After investigations, it has been found that, while connected through bluetooth, events are received from the mouse every 70ms exactly, explaining the slow move. I was wondering if this could be a driver issue? -- hardware informations - computer: Thinkpad X1 carbon 4th gen (type 20FB) - OS: arch linux - kernel: Linux R2D2-X1 4.9.11-1-ARCH #1 SMP PREEMPT Sun Feb 19 13:45:52 UTC 2017 x86_64 GNU/Linux - lspci -v output: 04:00.0 Network controller: Intel Corporation Wireless 8260 (rev 3a) Subsystem: Intel Corporation Device 0130 Flags: bus master, fast devsel, latency 0, IRQ 133 Memory at e1100000 (64-bit, non-prefetchable) [size=8K] Capabilities: [c8] Power Management version 3 Capabilities: [d0] MSI: Enable+ Count=1/1 Maskable- 64bit+ Capabilities: [40] Express Endpoint, MSI 00 Capabilities: [100] Advanced Error Reporting Capabilities: [140] Device Serial Number XXX Capabilities: [14c] Latency Tolerance Reporting Capabilities: [154] L1 PM Substates Kernel driver in use: iwlwifi Kernel modules: iwlwifi -- You are receiving this mail because: You are the assignee for the bug.-- To unsubscribe from this list: send the line "unsubscribe linux-bluetooth" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
