Hello:
It seems every time xorg is updated it clobbers my Nvidia driver
and, all of a sudden, those cool GLX screen savers, not to mention
Google Earth (a mission-critical application!) don't work. If I use
nvidia-installer to UNinstall the drivers, it tells me
'/usr/lib/xorg/modules/extensions/libglx.so is not a symbolic link',
whereas, right after installing the nvidia drivers, it IS. So, what
I'm wondering is whether there's any way to protect a symbolic link
from being overwritten. Ordinarily, if I want to protect a file,
I'll make it read- or read-and-execute-only, but a symbolic link is
always 'lrwxrwxrwx' and 'chmod 555 link' just changes the
permissions on the underlying file. Perhaps that will protect the
link from being replaced with a file, but I'm not confident! A
hack solution would be simply to rename the underlying file to the
link name and make THAT unwritable, but I think that might confuse
the nvidia installer.
Any suggestions will be welcome.
