iBookg4 800Mhz 3D Hardware Acceleration

Asked by RobertoBenzi

Hi there, I'm new to Linux and I'm trying to get it work.
I have installed Lubuntu 12.04 on an iBookG4 800Mhz (PowerPC) and I'm not being able to enable 3D Hardware Acceleration, the glxinfo says

I've tryed doing what is said in Ubuntu PowerPC Known Issues ( https://wiki.edubuntu.org/PowerPCKnownIssues )

No userspace mode setting 3d hardware acceleration

In 12.04 there is nolonger mesa support for Mach64 and Rage 128 cards or user-space mode setting (non-KMS) with radeon cards. See bug.

To solve this you need to install an older version of mesa*. Download the following PowerPC deb packages

libgl1-mesa-dri_7.11-0ubuntu3_powerpc.deb
libgl1-mesa-glx_7.11-0ubuntu3_powerpc.deb
libglapi-mesa_7.11-0ubuntu3_powerpc.deb
libglu1-mesa_7.11-0ubuntu3_powerpc.deb

from launchpad or directly downloading from the ubuntu ports repository.

Save them together in a directory. From a terminal 'cd' into that directory and then issue the command

dpkg -i *.deb

to install all the deb packages together.

You'll now need to 'pin' the version so that they are not updated when you next use the Update Manager. The easiest way to do this is through the Synaptic Package Manager. Select the libgl1-mesa-dri, libgl1-mesa-glx, libglapi-mesa, and libglu1-mesa packages in Synaptic and then in the menu goto Package > Lock Version.

Finally, if you have a radeon card then edit your yaboot.conf file to add the radeon.modeset=0 yaboot parameter.

See the PowerPC FAQ for how to optimize your xorg.conf file.

* r128 users can alternatively compile and install the mesa-legacy package.

But then upon launching glxinfo and glxgears i get the following errors

[QUOTE]
roberto@iBookG4:~$ glxgears
Error: couldn't get an RGB, Double-buffered visual
roberto@iBookG4:~$ glxinfo
name of display: :0
Error: couldn't find RGB GLX visual or fbconfig
[/QUOTE]

How can I make it work?
The Video Card is a ATI Mobility Radeon 9200
Please speak as simply as possible 'cause I'm a total Linux newbie

Thanking you in advance,
Roberto
