After boot-up touch screen is working fine, but is generating only "left click" of mouse. This is limiting usage. After some time of usage only "mouse movement" events are generated. Same problem I saw also on Nexus 7 running Ubuntu Desktop. Looks like driver problem, but till now i don't have enough time to debug. | After boot-up touch screen is working fine, but is generating only "left click" of mouse. This is limiting usage.

This page describe problems observed with "HP EliteBook Revolve 810 G1" during regular usage or tests
Contents
Touch Screen
After boot-up touch screen is working fine, but is generating only "left click" of mouse. This is limiting usage. After some time of usage only "mouse movement" events are generated. Same problem I saw also on Nexus 7 running Ubuntu Desktop. Looks like driver problem, but till now i don't have enough time to debug.
Graphics
HW acceleration is working fine. Resolution change, monitor select, etc. is working also fine, but i saw few times artifacts on screen. Looks like GPU is restarting itself at certain moment which cause artifacts to pop up for very short moment. Occurrence is very rare and this is not causing problems.
Wireless
For regular usage WiFi is working fine, but ... When notebook is running on battery power save is high aggressive. For web browsing it is fine, but for interactive sessions (ssh, chat) it is causing visible delay. With power save active also maximal throughput is limited which can affect video on demand.
Power save can be disabled by powertop application or by connecting notebook to AC. Maybe there is way how to disable this permanently ... I'll check it later.
WWAN
Modem is detected by Linux kernel properly and also by Network Manager within Ubuntu. Ubuntu is reporting signal strength correctly but attempt to connect to internet will fail. Looks like modem don't like way how Ubuntu initialize it and as result it reset itself.
Special initialization sequence is necessary prior to connection using network manager
