I have a dual boot configuration that had previously been working well here.
-- Fedora 7 32-bit and x86-64, on separate partitions.
-- NVIDIA driver: NVIDIA-Linux-x86_64-169.12-pkg2
-- Running dual screen "TwinView" mode
Out of the blue, when I went to boot into x86-64 this afternoon, X Windows failed to load.
xorg.conf has been unchanged for months, and is identical between 32-bit and 64-bit versions. My 32-bit setup continues to boot correctly. The 64-bit partition was working fine earlier this week, and today it fails to load.
The last 3 lines of the error screen read:
(WW) NVIDIA: More than one matching Device section found: Videocard0
(II) Module already built-in
/usr/bin/Xorg: symbol lookup error: /usr/bin/Xorg: undefined symbol: Bui
and that's it!
If I attempt to reconfigure from this point, I enter my root password, and the screens go blank. The only way I can tweak anything is by setting inittab to 'id:3:initdefault' or by accessing files via my 32-bit version.
I have reinstalled the drivers, switched back to single screen, and tried switching back to default VESA drivers.
I have Xorg.0.log and xorg.conf available for review, if necessary. My matching 32-bit version is running perfectly, so I can also easily compare files between operating systems.
I'm relatively new to linux, so I'd appreciate any suggestions you can offer. Thanks!
