Guide to Get the Best Performace from the GMA 500

[Udibuntu]

The sound problem appears to be pulse related - I am not seeing it, but i am using kubuntu, so don't have to put up with pulseaudio.

As for mplayer-vaapi, did you try it on films with subtitles? I have it working perfectly except for that, *** subtitles don't show up, and non-*** kills mplayer with error 11 (mostly at the first subtitle).

No subtitles yet, I'm only watching WMV-HD clips from Microsoft (oh, the irony). I'll download some MKV's if the external VGA to HDTV connection works well.

BUT - I do get an error like this: "Too many video packets are in the buffer"; maybe b\c of my 1G RAM?

Off topic: sound problem is indeed pulse related; it usually comes and goes, and if is persisting then I purge and re-install the driver (hope a fix will be available soon.

Hi All,

Just a note...
After following some of the howto's here (Karmic 2.6.31-17-generic, UNR running on a T91MT - not T91) and installing evtouch source patches to get the T91MT touch screen working - I too have fast video. However, in UNR all apps are full-screened so I only had 500+ with glxgears UNTIL I restored the smaller sized window for glxgears. When doing so, I now get 1200+

I am getting lock-ups, tho I think related to touch-screen. Does it a lot in Xournal. So I am still working on other stuff - touch screen right-click (no stylus button) and I had the sound issue once.

EDIT: Forgot to mention I'm on an Asus T91MT - of course.
Also, the stuff I did that seemed to work was:

1. Speedster's post #201 and
2. this wiki post

I am getting 1200+ on 9.10 - but an ASUS T91MT, not Acer.

Are there any news on Poulsbo for Lucid?

And is anybody already packaging for 32 or 33 kernels?

[egrep]

One of my systems just updated to kernel 2.6.31-17. I remembered to rename the xorg.conf file before rebooting so I came up in the standard video mode for the poulsbo chipset. I tried to re-apply the sudo wget http://gma500re.altervista.org/scripts/poulsbo_ppa.sh && sh ./poulsbo_ppa.sh script. Every time it gets to any kernel stuff, it skips that part with a "no module source" error.

Not sure if I am missing something or maybe the poulsbo fix has not been updated for the 2.6.31-17 kernel.

I will poke around and report back with what I find out.

Rather than rename xorg.conf when I installed the -17 kernel I did as the wiki said - rebooted into recovery mode and ran

dpkg-reconfigure psb-kernel-source

which recompiled the module for the new kernel.

Hi all!
I'm trying out Intel IEGD 10.2 driver for GMA500 following this guide:
FitPc2 howto

Pros:
* Native resolution (1366x768 )
* UXA Hw acceleration
* 2100 fps in 5secs using glxgears (using old psb drivers i get 1250fps)
* Low memory footprint
* Smooth flashplayer (sd)
* Mplayer-vaapi (support for hd movies)

Cons:
* No DKMS
* Slow firefox scrolling
* Broken framebuffer (no usplash - moblin-dev mailing list bug)
* Some visual glitches (uxa related maybe)
* Broken hibernate/suspend (iegd 10.2 bug)

Feature/compatibility list for IEGD 10.2 drivers here
User's guide here
Specification update here


Anyone else tried it?? Just curious!

PS. To make it work i've modified some options in xorg.conf (details on request)

Hi All,

Wanted to share my experience in a related issue, in case someone wants to investigate this:

I'm with psb driver, GMA500 on an Acer751, Karmic.

I botched an attempt to use dual screen via VGA, and had to use xrandr to try and fix. I got numerous psb related errors while installing the GUI fronts for xrander, and couldn't change any xrander setting (in either GUI and terminal), other than adding new display modes that could not be set to operate.

I then purged and removed psb and re-installed Luca's FTP script (thanks again Luca), and all is well so far (hadn't tried to use the VGA port again yet).

I guess there is some kind of a problem in the combination of the current Linux psb driver and xrandr.

Re Luca's latest post: I would love to have decent Youtube experience, and therefor would appreciate a walkthrough for your latest GMA500 operating method, if you can spare the time.

Cheers,

Udi

Well, I have mplayer-vaapi working, except for subtitles, with our current drivers. And broken suspend is a show-stopper for me, so I'll stay for now with our current drivers.
