The problem persists under openSUSE 12.1 as described in that bug. You told me to resubmit after testing under 12.1 so here you go. ===== Basically, the Synaptics touchpad driver works fine after reboot, but eventually crashes. The only solution is to reboot or somehow restart the driver. While it is running correctly you get periodic messages in dmesg saying: psmouse.c: TouchPad at isa0060/serio4/input0 lost sync at byte {x} ({x}: the byte number changes) or psmouse.c: TouchPad at isa0060/serio4/input0 lost synchronization, throwing {y} bytes away. ({y}: the byte count changes) When the driver dies the cursor still moves, but the buttons do not work. I have created a BASH script called "fix_pad" to execute the following: modprobe -r synaptics_i2c modprobe synaptics_i2c su andy -c "kcmshell4 synaptiks" This brings up the touchpad settings. I change something (anything: doesn't seem to matter what. Typically I go to the Tapping tab and toggle "Make single taps faster..."), click Apply, click Close, then run fix_pad a second time. About thirty seconds later the touchpad is then revived. I check dmesg when it dies and there is no message other than those cited above. Reproducible: Always Steps to Reproduce: 1.Reboot and use the computer for around an hour 2. Observe the behaviour of the touchpad 3. When the buttons stop working go through the fix_pad routine described above. Actual Results: The touchpad buttons stop working after about an hour. Restarting the synaptics_i2c driver revives the buttons. Expected Results: The driver should not need to be revived in mid-session. It should run reliably. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
