Re: [AD] Fullscreen problems on Linux

[Daniel Leslie <dan@xxxxxxxxxx>]

My mistake, I haven't used Windows in years so my recollection is hazy. I could have sworn that UAC prevented applications from changing display settings if the current user wasn't an Administrator.

Regardless, if I read that post correctly, it seems like they want to prevent applications from mucking with the display settings unless authorized to do so.

Not sure what you mean, Windows doesn’t need UAC to go fullscreen so how is that relevant?

Basically, they're trying to avoid nefarious applications taking hold of the display/compositor and making a mess of things.

This was once a problem with Windows but they've fixed it by introducing another annoyance: UAC.

In effect, that freedesktop.org post is advocating for some form of Linux-equivalent to UAC authorization prior to engaging in mode setting.

Just seems like excuses for a badly designed desktop. Windows has done mode

can't it be done on Linux?

Right, I feel developers are forgetting about games on Linux. If they kept
games more in mind, then maybe Linux would actually start to get traction on
the desktop, but no... Maybe we should protest a bit more, but I wonder if
it would help any.

I was checking a bit if wayland/weston tried to solve better than X, this
but it's just as bad really

See this comment on a port of xrandr to wayland:

"For standard applications, I believe the intention is that any modesetting
they do will be done in a very controlled manner through the shell." --Jason
Ekstrand

(http://lists.freedesktop.org/archives/wayland-devel/2014-February/013487.ht
ml)

So actually, things might even be worse. Mode setting will not be directly
available without root permissions, and we'll have to beg the shell (window
manager) to set the mode for us and hope that it really does mode set for us
and not just give us a full screen window in stead. Meh...

Kind Regards,

B.
