    Cannot go to sleep

    Hey all,

    So I've managed to get Xubuntu 11.10 running on my early 2011 15' MBP virtually flawlessly - pretty much everything is working as it should right now. There is one exception though (something that I'd be willing to overlook on my desktop, but not my laptop): sleep.

    If I close the lid, the computer doesn't appear to make any attempt to go to sleep, the white light on the front stays lit for the entire time. The computer is still fully awake and functioning normally after opening the lid, just with the screensaver running.

    If I manually put the computer to sleep through the menu, it just goes to the screensaver with the keyboard and trackpad usually becoming disabled (non-responsive) after that.

    I'd appreciate any help, as I'd love to use Xubuntu more but simply can't if sleep isn't working.

    Thanks in advance.

    Re: Cannot Sleep

    Just curious, are you running it as a standalone OS? Or as an application.

    Sleep is a very tough thing to get working and almost always related to non-free drivers for hardware. Check the 'Restricted Drivers' program and revert to OSS versions to see if that helps.

    I got a bit lazy, so it's a Wubi install.

    The only non-free driver I'm using is the proprietary ATI driver, as for some reason the open-source Radeon driver doesn't work properly for me. I'll give it another shot though.

    Check /var/log/syslog for any PM: exceptions.
    Code:
    grep 'PM:' /var/log/syslog
    Or dmesg. After attempting to suspend:
    Code:
    tail /var/log/dmesg  # check end of log
    less /var/log/dmesg  # browse all

    Re: Cannot Sleep

    Old thread which is not aimed at 11.10 but it might give a few pointers as to where the solution might lie (maybe)

    hope it is of some use

    Alright I took a look at the log, and the culprit is indeed the proprietary fglrx driver. I uninstalled it and re-installed the open-source radeon driver, but that still is broken (why I installed fglrx in the first place :/).

    Basically if I use the radeon driver, I get a totally black screen (the display doesn't even get power/signal) immediately after the boot screen. I'd appreciate any help getting this to work. BTW this MBP has a 6470M 'Seymore' videocard.

    You mean for the video error? I don't get anything, screen just goes dark after boot logo.
