Binary package hint: xorg

After upgrading to Ibex a problem has appeared where after some activity (10-15 minutes), X will suddenly stop responding to any mouse events - the cursor is still there and will move around, but windows won't change focus and clicking the mouse buttons have no effect (in both the focused and unfocused windows). Keyboard still works fine and I can Alt-Tab between windows. Mouse still moves the cursor normally, just will not click anything.

I have a four-monitor Xinerama setup running the latest NVidia drivers on two 8600GT Graphics cards. This setup worked perfectly in Hardy.

Problem is present in 2.6.27-7 & 2.6.24-19, Nvidia Drivers 177 & 173.

Tried with two different wired optical mouses (logitech and microsoft) and problem is present in both.

Once the problem occurs, the only way to get the mouse buttons working again is to Ctl-Alt-Backspace to restart X. Mouse will work fine for a period of time after that.

Strangely - if I have xev running, it won't respond to any events if the mouse is over the window, but if the cursor is at the same height as the window one screen over to the right, it will show events.

I don't think I see anything in dmesg / syslog / Xorg.conf.

amd64 arch w/ 8 GB Ram.

This is driving me absolutely crazy as my computer is pretty much unusable.
