Weird error (bug???) on my screen

Asked by thom on 2012-06-21

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 )

and I'm using Ubuntu Precise Pangolin 64-bit on Gnome Classic session, with graphic card, detected as Intel Sandybridge Mobile. Now, I've the following error (I uploaded the screenshot in an image hosting) :
1. The error start appearing -
2. I scrolled down, the error fullfill the whole window's browser -
3. I clicked restore button, the error disappear -
4. I clicked maximize button -

Sometimes, it's just partial. Sometimes, I could get 'the error' almost a whole screen. And happen frequently. FYI, if I maximized the window, the 'error' sometimes gone. And if it still there, I just minimized/ maximized/ restore the window till it's gone. Its all information I could give. Hope someone could help me out..

I am still trying it. If, this help, so it solved (although by sacrificing the compiz, it's OK with me).. Umm,, sorry, but may I know the decision of my problem?

thom (iamthom) said : #9

Ups,, I exactly forgot to ask these :
1. Is it still possible to enable some effects?
2. I just set 'nomodeset' in a moment ago (on the fly) . In the next boot, should I set the boot options again?

FYI, So far, the error doesn't appear yet. Thankyou for your help & your kindness.
