[Bug 520546] Re: Alt+KEY incorrectly behaves like Ctrl+Alt+KEY, and/or unwanted VT switch from Alt+Left/Right

[Robie Basak]

Accepting the fix into stable releases. Note that the fix only prevents
new breakages; existing affected users will not be unbroken without
rebooting (or rebooting X).

** Description changed:

- 
  (console-setup)
  [Impact]
  
-  * keyboard-configuration's postinst changes keyboard mode breaking X
+  * keyboard-configuration's postinst changes keyboard mode breaking X
  keys.
+ 
+ [Workaround]
+ 
+ Reboot (or restart X) and the problem will go away.
  
  [Test Case]
  
-  * Ssh to a system or open a terminal and unset DISPLAY
+ [racb] Note that upgrading to the fixed package will not fix the problem
+ for affected users; you must reboot (or restart X) as above. The fix
+ only prevents the problem occurring again.
  
-     $ echo $DISPLAY

+  * Ssh to a system or open a terminal and unset DISPLAY
  
-  * Check kbd mode, should be raw (set by kbd_mode -s) or unknown:
-    $ sudo kbd_mode
-    The keyboard is in some unknown mode
-    $ sudo kbd_mode
-    The keyboard is in raw (scancode) mode
-    $
+     $ echo $DISPLAY
  
-  * Install or reinstall kbd-configuration

-    $ sudo apt install --reinstall keyboard-configuration 
-    ...
-    Setting up keyboard-configuration (1.178ubuntu11) ...
-    Your console font configuration will be updated the next time your system
-    boots. If you want to update it now, run 'setupcon' from a virtual console.

+    $ sudo kbd_mode
+    The keyboard is in raw (scancode) mode
+    $
  
-  * The unfixed package sets the kbd mode to unicode:
+  * The unfixed package sets the kbd mode to unicode:

-    The keyboard is in Unicode (UTF-8) mode
-    $

+    The keyboard is in Unicode (UTF-8) mode
+    $
  
  [Regression Potential]
  
-  * The change may break debian-installer changing the keyboard mode, this should also be tested.
-  * In general changing the postinst script may make the package unable to install, but this is tested in generic environment and the change to the postinst script is very small.

  [Original Bug Text]
  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.

** Changed in: console-setup (Ubuntu Disco)
       Status: In Progress => Fix Committed

** Tags added: verification-needed verification-needed-disco
