Guide to Get the Best Performace from the GMA 500

[bodhi.zazen]

Hi Bodhi
Is working well, enough snappy to be usable. In fedora seems a bit faster, probably because of the updated gma500_gfx module present in 3.3 kernel.

I'll add some notes in the wiki about llvmpipe

Great, I played with llvmpipe a bit in Ubuntu, was not the best of experiences to suggest to a new user.

llvmpipe has been in more rapid development (faster changes, improvements) then gma500_gfx (at least in the last few weeks on Fedora).

If you have problems with ubuntu,let me know, perhaps we can ask the fedora dev for advice.

I tried the 12.04 ubuntu desktop release iso on my acer ao751h, and letting it boot normal, the graphic display comes up filling half the screen.

The solution for this problem is still to switch to tty1, and do a service restart on lightdm.

Once the desktop came up, everything else looks good. wireless works, volume control works. brightness adjust buttons work however brightness doesn't appear to change.

Havent tried sleep or hibernate yet as it isn't installed yet.

Regards!

Agreed! I was just updating that the 12.04 released today has the same behavior as the beta 2. I was hoping the fix would make it into 'production'.

I did also see the behavior where even when the fix was installed in grub as outlined, that as mentioned earlier in this thread that some still need to switch to tty1, and then back to tty7.

I have the HP Slate 500 and it unfortunately has the GMA500

Now it worked find on the LiveCD, but when I reboot it has the black screen. Adding "console=tty1" does not fix the issue. I have not altered drivers from the default ones. Cnt-Alt-T plus the lightdm command works to fix it, but this is a slate, I don't have these buttons readily available. It does say Driver "unknown" in the "Details" menu

Any suggestions?

Hello there,

Well, I have 2 problems with Xubuntu 12.04 on my Vaio VPCX11S1E:

1) When I add console=tty1 I cannot login with my account anymore. It always recycles me back to the login screen. Creating a new user works and logging in with guest works as well. But then I dont have the admin rights.

2) The GMA500 works almost out-of-the-box, BUT the display flickers really bad. I had this with Bodhi Linux 1.4 and now with Xubunt 12.04. In addition, little black stripes are moving across the dislpay. I looks like the blue frame on http://www.xubuntu.org.
I am wondering if it could be the refreshrate. In Settings>Display it says refresh rate: 0.0 Hz.
I did not have this problem with JoliCloud. The screen looked perfect.

Does anyone has an idea?


EDIT:
The logging in Problem is solved. It seemed to be an issue in beta 2 and after updating to the finale release <it works fine. But there is still the blackscreen.

Editing the grub commandline to console=tty1 does not avoid the blackscree.
Switching back to tty7, looking like

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash console=tty7"

does not avoid the blackscreen either.

What can I do?

i did believe i would be able to install it from launchpad, but i just misread the wiki.
