Quick Tip – Using dual monitor with compiz on Ubuntu with Intel 965GM
One of the most frustrating things of using Ubuntu with my dual big monitors is that I couldn’t run compiz with it. Since I have an Intel 965GM card, due to some mesa driver bug, it won’t let you have a desktop bigger than 2048 x 2048 (summing up all monitors).
I had struggled with this issue multiple times in the past, but eventually decided to just leave it and use metacity instead.
Though, Ludovico Cavedon has posted a fix to that bug on his third party repository. All you need to do is add those repositories to your /etc/apt/sources.list and update. Compiz should then work with textures sizes bigger than 2048 x 2048 on Intel X3100 965 GM card :-)
