Xorg log for VBoxVGA as graphic adapter
I have a virtualbox VM with FreeBSD 12.2-RELEASE-p4 as guest on a Windows machine (VirtualBox 6.1.18 r142142). After updating to virtualbox-ose-additions-6.1.18 (latest repo, all packages are up to date), I got a blank screen instead of Lxde. I normally use the VBoxVGA as graphic adapter but tried VMSVGA as well (with the proper driver installed): same result.
See the provided log.
Initially, I experienced the same problem. and I took also part on said Forums thread (user obsigna).
After some trials & errors, I got it to work. I vaguely remembered that some weeks ago I read somewhere, that it is important to orderly finish the desktop session before deleting the old and installing the new virtualbox-ose-additions. I cannot find this anymore, but I am sure that I did not dream reading it. Anyway this worked out. I started with an almost identical snapshot, which had still the old additions installed. In order to be really on the narrow road of said hint, I did the following:
1. deactivate the vbox entries in /etc/rc.conf
2. restart into the GNOME desktop
3. delete the old additions
4. restart into the GNOME desktop again
5. install the new addions and activate the vbox entries in /etc/rc.conf
6. restart into the GNOME desktop again, now with new additions
Now everything is working fine. Most probably, step 4 was not necessary. But so what, its done and everything is working now.
This trick doesn't work for me.
Looking at /var/log/messages, I found: "console-kit-daemon: WARNING: Error waiting for native console 9 activation: Inappropriate ioctl for device"
If it can help...
