I am running a CentOS 5.3 x86_64 (fully updated as of today). It has a video card I cannot identify -- I run lspci and it identifies itself as:
01:00.0 VGA compatible controller: nVidia Corporation Unknown device 0615 (rev a2)
The previous admin left me with the linux driver NVIDIA-x86_64-185.18.31-pkg2.run and having installed that it seems to work properly in single monitor mode.
I have two identical monitors. Both are connected through DVI connectors on the back of the video card.
However when I try to enable dual-monitor mode through the Display menu applet, it doesn't work. The computer starts the NVidia driver and then kicks back to the command prompt.
The tail end of the Xorg.log file is:
Backtrace: 0: X(xf86SigHandler+0x71) [0x4865b1] 1: /lib64/libc.so.6 [0x303de30280] 2: /usr/lib64/xorg/modules/librac.so [0x2aedd36f803a] Fatal server error: Caught signal 4. Server aborting (II) Screen 0 shares mem & io resources (II) Screen 1 shares mem & io resources
I have also done some fooling with the xorg.conf file directly such as duplicating the monitor definition between screens, but it always dies the same way.
Does anyone know how I might identify this card's chip properly to ensure I have the correct driver, and is there a good guide on the web anywhere for manually configuring two monitors off of one video card?
Thanks for any pointers.
