Hello,

I would like to know how to change the host resolution? At the moment I am "forced" to access the host using the internal VNC viewer. The default resolution isn't very usable and therefore I would like to set it to 1024x768 (at least).

I already tried those different lines in /etc/default/grub (not all at the same time ;))
Code:
GRUB_CMDLINE_LINUX_DEFAULT="quiet vga=791" 
GRUB_GFXMODE=1024x768 
GRUB_GFXPAYLOAD_LINUX=1024x768
... and I updated grub via update-grub.

I appreciate any hints or the solution.

Thanks in advance!
