F14 LXDE spin lxdm-greeter does not go anywhere....

[Ranjan Maitra]

Hi,

Just installed Fedora 14 LXDE spin on my trusty IBM T61 Thinkpad laptop.

It was a clean install, however after install, I can not get beyond the
login screen.

Here is what happens:


I input my user name for the Username:  
hit enter
and then my password next to Password:

Both go away, but the big Login screen does not. (Basically nothing
happens). Hitting the quit button to reboot/shutdown causes a flashback
to the first login screen (and then the above process is repeated with
amazing regularity). 

Going in to console mode and logging in shows lxdm-greeter as a process
running. Nothing else is out of the ordinary. 

Any suggestions?

Ranjan

So you can login on the console with the same username and password?

Boot with SELinux disabled to see if it is the culprit. When the grub
prompt appears, hit a key to get to the menu. Then select your kernel
and hit "e" to edit. Select the line starting with "kernel=...", hit
"e"
again and add "enforcing=0" to the end of the line. Then press "b" to
boot.

If it is a SELinux Problem, please tell me what version of
selinux-policy is installed.

Yes, I can. But I have found a strange workaround and that is if I
switch to the console and back: i.e. doing Ctrl-Alt-F2 and Ctrl-Alt-F1
in quick succession.

I added enforcing=0 at the very end of that line and no change. I
waited for at least a couple of minutes and then tried my trick above.
That worked. 

I got some SELinux alerts as before:
SELinux is preventing /usr/sbin/lxdm-binary "unlink" access
on .Xauthority

Also, 
SELinux is preventing /usr/sbin/setfiles access to a leaked
/usr/local/maitra/.xsession-errors file descriptor:

In both cases, the notification does say:
[SELinux is in permissive mode. This access was not denied.]

Note that I have always had my home directory in /usr/local.

3.9.7-7.fc14-noarch.

Strange. This looks like a problem with your hardware and the X server,
seems something goes wrong when LXDM tries to switch the VTs.

Please edit /etc/lxdm/lxdm.conf and change the line
        arg=/usr/bin/X -nr vt1
to
        # arg=/usr/bin/X -nr vt1

The X-Server should then start on vt7 as it used to be in pre-plymouth
times. Does this work any better?

Ok, good to know. I really think it's an X problem.

This is a known problem, but it doesn't prevent you from logging in. See
https://bugzilla.redhat.com/show_bug.cgi?id=635897

Uhh, please don't do that. If will break a *lot* of SELinux rules. Your
home should be /home/maitra.

For a while, I thought it was worse, because my trick no longer worked.
However replacing F7 with F1 does do the difference.

I agree. but it is strange that no one else is seeing it yet....

But Fedora had fixed this problem long ago. It used to be the case that
contexts needed to be defined/restored manually. In any case, that does
not seem to be a problem.
