Okay, just went back over some things to confirm in case anyone else is encountering this issue. First, here's my setup:
1. Lenovo 330s-15arr with BIOS version 7WCN28WW. 2. BIOS settings are default for the most part (UEFI boot, etc). With the above BIOS version, booting into Ubuntu with noapic line hoses the keyboard and it will not work again (even in the BIOS!) until the system has been booted into Windows. After booting into Windows, this seems to "reset" something on the keyboard. USB keyboard/mouse works fine though, so you can diagnose/fix this issue with that if you don't have dual boot configured. Per Kenji's instructions above, edited /etc/default/grub and added ivrs_ioapic[32]=00:14.0 to the grub cmds, ran update-grub and now everything boots with the following to be confirmed working: 1. Wireless (including 5ghz), 2. Bluetooth, 3. Keyboard, including hotkeys in Fn+Hotkey setup (this is a toggle in the BIOS I prefer), 4. Touchpad, including multi touch scrolling and two finger tap for context menu, 5. Graphics acceleration, tested with glxinfo and glmark2. To really drive this home, I am about to attempt a reinstall from scratch blowing away Windows. On the installer boot line, I will be adding the above ivrs_ioapic as well to ensure installer has proper resource access. This will make double sure I don't have some other customization out there helping with this. Will report back soon. -- 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/1795292 Title: ELAN469D touch pad not working Status in Linux: Confirmed Status in linux package in Ubuntu: Confirmed Bug description: I installed Bionic Beaver and now upgraded to Cosmic Cuttlefish on this Lenovo Ideapad 330S-15ARR laptop.
