I think I have the same problem, on an Optiplex 745. If I leave the X session idle for long enough, or if I attempt to do a 'lock session' from the KDE menu, I get a very similar behavior to what you described: mouse clicks and keyboard don't work, although the mouse can still move around the screen, and I can either CTRL+ALT+F1 or CTRL+ALT+BKSP without a problem. This started about a week ago, right after I got dual head up and running on my Radeon. Things were working fine, and then after I installed the 'fglrx' kernel and Xorg drivers and started using the dual head setup, I noticed these little glitches. Since 'fglrx' is from Livna, I just figured it was a bug. In the meantime, I'd rather have dual head and just deal with the annoyance or having to restart my X session every so often. Looking in the Xorg log, I noticed that every time this happens, there's a corresponding pair of log messages: SetClientVersion: 0 9 SetGrabKeysState - disabled I don't know what those mean, but the timing is not a coincidence. If you haven't managed to fix this, would Would you mind trying to do a 'lock session', to compare the behavior of your system? Also, are you using the 'fglrx' driver? Are you using dual head? Also, does anybody else know if this list is appropriate for continuing this thread? Can you suggest a better place to which we could move it?

I never found a real answer, at least partly because I could never reproduce the problem at will. I started to suspect the screen saver and the last time it happened I was able to fix it by killing the screen saver (via an SSH session from another machine). I am not offering this as a definitive solution but it might be worth a look. -- Keith
