Question Slow graphics with Slackware 13.37 and Radeon Mobility X1600

Hi,

I've upgraded (reinstalled) from Slackware 13.1 to 13.37 on an old iMac and have problems with slow graphics.
lspci says this about the graphics card:

Code:
01:00.0 VGA compatible controller: ATI Technologies Inc M56P [Radeon Mobility X1600]
With Slackware 13.1 I had no KMS enabled and graphics speed was okay. It wasn't very good, but okay for everyday work. Now with 13.37 it's extremely slow. glxgears runs with only around 38 fps, no matter what I do. And every now and then when logging off, I get a black screen and no new kdm-login. But I can ssh into that machine and restart X by issuing 'init 3;init 4'.

KMS is enabled (I've also tried disabling it, but then KDE crashes right after logging in) and it's a fresh installation of 13.37 with a 2.6.37.6 kernel.

What can I do?

I have to admin I don't know this video and X stuff very well and I used to have machines with NVIDIA cards, so these Radeon problems are completely new to me.

If there's anything else than the usual Xorg.0.log needed, please tell me.

To me the log doesn't look like there's any problem whatsoever:

Hi, I'm not an expert of video cards, but I've an ATI Radeon Mobility X1400 and I've experienced your same issues.

I'm using the KMS (Kernel 2.6.37.6-generic-smp) and the radeon driver. Here the "glxinfo" output:
Code:
...
name of display: :0
display: :0  screen: 0
direct rendering: Yes
server glx vendor string: SGI
server glx version string: 1.4
.....
OpenGL vendor string: X.Org R300 Project
OpenGL renderer string: Gallium 0.4 on RV515
OpenGL version string: 2.1 Mesa 7.9.2
OpenGL shading language version string: 1.20
Here, glxgears runs with around 59 fps.

I'm partially solved disabling the KDE Desktop Effects and removing the Oxygen Window Decoration animations!

Same issue here. It seems solved by disabling the KDE Desktop Effects.

Just out of curiosity, two days ago I installed "compiz" (by slackbuilds.org) in order to have the desktop effects again.
I could notice that compiz is much more lightweight then the "native" KDE desktop effects (at least for my computer!) and now I can successfully work in KDE with the KMS and the compiz desktop effects!

I suppose that you have to downgrade to the "mesa-7.8.2-i486-1.txz" and to the "xf86-video-ati-6.13.2-i486-1.txz"
in order to successfully launch KDE with the KMS disabled (by appending the "nomodeset" option)
You can find these packages in /pasture.

glxinfo gives me the same output, exact that mine is a RV530, instead of a RV515.

Disabling desktop effects is real eye-opener how fast KDE can be. Thanks for the tip, now the machine is usable again, although I'm missing the eyecandy. Perhaps I will try out compiz, once I have some spare time and feel adventurous enough. But effects are not what's worrying me. I fear Google Earth won't run properly anymore (glxgears doesn't either), but I haven't tried out, yet.

And I hope you are right, logging off will not be an issue anymore. Time will tell...


I'm still curious, though, what the real reason of the slow graphics performance is. Is it a driver issue or could it be solved with configuration changes?

What role do mesa and libdrm play? I'm asking this because there are newer versions in 'testing'. Has anyone tried these out or would that be useless?

Same here. glxgears is just about 59 fps. And X gets pretty high cpu if mplayer uses "vo=gl".

Same problem. I have a radeon X300SE that worked fine out the box on 13.1 after I ran xorgconfig and enabled dri. Now with 13.37 my graphics performance blows. glxgears is running at 16fsp! Why the regression? What happened to xorgconfig?

Thanks

I have a ATI Radeon Mobility 9600 and I get around 59 fps as well... I finally had to turn off KDE effects.

glxgears is in no way a reliable benchmark. And to all those that get nearly 60 FPS in glxgears, the chance is very very high that you run it with vsync enabled. This way you will never get a different FPS value than your monitors vertical frequency, with LC-Displays most likely 60 Hz.
