by the way, as the evtouch driver is the same as etch/lenny/sid, did you eventually notice the problem also with earlier versions of X.org? I've been using the driver for a long time without much problem, I just started having those random freezes one month ago (but I can't really tell if they are due to an xserver-xorg upgrade...) > > This is on a Fujitsu P1000 laptop with the 0430 (Fujitsu > > Takamisawa):0508 (USB Touch Panel).

Let's see if it got fixed in the meantime. hmm... testing it here with not much luck actually. I just need a few click^Wtouches to freeze X. I'm now running X in gdb, I'll also try to give it a run using efence or libsafe or even valgrind with a debug-enabled version of the driver. I hope to find some evidence as looking at the code there's nothing particularly obivious. -- mattia :wq! -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
