Hi Christian, The install_bcm43xx_firmware command worked perfectly on the one laptop I have tried it on so far. Thank you. How do I install the older kernel and what are the disadvantages to doing so? Does anyone know why that the backlight does not work on intel 4000 series graphics? I have seen some laptops that are getting on a bit now that still do not have support for this. Every single one, the brightness always runs at 100% (which on my laptop is so bright I cannot use it at all, eyes/battery life). On all of the laptops I have tried (5 or 6 different makes/models now) the brightness keys are detected and mapped correctly but a few of them do not show the brightness level at all when pressed. Normally there is a bar that appears just like volume level. Not sure if this is related at all? Paul Groves

Hi all, I have been having a lot of trouble getting opensuse to work with different laptops. The issues I am experiencing also happen with ubuntu so it seems to me to be a kernel issue perhaps?
Every single laptop I have tried that has either of the two following devices has the following issues:
Intel 4000 series graphics - cannot change brightness, always maxed out at 100%!!! (I am unsure if this is the graphics chip or the acpi drivers but would not know how to find out)
The backlight control in some newish laptops do not work well, try with kernel 3.12
Broadcom wifi - does not show in network manager or network settings therefore unusable (does show under device info)
These cards usually require firmware.. did you tried "install_bcm43xx_firmware" as root ?
