http://ubuntuforums.org – Hi all; FYI, Dell e5510 laptop with I915 graphics. Updated to the latest kernel (3.0.0-15) and the onboard lcd ( eDP1) stopped working. reboot with 3.0.0-13 and everything is cool again. In order to select previous kernel edit /etc/default/grub change the line that has; GRUB_HIDDEN_TIMEOUT=0 to something like GRUB_HIDDEN_TIMEOUT=10 then sudo update-grub when you reboot you will have 10 seconds to chose an older kernel HTH Pat (Hardware)
