In the case of a remote desktop or a VM the virtual screen is likely
to be made of gum and you do want to change its virtual size
dynamically to have a 1:1 relationship between virtual and actual
pixels.

This is exactly what won't work in a VM/hotplug/whatever context. What
the user said basically assumes a fixed dpi and/or physical size,
which is not the reality. You absolutely do *not* want to trust the
user and have the system adapt auto-dynamically to changes.

That's a direct consequence of past GNOME everything-is-96-dpi
mentality. When you assume the DPI is fixed (or that it's in a config
setting no one changes and is initially set at 96) there's no need to
handle or test the changing dpi case.

Sure, it's a vm-specific behaviour (virtual screen which physical
dimensions can vary unlike real-world-screens) so it can only be fixed
in the vm stack.

No it doesn't. Don't conflate solutions to different problems in a
single mechanism. That thinking is a large part why we have the
current mess. Correct solution to different problems is rarely the
same.
X configuration is intrinsicaly static when use cases contextes are
increasingly dynamic.

Hello list,
I as wondering if there is a way to conveniently (as in "don't have to mess
around with the source") remap the three-finger-salute to kill the X-server.
We got some kind of 24/7 public viewing-only terminal here whose screen is
turned off every other week or so, and it sometimes does not come up again
properly without restarting X (driver is "nvidia", and we haven't got the
time to look into the issue any deeper) - however, the people around that
terminal with access to the keyboard are confused by having to hit those
three keys in parallel, which is why I would like to remap the killswitch to
some other, single key (like F12 or something).
Thanks in advance for any tips and comments!

Yes, I know - however, it is exactly that jump which I am trying to detect.
I vaguely remember something about all advanced features being disabled
when you access the touchpad via standard PS/2 protocol. What would I have
to do to try that? Just replace "synaptics" with "mouse" in my xorg.conf?

The "mess" you're referring to is the reason everything actually works.
I don't expect to ever see a working solution to my problem outside of
X. xrandr doesn't work, xf86-vmware doesn't work either.

I've understood. I am now applying the .fdi file.
Is it possible to make a .fdi file generic for every distribution,
which will not conflict with other touchpad/mouse configurations?

Do you really want to remap it? Why not just set Option "DontZap" True?

If I got it right he wanted to make it *easier* to restart... Though
your suggestion is probaby the better idea for a public place.

The thing is that this still forks, so you're still screwed on startup,
and you still have the XKM mess. All it does is cache the output
somewhere.

Yeah, I'm still happy to try the smashing-xkbcomp-in-its-current-form-in
thing again.

Maybe I need some help, I'm not so expert in this stuff... I edited
the fdi file and I copied it to
/usr/share/hal/fdi/policy/20thirdparty/
then I rebooted but the problem persists. Do I have to add some
xorg.conf tweak? or the udev rule too?
Thank you
