GMA500 (Poulsbo) gma500_gfx

[bodhi.zazen]

I wanted to report the state of my Sony Vaio P series VGN-P788K. I tested with a 12.04 32-bit install with all updates as of 2012-05-28 applied. The kernels used were 3.2.0-24 from precise and 3.4.0-3 from quantal.

Graphics

• 3.2: Boots to black screen. Switching to another tty then back to tty7 brings up graphics. They are always broken; only the upper half of the screen is used.
• 3.2 with console=tty1: Switching to another tty then back to tty7 brings up graphics. They are usually correct, but sometimes only the left two-thirds of the screen is used.
• 3.4: Switching to another tty then back to tty7 brings up graphics. They are always correct.
• 3.4 with console=tty1: No different than 3.4 without this option.

Suspend and Resume

• 3.2: Suspend and resume work out of the box.
• 3.4: Suspend does not work. Although the screen goes blank, the laptop never suspends. I tried all the possible quirk options to pm-suspend but none changed this behavior.

You probably want to file bug reports on that behavior. I can not repeat you black screen / distortion problem and the suspend issues sounds like a regression.

The first problem can be beaten with some workarounds like disabling plymouth and changing the resolution in grub and i915-connected files.

The second is a regression, I have the same problem, wrote about it in my previous post... Someone can post a bug at kernel.org as i don't feel like i understand how to do this and i have the skills

Remove "splash" from boot options, for me that helped on 3.2.0 and 3.3.5.

I also have an Acer A0751h and the boot options bodhi.zazen suggested worked great. However, I have some questions regarding performance.

I can't watch videos online because sometimes the video and sound get out of sync, the video freezes, and things like that.
Are you able to watch videos? If so, what other configurations changes have you made?

Have you tried programming on this computer?

I'm just trying to get the best performance possible because even Gmail takes a little to long to load...

Thanks

Watching online video (in browser) doesn't work very well in 12.04. In fact, anything related to multimedia or to rendering heavy web content would greatly benefit from hardware acceleration, which the combination of gma500 and psb_gfx lacks completely.
Programming shouldn't pose a performance problem, unless you'll be compiling something the size of the Linux kernel. It's mostly just plain text, and if you are happy with the screen real estate, by all means, try it.

Hallo,

can the GMA500_gfx module control multi displays with different resolutions?

[thermatk]

mozphere,mikewhatever,
Videos from Youtube are working on 360p and more with flashvideoreplacer and mplayer
with flash it's crap
and without mplayer it's buggy
should I explain this easy modifications?

Just loaded the latest Ubuntu 12.04 to my late model Sony Vaio P-Series microlaptop (VPCP11SKX) which has the Intel GMA500 onboard graphics. When I trialed the OS from the USB stick, it booted up well and everything seemed to work. On installing, the problem is the screen.

At first, it booted up to a black screen after intially showing the splash screen. By pressing F1 during boot, it would then randomly boot to different screen sizes or to the correct screen resolution ( 1600x768 ) but using only half the screen.

I figured out that by logging out and logging in when only half the screen resolution came up that it would come out using the whole screen, as in the trial.

When I look at system details, it tells me the Graphics are "unknown"

How do I load the gma500 driver and will that fix my screen problem

Did you not read the first post ?

See : https://wiki.ubuntu.com/HardwareSupp...eoCardsPoulsbo

Is there some step on the wiki page you did not understand ?

I know this is a little off topic but....Thank you Alan Cox for developing this driver!
