  I'm used to using alt+left/right arrow to navigate back and forward in
  web browsers and elsewhere (nautilus)...  But on this fresh install of
  Ubuntu Gnome 15.10 beta, it seems to try and switch me between tty
  consoles (the ctrl+alt+f1 ones).  But it's not listed as one of the
  shortcuts in the "keyboard" menu, so I don't know how to disable it...

[Desktop-packages] [Bug 1698256] Re: Invalid, Meson-generated, valac arguments break the build

[Dan S.]

I upgraded to the newly released Meson build 0.41.1 (from 0.40.1), and
this isn't a problem anymore...

  I'm trying to build simple-scan according to the README file (on
