Fedora 10 on Acer Aspire One : no graphical login after updates


After updating my Acer Aspire One via 'yum update' I can no longer log in via the graphical logon screen (gdm).

When I hit ctrl+alt+F2 I can logon via the commandline.

tail /var/secure gives me an output that the logon fails.

UPDATE :

I've added a new user 'testuser' and I am unable to log in with this new user. Not in graphical login, not in commandline...

As root open your /etc/passwd file to see if 'testuser' is really added. Also try to find out what packages got updated, as one or more of these obviously mixed up your system. It is not necessarily gdm who is at fault - the problem is somewhere in the authentication tools.

Yum seems to have some option to undo updates, AFAIK, but I never used that function, so I can't tell the exact way to do it (try Googling on yum undo revert and similar keywords). Other way is to run another update: if one of the updated tools has the bug, then it should already be noticed by a couple of people, so maybe there is a patch already.

Thanks for your reply.

I have the same problem on another laptop and on my desktop, both also running Fedora 10.
I thought it might be a global problem... A bug that was not yet reported and fixed.

UPDATE : there were some updates when running 'yum update' that indicated gdm en gdm-user-switch
But my problem of not being able to log in via the graphical interface is not yet solved.

I'm now running in runlevel 3 and starting the x-server manually with 'startx'. This means however that some services and filesystems are not mounted automatically...

Same problem here

Yes,
This seems to be a global problem.
I'm also affected. I think I saw yum installing anew X server.
and probably some x drivers.


I have Fedora 10 on my T60.

Mine is NVIDIA GeForce 8600 GS on my acer aspire 5920, and the one in the Acer Aspire One I don't know right now...

To recall : both the laptops have the same Fedora-problem after yum update...

I got similar updates for me. However, I login via kdm. So I guess gdm packages should be ok.

This is my xorg.conf :

	EndSubSection
EndSection

I don't understand why changing something here would make it possible to log on in graphical mode ?

UPDATE :

Adding the following changing nothing. Wouldn't understand if it did.

Section "Screen"
Identifier "Screen0"
Device "Device0"
Monitor "Monitor0"
DefaultDepth 24
Option "AddARGBGLXVisuals" "True"
SubSection "Display"
Depth 24
Modes "1280 x 1024"
EndSubSection
EndSection

When you are on cli and do a startx... I assume you get an error starting X.(That was what was happening in my case).
I have my laptop configured for dual screen so I need those "Virtual" entries in my xorg.conf.
Upon digging in the error logs /var/X... I found that it wasnt able to detect the modes for my laptop screen LVDS.
That brought me to xorg.conf because this is where you let X know about modes.

If you're getting *some* error while doing startx... then it would be great if you post the logs from /var/X...
The exact log name will be given in the error that is displayed.

Startx gives me no error... it works fine, like I stated earlier.

I have some new information :
I changed the password of my user 'jonas' from 'jonas' to 'jonaskl'. Now, neither of my passwords work. I can not log in graphically, neither via the commandline.
I'm now logged in as root, cause that's the only way I can get into my system. I guess if I change the password of my root also, I'm totally locked out !

The change of password was writen to the /etc/shadow -file :

jonas:jonaskl:14303:0:99999:7:::
So... any great suggestions ?

Ok sorry for my wrong assumption. Your problem is different from mine except perhaps for the fact that it happened just after
an update.

Since you see that passwords are written to /etc/passwd ... I've run out of suggestions :-/

See if fiddling around with System->Administrator->Users and Groups in Gnome helps.

good luck.

Tried doing that indeed. But that did not change anything.

If there's a way of deleting the password, so I do not need to authenticate myself, there may be a way around.
However, deleting a password is not permitted. A password must be given on creation of a new user or when deleting the password of an existing user also a password must be given.

Tried editing /etc/shadow... read-only... even for root.

What I noticed in my /etc -directory was that there's a gshadow and a gshadow- file. Don't know which one is actually used and by what program but in one file my testuser exists, in the other my user 'testuser' does not appear.
Don't know which passwords are used here...

/etc/gshadow :

/etc/gshadow- :

So... I've tried this one for a change :

started up again in runlevel 5 and at graphical logon screen I changed my keyboard settings...
Guess what... we're back in business. Seemed to be the key-layout after all. Just didn't change it at the right place...
