Try / Copy this: --- $ tail -n 2 /etc/group DUMMY:x:65535: $ --- I have experienceed that the last line in the group file is "not in use". (Maybe because it was missing a LF). The above is a "marker" to help avoid the problem. Nvidia drivers requires th euser to be in 'nvidia-persistenced' group. I had that group on the very last line in the group file, which simply didn't work. -- /Hannu ------------------------------------------------------------------------------ Dive into the World of Parallel Programming The Go Parallel Website, sponsored by Intel and developed in partnership with Slashdot Media, is your hub for all things parallel software development, from weekly thought leadership blogs to news, videos, case studies, tutorials and more.
