Dual Head graphics card without binary drivers?
in [Linux Hardware]

From: Felix Schwarz on 16 Jan 2008 05:19 Hi, I did not follow linux graphics card driver development for some time. I'm looking for new graphics card for dual head support with CentOS 5.1. Requirements/Wishes: - no binary drivers (I think they won't work with Xen anyway) - works with CentOS 5.1 (kernel 2.6.18, X.org 1.1), hopefully out-of- the-box - DVI would be nice, but I can switch to VGA if necessary - each head must do a minimum resolution of 1280*1024 - no AGP slot, I can only use PCIe or PCI - 3D support is not relevant - no need to buy low-budget, so price "does not matter" - I don't want to spend too much time on buying the card so getting it on eBay is probably not an option. I'm very grateful for any buying recommendation. If there is no card which matches the profile above, are there some products with binary drivers I which can be recommended? Thank you very much fs

Most ATI and Nvidia PCI or PCIe cards with two outputs should satisfy your requirements, except Radeon cards higher than the X1050 (there's free driver work underway for them, but probably not out-of-the-box for your distribution) and maybe the newest Nvidia cards; I don't know which Nvidia cards are supported by the nv driver on your distro, so if you want to buy one of them, look for other advice, too. Looking at what's out there, I see that various PCI Gforce 6200 cards and lots of PCIe Gforce cards are available as well as PCI Radeon 7000 and 9250 cards, and PCIe Radeon X1050 cards and a few X300s. 2x DVI seems to be available mostly on the relatively new and fast cards (which have a fan), those I mentioned usually do 1xDVI, 1xVGA. - anton -- M.

If the cards Anton's recommendations doesn't fit your needs http://www.matrox.com/graphics/en/finent/products/gseries/g550pcie.php might do. I've used G based Matrox for many years with the free Matrox driver and they work great under Linux. Note that the G550 is a really old piece of hardware, but 2D speed is still adequate. -- Lasse Jensen [fafler at g mail dot com] Linux, the choice of a GNU generation.

Does it do 2 x DVI at 1280x1024 with the X.org mga driver or do you need the Matrox "open-source" driver with the closed source binary HAL? <http://www.matrox.com/graphics/en/finent/news/features/g550_pcie.php#Linux> The open-source driver includes a closed-source binary HAL (Hardware Abstraction Layer) file provided by Matrox to enable certain advanced features. "certain advanced features" and no reference what these could be, they really must be kidding. Regards... Michael

I cannot see why it shouldn't. The mga driver supports use of dual monitors and 1280x1024 isn't that much. The 16 mb available for each head is more than enough for 2D. <http://www.matrox.com/graphics/en/finent/news/features/g550_pcie.php#Linux> > > The open-source driver includes a closed-source binary HAL (Hardware > Abstraction Layer) file provided by Matrox to enable certain advanced > features. > > "certain advanced features" and no reference what these could be, they > really must be kidding. I think they are. I've never used the HAL module from Matrox and i have no idea what it does. -- Lasse Jensen [fafler at g mail dot com] Linux, the choice of a GNU generation.
