Hello!
Sorry for my bad english, I'm russian:)
I have problem with AMD Catalyst 12.6 Legacy driver (from official site). I
installed this driver in Ubuntu 12.04 according to instruction from
help.ubuntu.com (I created deb packeges). Driver was installed successfully:
~$ fglrxinfo
display: :0.0 screen: 0
OpenGL vendor string: Advanced Micro Devices, Inc.
OpenGL renderer string: ATI Radeon HD 3200 Graphics
OpenGL version string: 3.3.11653 Compatibility Profile Context
Fan begins to change speed from fast to slow good.
But Unity after install this driver works slow, frozen, with artefacts.
With opensource driver ati (installed by defaults) system works faster,
smoothly and without artefacts. But fan speed changes very little and laptop
heats.
Later I tried to install this driver in Ubuntu 12.10 with ppa:makson-96/fglrx.
It was installed good, but I still have the same problem.
I tried to turn off 'synch to vblan' in CompizConfigSettingManager, but it
didn't help.
I tried to use open sourse driver and command from
www.x.org/wiki/RadeonFeature#KMS_Power_Management_Options (sorry, I don't know
how to do links:)). But it doesn't work for me. "cat
/sys/class/drm/card0/device/power_profile" displays "low" or "mid", but fan
speed changes very little (I can't compare temperature before commands and
after, because "sensors" doesn't display temperature of GPU - only CPU and HDD).
O, yeh, I installed Kubuntu 12.04 and Xubuntu 12.04 and these distrs work very
good with Catalyst legacy, quietly and without frozen. I have problems only
with standart Ubuntu with Unity.
Please, tell me what should I do to solve this problem?
