Hi Ferenc. Tried your method. In /tmp/dsdt.dsl I found the HID of the touchpad: 0633 (!)
If ((TPTY == One)) { _HID = "ELAN0633" BADR = 0x15 HID2 = One Return (Zero) } But then there is no "TPVD" to be found in the whole file. When searching for "_STA" I find Method (_STA, 0, NotSerialized) // _STA: Status { If ((TPTY == Zero)) { Return (Zero) } Else { Return (0x0F) } } Can you please help? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1861610 Title: 'Elan touchpad' not detected on 'Lenovo ThinkBook 15 IIL' To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1861610/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
