I just updated to Ubuntu 12.04 from 11.10 but soon after updating I was disappointed to see that
Wireless is disabled by hardware switch.
I can not click the button 'Enable wireless' which is greyed out. Without wireless my computer is useless as I have to connect by wire which is not practical. I have a Acer TravelMate 4500
I've tried do undo this but not able to get it disabled. My sound settings need to be redone every boot up as well, but asking that question as well would get neg. feedback.
I didn't install anything myself, but only Ubuntu 12.04 LTS on an Acer 4741g.
I use Fn+left/right to change the brightness, but failed.
How can I control the brightness levels?
I have Dolby Virtual Surround Sound 5.1 speakers with Tuba CineBass Subwoofer on Acer laptop (mine is 5951G but there is also bunch of models with similar configuration of speakers with/without subwoofer). In Windows it works and sounds amazingly after installing both Realtek drivers and Dolby software from Acer support site. In Ubuntu only 2-channel sound is working.
How can I enable virtual 5.1 sound or at least subwoofer?
I listen to music almost any time I am on my computer. I often accidentally unplug my headphones. This has resulted in disturbing others around me. Does any one know of a way to mute the speakers (and potentiality pause VLC) when headphones are unplugged?
I would like to do this on my Laptop. It is an Acer Aspire One D150. The speakers are built-in to the computer. My headphones are standard 1/8 in which connect through the headphone jack.
