Virtualbox & Okular misbehave after resuming from suspend

[garyyoung]

After I awaken my system from suspend, both virtualbox and okular misbehave.

In virtualbox after resuming, I can't boot into my guest VM (Windows 7) -- Windows hangs before getting to the login screen. If I try to load a saved machine state, the desktop appears but is frozen. A Kubuntu reboot fixes the problem in both cases.

After resuming, okular appears to be lacking in memory when reading pdf files. I can scroll down a single page, but at page breaks the program hesitates for several seconds. I thought at first that the files were simply too big to be read smoothly, but the same files present no problem when I do a fresh boot of Kubuntu.

I'm running 14.10, but this was a problem for me in 14.04 as well.

Here's a section of my suspend.log, in case that's helpful:

I may be missing the point, but I don't see the relevance of that thread. The thread's OP was having trouble getting suspend to work at all within KDE. I don't have that problem; it's only on resuming after a suspend that things go wrong. In any event, I did reinstall pm-utils, and it had no effect. Also, the OP in that thread suggested that he only encountered the problem on a system that had been upgraded. I've had my problem both on a clean install (14.04) and an upgrade (14.10).

Hibernate is off by default but can be enabled. "The Ubuntu developers disabled this a couple of years ago because hibernate didn’t work reliably on all systems – proceed at your own risk!"

Hibernate writes the contents of RAM to the swap partition if you have one. For hibernation your swap size would have to be bigger than your RAM size. If you don't have a swap partition or if it isn't big enough hibernation will fail.

Suspend has an icon on the "Leave" dialog.

Hibernate AND Suspend have mixed results, which appear to be highly hardware dependent. My acer suspends OK, but a relative noticed that when she came back from suspend the Network Manager and some software which was open didn't work properly afterwords. She had to do a power cycle to restore control.

In my power management dialog I have replaced all the time out actions with power downs, instead of suspend (which continues to use battery power to maintain RAM, mouse and keyboard) or hibernate which saves RAM to the SWAP partition and then powers down. (On power up the hibernate flag tells the OS to read the RAM state from swap.)

There might also be differences in the way devices expect to be initialized when coming out of suspend or hibernate. Remember, hardware manufacturers only test their stuff with Windows. Windows reinitializes peripheral devices upon resumption from either state. Certain Linux drivers might not do that -- thus, unpredictable behavior.
