Description
Hi,
the key AltGr (right alt key) is not working in the vnc-console.
This is very bad for users with a german keymap because without it no @, |, \, {, }, ... is working.
Googling this problem with novnc and kvm you can find a lot of notes but none of them are helping.
From the novnc-side this issue should be fixed since 0.5.1. Maybe it's a libvirt/qemu problem.
Regards,
Peter

Hello,
i have the same problem (using iceweasel 38.6.1). I tried to debug the noVNC code and found the following lines in the keyboard.js from noVNC:
// Firefox sends keypress even when no char is generated.
// so, if keypress keysym is the same as we'd have guessed from keydown,
// the modifier didn't have any effect, and should not be escaped
if (queue[0].escape && (!cur.keysym || cur.keysym.keysym !== queue[0].keysym.keysym)) {
cur.escape = queue[0].escape;
}
When i comment this out and run Sunstone in development mode, AltGr is working for me.
Additionally, there is no problem with AltGr when i connect with vncviewer. So it seems to be an issue with noVNC?
Hope, this information will help to fix the bug.
Kind Regards,
Steffen

Hi Steffen,
Thank you for the detailed solution. Since this is not part of the Sunstone code, would you mind to report this issue in the noVNC Github?

Hello Daniel,
i opened an issue (https://github.com/kanaka/noVNC/issues/595). But there is already a quite similar issue, that was closed (https://github.com/kanaka/noVNC/issues/429).

- Category set to Sunstone
- Priority changed from Normal to High
- Target version set to Release 5.4
- Affected Versions Development, OpenNebula 5.0 added
To consider:
- novnc can be updated, but the new version may require some changes in our code (see: https://github.com/kanaka/noVNC/releases)
- our current version (0.5.1) can be replaced with the fork mentioned here: https://github.com/kanaka/noVNC/issues/21
In both cases it looks like removing the graphics/keymap attribute from libvirt's xml is required to make it work.
