Hardware: HP EliteBook Revolve 810 G1 with Ubuntu Linux - problems
This page describe problems observed with "HP EliteBook Revolve 810 G1" during regular usage or tests.
Contents
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.
I am currently running 14.04.01 LTS and it looks like this problem is gone.
Wireless
For regular usage WiFi is working fine, but ... When notebook is running on battery power save is highly 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. Alternatively you can use:
sudo iwconfig wlan0 power off
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.
I am currently running 14.04.01 LTS and it looks like this problem is gone.
GPS
Till now I don't have time/need to test GPS. I may check this during summer ...
