So I patched the 4.15.0-15-generic kernel from kernel.ubuntu.com with the supplied patch and then intstalled the kernel on my 16.04 xenail laptop and everything works as it should. The display came up, the touch pad is responsive and working normally. I have enclosed my dumps of lswh, lspci, lsmod and my cmdline output.
How I installed this: I build a bionic container on my laptop: lxc launch ubuntu-daily:bionic kernel lxc file push spth-pinctrl-fix.diff kernel/root/ lxc exec kernel bash apt update && apt upgrade -y apt build-dep linux-image-`uname -r` apt install fakeroot git clone git://kernel.ubuntu.com/ubuntu/ubuntu-bionic.git cd ubuntu-bionic cp ../spth-pinctrl-fix.diff . patch -p1 < spth-pintctrl-fix.diff fakeroot debian/rules clean fakeroot debian/rules binary-headers binary-generic binary-perarch After the build and the output of the deb files: exit mkdir ~/kernel-test cd ~/kernel-test lxc file pull kernel/root/linux-image-4.15.0-15-generic_4.15.0-15.16_amd64.deb . lxc file pull kernel/root/linux-image-extra-4.15.0-15-generic_4.15.0-15.16_amd64.deb . lxc file pull kernel/root/linux-headers-4.15.0-15_4.15.0-15.16_all.deb . lxc file pull kernel/root/linux-headers-4.15.0-15-generic_4.15.0-15.16_amd64.deb . Also, the linux-headers-4.15.0-15 deb depends on libssl1.1, which is default in Bionic, but not in Xenial, so I had to download that deb file from here: https://packages.ubuntu.com/bionic/libssl1.1 And then I just used dpkg -i to install the files and reboot the laptop and it started up properly. While the laptop display works and the touchpad is responsive and works properly. there are still issues with the FN+F7/F8 brightness controls, and the other FN options that should work out of the box, but at least the display works with the 4.15.0-15 kernel ** Attachment added: "logs.tar.gz" https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-390/+bug/1761261/+attachment/5125965/+files/logs.tar.gz -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-nouveau in Ubuntu. https://bugs.launchpad.net/bugs/1761261 Title: nouveau/nvidia drivers do not work with display in Bionic on Asus GL703VD Laptop To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-390/+bug/1761261/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : email@example.com Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
