Ubuntu gnome session does not start

[Nithin]

Any ideas how to debug this? No reply on ubuntu forums for this question.

I tried deleting all .gnome* folders and rebooting.

Thanks,
Nithin.

[Edit] .xsession-errors says, something about setuid and setgid. see 4 posts below.

[Edit2] I am able to login with a newly created user and this doesn't have any issues.
It prints the same setuid and setgid errors for that user too but it goes ahead.

I had the same problem after installing 7.10 as a VM w/VirtualBox. Hal was not recognized either.

forgot to mention, if i run gnome-session in the xterm that opens, it works fine.

Did you look in ~/.xsession-errors after it fails?

This is what it says.

The setuid/setgid message is pretty straight forward but I don't know what would be setuid or setgid by default that shouldn't be.

The second message about startkde failing to start suggests that it's trying to start KDE instead of Gnome for that user.

 

[Nithin]

yeah. i tried both. this log was with kde selected. if i select gnome it says "Executing gnome-session failed". Is there a log for gnome-session which can tell why it failed?

 

[Nothinman]

Well there's definitely something in your home directory that's causing it to fail since the new user works fine, what did you change recently?

 

[Nithin]

no idea. this was a fresh install of ubuntu. i played around with desktop effects and nvidia driver settings. but it was working. and then suddenly
it stopped.

 

[Nothinman]

No idea really, you might've found a genuine bug since that's not something that should be easily broken.

 

[Nithin]

ok thanks. i'll file a bug.

I noticed similar errors when I was troubleshooting compiz-fusion...

apparently the setuid messages are ok. i get that even on a working gnome session.
