Ubuntu freezes when running steam game counter strike and hitting the Windows key

Question

I recently updated Ubuntu to 15.10, and since whenever I am playing counter strike on steam and hitting the Super key, volume up, volume down, mute or any key-bored button that will show a UI over the counter strike game window Ubuntu freezes!

The only thing I can access is the terminal using Ctrl+Alt+F1.

Any ideas how to fix this?

Answer 1

I faced same problem sometime ago with all full-screen app using wine. There multiple ways the may lead to same result:

• Changing keyboard may help. I'm using two laptops in one of the I always hit the Alt key.

• Disable hot keys temporary as mentioned here:

  Can I disable Dash and HUD hotkeys when fullscreen (in DOSBox)?

  or From within Steam, how can I automatically disable the HUD hotkey upon a game's launch, and re-enable it upon that game closing?

• Used different Window Manager while using those app & games. openbox is very light one which does not have any fancy to distract you.

  1. Install it

     sudo apt-get install openbox
     

  2. Launch it

     sudo su
     startx openbox
     

  3. Switching between Unity & Openbox, by default:

     CtrlAltF7 Unity

     CtrlAltF8 Openbox

     but it could be different depending on you setup, you may try from F1 and up.
