    Re: [HowTo]: Fix suspend and hibernate on laptops

    Hey James,

    Thanks for you answer.

    However, I kept looking for answers and found this today in omgubuntu:

    It worked for me in 11.04 perfectly. I just followed the instructions there.

    Re: [HowTo]: Fix suspend and hibernate on laptops

    I enthusiastically installed Ubuntu for the first time on a Toshiba M100 last night and set it to hibernate when I had finished with it for the evening. After being met by an unresponsive system today and doing a quick search online I learnt that there seems to be an issue with hibernate. As I had nothing of any value on the system I did a re install. I had to use an additional monitor in order to proceed as the Toshiba display would not wake up. Now that the re install is complete the only way that I can use the laptop is by using the extra monitor.

    Re: [HowTo]: Fix suspend and hibernate on laptops

    Update for 11/10 Oneiric:

    Pressing the power button again failed to suspend my laptop. I have to something different with nearly every release.

    I tried making panel launcher with
    gksudo "pm-suspend --quirk-s3-bios --quirk-s3-mode --quirk-dpms-on --quirk-vbe-post --quirk-vbestate-restore"
    and that worked but I hated having to enter a password just to suspend.

    The real solution is simpler:
    In /etc/acpi/powerbtn.sh
    comment out the last line:
    #/sbin/shutdown -h now "Power button pressed"
    and enter the suspend command, along with whatever quirks your machine requires:
    /usr/sbin/pm-suspend --quirk-s3-bios --quirk-s3-mode --quirk-dpms-on --quirk-vbe-post --quirk-vbestate-restore

    Finding the quirks is a matter of trial and error.

    I think grub no longer needs modification, but my one line
    GRUB_CMDLINE_LINUX_DEFAULT="i915.modeset=1"
    doesn't seem to hurt anything.
