Comment 3 for bug 1744357

Tested the Xubuntu daily live i386 ISO (2018-01-20) using QEMU/KVM on 16.04 and also couldn't reproduce the boot failure. Selecting "Try..." mode the system reached the desktop. It did seem to fail to properly pain the desktop or panels but was fine after "sudo systemctl restart lightdm".
