I used the offline installer to install QT 5.5.1 (32 bit) in Linux Mint Cinnamon 17.2 (32 bit) in VirtualBox. Install was OK. Then QT creator doesn't launch. QT 5.5.0 works OK. Any ideas anyone?

Edit: I tried "-noload Welcome". Doesn't work. My Linux Mint installation has 2 desktops to choose from on login: Cinnamon and Xfce. Could the installation have gotten confused with these 2 choices? Qt creator for 5.5.1 doesn't launch in either desktop. But Qt creator for 5.5.0 works fine.

From the command line it says could not initialize GLX.

With VirtualBox 3D acceleration for the display turned off for the virtual machine it works fine.
