Re: [opensuse] Video Regression from 11.1 to 12.3 with Radeon 7000

I've done a great deal of searching & I can't seem to find a useful solution.

I finally got around to getting my old 11.1 install running on my
Thinkpad A30p with Radeon Mobility 7000. With 12.3, The video
performance is slow, and I can't get MPlayer to play a video at all.
With 11.1, I can play an x264 480p video with no problem. The laptop
has a Tualatin P3/1.2Ghz & 1GB RAM.

I've found all kinds of suggestions, like turning off KMS or creating
an xorg.conf file and changing accelmethod from EXA to XXA. Turning
off DRI made no differnce.

Nothing works. There seems to be a similar regression with uBuntu
from 8.10 to 9.04 as well.

I tried to copy the xorg.conf from 11.1 to 12.3 but it fails to load.

Understandable. SaX2 configured video for 11.1. SaX2 didn't exist in 12.3. Automagic is supposed to do 12.3 for most hardware and users.

Everything in it unrelated to video would need to be deleted for an 11.1 file to have a decent chance of being useful in 12.3. What does Xorg.0.conf look like when X has been run without any configuration done via /etc/X11/xorg.conf*? Is it actually using the radeon driver, or rather vesa or fbdev (aka SLOW)?

Has anyone managed to get this video chip working properly with newer
versions of oS?

No, but...

I have Radeon 7500 in 2 systems, and Radeon 9000 in one, all with moderately to significantly faster CPUs than yours, one with all openSUSE versions 10.0-up, the others with at least 11.4 all the way up through 13.2. I'm not very demanding of video except on any that are actually recommended as suitable for h.264 MPEG4 HDTV playback and editing. For all I have manually disabled compositing via /etc/X11/xorg.conf.d/50-extensions.conf thus:

Section "Extensions"
Option "Composite" "Disable"

All three use the automagically selected (radeon) driver. I can't recall any noticeable variation in, or lack of, acceptable speed according to which OS is booted, but as these are test systems, they do not get a lot of use in general, and even less trying to play video.

My oldest, slowest system, a 600MHz Dell laptop with r128 video (last generation ATI before Radeon 7000 introduction), seems to have retired itself via expired CMOS battery since 12.3 was installed on it last February. I remember its 1400x1050 video was at least tolerable considering the lack of CPU speed and only 384MB RAM.
