I 'm having a problem with Ubuntu 16.04, on Asus UX303LA. I currently use the Arc theme but sometimes, when I boot up, the theme does not load properly and the environment looks like the Ambience theme (with a wrong font...).
This is how it looks like:
and this is how it should look
I can't find any kind of "regularity": sometimes it happens, sometimes not. Most of the times (let say, 4 out of 5) it works properly. To solve the problem it's enough to log out, but it's annoying...
Maybe it's related, maybe not, but (again) sometimes (say 1 out of 10), when I shut down, it takes 60-90 secs to have the system turned off, while usually a few seconds are enough (I replaced the HD with a SSD).
I know that it seems confusing, but at the moment I can't be more specific :(
