There seems to be a bigger problem with hybrid graphic cards. After getting the kernel message:
[drm] GMBUS [i915 gmbus vga] timed out, falling back to bit banging on pin 2
internal and external monitor stay dark. The machine only is accessible from outside. This even might happen before logging in.
00:02.0 VGA compatible controller: Intel Corporation Core Processor Integrated Graphics Controller (rev 18 )
02:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Madison [Mobility Radeon HD 5650/5750 / 6530M/6550M] |

problem can be solved by setting the boot parameter radeon.runpm=0
this deactivates the runtime powermanagement, which is activated by default in 3.13 |

| It would be good if you could notify upstream about it, as they depend on feedback to fine tune the quirks for different devices (I went through it with nouveau in 3.12). |

hi mijobe,
is the story going on ?
( i have the same story here: X1200 radeon )
Are there any news ?
Is the GPU now cooler or warmer ?
Why is "this hack" not "IN" the newest kernel built-in ?
? |
