Latest XFree86 v4.0 crashing (possible culprit sawmill)

Latest XFree86 v4.0 crashing (possible culprit sawmill)

[root]

I want to say that this wasn't introduced with the rpms released the
other day, but I'm still having the problem with them.  I can't really
pinpoint exactly when I started having this problem (except while
working on my last major project for my graphics class).

Here's the problem:

While switching desktops, X completely dies on me.  It's not
consistently repeatable, but I've had to kill the programs it didn't
pull with it enough times to know that something's wrong.

That's all it's doing.  X dies when I'm switching desktops, either by
dragging the mouse, or by clicking the desktop in the deskguide.


Please tell me I'm crazy and that it isn't really happenning...

Just to be sure: Is this about "real" desktops or virtual desktops? AFAIK
mouse dragging only works to switch between virtual ones?

You're crazy and it isn't really happening. *grin*

Seriously, Sawmill isn't the culprit (Listen people: server crashes are
_never_ application bugs :) but it seems to point out this server bug better
than anything else.

If you could provide a gdb backtrace from a static server, that would be
great, otherwise you could send the log and other useful information either
here or maybe better to XFree86.

I'm roughly familiar with gdb, but not enough to really know what I
should be doing to help.  Where should I expect to find the core file,
and what information do you need?  Which log file do you need?

The server doesn't normally dump core. I suggest you build a server with
'#define DoLoadableServer NO' uncommented in either
xc/config/cf/{xf86site,host}.def and run the server from gdb.

Beware that you'll most probably have to do that from a remote machine as you
won't have access to gdb's console otherwise.


> and what information do you need?

Where it crashes :)

Hint: Rebuild the file(s) it shows with makeg to see the actual code in gdb.


> Which log file do you need?

/var/log/XFree86.0.log

But sadly it's only rarely helpful in such cases.
