Xubuntu 14.10 and Intel i915

It is very easy to setup Xubuntu on this old laptop.  Unlike the OS (Windows) it replaced, it runs smoothly on the laptop's Core2Due processor and with 3GB memory.  Most hardware on this laptop just works in Xubuntu, with the exception of the Intel i915.  Every now and then, I got a corrupted screen.

After reading up a few posts on online forums, it seems this can be fixed by applying

1) Create a i915.conf file in /etc/modprobe.d with this line

options i915 enable_rc6=1 enable_fbc=1 lvds_downclock=1

2) create a xorg.conf in /etc/X11 with the settings below

Section "Device"

   Identifier  "Intel Graphics"

   Driver      "intel"

   Option      "AccelMethod"  "uxa"

EndSection

This tricks seem to work so far.  I will update this post in few weeks time to let you know if it really gets the job done!
