evdev doesn't have any disable-while-typing mechanism and if you say syndaemon isn't running I'm not sure what happens here. Either way syndaemon shouldn't affect USB mice anyway. Run xinput watch-props "device name" on the mouse and the touchpad and see if any of the properties change when you use the keyboard. Both $ xinput watch-props 'ALP000D:00 044E:120C' and $ xinput watch-props 'AlpsPS/2 ALPS GlidePoint' does not show any changes when I type, even if the touchpad clearly becomes blocked. However, at the moment my external mouse is actually no longer blocked. Could this be related to the fact that I only plugged it in later? run evemu-record on the kernel device for the touchpad (and/or mouse) and see if it blocks there too - if so, it's a bug in the kernel. I don't quite understand. You mean the mere act of running 'evemu-record' could prevent the blocking? If not, then what do you mean with "if it blocks there too". $ sudo evemu-record /dev/input/event17 Shows prints something whenever I use the touchpad, but there is no change when I start (or stop) typing on the keyboard, what I meant was: if you look at the touchpad device with evemu, do the events stop when you start typing? If so then the issue is in the hardware or the kernel. If you still see events from the touchpad while typing, then the issue is in userspace somewhere. Ah, got it. Yes, when I am typing (and up to about 1 second after stopping), 'evemu-record' does not show any events for the touchpad. Do you have any suggestion where I could start to track this down in the kernel? It's weird, it very much looks like a deliberate feature... libinput sees the same events as evemu does, so there isn't much we can do. I suspect this is due to the device not being in proper touchpad mode and the firmware implementing some disable-while-typing. Let's track this in bug #100345. |

Whenever I type something on my (internal) keyboard, and then attempt to use my external, USB mouse I have to wait about a second until the mouse responds. The touchpad is blocked as well, but that is probably a feature. I do *not* have syndaemon running. xinput says: $ xinput ⎡ Virtual core pointer id=2 [master pointer (3)] ⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)] ⎜ ↳ ALP000D:00 044E:120C id=10 [slave pointer (2)] ⎜ ↳ AlpsPS/2 ALPS GlidePoint id=12 [slave pointer (2)] ⎜ ↳ Chicony Wireless Device id=16 [slave pointer (2)] ⎜ ↳ Chicony Wireless Device id=17 [slave pointer (2)] ⎣ Virtual core keyboard id=3 [master keyboard (2)] ↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)] ↳ Power Button id=6 [slave keyboard (3)] ↳ Video Bus id=7 [slave keyboard (3)] ↳ Sleep Button id=8 [slave keyboard (3)] ↳ HP HD Camera id=9 [slave keyboard (3)] ↳ AT Translated Set 2 keyboard id=11 [slave keyboard (3)] ↳ HP Wireless hotkeys id=13 [slave keyboard (3)] ↳ HP WMI hotkeys id=14 [slave keyboard (3)] ↳ Chicony Wireless Device id=15 [slave keyboard (3)] $ xinput --list-props 16 Device 'Chicony Wireless Device': Device Enabled (139): 1 Coordinate Transformation Matrix (141): 1.000000, 0.000000, 0.000000, 0.000000, 1.000000, 0.000000, 0.000000, 0.000000, 1.000000 Device Accel Profile (262): 0 Device Accel Constant Deceleration (263): 1.000000 Device Accel Adaptive Deceleration (264): 1.000000 Device Accel Velocity Scaling (265): 10.000000 Device Product ID (257): 1266, 2422 Device Node (258): "/dev/input/event18" Evdev Axis Inversion (266): 0, 0 Evdev Axes Swap (268): 0 Axis Labels (269): "Rel X" (149), "Rel Y" (150), "Rel Horiz Wheel" (492) Button Labels (270): "Button 0" (506), "Button Unknown" (260), "Button Unknown" (260), "Button Wheel Up" (145), "Button Wheel Down" (146), "Button Horiz Wheel Left" (147), "Button Horiz Wheel Right" (148) Evdev Scrolling Distance (271): 1, 1, 1 Evdev Middle Button Emulation (272): 0 Evdev Middle Button Timeout (273): 50 Evdev Third Button Emulation (274): 0 Evdev Third Button Emulation Timeout (275): 1000 Evdev Third Button Emulation Button (276): 3 Evdev Third Button Emulation Threshold (277): 20 Evdev Wheel Emulation (278): 0 Evdev Wheel Emulation Axes (279): 0, 0, 4, 5 Evdev Wheel Emulation Inertia (280): 10 Evdev Wheel Emulation Timeout (281): 200 Evdev Wheel Emulation Button (282): 4 Evdev Drag Lock Buttons (283): 0 $ xinput --list-props 17 Device 'Chicony Wireless Device': Device Enabled (139): 1 Coordinate Transformation Matrix (141): 1.000000, 0.000000, 0.000000, 0.000000, 1.000000, 0.000000, 0.000000, 0.000000, 1.000000 Device Accel Profile (262): 0 Device Accel Constant Deceleration (263): 1.000000 Device Accel Adaptive Deceleration (264): 1.000000 Device Accel Velocity Scaling (265): 10.000000 Device Product ID (257): 1266, 2422 Device Node (258): "/dev/input/event19" Evdev Axis Inversion (266): 0, 0 Evdev Axes Swap (268): 0 Axis Labels (269): "Rel X" (149), "Rel Y" (150), "Rel Vert Wheel" (261) Button Labels (270): "Button Left" (142), "Button Middle" (143), "Button Right" (144), "Button Wheel Up" (145), "Button Wheel Down" (146), "Button Horiz Wheel Left" (147), "Button Horiz Wheel Right" (148) Evdev Scrolling Distance (271): 1, 1, 1 Evdev Middle Button Emulation (272): 0 Evdev Middle Button Timeout (273): 50 Evdev Third Button Emulation (274): 0 Evdev Third Button Emulation Timeout (275): 1000 Evdev Third Button Emulation Button (276): 3 Evdev Third Button Emulation Threshold (277): 20 Evdev Wheel Emulation (278): 0 Evdev Wheel Emulation Axes (279): 0, 0, 4, 5 Evdev Wheel Emulation Inertia (280): 10 Evdev Wheel Emulation Timeout (281): 200 Evdev Wheel Emulation Button (282): 4 Evdev Drag Lock Buttons (283): 0 Both the Chicony devices disappear when I disconnect the external mouse.
