Dual Nvidia Card Troubles on Fedora
We have a nice Dell box with two fancy Nvidia graphics cards in. Scientific Linux 5.x (i.e., RHEL 5.x) detects the cards, nice GUI, fine. Fedora 11 get upset, won't give a GUI! Seems odd.
Install the Nvidia Nvidia Driver (Rather than the Xorg One)
Add the RPM Fusion repos:
rpm -Uvh http://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-stable.noarch.rpm rpm -Uvh http://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-stable.noarch.rpm
Add some packages:
#### yum install xorg-x11-drv-nouveau # ...the free driver... yum install xorg-x11-xinit yum install xorg-x11-fonts-75dpi yum install xterm yum install xorg-x11-fonts-misc yum install kmod-nvidia xorg-x11-drv-nvidia-libs yum install kmod-nvidia-PAE
Configure Nvidia Driver
livna-config-displaywhich generates an appropriate Xorg config file (/etc/X11/xorg.conf), at least it should do!
DRI-Related Errors
yum install mesa-dri-drivers
GLX-Related Errors
Use the Nvidia driver-specific libglx.so, not the one provided by Xorg:
cd /usr/lib/xorg/modules/extensions mv libglx.so libglx.so___ ln -s nvidia/libglx.so libglx.so
More Weirdness
Some weird stuff, but the clue is in there:
The system logs include some disturbing looking NVRM messages however: NVRM: RmInitAdapter failed! (0x25:0xffffffff:1011) NVRM: rm_init_adapter(1) failed allocation failed: out of vmalloc space - use vmalloc=<size> to increase size. NVRM: RmInitAdapter failed! (0x25:0xffffffff:1011) NVRM: rm_init_adapter(1) failed allocation failed: out of vmalloc space - use vmalloc=<size> to increase size. NVRM: RmInitAdapter failed! (0x25:0xffffffff:1011) NVRM: rm_init_adapter(1) failed NVRM: RmInitAdapter failed! (0x25:0xffffffff:1011) NVRM: rm_init_adapter(1) failed NVRM: RmInitAdapter failed! (0x25:0xffffffff:1011) NVRM: rm_init_adapter(1) failedOut of VM. So add something to the each kernel line in the GRUB config to increase it:
/vmlinuz-2.6... root=/dev/s... ... ... ... vmalloc=256MB
No Screens Found
(II) Primary Device is: (EE) No devices detected. Fatal server error: no screens found
The driver is getting confused over the two cards it finds on the PCI bus (see output from lspci to see what the driver sees). So specify the card to use in xorg.conf:
Section "Device" Identifier "Videocard0" BoardName "needname" Driver "nvidia" BusID "PCI:2:0:0" EndSectionand we have our final working X11 config file.
It's odd that Scientific Linux does not require this.
