Re: No direct rendering

My graphics rendering is really slow.

Maybe this is problem:

OpenGL vendor string: Mesa project: www.mesa3d.org

Have you tried this:
Ubuntu Dapper Installation Guide
http://wiki.cchtml.com/index.php/Ubu...allation_Guide

In Ubuntu Dapper you can choose between two methods of installing the proprietary ATI driver. If you are new to linux you should use the first method as it is a lot easier than the second one and will work well in most cases. The second method describes how to install the very latest driver version, but requires some additional work and knowledge.

Useful information:

KubuntuDapperKnownProblems
https://wiki.kubuntu.org/KubuntuDapperKnownProblems

Using fglrx or ati drivers may cause KDM/xorg to freeze on logout or reboot [WWW] #30447
Workaround: add (uncomment) the line TerminateServer=true to section [X-:*-Core] in /etc/kde3/kdm/kdmrc

Checking driver:

Code:

:~$ fglrxinfo
display: :0.0 screen: 0
OpenGL vendor string: ATI Technologies Inc.
OpenGL renderer string: RADEON 9600 XT Generic
OpenGL version string: 2.0.5814 (8.25.18)

Testing:

Code:

Code:

:~$ fgl_glxgears
Using GLX_SGIX_pbuffer
2972 frames in 5.0 seconds = 594.400 FPS
4546 frames in 5.0 seconds = 909.200 FPS
4534 frames in 5.0 seconds = 906.800 FPS
4545 frames in 5.0 seconds = 909.000 FPS

Code:

:~$ glxgears -printfps
23436 frames in 5.0 seconds = 4687.105 FPS
23337 frames in 5.0 seconds = 4667.340 FPS
23321 frames in 5.0 seconds = 4664.134 FPS
23303 frames in 5.0 seconds = 4660.479 FPS

Re: No direct rendering

Hi,

I followed the links you provided but couldn't find a solution. I applied both

Ubuntu Dapper Installation Guide
http://wiki.cchtml.com/index.php/Ubu...allation_Guide

and Howto: Fglrx 8.26.18 & 8.27.10 Driver Install (works With Xpress Series Cards Now!)
http://www.ubuntuforums.org/showthread.php?t=204910

without results.

Here's some info:

Code:

:~$ fglrxinfo
Xlib: extension "XFree86-DRI" missing on display ":0.0".
display: :0.0 screen: 0
OpenGL vendor string: Mesa project: [url]www.mesa3d.org[/url]
OpenGL renderer string: Mesa GLX Indirect
OpenGL version string: 1.2 (1.5 Mesa 6.4.1)

I cannot run fgl_glxgears:

Code:

:~$ fgl_glxgears
Using GLX_SGIX_pbuffer
Xlib: extension "XFree86-DRI" missing on display ":0.0".
X Error of failed request: BadMatch (invalid parameter attributes)
 Major opcode of failed request: 154 (GLX)
 Minor opcode of failed request: 5 (X_GLXMakeCurrent)
 Serial number of failed request: 30
 Current serial number in output stream: 30

Code:

:~$ glxgears -printfps
Xlib: extension "XFree86-DRI" missing on display ":0.0".
643 frames in 5.2 seconds = 124.508 FPS
456 frames in 6.1 seconds = 75.254 FPS

I have fglrx driver version 8.27.10 installed but dmesg says following:

Code:

:~$ dmesg | grep fglr
[17179606.816000] fglrx: module license 'Proprietary. (C) 2002 - ATI Technologies, Starnberg, GERMANY' taints kernel.

[17179606.820000] [fglrx] module loaded - fglrx 8.25.18 [May 18 2006] on minor 0

Any ideas?

Re: No direct rendering

In addition, atieventsd process consumes about 50% of CPU usage. What can I do with that?

Re: No direct rendering

Hmm - Did LIBGL_DEBUG=verbose glxinfo display missing files ?
(from Troubleshooting for both Methods)

Something to try (just quessing :P ):

1) Comment xinerama off from xorg.conf
Why ?

From HowTo: Dual Monitors (Xinerama/TwinView/MergedFB)
http://www.ubuntuforums.org/showthread.php?t=221174

Xinerama (first HowTo) does not allow DRI, so if you want to have DRI enabled, then please try the second or third HowTo.

I have tried Big-Desktop - seems to work with fglrx. I haven't tried xinerama.

Big Desktop is the binary function of MergedFB. Big Desktop enables features similar to Xinerama with the addition of 3D Acceleration Support.

2) Try to reinstall xserver-xorg-core
dexter did have same kind of problem with Ati 9800 SE.

Topic: Ati 9800 SE 3D
http://kubuntuforums.net/forums/index.php?topic=7951

Strangest thing just happened downloaded the xorg core update which screwed up the system downgraded the xorg core and guess what I HAVE 3D WORKING

display: :0.0 screen: 0
OpenGL vendor string: ATI Technologies Inc.
OpenGL renderer string: RADEON 9800 SE Generic
OpenGL version string: 2.0.5946 (8.27.10)

then upgraded to the fixed core and its still working YIPPEEE

So you could try reinstallation (xorg core).

Re: No direct rendering [SOLVED]

Back to business, I had to do some "work" for a while...

It's working now. I started configuring from beginning as suggested in #1. Thanks! I even have dual head working now.

Re: No direct rendering [SOLVED]

glxgears -printfps

So THAT's the command to get fps on kubuntu computers!

Just posted this to my local LUG. Man, it's all in the details

Thank you

Wishing you well.
