Hi, I try to install vtune on centos7, which shows the following message: Xorg X11 libXss runtime library is not found. 'Graphical user interface' component of VTune Amplifier cannot be installed. The install program cannot detect the Xorg X11 libXss runtime library required by the graphical user interface of the product. Contact your system administrator to install the library or install the product on a compliant system. Otherwise, go back and unselect 'Graphical user interface' component. How to install Xorg X11 libXss runtime library? Thanks! Regards Andrew
