I also own a Thinkpad x121e (AMD E-450) and just for the records: This bug affects me too.
It occured on my device with (X)Ubuntu 12.04 from the last Beta until now . Not using automatic login I can observe the UltraNav (trackpoint and buttons) as well as the touchpad not working immediatly in LightDM . But both input devices come to life after a few seconds. Logging in directly without waiting for these devices to show some reaction the touchpad is working in the desktop environment, but UltraNav stays dead. In opposite to what other users reported my device is not only affected at a few boots from many, but on absolutely every (re)boot. Having a look at dmesg (see attachment) I find my touchpad initialized about 4 seconds after startup: [ 4.070320] psmouse serio4: synaptics: Touchpad model: 1, fw: 8.0, id: 0x1e2b1, caps: 0xd001a3/0x940300/0x123c00 [ 4.070336] psmouse serio4: synaptics: serio: Synaptics pass-through port at isa0060/serio4/input0 [ 4.109971] input: SynPS/2 Synaptics TouchPad as /devices/platform/i8042/serio4/input/input7 But the trackpoint and buttons about 6 seconds later: [ 10.115931] IBM TrackPoint firmware: 0x0e, buttons: 3/3 [ 10.339668] input: TPPS/2 IBM TrackPoint as /devices/platform/i8042/serio4/serio5/input/input9 My x121e is has no default configuration with a common harddisk, but was upgraded with a SSD. And this is my favorite guess why this issue occurs everytime the system is booted here. For some reason the great read times of the disk device resp. the speeded up system boot seem to aggravate the effect of this bug. Well, may be quite helpful for reproduction/debugging to know this… Cannot provide much more information by now. I have no time to investigate the bug any further myself or test several newer kernels. My supposition is the Xserver wether detecting the input device or loading its module way to slow for such boot times. Anyways, I hope this at least helps a little bit. Let me know if you need more information, I will post them as soon as I can spare some time. ** Attachment added: "dmesg log" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/986942/+attachment/3296245/+files/dmesg-986942 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/986942 Title: Trackpoint not work (sometimes after boot) Lenovo Thinkpad X121e 12.04 beta amd64 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/986942/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
