    Re: Dell XPS 13 ultrabook compatibility

    Thought I'd drop another note here. Dmesg says the trackpad is ImPS/2:

    Code:
    [    3.258400] input: ImPS/2 Generic Wheel Mouse as /devices/platform/i8042/serio1/input/input11
    Anyone know what kind of trackpad it really is and how to have it detect the right driver? I'm guessing that will fix up the touchpad scrolling issues.

    Yes, that's the one.

    Install was clean. 12.04 beta was touchy, so I stuck with 11.10.

    As I said farther up, touchpad is not recognized properly. This means no two-finger scrolling or multitouch. But it works as a clickpad well. I can rest my thumb on the bottom and mouse around and it works great. No right-side-scrolling like on older touchpads either.

    Wifi works great.

    Battery life I'm not sure yet. Rough estimate is that you'll get 5h on medium brightness not taxing the cpu constantly. So web browsing, typing, that sort of thing.

    Suspend works perfectly and quickly. Haven't hibernated yet.

    Also as I mentioned above, the brightness controls don't work until you run the command I posted. You have to run it every time it boots or comes back from sleep.

    Hmm, some bad news.

    Looks like the touchpad is a Cypress, which was previously used in the 15z. It's closed source and there's no linux driver and no reverse-engineered driver.

    At the very least I'm hoping to get scrolling down the side of the trackpad working.

    It does not seem to hibernate out of the box. The pm log shows it hibernating but then waking right back up. Doesn't crash it or anything. Just doesn't work.

    I don't really care though because it's supposed to be able to sleep for days.

    The next thing that's important to me is if displayport => vga adapter works. I'll let you know.

    It should hibernate did you dedicate a swap partition with enough space?

    Has anyone moved/mounted their temp folder into ram to reduce the number of read write cycles to save the ssd a bit? I remember reading an article about that but I don't remember where. Any thoughts???

    Yeah, I setup swap for hibernate. I really didn't look into it much. I don't use hibernate.

    Keyboard works perfectly. It's pure hardware.

    Right, I was just wondering if the backlight worked and turned on and off
