Since you switched from Catalyst, maybe you should try to "clean" a little your config, like removing /etc/X11/xorg.conf.d/20-radeon thing, which I don't have in any computer. Just to prevent some conflict. Try not to pass any command to kernel and then retry to edit the pm files as root.

After removing catalyst, I deleted everything in xorg.conf.d and remade the files in there. Nothing in there is a remainder from catalyst. The 20-radeon file isn't necessary but it's for changing some of the default options on the driver. I also distinctly remember not being able to change similar settings files in /sys/class/... when running catalyst. Maybe there's something weird up with my graphics card?

Do you get something when you run this?

cat /sys/kernel/debug/dri/0/radeon_pm_info

Try this:

nano /sys/class/drm/card0/device/power_dpm_state

This is to help answer some questions before they come up too much.

It's just because of the way that cat works. Run the command as root and it will work just fine.

mesa-git will get many radeon cards up to OpenGL 3.3 and has significant performance improvements for Southern Islands up. mesa 10.1 will include much of this, but users of cards from Southern Islands up should probably stay with this repo. I've been using the repo for a long time and the mesa/kernel/radeon devs generally push stable code. kernel 3.14 is going to have a lot of performance enhancements for newer cards and hopefully fix and enable dpm for the Barts series of cards.

If you want to benchmark your card, you'll need to do a few things. First off, vsync is enabled by default, so your FPS will equal your monitor's refresh rate until it falls under it. So, disable vsync and use the performance setting for benchmarking. The info can be found in the wiki.

Wow, I'm out of it--yes, here's the output from running as root:

uvd    vclk: 0 dclk: 0
power level 0    sclk: 25000 mclk: 15000 vddc: 900 vddci: 950

I have an HD7770, which repo should I use? At the moment I am in stable, and with the 3.13 kernel my FPS went up a lot. I am willing to try mesa-git to see if it improves even more.

Is this the one we should use? Or do you think I should stay with stable?

Any suggestion for tearing?

There may be tearing fixes somewhere in the various git stack (mesa/xf86-video-ati), but I'm not sure. There is a suggesting in the wiki about enabling EXAVSync. I don't play games and haven't seen tearing anywhere, so I'm not a good resource.

The choice between going with mesa-git really depends on your needs. All of the drivers have gone through massive changes and the newest of cards are still getting a lot of performance enhancements. But if OpenCL is something that's important to you, the git branches is where all of the action is.

@joanmanel: I have the same GPU as you, and I can assure you it works perfectly

You can install those drivers and then remove the repo to be sure they're never updated (and possibly broken). Next week we'll see if Mesa 10.1 is good enough for gaming.

this is amazing! dota2 all maxed and the game runs perfect

I don't like the idea of having mesa-git, but oh well

amazing! much better than catalyst
