Bug Description
Binary package hint: hal-info
Hello,
I am using the Jaunty beta with today's (04/14) updates. Some of my laptop hotkeys such as increase/decrease display brightness, toogle WLAN on/off, select video output and some less important Samsung specific do not work. I followed the guide at https:/
FN+F4: toogle video output (LCD, external connector)
EV_MSC code=4 value=130
EV_SYN code=0 value=0
FN+F5: switch LCD backlight on/off
EV_MSC code=4 value=132
EV_SYN code=0 value=0
FN+F9: switch WLAN on/off
EV_MSC code=4 value=134
EV_SYN code=0 value=0
FN+Key up: increase LCD brightness
EV_MSC code=4 value=136
EV_SYN code=0 value=0
FN+Key down: decrease LCD brightness
EV_MSC code=4 value=137
EV_SYN code=0 value=0
The FN+Esc keystroke is intended to activate standby mode. This does not work; the laptop is actually going standby but the LCD stays off when woken up again (however, pressing the power button shuts it safely down). Suspend and resume via software works fine.
There are some more Samsung (and Windows) specific FN-keystrokes such as
FN+F2: show battery state
EV_MSC code=4 value=131
EV_SYN code=0 value=0
FN+F7: run some PC doctor intended for system recovery
EV_MSC code=4 value=177
EV_SYN code=0 value=0
FN+F8: toogle CPU frequency states: powersave, normal, performance (Samsung applet in Windows)
EV_MSC code=4 value=179
EV_SYN code=0 value=0
I also appended the log files as wished in the hotkeys page. Sorry if I forgot something, I'm quite new to bug reporting :)
Cheers,
Stefan
I have exactly the same problems.
When I try to use brightness keys seems that ubuntu "understands" what I'm doing, because on the top-right of the screen appears the brightness bar (like the volume one, when I change the volume) but it is "blocked".
I have to add that it's possible to increase/decrease brightness using "brightness applet" but only if the nvidia drivers are disabled.
I hope it can help.
thanks,
Stefano
