Dmitry, Many thanks for your questions. With factory installed Windows 8, TouchPad works. However, I run Ubuntu and have never had working TouchPad with Ubuntu (from 3.13 kernel now up to 4.2). Is there a way to check if my TouchPad key is ON/OFF? Solutions I have tried unsuccessfully: Keypad solutions: F5 Fn+F5 pressing NumLock repeatedly during boot Modprobe solutions: sudo modprobe -r psmouse && sudo modprobe psmouse sudo modprobe -r psmouse && sudo modprobe psmouse proto=imps sudo modprobe -r psmouse && sudo modprobe psmouse proto=exps Kernel solutions (append to grub at end of quiet splash line): atkbd.reset i8042.nomux i8042.nopnp i8042.reset=1 Missing Package solutions: sudo apt-get install xserver-xorg-input-synaptics sudo apt-get install gpointing-device-settings I believe it is for these reasons that I was referred to kernel listserv. If you have other thoughts or need more information, please let me know! jtd Dmitry Torokhov: > On Wed, Sep 9, 2015 at 7:40 AM, jtd <jtdjtdjtd.business@xxxxxxxxx> wrote: >> [1.] >> [Toshiba Satellite P855-S5102] SynPS/2 Synaptics TouchPad Dead >> >> [2.] >> I expect a mouse.
