[Bug 1467274] Re: [HP Pavilion dv7-4272us] Display glitches occur

  Thread Previous • Date Previous • • Thread Next 
** Summary changed:

- [HP Pavilion dv7-4272us] Xorg radeon.dpm=1 causes glitches
+ [HP Pavilion dv7-4272us] Display glitches occur

** Description changed:

- Setting radeon.dpm=1 keeps causing glitches every time the display
- changes from the IGD to DIS and vice versa.
+ Display glitches occur every time the display changes from the IGD to
+ DIS, and vice versa.
  
- It may be related to the HDMI audio, which I tried to turn off using
- radeon.audio=0.
+ I'm trying to _keep the DIS GPU *turned off* in order to save power and
+ keep this laptop cool.
  
- Below are the lines from the kernel log having to do with snd_hda_intel
- (which shouldn't be there when radeon.audio=0).  I'm trying to _keep the
- DIS GPU *turned off* in order to save power & keep this laptop cool_.
- 
- I can't tell who keeps turning the DIS GPU back on, but I'd love to know
- how to keep the DIS GPU locked OFF.

+ I can't tell who keeps turning the DIS GPU back on, but I'd love to know how to keep the DIS GPU locked OFF.

Title:
  [HP Pavilion dv7-4272us] Display glitches occur

Status in xorg package in Ubuntu:
  Incomplete

Bug description:
  Display glitches occur every time the display changes from the IGD to
  DIS, and vice versa.

  I'm trying to _keep the DIS GPU *turned off* in order to save power
  and keep this laptop cool.

  I can't tell who keeps turning the DIS GPU back on, but I'd love to know how to keep the DIS GPU locked OFF.
