Description Julio Garay 2009-11-17 00:01:08 UTC

I'm using a Sapphire Radeon HD 4550. It is connected to a Sony TV through the HDMI connector. Resolution and colors are OK, but it works painfully slow (I mean I can even tell the steps of the transitions between different backgrounds in Gnome, for instance).

I have tried all driver options I found through Internet, like:

 Option      "AccelMethod" "exa"           # [<str>]
 Option      "DRI" "on"                     # [<bool>]
 Option      "Audio" "on"                   # [<bool>]
 Option      "HDMI" "all"                   # [<str>]
 Identifier  "Card0"
 Driver      "radeonhd"
 VendorName  "ATI Technologies Inc"
 BoardName   "RV710 [Radeon HD 4550]"
 BusID       "PCI:1:0:0"

(By the way, I'm getting no audio through the HDMI connector either).

I have found the same speed problem with the ati driver.
I'm using Archlinux, completely updated.

radeonhd doesn't support KMS.

Try again without KMS being enabled by default.

Well, this SOLVED my problem, indeed. I tried to reboot adding "radeon.modeset=0" to the boot line, and it worked like a charm.

To make it permanent, I created a file named /etc/modprobe.d/radeon.conf and wrote into it the following line:

options radeon modeset=0

After rebooting, it seems to be behaving perfectly. I guess this won't be required after KMS is supported for these cards too.

By the way, all the solution lines I used are coming from the wiki.archlinux.org. I added there what I have learned here as well.

Thanks for all! I will open another bug for the audio problem.

I guess this bug can be closed now?

Kind regards!

KMS is supported for all cards (r1xx-r7xx), you just need a new enough version of xf86-video-ati.  radeonhd does not support kms at the moment.
