Alt gets stuck leaving the teamviewer window with Alt+Tab

I use Teamviewer on Ubuntu (Not sure if the problem is the same on Windows).

Whenever I use Alt+TAB to change the focussed window on my computer to another window while the remote window has focus the remote window catches the Alt keydown event but not the Alt release event! So when I get back to the remote Teamviewer window the remote computer still has the Alt Key stuck pressed.

How can I prevent that the Alt-key gets stuck on the remote computer?

Solution 1:

This creatively titled TeamViewer support thread discusses this problem, and unfortunately the response from TeamViewer was "cannot reproduce."

Thank you for your patience.

We have received word from our QA team. They advised that the issue was not able to be reproduced, using several different models / brands of keyboards.

Even though that thread is for Windows, some of the workarounds discussed are system agnostic, and should be faster than using CompizConfig.

1. In the TeamViewer remote window, try mashing the modifier keys AltCtrlShift
2. In the TeamViewer remote window controls, disable and re-enable the Send key combinations option

In my experience, option 1 works to release a stuck key.

Solution 2:

I also came across the same problem.

Here is a workaround I have found:

1. install CompizConfig Settings Manager via Ubuntu software center
2. Locate the unity plugin inside the CompizConfig Settings Manager
3. From the switcher tab disable Alt+Tab combination while using Teamviewer
4. undo this setting when you are finished using Teamviewer.
