Xfbdev is a display server for the X Window System Protocol Version 11 that that uses the framebuffer provided by the Linux framebuffer device.

It works in x86_32 and x86_64 architectures.

Xvesa doesn't use configuration file like Xorg.

Xvesa -display :0
Xvesa -force
Xvesa -videoTest

Shortkeys:

Ctrl-Alt+Backspace - close Xserver
Ctrl+Alt+F1

• hardware acceleration could be achevied if your kernel driver supports your GPU
• it doesn't support DPMS
• only supports Latin-1 keyboard keymaps

Xfbdev server was written by Keith Packard.

in order to have working framebuffer you need to add bootcode to you Linux bootloader.

vga=ask (you will choose screen resolution)
vga=0x311 (640x480x16
vga=786

If you don't have /dev/fb0, thit means framebuffer was not turn on.
