Sudo apt-get upgradeOnce the upgrade is complete, restart the laptop. there’s no levels and now i’m seeing it turn on in a wave and then sometimes turn off and i have to close my lid to start it again. my screen brightness now the down turn the screen bright.
Sudo add-apt-repository ppa:canonical-hwe-team/sputnik-kernel I have a dell latitude d610 my screen does not work properly so i tried to replace it. To add the Sputnik Kernel PPA in Ubuntu 12.04 Precise Pangolin or 12.10 Quantal Quetzal and upgrade the Linux Kernel, use the following commands: Install the Sputnik Kernel in Ubuntu 12.04 or 12.10 To fix it manually, run the following commands in a terminal: echo '#fix dell wifi/bluetooth:' | sudo tee -a /etc/modprobe.d/nfĮcho 'blacklist dell_laptop' | sudo tee -a /etc/modprobe.d/nfThen, restart the laptop and the WiFi / Bluetooth should work normally. Besides the issues above, there was another issue which caused Dell XPS 13 and Dell XPS 15 WiFi to be disabled when disabling the Bluetooth (and the other way around) that was fixed both into the kernel available in this PPA and in the Ubuntu 12.04 kernel, but apparently it wasn't fixed for Dell XPS 17 laptops too.
