[SOLVED] X server segfault after exiting

marfig · 2010-08-07 01:49:51

The X server on my machine always crashes with a segfault generated by a Fatal IO Error 11, when I exit from an X session. Otherwise works perfectly fine. So this really has no apparent impact on my ability to use X. I'm just curious what may be generating this segfault and what I can do to fix it.

This is the report while X is running (startx):

(EE) Failed to load module "vmwgfx" (module does not exist, 0)
(EE) vmware: Please ignore the above warnings about not being able to to load module/driver vmwgfx
error setting MTRR (base = 0xd0000000, size = 0x01130000, type = 1) Inappropriate ioctl for device (25)
The XKEYBOARD keymap compiler (xkbcomp) reports:
> Warning:          Type "ONE_LEVEL" has 1 levels, but <RALT> has 2 symbols
>                   Ignoring extra symbols
Errors from xkbcomp are not fatal to the X server

** (pcmanfm:3974): DEBUG: unable to load icon system-software-install

(pcmanfm:3974): Gtk-WARNING **: Radio group does not contain an action with value '0'

This is the actual segfault when I exit my X session:

** (lxsession-logout:4166): WARNING **: dbus-interface.c:71: DBUS: The name org.freedesktop.Hal was not provided by any .service files

** (lxsession-logout:4166): WARNING **: dbus-interface.c:71: DBUS: The name org.freedesktop.Hal was not provided by any .service files

And this is Xorg.0.log:

Please advise if you need more information. I'm curious what may be generating this segfault and what I can do to fix it.

IIRC that error means you exited it in a not-clean way, f.e. by Ctrl-C from tty1.

marfig · 2010-08-07 02:02:28

No. I used LXDE's logout button.
And before I installed LXDE I'd exit with 'exit' on the last term window.

So you exit, it crashes - can you restart it?

marfig · 2010-08-07 02:07:50

Yup. startx fires up X again, without any problems or anything different showing up in the log.

karol · 2010-08-07 02:24:57

Maybe try to take care of the errors and warnings from Xorg.0.log and it will go away. Looks like it's some vmware stuff, so I won't be of any help as I've never used it.

Try to delete xf86-video-vmware.

marfig · 2010-08-07 09:24:44

Ok, seems to be a problem with the graphics driver (xf86-video-vmware).
Changing my device driver from 'vmware' to 'vesa' in xorg.conf.d, makes the segfault go away.

ekenbrand · 2010-08-07 10:02:32

It happened to me too. Changing video driver is the solution

marfig · 2010-08-07 10:04:39

Thanks for the confirmation, ekenbrand.
