In my case with Parrot Linux it was a case of Interrupt conflicts. IRQ#18 kept being disabled by the system. After disabling the EHCI Handoff in the BIOS,ehci_hcd:usb1 was replaced with ehci_hcd:usb2 and the mouse lag after a random period of time stopped.
You can view your interrupt assignments with: cat /proc/interrupts Mine changed from: 18: IO-APIC 18-fasteoi ehci_hcd:usb1, pata_jmicron, ata_piix, uhci_hcd:usb8 to: 18: IO-APIC 18-fasteoi ehci_hcd:usb2, pata_jmicron, ata_piix, uhci_hcd:usb8 And the problem was resolved. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1787857 Title: USB mouse cursor lags after random time of correct behaviour To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1787857/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
