Re: X server freeze/crash problem

Hi,

I can rlogin into the laptop. The kernel works, interestingly, it is a 
bit bogged down. Top shows no process consuming cpu, but load is high. 
After a bit it setteld, I can even type this email.

ps -ax shows no "X", or xinit process running.

I thus tried to run "startx" from remote. It recovers and I get a 
working X session!


Then I run the incriminated application, again, it crashes. I get on the 
console:
xinit: connection to X server lost
X connection to :0.0 broken (explicit kill or server shutdown).
wmaker warning: got signal 1 - exiting...

then high CPU usage which I cannot trace if not when looking at "uptime" 
or "top", no particular process consumes it however. After a while it 
goes down and everything is fine again.
