I do, indeed, see how the discrete card is turned off thanks to you
pol@lunabox:~$ lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation Core Processor
Integrated Graphics Controller (rev 02)
01:00.0 VGA compatible controller: ATI Technologies Inc Manhattan
[Mobility Radeon HD 5000 Series] (rev ff)
Until you said that Rev(ff) means it's turned off, I wasn't able to
check if it really was off, mainly because when I check the battery
state I get a lot of 'unknown' fields:
pol@lunabox:~$ cat /proc/acpi/battery/BAT0/state
present: yes
capacity state: ok
charging state: discharging
present rate: unknown
remaining capacity: 3369 mAh
present voltage: unknown
Also, I checked the switch-between-cards script but I always get
both of them ON, and trying to turn them OFF does nothing but show a
notification (if I re-run the script it shows both ON again).
As a project for my studies I am -sort of- developing a tool to
switch between cards using the acpi_call method but graphically as
Windows boxes do.
Keep us updated on that one please, I am sure there is a huge
interest for something like that
