[Bug 1787267] Re: Can't type | ( pipe ) over vnc

[Phillip Susi]

** Description changed:

+ [Impact]
+ 
+ After upgrading from 16.04 to 18.04, users are unable to type a | or >
+ in their virtual machines when accessing them via vnc.  This happened
+ because upstream added a key to the keymap that can also produce these
+ symbols and exists only on European keyboards, but it uses different
+ modifier keys to produce these symbols so trying to type a | or a >
+ results in a < instead.  Simply removing this new non-existent scan code
+ from the keymap resolves the issue.
+ 
+ [Test Case]
+ 
+ Start a virtual machine and connect to it via vnc.  I am using
+ "tightvnc" on Windows, and upstream indicated that some vnc clients send
+ the raw scan code instead of keysyms, in which case this issue would not
+ arise.
+ 
+ [Regression Potential]
+ 
+ There should be no regression potential for actual en-us keyboards since
+ this key does not exist.  European keyboards may be unable to use this
+ other key they have unless they set the correct keymap, but all of its
+ symbols are duplicates from other keys on the keyboard, rendering it
+ fully redundant.
+ 
+ [Original Description]
+ 
  I tried booting some Ubuntu images today on my Xen server where I use
  VNC to remotely access the VM, and am unable to type a | ( pipe ).  I
  opened the keyboard layout utility and when I press the \ key, it
  recognizes it, but when I hold shift and press the key, it claims that I
  am pressing some key between left shift and Z that does not actually
  exist on US keyboards, and that types a > instead.
  
  This did not used to happen, and probably started when I upgraded the
  server from 16.04 to 18.04 a while back and I just haven't been testing
  VMs since then.

** Changed in: qemu (Ubuntu)
       Status: New => In Progress
