After some experimenting. Disabling usbhid/hid and using usbkbd/usbmouse did not help. When problem occurred, there was no info in ~/.xsession-errors or the Xorg log file or dmesg.
While the problem was occurring, unplugging the USB keyboard and plugging it back in, or loading/unloading hid/usbhid did not halt the error. I suspect then the flaw is in X - in keyboard repeat I guess. Holding down the key while clicking on mouse befuddles its simple brain? Will look for similar X errors. -- Erratic keyboard repeat https://bugs.launchpad.net/bugs/55843 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
