Ubuntu – Toshiba Satellite U400 does not resume from suspend

suspendtoshiba-satellite

I have upgraded from ubuntu 10.4 to 10.10 and the issue seems to be that when I close my lid I have set the computer to suspend. When I open my lid I get a black screen with the login but keyboard is not working. I am using a Toshiba Satellite U400, and didn't manage to find something suspicious at my log files. Any ideas?

  • I have a Toshiba U-400, and Maco's answer here is similar to Pitto's.

    In our case, it's the bluetooth module that prevents the laptop from resuming from suspend. You need to add this line to /etc/default/acpi-support.

    MODULES="toshiba_bluetooth bluetooth btusb"
    

    That should get you running again. Despite this change, perhaps 1 in every 25 or so suspends (not resumes) will fail for me. When it fails, it cycles the CPU and fanspeed up pretty high. Do not trust this laptop to suspend correctly. It suspends very quickly, so when you close the lid, keep your eye on it for the 3 or 4 seconds it takes to complete (the amber light under the trackpad should go off).

    If it doesn't, you're looking at a fire hazard!
