Unity-Linux under MINT Cinnamon 18 Orbit

[DeineMamma-de]

Hi Guys, i have a following noobfull question:

Unter Mint Cinnamon i can not use the orbit function of the Scene View because if i hold ALT+LMB i pan my whole window instead of orbit around my selected object.
Under my shotcut setting i could not find a shotcut including a mouse button.
Than you in advance.

Sorry Guys i found the setting under Systemsettings=>Windows=>Behavior under “Special key to move and resize windows”
