Comment 0 for bug 808384

When I press the button Fn and button F3/F4/F5 to control the volume on laptop.

The volume level notification flickers a long time without control and the desktop hangs for a while.

After, turns into normality and "dmesg" shows [drm:drm_mode_getfb] *ERROR* invalid framebuffer id
