First if all thank you Lukas, for pinpointing the problem. I don't see any really obvious nice answer here.
So I believe it is best to override the IRQ type manually in the AMD gpio driver to correct the acpi_get_override_irq() results from the ACPI core. I've attached a patch doing this to bug 199523. If someone who is seeing this issue can build and test a kernel with that patch (replacing Lukas patch) that would be great. To be clear please drop Lukas' patch when testing mine! If you test my patch, please provide the output of "dmesg" directly after boot and let me know if the patch fixes things (makes/keeps the touchscreen working). -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1752437 Title: [HP ENVY x360 - 15-bq102ng] Touchscreen does not work Status in linux: Confirmed Status in linux package in Ubuntu: Confirmed Bug description: The touch screen on my HP ENVY x360 15-bq102ng does not work with stock kernel or with mainline kernel 4.16-rc3. marc@snapbug:~$ xinput ⎡ Virtual core pointer id=2 [master pointer (3)] ⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)] ⎜ ↳ SynPS/2 Synaptics TouchPad id=13 [slave pointer (2)] ⎣ Virtual core keyboard id=3 [master keyboard (2)] ↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)] ↳ Power Button id=6 [slave keyboard (3)] ↳ Video Bus id=7 [slave keyboard (3)] ↳ Video Bus id=8 [slave keyboard (3)] ↳ Power Button id=9 [slave keyboard (3)] ↳ AT Translated Set 2 keyboard id=12 [slave keyboard (3)] ↳ HP Wireless hotkeys id=14 [slave keyboard (3)] ↳ HP WMI hotkeys id=15 [slave keyboard (3)] ↳ HP Wide Vision FHD Camera: HP I id=11 [slave keyboard (3)] ↳ HP Wide Vision FHD Camera: HP W id=10 [slave keyboard (3)] WORKAROUND: Use the following patch with 4.17-rc3: https://bugzilla.kernel.org/attachment.cgi?id=275381 ProblemType: Bug DistroRelease: Ubuntu 17.10 Package: xorg 1:7.7+19ubuntu3 Uname: Linux 4.16.0-041600rc2-generic x86_64 ApportVersion: 2.20.7-0ubuntu3.7 Architecture: amd64 BootLog: No key available with this passphrase. /dev/mapper/nvme0n1p2_crypt: clean, 621596/15597568 files, 54013381/62389248 blocks CompizPlugins: No value set for `/apps/compiz-1/general/screen0/options/active_plugins' CompositorRunning: None CurrentDesktop: ubuntu:GNOME Date: Wed Feb 28 22:34:50 2018 DistUpgraded: Fresh install DistroCodename: artful DistroVariant: ubuntu ExtraDebuggingInterest: Yes GraphicsCard: Advanced Micro Devices, Inc.
