System freeze after suspend

Question

Since I installed Ubuntu 16.04 my laptop (HP Probook 450 G2) has issues waking up from suspend. Rarely it manages to properly wake up from suspend, but mostly the screen either stays black or it turns on, and completely freezes after 2 or 3 seconds, followed by a bit louder fan activity in both cases. I cannot switch to a tty shell, or do anything else apart from killing the power by holding the power button.

I tried following different solutions such as disabling USB Legacy, adding acpi_backlight=vendor acpi_osi='!Windows 2013' acpi_osi='!Windows 2012' to GRUB_CMDLINE_LINUX_DEFAULT, but nothing worked.

I switched to Linux Mint yesterday just to test if I have an issue there, but it still persists. Here is the output of /var/log/kern.log which shows the last messages from my previous session.

I have a 4.19 kernel and Nvidia driver version 390. I changed gdm to lightdm.

sudo apt install lightdm

Problem is solved now.

After using Ubuntu 16.04 LTS for a few days and everything was OK, I started to experience this freeze on suspend/sleep. I reinstalled the lightdm display manager and the problem didn't go away. I had similar logs to yours, but no hard errors.

What solved the problem for me was changing the default X.org video driver to the NVidia one.

This is located in Settings -> Software & Updates -> Additional Drivers

There I had the following option selected.

'Using X.org X server - Nouveau display driver...'

After changing it to:

Using NVidia binary driver ... (proprietary, tested)

Restart and everything is fine since then :)

I have had the same problem with Ubuntu 20.04 since installing some time ago - freezing on going into suspend - could only be dealt with by holding down the power-button for some six seconds or so. Tried all manner of suggestions - including those given above - but nothing worked, UNTIL I used the "Software & Updates" app to upgrade and, Hey Presto, all fixed!

Hope it works for you too.

Disable the "Ubuntu Dock" gnome shell extension:

gnome-extensions disable ubuntu-dock@ubuntu.com

Open /etc/systemd/logind.conf using editor like Vim, gedit:

sudo gedit /etc/systemd/logind.conf

You will see all these options:

#NAutoVTs=6
#ReserveVT=6
#KillUserProcesses=no
#KillOnlyUsers=
#KillExcludeUsers=root
#InhibitDelayMaxSec=5
#HandlePowerKey=poweroff
#HandleSuspendKey=suspend
#HandleHibernateKey=hibernate
#HandleLidSwitch=suspend
#HandleLidSwitchDocked=ignore
#PowerKeyIgnoreInhibited=no
#SuspendKeyIgnoreInhibited=no
#HibernateKeyIgnoreInhibited=no
#LidSwitchIgnoreInhibited=yes
#HoldoffTimeoutSec=30s
#IdleAction=ignore
#IdleActionSec=30min
#RuntimeDirectorySize=10%
#RemoveIPC=yes
#UserTasksMax=12288

Just change these entries value to suspend and all will work fine:

HandleSuspendKey=suspend
HandleLidSwitch=suspend
HandleLidSwitchDocked=suspend

If still not fixed :

HandleHibernateKey=suspend

Here is one method which helped me.

Edit grub configuration,

sudoedit /etc/default/grub

Change

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

to

GRUB_CMDLINE_LINUX_DEFAULT="text"

Then do

sudo update-grub

and reboot your computer.

Temporary Solution | Stuck On The Logon Screen | Even After Many Restarts

If you still find yourself stuck on the logon screen even after the hard restart then follow these steps to get out of this...

Restart your system : Press & hold the power button for 5-10 seconds
Start the system in recovery mode by selecting "Advance Option for Ubuntu"
Select the first options that ends with "(recovery)"
Choose "root drop to root shell prompt" option and hint ENTER Key (twice)
Execute the following commands:

sudo dpkg --configure -a

sudo prime-select intel

sudo reboot

Note: : This would work only if you're using a system that has two graphics cards (such as nvidia+intel or intel+amd) and the non-intel one is configured as the primary one.
