Fedora 21 Workstation desktop machine has problem waking up
I recently upgraded form Fedora 17 to Fedora 21 Workstation on a desktop machine. There are many changes and I'm still trying to figure out how to get everything set up. Fedora 17 was about as stable and well functioning as I have seen a Fedora release and it was close enough to the Unix systems I had spent most of working life administrating. This is the same hardware no changes other that software.
Now on my Fedora 21 I'm having random occurrences of the screen just breaking into gibberish and the entire system freezing. I have to hard reboot from power switch to regain control. Alt-Ctrl-Del no effect neither can I Ctrl-Alt-f3 to get into a console terminal. The other problem (maybe related, maybe not) is that after the system goes to sleep it sometimes (not always) will not wake up. Again only solution is a hard reset.
I have search Fedora Forum and can't find any reports like this and also have googled but again no success. Hopefully I just have something not setup or setup incorrectly. I see in gnome-tweak-tool a power setting but it only seem to be related to laptops.
Any help appreciated.
I think my desktop machine is trying to behave like a laptop and go into hibernation. This morning the machine did not have a power indication and when I powered up after about 10 minutes it came on although no sign of a power on boot (ie. no firmware splash screen or fedora balloon filling just came on with the login lockscreen). How can I stop this from occurring, I have cron jobs that need to run in the night.
What was the way you updated the system from 17 to 21? There were many fundamental changes especialy related to systemd and wayland. I would suggest you avoid gnome in the first place to test.
I did a new install and just mounted my own /home partition. With Fedora 17 I had my screen lock after a time on inactivity but the machine kept running and my cron jobs ran, now the machine seems to power down and nothing happens. I may have thought the machine was hanging but it was in the process of hibernating or sleeping. Last night is the first time it just appeared to have no power when I checked this morning but pressing the power button seemed to bring it to life but it took a long time. Can you turn all the sleep and hibernate off in fedora 21? I just want the screen to lock after a period on inactivity.
Use gnome-tweak-tool to set power actions - if there will be any.
I set the power setting to "nothing" in gnome-tweak-tool. Probably be tomorrow morning before I really will know how it's going to behave, will update again then. Tks
