I am possibly affected by this as well. Here is my description, maybe it is helpful to someone:
This is a laptop running natty with 2.6.38-13-generic (x86_64) kernel with a integrated Intel HD Graphics 3000 processor (kernel module: i915). Occassionally the display stops refreshing (e.g. clock applet does not refresh), only the mouse pointer can be moved (even so in some cases the mouse pointer cannot be moved). The laptop does not react on mouse-clicks and keyboard events (so switching to a tty is not possible). The laptop is still running and responding, however. Logging in via SSH is still possible and does not show any suspicious cpu/memory usage and no entries in dmesg/kern.log. If I "kill -9" X, gdm recovers, I can log in again and everything works as it should (except that all unsaved work is lost). Mouse and keyboard work again in the newly spawned session. The problem does not happen deterministically, but I found that copying data from a LibreOffice calc spreadsheet causes it nearly every time (90% chance). It does not happen every time, and it happens for other reasons as well. I have a table with 1000 rows, 30 columns, and copy 2 colums to Firefox, gedit, ... via CTRL-C/V.
