I am using a barebones Ubuntu 16.04 in VirtualBox, macOS host. Up to VirtualBox 6.0.0, everything was working fine. But with VirtualBox 6.0.2, 6.0.4 and 6.0.6, Unity crashes on startup. In ~/.xession-errors
I see lines similar to
upstart: unity7 main process (3256) killed by SEGV signal
upstart: unity7 main process ended, respawning
upstart: unity7 main process (3290) killed by SEGV signal
upstart: unity7 main process ended, respawning
upstart: unity7 main process (3324) killed by SEGV signal
upstart: unity7 main process ended, respawning
upstart: unity7 main process (3358) killed by SEGV signal
Is anyone else experiencing this, or is it specific to my setup? Is there any other solution than downgrading to VirtualBox 6.0.0?
Turning off 3D acceleration in VirtualBox fixes the problem, but also makes Ubuntu unusably slow.
