ginoputrino opened this issue May 23, 2011 install script does rm -rf /usr for ubuntu An extra space at line 351: rm -rf /usr /lib/nvidia-current/xorg/xorg causes the install.sh script to do an rm -rf on the /usr directory for people installing in ubuntu. Totally uncool dude!!! The script deletes everything under /usr. I just had to reinstall linux on my pc to recover. Removing the space will fix
