http://ubuntuforums.org – Hi there, After I performed fresh install of Ubuntu 12.04 on sda drive, I cannot change perms on one of the files to make it executable. I own the file as a user, i ran chmod as user or root with either +x, or u+x, or 700. Command runs, but file is still rw, not rwx. I even tried to right click on it using GUI, then click the box for the "executable". It marks it as executable, and then immediately removes it by itself. Anyone ran into this before? (Hardware)
