Suspend problem - suspend sometimes does a logout
 

Dell Studio XPS 8000 desktop

I am finding sometimes when I "suspend" the computer and then wake it back (by pressing the power button) I am presented with a login screen and any programs which were running at the time of suspend are terminated. I have captured some differences in the system log when suspend fails and when it succeeds. I need some help in interpreting.

The suspend/unsuspend process generates about 200 lines of log starting with and ending with The failed evolution (when I was logged out) contains the following lines which are not present in the successful evolution The successful evolution contains the additional line Other that the differences shown above the logs differ only by a few duration values (a few milliseconds here and there) and one PID Any kernel log interpreting gurus willing to take a look at this?

TIA,

The logs seem to be noting the fact that things closed. Do you logout inactive terminals? If you log in a bash console and do nothing at all with it, does it remain open?

How does it behave on hibernate?

Thanks business_kid,

If I simply open a bash terminal it stays there as long as I am logged on to the machine in gnome. If I suspend, and suspend works, the bash terminal is there when the computer wakes. If suspend does not work the bash terminal window is of course gone.

As to hibernate - that does NOT work AT ALL. When I attempt to wake the machine after hibernating I go through the normal boot process, am prompted to login and then find that networking is disabled(?) - no evidence that I did something other than a shutdown and reboot.

It needs to be compiles into the kernel by you.
CONFIG_PM_STD_PARTITION="/dev/sda9"

That's mine - sda9 is swap, btw. It loads a kernel, but doesn't run init, it reloads from swap instead. Suspend isn't reliable on this box, so I just use hibernate.

I think I will close this thread. It seems that the suspend problems are strongly related to having a virtual machine running when the host is suspended. I have trained myself to shut down any VMs before suspending and I am having a lot fewer problems.
