Mageia forum

Hi everybody,

I'm going to use Mageia 5.
My main problem is that it doesn't hibernate (if i press hibernate key from application launcher, it does nothing except requiring to enter my PassWord again- like when i lock my PC.)

sleep either doesn't do anything, or when it goes to sleep, immediately wakes up and show a black screen.
I think the problem is because of my VGA Driver, cuz, for example, if i go to tty2 by pressing Ctrl+Alt+F2, when I come back to tty1 by pressing Ctrl+Alt+F1, i again only see a black screen.

My desktop spec:
Mageia 5,
Cpu: intel dual core,
vga: nVidia 450 gtx,
HDD: SSD 120GB,
Ram: 8GB

Thanks

Hi, what desktop environment and what Mageia installation medium did you use?

Hi doctor,
i'm using KDE and by Mageia installation, if i got it right, i used USB and UEFI. (did you mean that?, sorry if i got it wrong).

Thanks

No, I meant which of the download options did you choose from https://www.mageia.org/downloads/ ?
One of the live CD/DVDs or the free DVD ... ?

Anyways, please show the output of the following commands, run as normal user:

Code: Select all

ps -ef|grep -v grep|grep polkit
cat /run/systemd/users/$(id -u)
pkcheck --action-id org.freedesktop.login1.suspend --process $$
systemd-inhibit --list
pkexec whoami

For the last command, you should be asked for your root password in a popup - please enter it.

And as root, please try the following and describe the results here, or past the output you get here

Code: Select all

systemctl suspend
systemctl hibernate


Please also try as normal user the following:

Code: Select all

qdbus org.kde.Solid.PowerManagement /org/freedesktop/PowerManagement Suspend

Hi Doktor,
Thanks for the reply

"systemctl suspend" put pc on sleep and immediately it turned on
"systemctl hibernate" put pc on hibernate, but i turned my pc on, it took a lot to got booted and again i didn't have any screen and had to do hard reset.

thanks

is there any way to change Nvidia driver with nouveau?
i think nouveau is an opensource one,
maybe that fix the problem.

Sure, run drakx11 and select Xorg => nouveau under "Graphics card" : http://doc.mageia.org/mcc/5/en/content/XFdrake.html

Thanks doktor for your reply,
Actually i did that and moved to nouveau, but it made things worse, thus I revert it to Nvidia again,
but this time i set my resolution (it was automatic) and maybe made some small changes (which i don't remember exactly). and finally it got solved and now magically both Hibernation and Sleep work.
However, I don't know how and why

I'd like to thank you again,
and ask you whether we should title this thread as "SOLVED" or not?
and what would be the solution? is it changing the resolutions?

Thanks

Yes, and I have no clue what fixed it on your box.

Thanks Doktor,

Can i ask you why some programs like FireFox prevent Mageia goes to sleep or Hibernation? and how can i change that?
for example, i have to close firefox to go to hibernation or sleep, otherwise, either it won't go sleeping or hibernating, or my system gets turned on immediately after going to such states.

Thanks

You can ask but I have no idea. Firefox doesn't prevent suspending here, and I've not heard of such an issue before.
Maybe some video or sound is playing so the session is still considered active but that shouldn't be a problem.

Yes, that's strange,
i dunno why, but when the firefox is open, it won't into hibernation or sleep.
