I can return it to proper functioning by removing and replacing the psmouse kernel driver. When I do so, these messages appear in the dmesg log:
[ 1639.710729] psmouse serio2: synaptics: Touchpad model: 1, fw: 7.2, id: 0x1c0b1, caps: 0xd04733/0xa40000/0xa0000 [ 1639.780224] input: SynPS/2 Synaptics TouchPad as /devices/platform/i8042/serio2/input/input10 If it is possible that this is a hardware issue, my hardware is a Dell Inspiron 1750 laptop. I am only aware of this problem affecting the touchpad scroll. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/989981 Title: Scrolling using scroll wheel does not work in certain GTK 3 applications but works elsewhere in 12.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gtk+3.0/+bug/989981/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
