Xorg freezes after resume

[Luc Sanselme]

On a eee-pc 1015BX, Xorg freezes after a suspend/resume cycle. I can still login via ssh. Any X application started from a ssh session (after setting DISPLAY) freezes when it tries to read from the X socket (it can be seen with strace). The rest of the system seems to work properly; for example, I can run mplayer in ASCII art.

The additional information attached were collected after a suspend/resume cycle.

The problem is fixed after installing fglrx-experimental-12 (version 2:12.100-0ubuntu0.1).
