I have Debian running on my VB and installed guest-addons.
Prior to installing, the VM screen would just be the small window surrounded with black.
After checking threads in this forum, I found out that this can be solved by installing guest-addons.
Now, after installing guest-addons I have two problems.
1. The screen size is bigger BUT does not fit into full screen.
2. when using shutdown -r now it stops at the line
stopping portman daemon
and doesn't continue after that. The VM works fine after I stop it using the power-off signal.
What can be done to rectify these issues?
