Description Vavooon 2011-06-08 22:34:29 UTC
It is installed Radeon HD6250M videocard in my netbook Acer Aspire One 522. I using Arch linux with xf86-video-ati drivers in KMS mode. Any versions of it, which i installed (packages from [extra], [testing] and Parry3D`s [radeon]) doesnt regulate voltage and frequency of GPU so my netbook is very hot (approx. 70°C).

Please see the power management section of this page:

I`m sorry: it`s my mistake that i has not check temperatures in Windows before installing Linux. They are normal.

P.S. Are there any power (voltage and frequency) settings that isn`t described here: https://wiki.archlinux.org/index.php/ATI#With_KMS_enabled ?
Do i can see current voltages or assign frequency of GPU/MEM in manual way?
Thank you.

Not at the moment.

I installed Catalyst driver on Arch after our conversation and noticed that temperature of my GPU was 20°C lesser (it was approximately 50-60°C instead of 70-80°C (depends on system load)). So i re-opened this ticket. Also i want to say that there is no GPU/MEM freq scalling in my VC (because all monitoring software in Windows and Linux shows permanant values), but Catalyst CC have an option with customizing perfomance of card.
