[Bug 315845] Re: Graphical glitches in Intel 915GM when using hotkeys

[Martín Melado]

I tried with a Jaunty LiveCD[ (Alpha 2) and the result is even worse,
when using a hotkey the same white square with garbage appears, and then
the whole screen is filled with garbage. I made a video too:

** Description changed:

  Binary package hint: xserver-xorg-video-intel
  
  Usually, when I press a hotkey or a combination of them (for example,
  turning on/off the wireless, increasing the brightness...) a little icon
  appears in the top left corner of my screen, just like most laptops. It
  doesn't look like a software function, as it works in the pre-OS stage
  too (BIOS, etc).
  
- Problem is that when I am in Ubuntu, instead of these little icons I get
- a white square with garbage in them. This is not the real problem, as
- they are just icons. The problem is that when this square disappears, a
- strange glitch runs over the screen for a moment. It's hard to describe,
- so I recorded a video: http://vimeo.com/2776629

  Also, when this happens, I get these new lines in Xorg.0.log:
  
  (II) intel(0): I2C bus "CRTDDC_A" initialized.
  (II) intel(0): I2C bus "CRTDDC_A" removed.
  (II) intel(0): I2C device "LVDSDDC_C:ddc2" registered at address 0xA0.
  (II) intel(0): I2C device "LVDSDDC_C:ddc2" removed.
  (EE) intel(0): underrun on pipe B!
