Stupid question

[hotsouce]

Hi,
The more I read the less I know ;-)


I want buy notebook with GMA 4500HD.

I have one fundamental question ;-)

Does Ubuntu supports this video card ?
- Auto-detect card
- Compiz will works well
- I can watch movie

If GMA 4500HD is good solution for laptop + Linux ?

Now i have GF 8600gt and i haven't any problem.

[hotsouce]

My question was maybe no precision : Does opensource driver supports 3d desktop, movie etc. ?

Via VA-API you could get mpeg2 accelleration now, but currently no h264, also vc1 accelleration is not even planned. Current Nvidia gfx chips support VDPAU which is the best solution for hd video playback. So it depends of the definition of "movie" ;)

[hotsouce]

when i wrote "watch movie" i think about divx/xvid movie no HD ;-)

[Kano]

Well i think of full hd m2ts ;)

[hotsouce]

well... How looks compiz and ordinary working like web browsing with intel.Are any problems?. I have to make decision about buying or not notebook with intel card.

[hotsouce]

OR I asked different all owner laptops with intel 4500HD: if you have second choice will you buy laptop with intel or buy something with AMD/NVIDIA ? (Linux OS of course)

[RobbieAB]

I bought Via...

[hotsouce]

via means "via technologies (S3)" or intel - sorry i'm not expert ;-)

[hotsouce]

Could someone explain me what RobbieAB think about writting " I bought Via... "

[Kano]

via is not really a valid choice. intel only is when you want to test hyperspace or with vt capable cpu even hyperspace hybrid. otherwise i would definitely get a dedicated nvidia gfx chip.

It's not a laptop, but I do have a X4500HD and it's working very well. There shouldn't be any problems at all with web browsing, movies, compiz etc.

There are however at least two caveats:
- Gaming, anything up to and including Doom 3 should be okay, but support for Wine with Mesa just isn't that good.
- Hardware acceleration for video decoding is missing. It's apparently being worked on though.

[hotsouce]

OK, i understood. Thanks for ALL.

Any idea when we should see hardware acceleration for H264 and VC1 ? Is it a matter of months or more ?
I'm a little disappointed that Poulsbo chipset have hardware acceleration fo video decoding available right now although the driver is closed source, whereas GM45 chipset is fully open source with all the documentation necessary and it is still not available (just MPEG2 which I really don't need).

I've found a lot more 3D problems than just wine games with the X4500 when using the drivers included with Ubuntu 9.10, like how Yo Frankie! crashes when shaders are enabled, Sauerbraten can only display the menu and the 3D scenes in On the Rain-Slick Precipice of Darkness are entirely black (it seems to me that in the latter two cases, the scene isn't being cleared, and nothing 3D is being drawn. Both of these games were fine on Ubuntu 9.04 using the Xorg-edgers packages from September or so).

[hotsouce]

I see that it isn't perfect. Now i'm working on Ubuntu 9.10 i very fresh realase maybe in near future this bugs will be remove.

Yo Frankie is a known problem with Mesa, file bugs for the rest of them. git-bisect is both easy and simple to use :)

No idea, I would also very much want to know what the plans are.

At least from looking at the Windows side, this chip really seems to be targeted at video decoding, so it's a bit surprising that it's taken so long.

Hi,

Do you plan to support H264 and VC1 decoding anytime soon on GM45?

Thanks.

Yes, we do have plan for that.

Thanks

Are something easier methods than git-bitsec to eliminate this bugs?

[whizse]

Having a bisect ready for a regression is usually the best way to make sure bugs are fixed quickly (second only to submitting a patch of course), but all bug reports are valuable.

Mesa in general seem to suffer a lot from having too few users willing to try the latest stuff and report problems.

Don't worry, there's already a bug open (https://bugs.launchpad.net/ubuntu/+source/mesa/+bug/443375) for Sauerbraten (and it's apparently fixed with bleeding-edge kernel and Intel drivers), I just wanted to share my experiences. :)
