Catalyst : Loud fans on a 6370M laptop even while using xvba acceleration

[xgt001]

also here are my readings during video playback and after video playback

 amdconfig --odgc

Default Adapter - AMD Radeon HD 6300M Series
                            Core (MHz)    Memory (MHz)
           Current Clocks :    750           800
             Current Peak :    750           800
  Configurable Peak Range : [400-750]     [500-800]
                 GPU load :    29%

fans ablaze louder than a jet engine.. a minute after stopping the video playback

 amdconfig --odgc

Default Adapter - AMD Radeon HD 6300M Series
                            Core (MHz)    Memory (MHz)
           Current Clocks :    157           200
             Current Peak :    750           800
  Configurable Peak Range : [400-750]     [500-800]
                 GPU load :    0%

so AMD wants me to use Windows DXVA acceleration just to play videos... NICE

yeah... looks like mostly that I am going to add myself to this bug report

Are you sure fglrx was installed correctly?
try:

lsmod | grep fglrx

EDIT: also try:

lsmod | grep radeon

it is installed properly

here is what I get...

ganesh@XGT-UbuntuLTS:~$ lsmod | grep fglrx
fglrx                5201162  184 
amd_iommu_v2           19199  1 fglrx
ganesh@XGT-UbuntuLTS:~$ lsmod | grep radeon

Well thats a bit high CPU temp. The fans are doing their job it seems.
Whats the output of

aticonfig --od-gettemp

Dont hold your breath on this one, it might give erroneous results (i have -5 C on my AMD Radeon HD 7560D/A8-5500 at ~21 C room temp). But maybe it will work given that you have a dedicated card.

PS. Laptops+Dedicated cards = always higher temperatures because the cooling system has to cope not only with the CPU but also with the dedicated card. The fan speeds are regulated by both mobo/CPU and GPU temperatures, so any of them overheat, the system will spin them up.

I get this message on trying

root@XGT-UbuntuLTS:~# aticonfig --od-gettemp
ERROR - Get temperature failed for the Default Adapter - AMD Radeon HD 6300M Series

also here is my top screenshot, while playing a 720p .mp4 file in mplayer-vaapi everything looks fine.. like I said in the question, the fan noise arises ONLY during video playback despite the low CPU usage :-/ I know really this is weird.. please give some pointers towards fixing this issue

Maybe you could try "messing" with the acpi_osi kernel parameter and see if it helps. I use acpi_osi="Linux" because the fans seemed to work more than needed and it seems much better afterward.
Can't guarantee it will be the solution of course.

Check temperatures (sensors).


and

GPU utilization.

aticonfig --adapter=0 --od-getclocks"

here are my values

amdconfig --odgc

  Configurable Peak Range : [400-750]     [500-800]
