I noticed the "DualPoint TouchPad...lost sync" messages in the output of dmesg. I removed "irqpoll" from my kernel command line and rebooted, and mouse movement (via either pointing stick or touchpad) is back to normal. I'm using 32-bit Ubuntu 9.10 (Karmic) on a Dell Latitude D630.
Details: * removed irqpoll from GRUB_CMDLINE_LINUX in /etc/default/grub * ran "sudo update-grub" * rebooted However, I had originally *added* irqpoll because it appeared to fix very slow performance after resuming from sleep ( http://ubuntuforums.org/showthread.php?t=1417770 ), so I'm not sure if that will now be broken again. -- ALPS DualPoint Touchpad flaky performance https://bugs.launchpad.net/bugs/296610 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
