Comment 22 for bug 1159707

Same problem on Ubuntu 15.04 64 bit on a Lenovo W550s with the default configuration and with nvidia-346 and nvidia-prime installed. The Cinnamon version is 2.2.16-5.

The panel and all the applets inside the panel do not react at all - it is as if the panel was simply not there: right clicking on the panel brings up the same menu as when right clicking on the desktop.
However, starting programs from desktop icons works and the program windows are responsive, switching with Alt-Tab between them works too. The Menu can be opened using the Win key and then works as it should. However, because the window list in the panel and the other elements of the panel are not usable with the mouse, Cinnamon is practically useless for me. Which is a pity because it is the only window manager that seems to correctly deal with the HiDPI of the Lenovo W550s.

Is there any way how we could provide additional information that may help to get this bug fixed?
