Hi Jeroen, Thank you for your questions. Yes, I have. >From my reading understanding the linux kernel consists of a lineage of >patches to the source code.

Again, the bug is described and patched in the following thread. https://bugzilla.kernel.org/show_bug.cgi?id=196129 Supposedly, that patch made it into the mainline kernel v. 4.13.4. I have tried the following: # Get stuff kversion="4.14.2" wget https://kernel.org/pub/linux/kernel/v4.x/linux-$kversion.tar.gz wget https://kernel.org/pub/linux/kernel/v4.x/linux-$kversion.tar.sign zcat linux-$kversion.tar.gz | gpg --verify linux-$kversion.tar.sign - tar xzf linux-$kversion.tar.gz cd linux-$kversion Then configure and compile: make olddefconfig make deb-pkg I also tried: # From: https://github.com/nealk/thinkpad_trackpoint_linuxkernel cp /boot/config-`uname -r` .config yes '' | make oldconfig make clean make -j 3 deb-pkg But then I run out of disk space. I have also tried: make nconfig But then I am overwhelmed with all the new features. So yes, the I failed to compile linux kernel such that it worked. I remember restarting, and then the touchscreen didn't work nor did the keyboard. The DKH (http://kernel-handbook.alioth.debian.org/) gave me a nice schooling, but I am afraid I don't have the time to make it work in the end. Therefore, I ask for help. I guess I should try again starting with the relevant part of the manual (http://kernel-handbook.alioth.debian.org/ch-common-tasks.html#s-common-official). I would if there is a repository of kernel config files specific to computer models and kernel versions. That would be cool and make life a little easier for those that want a custom kernel. Anyways. In the end, I just configure my laptop to turn the screen off upon closing, when I want to keep working shortly afterwards. That's not so bad for use in public transportation. Coding there is kind of fun.
