Guide to Get the Best Performace from the GMA 500

[tista]

I can't test it right now, because I still have the EMGD driver installed, but I got a lot of [ mpeg 4]wrong code for xxx errors.

Hi, th3voic3.

If you have still some logs with errors, would you paste via http://paste.ubuntu.com/ and post it?

I want read them.

cheers

Ok I have purged the EMGD drivers and reinstalled the psb ones to reproduce the problem.

These are two logs of videos that come up with artifacts

Hi, geveno.

Thank you for your post! and I've read whole things.

I also think they would be alright...

but Only one line what I couldn't miss in Xorg.log line 368:

(==) Depth 24 pixmap format is 32 bpp

I'm not sure which is right or wrong because I don't know how EMGD framebuffer works, however, I felt a little bit strange...

cheers

Hi Tista!
When I read this line, I thought it was strange too but I verified with psb driver and this line appeared too exactly the same and I don't have any problem with psb drivers... Does your modeline is the same than me?

Hi.

Yes, the same exactly. mine is showed below:

Modeline "1600x768_60.00"  99.98  1600 1680 1848 2096  768 769 772 795  -HSync +Vsync

So, I've noticed your x conf line 50:

Option "ALL/1/Port/4/Attr/26" "18"

is setting of PANELDEPTH. 18bit is incorrect !!
please set it to "24" or "32".

Brightness hotkeys fixed in psb-kernel-source module thanks to D.G.Jansen patch!
Official bug report: http://code.google.com/p/gma500/issues/detail?id=10

Tried on Maverick, GNOME and Acer751h
It's currently packaged in gma500/fix ppa until we have enough feedback to move it into mainline ppa.

Do you think this could also be applied to the EMGD driver?

Brightness control patch works fine on my Aspire One 751h (2 GB) running Maverick. No nasty side effects as yet... Nice work!

Any progress yet with Xv? (Guess I'm just never satisfied! )

It is a little fix in kernel module, emgd has a opensource module, so even not being an expert i would say yes.

All intel chipset are blacklisted for brightness control via acpi, poulsbo is a bit different so it could be enabled. Take a look at patch.
