Hi All:

I too am experiencing this issue on Dell Laptops.  Can't type or click after unlock with Firefox left open.  Close browser and then it will work.  Did not try to just minimize and then click or type. Will try this next time it happens.

Thanks...

P.S. Also am experiencing the bug where I have to lock the screen before sleep (closing of laptop lid) or will be greeted by black screen after resume and unlock.

Try:

Code:

sudo apt-get install acpi-support

then reboot, see if it still happens.
