I hope this helps.Įdit: some more things come to mind, which can be worth trying:ġ) Make sure that you have an encompassing repository list /etc/apt/sources.list such as the one shown here, run apt-get update, install the package firmware-linux, reboot and see if the problem still exists.Ģ) Update your BIOS to the latest version, reboot and see if the problem persists.ģ) Log in to your BIOS and change all settings of "energy saving" stuff to "off" (or enable maximum performance), reboot and check it again.Ĥ) Find out your touchpad brand and model and search for issues related or drives available for Linux. Disassemble your laptop, find the hardware switch that is triggered when closing the lid and "defeat" it. If it works, then this could be the workaround itself, or you can start building up from this point (ex: try "blank the screen" next) until it stops working.Ģ) Disable the hardware switch: this one is the "dirty", last ditch approach. It is not Debian's fault - some of those laptops have a hardware switch for the screen that (sometimes) does not only informs the OS about the closing screen but also executes "commands" via firmware (not controlled by the OS), some of which "commands" could be turning off the mousepad, etc.ġ) "Do nothing" when lid is closed: I don't know what desktop you are using, but most desktops give you the option of controlling which action to take when you close your lid choose "do nothing" if possible (don't even blank the screen), reboot the computer and try again. Start by going into Settings and selecting Mouse & Touchpad. That said, there are a few other options you may need to check. Most of the time, the way to fix a touchpad not working in Linux is to simply install or update drivers. Weird things can happen when you close and open your lid on a laptop that did not have Debian originally installed. In some cases, you may need to install another driver package like xserver-xorg-input-synaptics.
