Created attachment 60626 [details] Xorg log When my finger touch the touchpad, everything is stop. Time is stop, daemon is stop, harddisk is stop... ctrl_alt_bksp also does nothing. The only thing I can do is to press the power button until the screen goes to black with the power light. The last of Xorg.0.log: Backtrace: [461931.870] 0: /usr/bin/X11/X (xorg_backtrace+0x26) [0x7f7c0db0d4d6] [461931.870] 1: /usr/bin/X11/X (0x7f7c0d989000+0x188119) [0x7f7c0db11119] [461931.870] 2: /lib/x86_64-linux-gnu/libpthread.so.0 (0x7f7c0ccb1000+0xf030) [0x7f7c0ccc0030] [461931.870] 3: /usr/bin/X11/X (TimerSet+0x54) [0x7f7c0db0a574] [461931.870] 4: /usr/lib/xorg/modules/input/synaptics_drv.so (0x7f7c01fdc000+0x53f7) [0x7f7c01fe13f7] [461931.870] 5: /usr/bin/X11/X (0x7f7c0d989000+0x8a947) [0x7f7c0da13947] No more log, maybe because everything is stop.
Can you try synaptics 1.5.99.904? It has an important time-related fix that may be the cause for this issue too.

This is a mass change of bugs. Bugs assigned to me that haven't been updated in the last 3 years are closed as WONTFIX, because, well, let's at least be honest about it. Please do not re-open unless you have a really good reason to do so (e.g. you're fixing it yourself). If it hasn't been fixed in the last 3 years, it probably won't be fixed anytime soon either. Sorry.
