System hangs and will not go to sleep, and it cannot be awoken. Monitors are off but the system still seems like it's running as I can still hear the cpu fan spinning. Reproducible: Always Steps to Reproduce: 1. Put to sleep Actual Results: System hangs, monitors off but cpu fan running. Expected Results: System to shut down and sleep to ram.
Is anyone looking at this issue? I am still experiencing system hangs on sleep, more so now then before.
You could ask in a forum, if anyone else sees this issue.
I reinstalled kde on kubuntu 15.10, system still hangs going into sleep, I hear the fan spinning, power light on pc still on but monitor is dark and I cannot get the system to come back up. I am forced to always do a cold boot! $ kde-open -v Qt: 4.8.6 KDE Development Platform: 4.14.13 KIO Client: 2.0 Is there a shut down log I can view in the meantime to figure this out, maybe a hardware issue?
I see something like this sometimes. It may have something to do with processes running in a console (Konsole). With Plasma4 I could sleep the system with processes running in console windows with no problem. Now, I think it prompts me to kills them. I've believe I've have this happen in conjunction with multi-monitor issues such that I never see the prompt issues.
Hello this continues to happen, I am getting really frustrated this issues has not been getting any attention. I use to be able to keep my system running for weeks, only suspending to RAM. Now the system will hang going into sleep at time, only the monitors turn off.
Correction my monitors don't turn off, only the screen goes black but they remain on.
Having "Component: general, Version: unspecified" isn't a great way to get anyone's attention. I know you're not using Arch, but have a look at this thread where someone had similar symptoms. It might give you some ideas on how to diagnose the problem. https://bbs.archlinux.org/viewtopic.php?id=185731 This may not even be a KDE issue, you might have better luck starting in your distro's forums.
I am still having problems with the system hanging after upgrading it to kubuntu 16.04 LTS I did nothing one thing, when I disabled APIC on my BIOS I was able to suspend my system to RAM with no issues, however doing so would leave me with 1 out 4 core working on my CPU! As soon as I enable APIC on my BIOS the system started to hang again. Also I did update the BIOS on my system something ago with resolution to this nagging issue, but hopefully this new insight may help to getting this bug fixed! I would like to please have someone who on this, this is a long stand issue.
I had a typo, I meant to say ACPI BIOS settings.
This seems to be an issue with hardware and related to the kernel, i have a workaround from the kernel team: type this as root: echo 0 > /sys/power/pm_async Need to run command on a each reboot. The problem is caused by a parallel shut down of devices, the above command cases as sequential and orderly shut down of devices.
