Sorry, this isn't actually a bug. What happens is that on suspend the device is virtually removed and then re-added on resume (as part of the USB shutdown, etc.). In the X server we can't tell the difference why a device was removed (and it may be actually removed after suspend anyway), so we drop the device and add it again later. When it is added again, it's added with the default options. To get your options to stick you should add them to an xorg.conf.d snippet. See this link here for an example: http://fedoraproject.org/wiki/Input_device_configuration#Example:_Wheel_Emulation_.28for_a_Trackpoint.29 Thank for help. I configured wheel emulation via xorg.conf.d snippet. |

Created attachment 109888 [details] Xorg log Good day. I guess that I choice right branch to file a bug. If not please move it to right place. I am using Arch linux based on kernel 3.17.1 on my laptop Lenovo X121e. STEPS TO REPRODUCE: 1. execute the following in terminal: $ xinput set-prop "TPPS/2 IBM TrackPoint" "Evdev Wheel Emulation" 1 $ xinput set-prop "TPPS/2 IBM TrackPoint" "Evdev Wheel Emulation Button" 2 $ xinput set-prop "TPPS/2 IBM TrackPoint" "Evdev Wheel Emulation Timeout" 200 $ xinput set-prop "TPPS/2 IBM TrackPoint" "Evdev Wheel Emulation Axes" 6 7 4 5 So you get a pretty mouse wheel emulation via trackpoint. 2. Suspend to RAM the system. (note: suspend to disk (hibernate) does not lead to bug) 3. Wait couple of seconds. 4. Wake up the system. Expected results: Mouse wheel emulation continue to work. Actual results: Mouse wheel emulation disappeared.
