Re: My computer can't wake up after suspend

Show

$ grep -iE '.*(power|suspend).*' /var/log/Xorg.0.log
$ dmesg |grep -iE '.*(power|suspend).*' # less probable to be used.
# journalctl -b |grep -iE '.*(power|suspend).*

Are we going to guess, or will you be more cooperative ?

Re: My computer can't wake up after suspend

The last grep is unsuccessful because probably is in $HOME/$USER/.local/share/xorg/Xorg.0.log, as long as you've started X.
For such case try to switch to another TTY (CTRL+ALT+F[2-6]) and launch

top %CPU

Press Q to stop.
Then see what is taking the most CPU load. I doubt the computer could be responsive to allow the keyboard use.
Try also after resume

# journalctl --since=today |grep -iE '.*(power|acpi|suspend).*' > /to/file/hosting/pls/and/post/the/url

Re: My computer can't wake up after suspend

updated to kernel 3.17.4-1 problem remains
after downgrade to 3.17.2.-1 suspend works again unfortunatly can not get around virtualbox vboxdrv module which can not be activated any longer
virtualbox is more important to me then suspend so I life with 3.17.4.-1 for the moment.

Re: My computer can't wake up after suspend

to set a kernel parameter helped for me:
just added "dis_ucode_ldr"

sudo nano /etc/default/grub
GRUB_CMDLINE_LINUX_DEFAULT="resume=/dev/disk/by-uuid/d856dd64-8336-405b-84ef-b7b5ff7eb63c dis_ucode_ldr"

then:
sudo grub-mkconfig -o /boot/grub/grub.cfg

Re: My computer can't wake up after suspend

upgrading of kernel solved it...
