Etch - PS2 mouse clicks stop working until X is restarted
I run Etch on a desktop PC, AMD X2 processor, 2 GB RAM, 'stock' kernel. If I let the computer idle for a few hours, sometimes when I come back the PS2 mouse clicks are no longer recognized. I can hotkey around with the keyboard normally, and the mouse pointer moves normally, but mouse clicks are not registered by anything.
The only solution I've found is Ctrl-Alt-Backspace to restart X. When I do that, mouse clicks are once again detected as normal.
I don't know if it matters, but typically when I leave the computer idle it is running pptpconfig (to establish a VPN connection to work), IceWeasel, and rdesktop (logged in to my Windows machine at work).
