Can you try the following when it works: $ xmodmap -pp > ~/xmodmap-pp $ xev | grep -i button Put the mouse cursor into the rectangle and push your mouse buttons. A left click generates button 1 press and release events and a right click generates button 3 press and release events.
And the following when it fails: $ xmodmap -pp > ~/xmodmap-pp_tmp $ xev | grep -i button Does a left and right click generate the right events? Then run the following command: $ LANG=C diff -ns ~/xmodmap-pp ~/xmodmap-pp_tmp > ~/xmodmap-pp_diff Attach ~/xmodmap-pp, ~/xmodmap-pp_diff and the requested information to the bug report. -- Intermittent mouse flakiness (works on some boots) https://bugs.launchpad.net/bugs/120043 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
