Update broke unity

[Lars Noodén]

Binary package hint: unity

I've been running with Unity for several weeks and it's been fine until today. (May 25)
After running 'apt-get upgrade' today, I can no longer use the Unity desktop.
The exact error message is:

   It seems that you do not have the hardware required to
   run Unity. Please choose Ubuntu Classic at the login
   screen and you will be using the traditional environment.

What info is needed to fix this so that I may again run Unity?

Logging back out and logging in again eliminates the error message and allows unity to run.

[Lars Noodén (larsnooden)]

Sometimes (about 25%) the graphical session is started as Gnome rather than Unity, despite no change on my part. Logging out and then logging back in while explicitly choosing unity restores Unity.

Again, it's an intermittent problem and not something I can cause to happen on demand.

[Kent Baxley (kentb)]

Which version of unity are you running currently? According to what's posted in the bug report, it looks like you are still at:

unity-3.8.12-0ubuntu1

unity-3.8.14-0ubuntu1 is the most recent version:

https://launchpad.net/ubuntu/natty/+source/unity/3.8.14-0ubuntu1~natty1

...have you updated to the latest unity yet and have things improved?

[Lars Noodén (larsnooden)]

Things have improved, but as mentioned it is an intermittent problem. It last happened a few days (reboots) ago.

[Kent Baxley (kentb)]

Thanks. Can you provide the output of lspci -vvnn and lsmod from this machine?
