Hi, Some insights on this.
I'm trying to install Ubuntu on a Packard Bell EasyNote LJ65. This laptop as a GMA4500 M chip. After some research, I saw that from kernel with version above 2.6.38_rc8 (in other words, version of Ubuntu higher than 10.10), a regression did happen causing no backlight on the screen. It's not possible to use the Live CD to try or install since the screen remains black. Some workarounds are available but it'd be good so solve the root cause of this problem. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-power-manager in Ubuntu. https://bugs.launchpad.net/bugs/880096 Title: cant change laptop brightness Status in gnome-power-manager package in Ubuntu: Confirmed Bug description: can`t change laptop brightness, software controls in settings center doesnt have any effect. while typeing on keyboard the status of the screen brightness changes [top right] but aktual brightness does not change. laptop dell vostro 3700.
