Hello,
I assume this is discussed regularely here, but as the technical situation is also changing rapidly I thought to just ask...
On my current laptop I can't render GEM windows on the secondary VGA output which is probably due to the lack of power of the graphics card. Therefore I'd like to know more before buying a new laptop (for which PD/multimedia work will be the main criteria).
So, are there any experiences with the nVidia GeForce Go 7600 or 7400 cards? Two Sony laptops I'm thinking about have these. I remember once reading about ATI cards being preferrable. But I'm not really sure anymore if this was related to _audio_ performance or linux installation (which is something I will hopefully tackle this year). Unfortunately there seems to be no specific information available on the nvidia home page which options are also supported on the secondary monitor.
Thanks for any hints Urs

The current issue of c't magazine (12/2006) compares Ati, Nvdia and Intel chips regarding their Linux compatibility, you may want to read it. They aren't very happy with Ati at all. Nvidia drivers seem to be okay, and of course only Intel has powerful open source drivers, because both Nvidia and Ati play hide and seek with open source developers. (That's why for me only an Intel machine was an option, but YMMV.)
Ciao

Thanks for the tip, I'll check that out.

Sorry for my ignorance: What do you mean by 'Intel machine'? A machine with an onboard Intel graphics chip? I read that the new (?) 915 chipset has (contrary to earlier onboard solutions) no negative impact on audio performance, but you have to make compromises with 3D performance (which is what I assume to be necessary for GEM and similar things). Am I talking about the right thing? Or are there laptops with dedicated video cards by Intel?
Thanks for any clarification Urs

Yes, an Intel laptop with an Intel gfx chip. ("Centrino")

I use it (with an MSI S260 barebone notebook), it has very good 3D performance IMO and doesn't interrupt audio. Of course it's not as powerful as the Nvidia chips, but it is more than powerful enough for what I do with Gem and audio. Btw: The new small MacBooks use the Intel gfx chips as well.

I thought that "centrino" reffered to the level of on-chip processor
cache, and that is why centrino chips are cheaper then the other intel
processors. As far as I know centrino machines include a high level of
wireless integrateion and low power applications like laptop usage. I
don't know that centrino means a certain graphics chipset, does it?

Please correct me if I am wrong, as I often am. :D
As far as graphics go, I am using an AMD64 laptop (in 32-bit mode
because I think PD's tables still don't work in 64-bit mode) with an
ATI 9600 M10 graphics chip. Fedora Core 5's Xorg recognized my chip (I
think using the R350 driver which is probably an eveolution of the
r300 driver which is still listed on sourceforge)
If you can send me a benchmark I will run it and let you know the results.

thats the difference between Celeron and Pentium
Centrino refers to the combination of an Intel cpu, and an Intel wireless card. Viiv refers to an Intel cpu and Intel video.
the Centrino platform goes thru revisions every 6 months or so. the current codenams is Napa, the last was Sonoma. the next one is Golan (which i find quite disrespectful to Syrians, but i digress,,)
Intel's wireless card is great, and along with the video card has excellent _open_ drivers for linux. ive got the s270, aka amd64+ati version of frank's notebook, and frankly it was prabobly the wrong choice. PD doesnt work natively, and the ATI video is beyond bad with X, despite it running circles around the intel in windows tests. once in a blue moon 3d accel will actually work. in XGL, using hardware accel causes a kernel panic, and using software rendering is much slower than no XGL at all. and theres visual artifacts in 2D mode when moving the pointer to the edge of the screen, not to mention various BadPixMap type of errors, none of these problems affect the reverse-engineered free drivers, but those don't support the VGA port or have 3D accel
in short. if you want performance and arent an open-source ideologist, get nvidia. if you want to sacrifice some performance for fully-supported free drivers, get Intel. and stay far away from ATI...
