I have seen many related posts and tickets about problems if 3D accel is on, especially (or only?) with (64bit?) Linux guests. However, most either don't provide a solution, or it hasn't worked for me.
I currently have a Gentoo Linux host, kernel 4.1.15. Virtualbox 5.0.16, with the guest additions from the download page 5.0.17-106140. The host is KUbuntu 15.10 with kernel 4.2.0 and xorg 1.17.2. I have had various of the guest systems virtual box packages installed. None are currently installed, but it does not seem to have made any difference. I see no errors in the virtualbox additions install logs on the guest. When I start the guest, the login screen looks fine, and when I log in, the guest initially looks fine, with two applications visible and with icons on the lower panel. However, once I try to do anything, the app windows just disappear, as does the panel. If I hover the mouse over the panel, I can generally click, but only the task launcher seems to work, and even there, once I launch an application, it disappears. Alt-tab does show the icons, and I can circle through them, but no matter where I stop, I never get any application window visible. The only way I have gotten any information is to ssh in from a terminal on the host. The most relevant line I see from the X log is "(EE) Failed to load module "vboxvideo" (module does not exist, 0)" If I turn off 3D accel, everything seems to work fine. My host video is "NVIDIA GPU Quadro FX 1700 (G84GL)" using nvidia-drivers 340.96. What other info should I post, or what else can I do to troubleshoot?
