Hey folks,
I've been running into a massive problem with power saving with the radeon driver and my HD 5770. I want to report this bug but wanted to check these forums for input first.
I'm running ArchLinux and the problem is the same with Linux 3.4, 3.5 and 3.6-rc3.
When plugging in my second monitor (it doesn't even need to display anything and can be turned of in the display settings) my video card fan goes crazy and the card heats up extremely fast.
I've been using the power saving method mentioned here: https://wiki.archlinux.org/index.php...th_KMS_enabled with profile set to low for a while and it has been working great.
However when the second monitor is plugged in the card doesn't down clock at all, I've this output from debugfs:
with both monitors:
directly after unplugging:
Is this a known problem or should I report it?
