Comment 10 for bug 934189

I am also affected. No global hotkey works after I closed all open windows except conky. Contrary all hotkeys do work right after login. Once all windows are closed, I have to click conky to regain global hotkey access.

I am using LightDM and Gnome's fallback mode with Compiz, thus no unity.

Hardware/System:
Lenovo Thinkpad T410i
NVIDIA Corporation GT218 [NVS 3100M]
Ubuntu 12.04.2 LTS (precise)

Relevant packages:
compiz 1:0.9.7.12-0ubuntu1
conky 1.8.1-6
gnome-session-fallback 3.2.1-0ubuntu8
lightdm 1.2.3-0ubuntu2.1
linux-image-generic-lts-quantal 3.5.0.32.39
nvidia-current 304.88-0ubuntu0.0.2
xorg 1:7.6+12ubuntu2
xserver-xorg-core-lts-quantal 2:1.13.0-0ubuntu6.1~precise3
xserver-xorg-lts-quantal 1:7.7+1ubuntu4~precise1

Conky is set up as follows:
own_window yes
own_window_argb_visual yes
own_window_class conky
own_window_hints undecorated,below,sticky,skip_taskbar,skip_pager
own_window_transparent yes
own_window_type normal
