Thanks for the bug report. Firstly, if you have 'tlp' installed then please uninstall it because it can cause problems like this.
Secondly, you mention 'Microsoft' and 'Trust' mice in the bug description but your logs only ever seem to show: * Logitech USB Optical Mouse * Sunplus Innovation Technology Inc. Optical Mouse So I would like to understand which is the one you call the 'Trust' mouse. While the 'Trust' mouse is plugged in, please run: lsusb > lsusb2.txt and attach the resulting text file here. ** Package changed: xorg (Ubuntu) => linux (Ubuntu) ** Changed in: linux (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1915704 Title: Specific pointing device disappear/disconnect when standby To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1915704/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
