Thank you for sharing this information. I figured out KMS stands for
kernel mode switching and UMS for user mode switching. I also read some
background information on what it does and why.
$ modinfo i915

echo "options i915 modeset=1" | sudo tee /etc/modprobe.d/i915-kms.conf
Rebooted my system. While the screen output behaves differently xrandr
is unable to switch to my VGA monitor. When I change the modeset back to
zero I am able to switch to the VGA monitor.
When the modeset=1 the most significant change I can see the higher
resolution for the tty's, but without xrandr functionality I can't do
much with it.
So I am back to modeset=1 and still having the issue that my cursor
becomes invisible when switched to VGA only with xrandr.
Any help is appreciated, have been working on a 10" netbook screen for
days now and I don't think this is good for my eye :)
Thanks in advance,
Best regards,
Jelle
