When I run :
sudo /opt/genymobile/genymotion/genymotion
I've got this error :
Logging activities to file: /root/.Genymobile/genymotion.log
./genymotion: symbol lookup error: /usr/lib/x86_64-linux-gnu/libGL.so.1: undefined symbol: drmGetDevice
Go to the directory where you have installed genymotion and remove libdrm.so.2
