I'm working on an Ubuntu server without X and I would like to easily change the resolution.
In order to do that, I have to specify
GRUB_GFXPAYLOAD_LINUX=1280x800 in the file
sudo update-grub, and then reboot.
On a desktop installation, changing the resolution is muuuch faster : You just click and it changes immediately. How is that? How does this work?
Is it possible to do hot swapping like this without X ?
