I can concur this on Dell D600, both stick buttons and touchpad buttons seem to miss ButtonPress and Button release event's on random starting with 9.10 release. No such problems on 9.04 or any of the previous releases.
This is also easy to replicate on 9.10 Desktop 32-bit installation Live-CD: boot from cd, open terminal, launch xev from the terminal, activate xev window and start clicking on it while mouse cursor is on the xev window. On the terminal you should see a ButtonPress and ButtonRelease event for every click, but randomly either one could be missing. Result is mis-interpreted click-holds, etc. -- 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
