I believe nvidia proprietary driver does not yet work with xserver 7.10

[Romain Janvier (romain-janvier)]

I know but i set xserver packges 'on hold' before 7.10's upgrade and all working fine with Unity 3.4.

Hm... Romain are you sure you don't happen to have an incomplete update of some libraries regarding unity? Unresolved symbol errors (for nux::InputArea in your case) are usually happening, if you don't have correct library-versions installed. Stuff like that happens during development of unity (and nux) on our development-systems. Could you check you updates with synaptic or dpkg? Or did you happen to install unity (and nux) from source once?

[Romain Janvier (romain-janvier)]

... yes i installed unity from source. I think it's the problem, because all my dependencies are up to date and i've got the same issue with 3.4.4.
thx,
Romain

This issue happens when you have a latest nux installed on your system and there is an api break (I think) as I have seen many other reports with the same type of error message in terminal especially people who were using nux from the unity daily ppa. I am closing this bug as invalid as this issue does not happen with the Vanilla unity setup.
