Guide to Get the Best Performace from the GMA 500

[nekr0z]

Ok, I see what you mean. In kde you get the notification as a kind of volume bar in the middle of the screen, and they work well without that kernel entry. Have you tried if the notifications work if you have eee-control but not the grub entry?

Sure, doesn't help.

Well, I installed a fresh copy of Lucid today and then the psb drivers from the GMA 500 ppa. Works fine . Then I thought about trying KDE too, but I had the problem reported above, system freeze during KDE splash screen (never loads).
Jbernardo since you mention it works for u, could I be doing something wrong? My xorg.conf is that minimal

Hi,
As promised here is my xorg.conf. I hope it helps, in that case we'll have to see which entries exactly help here.

Hi,
As promised here is my xorg.conf. I hope it helps, in that case we'll have to see which entries exactly help here.

Thank you, but I can't figure out what's going wrong here...The problem persists in exactly the same way .

What I've done so far is:
Purged, then reinstalled the drivers from
http://ppa.launchpad.net/gma500/ppa/ubuntu
I've installed kde-desktop-normal meta-package over ubuntu, I also tried to log in using KDM instead of GDM (don't know if that could ever make a difference though, just in case). The result was always a frozen KDE splash screen.

Have you installed Kubuntu in the first place? I can't think of any other difference.

There is a problem. At first you should change

Option "ShadowFB" "true"

to

#Option "ShadowFB" "true"

.

After that you are to switch composition from OpenGL to XRandr by JBernardo method (System Config->Desktop->Screen Effects advanced tab).

After that you can change again

#Option "ShadowFB" "true"

to

Option "ShadowFB" "true"

in your xorg.conf.

[jbernardo]

Thanks Napitok - I was already looking into .kde to see if gl composition was enabled by default and could be disabled...

[simplygades]

Thank you both!
I could not imagine that OpenGL was activated by default. Now it loads normally, however it does not allow Compositing, I just turned Desktop Effects completely off to proceed. Is some transparency possible, or is that a known problem?

You should have compositing, if you enabled XRender. Probably you just disabled everything, it is very easy to happen with the system settings in kubuntu. Go back to it, go to the last tab, check XRender is selected and apply.

[simplygades]

I had to deselect the "Compatibility check" box to let me have Desktop Effects enabled with XRender. Finally everything seems OK! Thanks Jbernardo and Napitok for helping me out with this!

Asus EeePC T91.
Installed driver. 1024x600, all seems to be ok but... Random Freezes still happen!! like in 9.10.

Who don't have random freezes? How did you fix it?

[alfrenovsky]

In a dell mini 1010

I had to boot with "acpi_backlight=vendor" to enable brightness control.
Now I have brightness from 0 to 7. But 7 (the max) is a little darker than without control.
When I boot I have full brightness, and if I set brightness to 7 I can see the light to go a little down, and I cannot get back to 100% without booting.

Any clue?
