My Ubuntu is being very very irritating after upgrading to 14.04. Every once in a blue moon, certain glyphs just disappear from the screen.

Every once in a while, (even as I'm writing this question), all my i's are disappearing, with nothing being shown instead.

This is a system-wide problem, some screenshots from Firefox, Nautilus, etc:

How do I fix these errors?

I have the nVidia graphics driver installed right now, but even with a pristine install (with the nouveau driver, this problem was there)

I have seen similar problems with 14.04. They seemed to be fixed in 14.10, and even better in 15.04 (this latter, specifically regarding nVidia cards). So upgrading will probably be worth a try.

The underlying problem seems to be a bug within Unity itself. I have not encountered anything like it on XFCE, KDE or Cinnamon. If you do not wish to install a full system (maybe on a second partition?), you could try one of these desktop managers, see if it plays better with your graphics card.

HTH.

  • I have a strong doubt that it could be unity itself too, although I don't know how to verify this. Anyways, thanks for the answer. – kumarharsh Jun 22 '15 at 08:27
  • @kumar_harsh There are instructions on installing another desktop manager here: http://askubuntu.com/questions/65083/what-kinds-of-desktop-environments-and-shells-are-available You can have both Unity and Gnome-shell (for example) installed at the same time, and switch from one to another in the login screen. – ALAN WARD Jun 22 '15 at 10:00

    Thanks for the links. I'm sure someone will find them useful. (*I'm already aware of those things, just not motivated enough to go through the hassle of changing the DE again* :P). As it stands, Unity has been buggy for quite some time and makes me throw up a little, but Gnome3 is not so good either. Have given LXDE a try a long time ago (looked stable, but badly dated UI). But this lamentation is for another post anyways, so let's stop it at that. – kumarharsh Jun 22 '15 at 11:47
