Xorg can't do anything about intercepting Alt-key, it's the kernel which
takes the shortcut away.

As mentioned in https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1508146 , Ubuntu probably wants to apply the attached patch.

Can somebody with t he proper rights do something about this? That patch
exists since months now...

Title:
  Alt+KEY incorrectly behaves like Ctrl+Alt+KEY, and/or unwanted VT
  switch from Alt+Left/Right

Status in console-setup package in Ubuntu:
  Confirmed
Status in linux package in Ubuntu:
  Confirmed
Status in xorg-server package in Ubuntu:
  Confirmed

Bug description:
  WORKAROUND:

  sudo kbd_mode -s

  ORIGINAL DESCRIPTION:

  I'm running Ubuntu Lucid development branch.

  Pressing alt-f2 switches the screen to the second virtual terminal.
  Alt-f3 does the same to the third and so on. I expected alt-f2 to open
  the run dialog.

  I'm pretty sure that my keyboard is not malfunctioning as I can use
  all my applications normally. (Pressing O and Ctrl-O do not have the
  same effect.)

  I'm not sure which package I should file this bug against. I'll
  happily do an apport-collect once I know.
