I think I have a similar problem to this post, but not sure
I was doing some work on my Loki desktop on Sunday but had some kind of issue where everything just seemed to be painfully slow. I rebooted and ever since the windows manager will not respond to mouse clicks. The mouse works, sometimes I can click on the dock items, somethings wingpannel, sometimes both, but oonce I open up an application, I can only control that application with the keyboard. I can't click to select anything in the application window, I can't drag and move the window; nothing. I noticed there is a much longer lag between login and when the pantheon desktop is fully loaded..
I suspect it may have been caused by a faulty update installation. Is there anyway to fix this without a complete re-installation?
I am running Loki on a 2006 Mac Pro desktop 2*Xeon 4-core CPUs 32gb ddr 3 or 2 Nvidia GTX970 EOS is on an SSD
Thanks in advance
I am editing this because I have narrowed the issue down to either 1: the Logitech cordless mouse I was using or 2: clicking on the shutdown icon on wingpannel
