Using dual graphic cards on Opensuse 11.2
추형석   2010.03.02   5092

If you want to use dual graphic cards on a desktop, it may not show the X windows when you connect two cards. At first we have to choose just one graphic card for monitor. This is different from which your graphic cards are. In the case of NVIDIA, (and please keep in mind that you should use same version of cards) execute following command as a root. #> sax2 -r -m 0=nv Here is a link and it says details about configuring cards. http://forums.opensuse.org/new-user-how-faq-read-only/unreviewed-how-faq/430150-opensuse-graphic-card-practical-theory-guide-users.html#post2099015graphic However, in order to use CUDA on dual NVIDIA GPU, there are some special issues to configure. 1. connect the Level 3 (just put number 3 on the grub and enter, it goes to level 3) 2. login as super user (root) 3. reinstall NVIDIA driver (I recommend to use 190.29 driver which enables the OpenCL) 4. type nvidia-xconfig -a 5. check the file /etc/X11/xorg.conf (there should be two "Device" for graphic cards, otherwise try again Section "Device" Identifier "Device0" Driver "nvidia" VendorName "NVIDIA Corporation" BoardName "GeForce GTX 2**" BusID "PCI:1:0:0" EndSection Section "Device" Identifier "Device1" Driver "nvidia" VendorName "NVIDIA Corporation" BoardName "GeForce GTX 2**" BusID "PCI:6:0:0" EndSection something like this) 6. then type startx or /sbin/init 5 7. also you can check these are usable from the SDK (If you install 190.29 driver, then try oclDeviceQuery or devicequery) Enjoy dual graphic cards! 이 게시물을 Twitter Facebook Delicious
