backlight

I installed Ubuntu (12.04) on my acer aspire 5734z and the back light stopped working. I have tried the fix by editing the grub file posted on here a couple of days ago but that hasn't fixed it. I have also looked for hardware drivers but that didn't get me anywhere. When I hook up an external monitor it works fine but i have been unsuccessful getting the laptop display to light up.

Thanks

I found a fix here " http://crunchbanglinux.org/forums/post/66562/#p66562 " if anyone has a better fix than the one in that post, let me know.

Will final version of 12.04 use the power management changes found in kernel 3.3

I have seen in some version of Ubuntu that instead of making a huge change to update to the latest kernel, they take some of the good stuff out of it, for the sake of stability and put it on a previous version. In this case, kernel 3.3 has seen some very good power management enhancements that are… >>> More
