I have same problem with my M510 mouse and K340 keyboard. After 12.04 64bit upgrade to 13.10 64bit - mouse and kbd was very very laggy. Solution for me was:
sudo sh -c 'echo "options drm_kms_helper poll=0" >> /etc/modprobe.d/local.conf' sudo update-initramfs -u for 3.11.0-15-generic x86_64 x86_64 x86_64 GNU/Linux -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1248100 Title: 046d:c52b [ThinkPad L520] Logitech Unified Receiver very laggy To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1248100/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
