There is an easy way around this -- rename (or even delete) the file /etc/ati/atiapfuser.blb. From my research this is a "user profile" which doesn't seem to be utilized, at least in my case. When that files exist, you will see LOTS of entries like:
Xorg 21747 root 103r REG 8,4 0 16387220 /etc/ati/atiapfuser.blb in the output of "sudo lsof -P `pidof X`". But after I 'mv' the file, not long these entries. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to fglrx-installer in Ubuntu. https://bugs.launchpad.net/bugs/910539 Title: maximum number of clients reached Status in “fglrx-installer” package in Ubuntu: New Bug description: X server hits a client limit at a very low value.

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.
