Title:
maximum number of clients reached
Status in “fglrx-installer” package in Ubuntu:
Confirmed
Bug description:
X server hits a client limit at a very low value. Somewhere around
95 clients. This is very easy to hit and I have hit this limit
frequently since upgrading to 11.10. This has not normally been a
problem in decades of running linux.

Unity and compiz seem to have an inordinate number of windows open.
uptime was a mere 19 days.
I am not running google chrome, lastpass, or MinimizeToTray which have
been blamed for this problem elsewhere.
On a related note, the screensaver can take a very long time to let
you unlock the screen (and actually displays the desktop to prying
eyes before hiding it and displaying the prompt). Last time I
needed to unlock, it would not display the password window. I
switched to a console window and killed it. It has been mentioned
that switching to console and back may free some x server resources.
I have 16GB RAM in this machine.
