoo.org/~spock/projects/uvesafb/faq.php )

e.g .for 1280x800:

    * wget
'https://launchpad.net/ubuntu/hardy/+source/915resolution/0.5.3-1ubuntu1/+files/915resolution_0.5.3.orig.tar.gz'

    * tar xvzf 915resolution_0.5.3.orig.tar.gz && cd
915resolution-0.5.3/ && make

    * sudo cp -a 915resolution /sbin/

    * read README.txt

    * sudo 915resolution -l gives me
Intel chipset detected.  However, 915resolution was unable to determine the chipset type.

    * for my chipset fgrep Chipset /var/log/Xorg.0.log
(II) intel: Driver for Intel Integrated Graphics Chipsets: i810, Mobile Intel GM45 Express Chipset,
(II) intel(0): Integrated Graphics Chipset: Intel(R) 965GM

    * forcing 915resolution -c G965 -l works

   * insert
/sbin/915resolution -c G965 54 1280 800

   in the /etc/init.d/module-init-tools file just before the line
# Loop over every line in /etc/modules.

   * be happy
