[kubuntu] Hardy - ATI Radeon 9550 Direct Rendering works, but no 3D

linux-howto

http://ubuntuforums.org – I was running Dapper with both direct rendering and 3D acceleration working using the fglrx binary driver for my ATI Radeon 9550 card. I recently updated to Hardy, and switched to the free software radeon driver. After doing some research and tweaking, I managed to get direct rendering working. glxgears now shows decent frame rates (e.g. 1757.013 FPS). However, none of my 3D apps seem to be accelerated (KDE screen savers like "Solar Winds", nexuiz). Does anyone have any idea what the problem is or what I could try? Thanks! (Hardware)

No Direct Rendering 3 years 11 weeks ago

I typed this in the console using both user and root permissions: glxinfo | grep -i direct and it says for both: *** WARNING: Direct Rendering is NOT enabled

I have successfully installed the 10.2 proprietary driver from ATI. But how do i enable Direct Rendering?

Thanks in advance

Unichrome and OpenSuse 11.2 3 years 24 weeks ago

Before OpenSuse 11.2 I used some Debian-based distros that used to have a good support for my integrated video card Via Unichrome P4M800 Pro / CN700. I had 3D running with direct rendering by Mesa. With OpenSuse I'm having problems to configure my graphics with a good configuration...

I want to enable desktop effects (normal or extra) but I get the message:

Desktop effects could not be enabled.

I have a ATI Radeon HD3200 graphics card. I've seen in other posts that this has to do with the driver 'fglrx'. But when I do:

dmesg|grep 'fglrx'

I have a quite old laptop with a S3 Twister K which correspond to a ProSavage KN133 so the savage driver gets used. This chip is far from a powerhouse, but it can move enough textured polygons to run even UT2003 with decent speed (back then when the first demo got released on windows).

My Sapphire Radeon HD5450 graphics card works great with 2D graphics, but I can't seem to get hardware 3D acceleration working properly on an up-to-date Debian Squeeze running on the amd64 architecture.

glxinfo reports:

direct rendering: Yes server glx vendor string: SGI server glx version string: 1.2 ... client glx vendor string: Mesa Project and SGI client glx version string: 1.4

while lspci

Here a new fresh openSUSE 11.3 installed where everything works like a charm :) The only worry I have now is about the default free radeon drivers (r600) where they seems to be working well but clearly it's not same as my past openSUSE 11.2 with fglrx.

Fedora 12 + nVidia + Compiz 3 years 24 weeks ago

Hi, i'm unable to get Compiz working.

I've already uninstalled nouveau, put "rdblacklist=nouveau", and blacklisted it. I've also installed nVidia, and configured it to work with my dual head setup. everything works great, except when i try to enable Compiz:

Code:

  1.       $ compiz --replace   2.

ah, thank you for answering!it was tearing, the word i didn't remember.uname -r 3.2.0-4-amd64glxinfo | grep "direct rendering" direct rendering: Yesanyhow i was playing around and noticed that the tearing is (almost 100%) gone when i disable compton.but, following your links, ->running a dist-upgrade now. finished.yeah, that fixed it.wow. and thanks. again.

Desktop Effects could not be enabled. Also, I'm not having any luck installing Catalyst drivers. After installing Catalyst driver for the right kernel version, Xorg goes corrupt when starting up.
