Some Help please (Trying FOSS over Catalyst)

[ForkedPython]

If you come back to the FOSS drivers before the 13.10 release, there are two things to do to have the latest versions of everything:

Adding the Xorg Edgers PPA for up-to-date Xorg and Mesa with

sudo apt-add-repository ppa:xorg-edgers/ppa

And grabbing official 3.11 RC kernel packages here:

[url]http://kernel.ubuntu.com/~kernel-ppa/mainline/[/url]

You'll need -image, -headers and -headers-common. I don't know if the RC are problem-free, but we're getting close to the 3.11 release so there are good chances they are.


Then with DPM and the R600_DEBUG=sb optimizations enabled you should get good performance in games.

LOL im back already! Catalyst is just crap on cinnamon, i ended up with stutter that would occur when moving windows . playing games ... anything! every 1 second for a few milliseconds.

Am I on a good version ?

my driver says: xserver-xorg-video-ati : Version 1:7.1.9git20130730.6a278690-0ubuntu-sarvatt~raring

I did a sudo apt-add-repository ppa:xorg-edgers/ppa

my Power meter still reads about 15-20w higher than with catalyst?

now is there a clean and easy way to upgrade to 3.11 kernal and get the DRM and power benefits?

Welcome back

The current 3.11 RC is here:

http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.11-rc5-saucy/

They're the official Ubuntu kernels, so this is the cleanest it can get.

Then to enable DPM you need to add radeon.dpm to the GRUB command line with:

gksudo gedit /etc/default/grub

You should see GRUB_CMDLINE_LINUX_DEFAULT="quiet splash", change it to

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash radeon.dpm=1"

Then update the GRUB files with:

sudo update-grub

Don't reboot yet, you should also enable the SB optimizations desktop-wide:

gedit ~/.profile

Add the line

export R600_DEBUG=sb

And then after rebooting check in dmesg that DPM is enabled.

Thanks for the help. I shall do this right away and check the performance. Im officially done with official

snips

typing dmesg:

1.322542] [drm] radeon: dpm initialized

Kernel command line: BOOT_IMAGE=/boot/vmlinuz-3.11.0-031100rc5-generic

my driver is as mentioned: 1:7.1.9git20130730.6a278690-0ubuntu-sarvatt~raring

So thats latest Kernal + FOSS driver i think i should be good


But i have the same problem as Catalyst???


on a side scrolling game i get a micro stutter at a same timed interval -> then plays for 2 seconds then a judder then 2 seconds and then a judder.. like a load pause? I get this when moving a window across the screen (but its harder to see because of general tearing and the time needed to get across from the screen)

I get this with catalyst in all states apart from with forced vsync / tear free (but that brings into play a lot of lag)

Seemingly then both the catalyst and FOSS are broken for me, what to do ?

Sorry I may have forgotten a step, you need newer firmware from:

https://launchpad.net/ubuntu/saucy/+package/linux-firmware

Also the rc6 was released:

http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.11-rc6-saucy/

Those micro stutters with fglrx were the reason I switched too: http://phoronix.com/forums/showthrea...ht=#post330329

They disappeared completely on my Evergreen laptop. Which game is it btw? Maybe you could try to disable desktop compositing (on KDE it's Ctrl + Alt + F12) before running a game, see if that makes the stuttering disappear

It'd be neat if someone who got the FOSS drivers working with Southern Islands could check if I didn't miss anything.
