I think this is related to https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1883905. I have tried the solutions posted on that bug and at https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1899258
I tried modifying GRUB_CMDLINE_LINUX_DEFAULT for adding several options such as i8042.nopnp=1 i8042.notimeout i8042.reset pci=nocrs etc.. When using windows, the touchpad is recognized as ELAN0733. I am using a brand new HP ProBook 440 G8. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1913768 Title: HP Touchpad Not Detected To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-signed-hwe-5.4/+bug/1913768/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
