if you built the source
( and KEPT IT )
just run ( as root) in the build folder
Code:
su -
cd to/the/build/folder
make uninstall
most ( but NOT all ) make files have a "make uninstall" section
if it is a .bin( AKA .run) installer
rerun the installer with the option " --uninstall"
see the "help" section in that installed
for example the nvidia.run driver
Code:
sh NVIDIA*.run --help
