CID: 201409-15477 Dell Latitude
With nvidia proprietary driver installed, I can switch from nvidia GPU to Intel GPU with "NVIDIA X Server Settings" tool, just change the setting there and log out.
However, if you try to switch from nvidia GPU to Intel GPU, and log out, it will drop into low-graphic mode.
(It works fine if you reboot it)
Error message can be found in the xorg log:
[ 177.997] Markers: (--) probed, (**) from config file, (==) default setting,
(++) from command line, (!!) notice, (II) informational,
(WW) warning, (EE) error, (NI) not implemented, (??) unknown.
