Tesla C2050 display desktop GPU3 on 4 activate by default

[Duga]

Hello

we’ve bought 4 Carri HighStation 5600 for CUDA Computing. There are 4 Tesla C2050. We’ve choosen to use one tesla to display the Linux desktop (RHEL6.1) because the internal video card (Aspeed AST2050) can’t display on 16:9 widescreen.

01:00.0 VGA compatible controller: ASPEED Technology, Inc. ASPEED Graphics Family (rev 10)

05:00.0 VGA compatible controller: nVidia Corporation GF100 [Tesla C2050 / C2070] (rev a3)

07:00.0 VGA compatible controller: nVidia Corporation GF100 [Tesla C2050 / C2070] (rev a3)

81:00.0 VGA compatible controller: nVidia Corporation GF100 [Tesla C2050 / C2070] (rev a3)

82:00.0 VGA compatible controller: nVidia Corporation GF100 [Tesla C2050 / C2070] (rev a3)

By default, the 4 workstations use the Tesla on BusID 82:00.0 :

cat /var/log/Xorg.0.log

…

(II) Primary Device is: PCI 82@00:00:0

Is there anyway too choose another card to display the desktop ?

We’ve tried to force another bus id in /etc/X11/xorg.conf with the line "Option BusID “XX:XX:XX”. But it doesn’t work. It’s still displaying on 82:00.0. Why ?

Thanks for your help.
