I think that thanks to Gentoo wiki and LinuxQuestions I have found a workaround.
The problem seems to be in touchpad detection for the first time psmouse module is loaded. Usually (but what is strange - not always) dmesg says something like: [ 24.992320] input: PS/2 ALPS GlidePoint as /devices/platform/i8042/serio1/input/input10 and it's wrong, it should be something like: [ 191.276394] input: AlpsPS/2 ALPS GlidePoint as /devices/platform/i8042/serio1/input/input15 The difference in "PS/2 ALPS GlidePoint" and "AlpsPS/2 ALPS GlidePoint" is the most important. When dmesg shows no "Alps" in front of "PS/2" thouchpad is not being recognized by XServer, when there is this "Alps" in front of "PS/2" - touchpad works as it should. The workaround for this problem is reloading psmouse module - I checked few times and loading psmouse module 2nd time always makes touchpad being detected properly. Just to check if it works for you too do this: sudo rmmod psmouse && sudo modprobe psmouse and restart XServer (Ctrl+Alt+Backspace). To reload psmouse module automatically on each boot place these 2 lines in /etc/rc.local file (before the "exit 0" line): /sbin/rmmod psmouse /sbin/modprobe psmouse This works for me on Dell XPS M1530. -- Synaptics touchpad not detected https://bugs.launchpad.net/bugs/191024 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
