I haven't had any problems with double-clicking on my L380, but can confirm that both touchpad and trackpoint are occasionally become dead (though not necessarily at the same time): Feb 17 11:23:50 l380 kernel: psm0: <PS/2 Mouse> irq 12 on atkbdc0 Feb 17 11:23:50 l380 kernel: psm0: [GIANT-LOCKED] Feb 17 11:23:50 l380 kernel: WARNING: Device "psm" is Giant locked and may be deleted before FreeBSD 15.0. Feb 17 11:23:50 l380 kernel: psm0: model Elantech Touchpad, device ID 0 [...] Mar 8 13:23:12 l380 kernel: psm0: failed to disable the device (psmclose). Mar 8 13:23:13 l380 kernel: psm0: failed to get status (psmclose). Mar 8 13:23:14 l380 kernel: psm0: failed to enable the device (doopen). I've never got around to debug this issue properly as I barely use the laptop without external peripherals. However, the HOOKRESUME flag mentioned in psm(4) gave me the idea to try to "wake" those devices manually by providing them with some I/O immediately after opening the lid, and this little ritual does the job every time I remember to perform it. So it seems like the problem should be somewhere in this area.
