I have exactly the same problem on my DELL D600. I have been monitoring this page to see if a solution would be created, so I could switch to karmic.
I have experimented a bit with disabling my touchpad using the xinput command, and through removing the appropriate xorg device driver module from the /usr/lib/xorg/modules/input folder. Both the xinput command, and removing the xorg device driver resulted in the same effect. The touchpad and it's buttons were disabled and the behavior of the track stick and it's buttons became better, but the middel mouse button (l+r at the same time) did not work. Also trying to resize a window it appeared that the mouse button only became activated after the movement had started, so the selection happened beside the window. Anyway this appeared not to be the solution. But I think I have found a good solution and I'm curious to know if it works for everybody. The trick seems to be, to change the settings for the mouse pointer in your BIOS: Choose for your "pointing device" the option "PS/2 Mouse", instead of "Touchpad - PS/2 mouse". Despite what you might expect from this, both the track stick and the touchpad work fine under Karmic after this BIOS modification on my DELL D600. -- Mouse behaves strange on clicking in graphical environment https://bugs.launchpad.net/bugs/444674 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
