My instance (INCLUDES WORKAROUND): HP Pavilion dv7-6175us (model LW172UA#ABA) Ubuntu 12.04 x86_64 Kernel 3.2.0-21-generic #34-Ubuntu
After sleep (pm-suspend), messages appear when typing (probably when touching keyboard or touchpad): kernel: [ t ] psmouse serio1: TouchPad at isa0060/serio1/input0 lost sync at byte 4 kernel: [ t + ~3ms] psmouse serio1: TouchPad at isa0060/serio1/input0 lost sync at byte 1 kernel: [ t + ~5ms] psmouse serio1: TouchPad at isa0060/serio1/input0 lost sync at byte 1 kernel: [ t + ~8ms] psmouse serio1: TouchPad at isa0060/serio1/input0 lost sync at byte 1 kernel: [ t + ~9ms] psmouse serio1: TouchPad at isa0060/serio1/input0 lost sync at byte 1 kernel: [ t + ~9ms] psmouse serio1: issuing resync request ... kernel: [ u ] psmouse serio1: TouchPad at isa0060/serio1/input0 lost sync at byte 1 kernel: [ u + ~2ms] psmouse serio1: TouchPad at isa0060/serio1/input0 lost sync at byte 1 kernel: [ u + ~12ms] psmouse serio1: TouchPad at isa0060/serio1/input0 - driver resynced. ... [sets similar to these repeat as I use the keyboard & touchpad] While this is going on, keyboard input may miss some make- or break- strokes. Worked around this by doing: $ sudo rmmod psmouse; sudo insmod /lib/modules/$(uname -r)/kernel/drivers/input/mouse/psmouse.ko resulting in: kernel: [ v ] psmouse serio1: synaptics: TouchPad model: 1, fw: 7.5, id: 0x1e0b1, caps: 0xd00073/0x240000/0xa0400 kernel: [ v + ~52ms ] input: SynPS/2 Synaptics TouchPad as /devices/platform/i8042/serio1/input/input15 Note that `modprobe psmouse` does not work, it apparently won't notice the presence of the hardware ??? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/366261 Title: Synaptic touchpad lost sync when switch keyboard layouts To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-input-synaptics/+bug/366261/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
