Ubuntu flashing caps lock key suspend 11.04

**joseph2153** · July 27th, 2011

My laptop:
HP dv51108ax
Amd Turion x64 x2
4gb ram
Ubuntu x86 11.04 with pae
Ati Raedon mobility 3450

The problem: I try to put my laptop into suspend, however the caps lock button will just keep flashing forever. eventually I just hold down the power button to turn it off, Does anyone know of a fix for this? I haven't had this problem in 10.04 or 10.10.

Flashing caps lock is a kernel crash, what ati driver you running?

in my case it was the new virtualbox 4.1 modules, disable them from starting up (with bum or rcconf) and try to suspend again.

Thank you! This was the problem for me too. I used bum as you suggested, and got a good suspend. So now I've fallen back from Virtualbox 4.1 to 4.0, and all is well. I'll try 4.1 again in a few months.

Many thanks!

I had the same problem with my toshiba. But I didn't want to go back to virtualbox 4.0. So I created this file as a solution :

Code:

root@tshb:/usr/lib/pm-utils/sleep.d# cat 54virtualhook 
#!/bin/sh
# Unload vboxdrv for a bug workaround on suspend on ubuntu 11.04

. "${PM_FUNCTIONS}"

suspend_vb()
{
    service vboxdrv stop
}

resume_vb()
{
    service vboxdrv start
}

case "$1" in
    hibernate|suspend)
        suspend_vb
        ;;
    thaw|resume)
        resume_vb
        ;;
    *) exit $NA
        ;;
esac

After a chmod +x on this file, when I suspend from the menu it works.

But ubuntu 11.04 has a weird bug, I just need to move my mouse to prompt the "locked screen" just before it suspends to get the resume right. If I don't move de mouse at suspend, resume is just a black screen.
