Whats common among Skype, Opera, OpenOffice in Ubuntu ? Whenever I open these applications I get logged off and shows back me the login screen. This started happening since the 10.10 upgrade.

Forgot to mention :

  1. Yes, its x64.
  2. Each time I open these applications, the UI shows and then crashes.

I started each app & logged the last few lines of /var/log/syslog after each crash. Looks like something to do with sound drivers ?

I have a similar problem - but only with Skype, and it's random. –  RolandiXor Jan 7 '11 at 5:10
    
I don't have this problem....maybe it's peculiar to x64? –  hbdgaf Jan 7 '11 at 5:43

Maybe your x-server crashes and restarts. Did you have a look at /var/log/syslog ? –  Simon Jan 7 '11 at 8:15
    
Some apps may not have been upgraded (Java?). Check your sources. –  Takkat Jan 7 '11 at 9:03
    
Ive added the logs here : looks like the sound drivers are crashing them ? –  anjanesh Jan 8 '11 at 4:46

When you are presented with the login screen, it means your X-session crashed. You should investigate your logging, maybe it is a conflict with another package.

should be a comment, doesn't answer the question. –  RolandiXor Jan 8 '11 at 10:51

I had exactly this situiation on Ubuntu 10.04 x64.

  1. Fresh installation of Ubuntu
  2. Nvidia X-driver through Ubuntu Software Center
  3. Opera and Skype through Ubuntu Software Center

And after that Ubuntu began to log me out right after accepting licension agreement in Skype and Opera.

I went to System->Administration->Update Manager and did a full update, then reboot and everything works ok now!

I was able to find the fix for this from a bug report. If you have "xfs" installed (I think it's some kind of xfont server or something), you need to remove it.

Removing that package eliminated the problem completely for me.
