The touchpad doesn't work in installer on Lenovo G50, whereas it works with gpm in "rescue" from alt-8.0.0-20160629-server-x86_64-ru-install-dvd5.iso (and alt-workstation-20160627-x86_64.iso after gpm is installed).

Some grep results; the difference between the case when it works and doesn't work is one line (with LIBINPUT_MODEL_SYNAPTICS_SERIAL_TOUCHPAD=1):

$ fgrep -i touch udevadm-info-exportdb-touchpadworks.txt
E: ID_INPUT_TOUCHPAD=1
E: ID_INPUT_TOUCHSCREEN=1
E: NAME="SynPS/2 Synaptics TouchPad"
E: ID_INPUT_TOUCHPAD=1
E: ID_INPUT_TOUCHSCREEN=1

Here is the whole related block when it works and when it doesn't (I'm not sure whether this is the block that is important):

На свежесобранном education-20160823-x86_64.iso LiveCD помогло добавление пакета xorg-drv-libinput по совету shrek@.

Просьба проверить на сентябрьских выпусках workstation/starterkits, добавил.
