LinuxCertified LC2210D Laptop Review

Posted by timothy on from the that's-where-the-linux-laptops-are dept.

Provataki writes "OSNews posted a review of the LinuxCertified LC2210D laptop, running the latest Ubuntu. The laptop delivers pretty well and it has modern characteristics for a fair price but it's not without its small configuration issues. It is also another proof that Linux's ACPI sleep support does not work on most laptops out there, even the ones picked for best compatibility with Linux."

    ACPI sleep works on most modern laptops. http://www.ubuntulinux.org/wiki/HoaryPMResults has rather more "Yes" entries than "No" ones, and a large number of the failures are now well understood. Toshiba, IBM and (surprisingly) Sony seem to be good for ACPI support. For HP, it depends on the range - a lot of their hardware is very different. Older Dells seem good, and some of their modern stuff works without problems.

      Additionally, the vast majority of sleep problems aren't in the kernel, they're in the bios (specifically, the DSDT as compiled by Microsoft tools). Go to acpi.sf.net for more information on broken DSDTs for more information on what this DSDT brokenness means to hardware compatibility, both device (e.g. sound cards) and suspend-resume and how to fix it (and maybe you're lucky and someone's already fixed your DSDT!)

      Without fixing the DSDT, your best bet for suspend-resume on Linux is to use software suspend 2, as it seems to sidestep the BIOS/DSDT brokenness pretty well.

      This isn't true for the majority of semi-decent hardware. Most resume failures are entirely down to Linux not resuming the IDE controller properly, with most of the remainder being video and i8042 related.

    how can you say that sleep is only an issue with 0.01% of laptop users? The reason that I got a laptop was so that I could be mobily productive and a big part of that is being able to go a long time between charges. I imagine most people have laptops for the same reason and so it is an issue.

    I couldn't agree more. I have a Gateway 7405GX that is completely supported EXCEPT for sleep (well, also the Broadcom wireless [ndiswrapper works, tho, even in 64-bit mode] and maybe the various memory card readers, which I never tested since I don't use any).

    In all my fiddling with various Ubuntu and SUSE 9.3 installs I've only seen this laptop wake up and actually work properly once, and that was apparently just a fortunate accident since I couldn't reproduce it.

    I'd LOVE to use Linux on this machine, but having to shutdown every time I want to move the thing more than a few feet is just too tedious. It destroys the whole point of having a mobile computer.

    In XP I can just close the lid, drive wherever, open the lid and keep going where I left off. XP's hibernate is fantastic in that regard, too, since you can hibernate and come backs DAYS later and pick up exactly where you left off without having to worry about the gradual dying of the battery while the machine sleeps.

    The day I can get even close to that kind of convenience while running Linux is the day I blow the XP install away for good. I'm not going to hold my breath, though, since I've been waiting for YEARS for proper Linux laptop support and the pace of improvement seems glacial.
