I had this problem on a PowerPC Mac Powerbook G4 using a Logitech USB mouse, but the addition of "CorePointer" to xorg.conf as described above fixed it. Thank you!! It was driving me crazy. Not every single click was interpreted as a double click, but nearly every one.
It was an upgrade some weeks ago on 8.04 that introduced the problem. The graphics card on this machine refreshes fairly slowly, and I wondered if this might have something to do with it - long periods with interrupts disabled, for example. -- single click is considered as double click https://bugs.launchpad.net/bugs/196711 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
