Ati drivers frustration(Radeon HD) Help please[Solved]

Hey I've been having a few problems regarding the ati drivers in arch linux. I'm rally happy with the performance and quality of the free driver which I found WAY better than the proprietary driver except for one thing(which is driving me insane): The free driver does not regulate the video card's fan speed--at least--by default. Is there a way to make my fan hush up? The proprietary driver does a good job at this but I would prefer to continue to use the much better free driver.

Re: Ati drivers frustration(Radeon HD) Help please[Solved]

On the wiki page you gave me it gives me two choices:

1. Try adding radeon.dynpm=1 to the kernel parameters (if using the stock kernel < 2.6.35). If you are using kernel26>=2.6.35 this option is no longer needed and the sysfs interface will be present by default. If this option is passed to a kernel >= 2.6.35, the driver will fail and fall back to software rendering.
2. Use the (unsupported) [radeon] repo:

So I tried the first option first. Result: X wouldn't even start and it dropped me into console mode without even bringing me to kdm first.
After that I went and chaged grub back to the way it was before and X was able to load again.

So then I tried the second option. I added the radeon repo to the list and I also snuck a peak at it in my browser. Result: I got a 404 error from the repo.

Am I doing something wrong? Maybe just a stupid mistake?

Start from "Dynamic frequency switching (depending on GPU load)" headline.

Re: Ati drivers frustration(Radeon HD) Help please[Solved]

hello!!!
my english is very bad,but

test if power management is initialized
dmesg | grep drm | grep power

if it's ok then test this profiles

in root terminal

echo low > /sys/class/drm/card0/device/power_profile           

or

echo auto > /sys/class/drm/card0/device/power_profile

verify the gpu clock setting  with this command:
cat /sys/kernel/debug/dri/0/radeon_pm_info

for automatic boot one of this profiles ,put it in  /etc/rc.local

Hi! I checked both low and auto profiles and they are initialized. However my fans are still running loud (not the case on my windows partition).

from the wiki link in the second post:

"echo dynpm > /sys/class/drm/card0/device/power_method"

works, but in my case (hd5100) there is a tiny glitch (noticeable) every time it switches (i think)

the "auto" profile method only chooses based on the AC adapter state, but the "low" setting works for me

Fixed. Thanks for everyone's help!
