Description of problem:
for some reason X will not load correctly. It hangs endlessly with the
default background and an hourglass. i'm able to use ctrl-alt-1 to run
"top". when i do this, i notice that gdmgreeter is using 50% of the
CPU and keeps restarting (it keeps changing its PID). any ideas how to
fix this? my packages were update via rawhide as of yesterday. this
problem has occurred since i first updated from rawhide after
installing FC Core 2 Test 1. any help would be greatly appreciated...
in the meantime, i guess i'll have to keep ssh'ing into the box and
running X apps from it. thanks again...

I'm seeing the same problem - I upgraded from Redhat 9 to Fedora Core
1 with no problems. Then I applied the latest updates using yum, and
now my desktop is screwed. Gnome sits with a blue background and
spinning hourglass as described. KDE just keeps restarting the X
server so I can't even use ctl-alt-F1.

I don't see the high CPU use, but gdmgreeter does keep restarting. I
enabled debugging on gdm, and have attached the relevant bits from my
log file. Howvever, all this tells me is that gdm_slave_child_handler
is dying unexpectedly.

I tried to strace another instance of gdmgreeter while the X server
was up - it traced for a while but then bombed with the following error:
strace: ptrace(PTRACE_TRACEME, ...): Operation not permitted

Any hints as to where to go next would be appreciated!

after installing FC2 test2, i can no longer produce this bug... it
appears this bug has been squashed.
Comment 7 Warren Togami 2004-04-17 07:05:51 EDT
There are at least a dozen different causes for this that may have
been fixed since then.  Please REOPEN only if you find isolate a very
specific cause.
