Each and every time I boot Ubuntu 16.04 the Ubuntu experienced an internal error window comes up. This is a fresh install of Ubuntu on a selfbuild machine (AMD / 64bit). The error pops up every time seconds after I logged in and before I actually could do anything.

I've searched the internet and found a couple of bugs like this one but those I found all seem to have been fixed.

The title of the Error reads: unity-settings-deamon crashed with SIGSEGV in up_exported_dae (can't read more since there is no word wrapping).

Since I suspect this having to do with the graphics card: It is the MSI GTX 970 used the machine.

Edit: There I one more thing I noticed when booting: The purple screen appears pretty fast but then seems to be somewhat locked. I have to wait a couple of seconds before I can actually type in my password.


Bring your system up-to-date, reinstall the unity-settings-daemon and reboot your system:

sudo apt-get update
sudo apt-get upgrade
sudo apt-get install --reinstall unity-settings-daemon
sudo reboot

This should already solve the issue.

  • Thank you for your answer. I followed your steps and it seems the crash window doesn't show up anymore. But still the purple window hangs for about 10 seconds before I can enter a password, which is a bit of a nuisance but might be something for another question. – Mats Jun 23 '16 at 3:36
  • Yes, 10 seconds are pretty long...you should open a new question... – Neni Jun 23 '16 at 5:57
