Hi,

Recently I've been having a problem with waking up my desktop (KDE) after it idles for a while and seems to go into a power save mode. Neither mouse nor keyboard can wake up the system and when I toggle the monitor power switch I get a message that the monitor is entering the power save mode. It does not happen every time the system goes idle, but often enough to be really annoying now. The only 'fix' I've been using is to reboot, but that's obviously not a good way. Not sure where to start troubleshooting this, any ideas? Is there a way at least to drop down to console and wake up the system from there?

Regards,
Alex

P.S. I have not played with any power save features yet, such as suspend to RAM or disk, although I would like to, just haven't had the time.

P.P.S.

Not a fix, maybe a work around and to determine what is happening:
When it happens, can you do ctrl+f1 and get the main console? If so, does switching back to X with ctrl+f7 then wake it up?

For switching among Linux virtual terminals, you meant alt+fN, not ctrl+fN. For switching from X11 to a Linux virtual terminal, you meant ctrl+alt+fN, not bare ctrl+fN.

OP: please explain in more detail about exactly what state the system is in. Typically people who refer to powersaving mode are talking about S3 (suspend-to-ram) or S5 (suspend-to-disk), but you say you are not using those. When the machine is in this state, does it respond to network activity?

SirRobin2318, Hu - thank you.

ctrl+alt+fN does switch to the virtual terminal, I can loop through the terminals with alt+fN and switch back to X with ctrl+alt+f7 (alt+f7 works too). When switching back to X I either get the desktop back right away or a black screen. And if it's black a few more switches to the terminal and back or powering the monitor off & on seems to work.

As far as the state machine is in when it is non-responsive, I am not sure. I do not activate anything, like Sleep or Hibernate options in KDE logout menu, I simply leave it and when I come back it may be ok, or may be non-responsive. I do have Screen Locker activated in KDE settings (Display & Monitor -> Screen Locker -> Simple locker); perhaps I should try using a screensaver.

What kind of network activity do you mean, should I try to ping it, ssh or something else? I'll give it a try.

Thank you for your help, it seems we have a workaround for now. I would like to properly set up the suspend-to-ram and suspend-to-disk modes however, is there a good guide on how to go about it?

Regards,
Alex

If you can recover it via vt switching, then the network test is not needed. The machine is mostly functional. Please try disabling the screen locker entirely and using XScreenSaver instead.
