I dual-boot Lubuntu (12.04LTS) and Puppy (Studio 3.3, full install) on separate partitions. My Alps touchpad wouldn't work with the supplied Vista (which i ditched) or Linux -- unless, i discovered, i disable ACPI on bootup. In other words, i tried manually editing the boot parameters on startup, adding "acpi=off," and the touchpad worked fine. The next step was to edit grub so that acpi would be switched offf automatically. Since i installed Lubuntu first, grub2 is the bootloader; so i edited /etc/default/grub to read (in part):
- GRUB_CMDLINE_LINUX_DEFAULT="acpi=off quiet splash"
- linux /boot/vmlinuz root=/dev/sda4
While we're at it -- a second, related issue. In Lubuntu, when turning acpi off, my touchpad works and my midi usb cable, but in Puppy, switching off acpi allows my touchpad to work but NOT the midi usb cable.
???!?!?!??!
Thanks for your thoughts....
