Ubuntu 10.04: unable to login after fresh install

Hello All,

I,ve just installed a fresh copy of Ubunutu 10.04, downloaded a couple of days ago. The installation seemed to go fine. However I can't log in: the login screen just seems to reset and asks me for my password again.

It's not an authentication / incorrect password issue. If I stick in a wrong password, I get "Authentication failure".

I've googled around, others report the same issue on the Ubuntu forums, but there doesn't seem to be a fix. Does anyone know of a work around or what the problem is?

Have 9.10, I might end up just installing that instead.

THanks

• what session are you using?

  try to use GNOME or GNOME failsafe from the drop down menu at the bottom of the login screen

  it happens with me when I try to use sugar for my children

  also, I read some complaints about compiz compatibility with 10.04

  Richard : Was using gnome anyway - however gnome failsafe has seemed to fix it. any idea what the difference is between them?

  Richard : yeah i have a crappy video card, could be that it can't handle the default effects

  A.Rashad : it could be the compiz problem then. try to reduce the effects and re-log-in with GNOME once more. and try to check your Video driver, it might be not supported by the default distro, you might need to look for it and try once again

  A.Rashad : I am not sure what exactly is failsafe, but it seems to be something similar to safemode in windows. i.e. GNOME with minimal features to allow the session to start

• Dear Linux user,

  To fix this issue you should reboot Your pc and start choose from the grid recovery ( second line ). chose from the list command promt using root type ---> passwd username enter the new password

  type reboot now

  and enjoy :)

  Nader Barakat : Also this should fix the issue for everyone :)

  kaerast : It's not a problem with incorrect passwords, it's a problem with the session failing on login. That's caused by any number of things, including video problems if it's X or a problematic .bashrc file if it's command line.

• I had this problem and it turned out to be a bug in the xserver-xorg-video-openchrome driver not handling AIGLX correctly. See [Bug 589520] at https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-openchrome/+bug/589520. You will be using this driver if you have VIA video hardware.

  There is a workaround which involves inserting

  Section "ServerFlags"
  Option "AIGLX" "off"
  EndSection

  in /etc/X11/xorg.conf

  Create xorg.conf with just that entry if it doesn't exist (as it probably wont in a new installation of 10.04).

  I hope this helps.

  Cheers,

  Stuart
