I've got a problem.

Here is my laptop spec :

  • Type: ASUS A43E-VX389D
  • Video Card: Intel HD Graphic
  • Memory: 2 GB DDR3
  • Processor: Intel B950 ( 2.1 GHz, 2MB L3 cache )

I'm using Ubuntu Precise Pangolin 64-bit, with graphic card, detected as Intel Sandybridge Mobile.

Now, I have the following error (see images below):

Error#1

Error#2

Sometimes, it's just partial. Sometimes, I could get 'the error' almost a whole screen.

Could somebody help me out?

FYI, if I maximized the window, the 'error' is sometimes gone. And if it still there, I just minimized/maximized/restored the window till it's gone. And it happens so frequently. To be honest, that's very annoying.

You should report this as a bug (as this site is not the right place for bug reports).

If you log out, click the Ubuntu logo on the login screen, and select Ubuntu 2D instead of Ubuntu from the drop-down menu, then you'll log in to a Unity 2D session instead of a Unity session.

Unity and Unity 2D use different window managers, and it seems likely this is either a bug in the window manager or a bug in your graphics drivers that occurs when using a window manager with 3D graphics acceleration.

In addition to giving you a possible workaround, trying this will also give you information you can use in reporting the bug.

OK, thank you for your fast response Eliah Kagan. FYI, m using Gnome Classic session at the moment. Maybe, yeah, I should report it.. –  thom Jun 21 '12 at 4:17
    
GNOME Classic uses Metacity as the window manager. It could be a bug in Metacity but seems more likely a bug in your drivers if it's happening with Metacity, since Metacity doesn't use graphics acceleration and is therefore somewhat unlikely to introduce such problems itself. –  Eliah Kagan Jun 21 '12 at 4:19
