Re: No more OpenGL with ATI R300 after upgrading to Debian testing

[Christian Zigotzky <chzigotzky@xenosoft.de>]

Hi Gabriel,

Could you try the unofficial mesa versions for PowerPC, please?

Please look in the following threads:

I don't know if these versions could help you. We only use the 
unofficial Mesa versions for our AMD Radeon HD graphics cards on PPC Linux.

Rgds,

Christian
