Problem installing Lubuntu 14.10

[zzd10h]

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

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

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

My pleasure. It's nice to see Xubuntu.

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

Code: Select all

glxinfo | grep -i opengl

[zzd10h]

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

BUT still a bad glxgears :

293 frames in 5.0 seconds = 58.377 FPS

Thank you for the hint. I have fixed it recently.

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

[zzd10h]

Ah yes, it's better

4399 frames in 5.0 seconds = 879.316 FPS
4232 frames in 5.0 seconds = 846.215 FPS
4753 frames in 5.0 seconds = 950.080 FPS
4728 frames in 5.0 seconds = 945.518 FPS


Thank you !

My pleasure! Just for info: I use your zTools. You're doing a great job!

[zzd10h]

My pleasure too

edit : oops, I made something wrong during installation.
It seems that I installed the 13.10 version. Because of the old initrd ???
