Title:
Dell XPS 13 (haswell) touchscreen works only after suspend-wakeup
cycle on BATTERY (no AC)
Status in “linux” package in Ubuntu:
In Progress
Bug description:
The touchscreen (ID 06cb:0af8 Synaptics, Inc. ) on the Dell XPS 13
only works after the computer has been:
1. Unplugged from AC so it runs on battery
2. Suspended to Ram
3. Woken up from Ram
it will only work on battery, if plugged into AC the touch screen will
not work even after the suspend-wakeup cycle.
On login I get the notice that no touchpad has been found and I cannot
find and configure a touchpad in the settings (for multitouch,
scrolling etc), is the touchscreen and touchpad the same device as far
as the OS is concerned?
