Comment 6 for bug 894470

i disabled the proprietary driver as suggested in the other bug but had the same problem again.
if i kill eclipse the keyboard and mouse work again but the unity launcher and window decorations are sometimes gone.
i then get compiz segfaults when i kill the lightdm to restart the x session.
i use eclipse 3.7sr1.

i found a forum thread with (what might be) the same symptoms that reports that installing a new compiz version from ppa fixes the issue. i will try that now and report back if the error reoccurs or eclipse is stable for a week.
