Specifically, I performed the following steps: # Create an xorg.conf file. Xorg -configure cp /root/xorg.conf.new /etc/X11/xorg.conf # Disable input device autodetection by adding the following to # Section "ServerLayout" in the new xorg.conf file: Option "AllowEmptyInput" "Off" Option "AutoAddDevices" "Off" # Install the old default keyboard driver since the new # driver depends on auto-detection. apt-get install xserver-xorg-input-kbd -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to the bug report. https://bugs.launchpad.net/bugs/41301 Title: Mouse clicks stop working sporadically To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/41301/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
