Mouse is fully functional, but the mouse cursor is invisible. The problem exists right from boot, i.e. before login.
I can confirm this using kernel 3.19.3, fglrx-installer-15.200, xf86-video-intel-2.20.13, Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09), Advanced Micro Devices, Inc. [AMD/ATI] Whistler [Radeon HD 6730M/6770M/7690M XT], xorg-1.17 server. I have a hybrid graphics device, and I have upgraded enough of my system that downgrading is going to really hurt. If anyone ou there is interested in tackling this, please let me know what kind of data I can provide to help.
I can confirm this issue for Kernel 4.0 and Intel HD Graphics 4400. My graphics software stack is almost current.
