Hello all,
Urgent help required!
I have turned on my Fedora 16 machine today. It booted quite normally
to
the
GDM login screen. When I selected one of my 3 users it started to login
to
the account as usual, but got no further than loading the background. I
CTRL-ALT-BKSPC'd back to the login screen and tried each of the other
accounts. Same problem. I can start a terminal session with CTRL-ALT-F2
and login to any user account in that terminal - and it is from there
that
I am sending this (using Mutt). I have tried googling using a text
based
browser, (but that is quite hard work) and all I have come up with is
this
bugzilla https://bugzilla.redhat.com/show_bug.cgi?id=753666 which
describes my symptoms perfectly (I am also using the nvidia akmod
driver)
but there is no resolution for me in that bugzilla.
Unlike that report I have updated nothing since Sunday (11 December)
and
it
worked fine yesterday (12 December). Here is an extract from dmesg:
[ 39.204161] gnome-shell[1458]: segfault at bc955315 ip 42325db4 sp
bfadd520
error 6 in ld-2.14.90.so[42319000+21000]
Below I list a (long) extract form /var/log/messages. There is some
very
fishy
looking stuff in that, but I have no idea how to fix it. Please help me
to
get
back to a working gnome-shell!
Thanks
Mark
I don't wish to appear desperate - but...
...I am desperate!
Any ideas?
It's a bit of a shot in the dark, but you could try removing the
proprietary nvidia drivers, and rebooting. It would be something like
yum erase \*kmod\*nvidia xorg-x11-drv-nvidia\*
That would probably get you back to the nouveau drivers.
If that doesn't work, there might be a hint in your /var/log/Xorg.0.log

Well thanks for that. I was actually thinking about removing the nvidia
driver.
As it happens, I gave up on the machine for the moment and went to work. I
therefore no longer have physical access to the machine. I can, however
ssh into it. While I was wondering about removing or re-installing the
nvidia driver I noticed that there is a new kernel available in yum
(3.1.5-1.fc16.i686.PAE) so I did a yum update. This will of course cause
the akmod module to rebuild the driver.
I have rebooted, and the encouraging thing is that dmesg now has no
reference to a gnome-shell segfault!
Well that's very encouraging!
Unfortunately I will not be home again until Thursday evening so I can't
actually try to log in to gnome-shell to see if it has worked (are there
any command line tricks to test if gnome-shell is working?).
Hmm. You could run 'ps fax' and look for a gnome-shell process, or a gdm
process (I'm not sure what the login manager shows up as). If you see it
there, that shows that it's running.
HTH,
Rich
