We tried below step in several netbook 1.adjust the time to backward and apply 2.move the cursor via touchpad We found cursor can't be moved, the touchpad is locked. If we restart Xorg, it may work well then. Do you have any clue about this issue? thanks!
I cannot reproduce this issue with X server 1.9.99.1, synaptics 1.3.99 and kernel 2.6.37-rc3, so it's likely something that has already been fixed upstream. Please test with upstream versions of the X server, synaptics driver and kernel before reporting bugs here.
We found if kill syndaemon process, this bug will not be reproduced. Keep investigating it
oh, that makes sense then. syndaemon has a simple condition: if (current_time > last_activity + idle_time) /* Enable touchpad */ if you move the current time backwards, it will not time out as usual and thus keep the touchpad disabled. I wouldn't count this as a bug though.
Created attachment 40653 [details] [review] TimeBackwardSetting.patch
In back set time situation, reassgin current_time and last time. Testing in my netbook, this bug has been fixed. Please check it.
