Using Framebuffer instead of X Windows

gistfile1.txt

Can be used from qemu Ubuntu instance (see other gist).

Clone and build this on the host:
https://github.com/ponty/framebuffer-vncserver

Run it *as root*:
sudo ./framebuffer-vncserver -t /dev/input/by-path/platform-i8042-serio-1-event-mouse -k /dev/input/by-path/platform-i8042-serio-0-event-kbd

You can use the direct /dev/input/eventX as well if you want.

Then you can use vncviewer to connect just as if it was an x window connection.

fbset can be used:
fbset -g 1024 768 1024 768 32

And with no params to see settings:
fbset

Configurations:
cat /sys/class/graphics/fb0/modes

You can make squeak vm transmit to framebuffer - again run as root:
sudo cogspur/squeak -vm-display-fbdev Cuis-Smalltalk-Dev/Cuis6.0-5069.image

Grub resolution:
/etc/default/grub
GRUB_GFXMODE=1024x768x32,auto
