Yeah !!!
With your xorg file it works.
Many thanks.

It's nice to see an Ubuntu with an standard Application menu :D

But it feels very laggy.
See this screenshot, even glxgears is very very slow.

Do you know if I miss an important package ?
Thx again ;)

Did you install the unofficial Mesa? Please post the output of the following command:

Code: Select all

glxinfo | grep -i opengl

No, i don't think that I installed anything (except mesa-utils to run glxgears)

I just realize too that I don't have copied the kernel files in /lib/modules.
I will post the glxgears output tomorrow and install your latest vmlinux-3.19.0-rc7.

Is this mesa-unofficial is downloadable from somewhere, please ?

Before to installing Mesa...

glxinfo | grep -i opengl

Installing Mesa...
you made a little mistake in your procedure.
You added a uppercase to LibGL.so.1.2.0
"sudo cp mesa-10.0.4/lib/LibGL.so.1.2.0 /usr/lib/powerpc-linux-gnu/mesa"

rebooting...
mesa looks fine now

You get the same as your monitor refresh rate (60Hz = 56-60fps). You simply need to override the variable vblank_mode to not run synchronized to the vertical refresh.

Code: Select all

vblank_mode=0 glxgears
