Comment 37 for bug 197153

I've posted some packages to http://people.ubuntu.com/~bryce/Uploads/ for testing, including debs.

These include checks for if xrandr is available (which should help Xinerama users), if the xrandr version is 1.2 (which should help nvidia and fglrx users, and maybe others), and the null pointer check I posted above.

For radeonhd and intel 8xx, both of which say they support xrandr 1.2, I don't think this will fix the issues, but the null pointer check will change the behavior a bit (probably will still crash but in a different spot).

Please test these debs and let me know whether it addressed the issue or not, and what video driver you tested with.
