So it’s installed but not running.
sudo systemctl start haveged to start it during the current session
sudo systemctl enable haveged --now to start it automatically at boot

Btw, that service starts if ConditionKernelVersion=<5.6
If kernel 5.4 booted normally then you might need haveged after all. Just edit
/usr/lib/systemd/system/haveged.service so ConditionKernelVersion=>5.6

23

The suggestion was to use a LTS-kernel (not the newest one) :wink:
:footprints:

24

Looks like there is no driver installed… :thinking:

25

The is the behaviors I talked about. Kindly check out the video

What could be the fix

26

It doesnt boot pass this phase and sometime it does.

27

Personally, I never open foreign videos to understand OP’s issues…

28

Did you enable haveged?

29

Yes, i did

30

systemctl status haveged

31

I mean no harm. I just need to show the behavior thats why i recorded the video. I can place my hand on the fix

32

This video is absolutely not helpful. We need to see what’s going on under the hood, not look at the black screen. The working hypothesis right now is that the problem is a lack of entropy.
Provide output of systemctl status haveged once again

You didn’t enable haveged. You need to:

  1. Edit /usr/lib/systemd/system/haveged.service in a text editor and replace string ConditionKernelVersion=<5.6 with ConditionKernelVersion=>5.6
  2. sudo systemctl enable haveged --now
  3. Check systemctl status haveged. Make sure it’s Active: active
  4. Reboot and see if it helps

This is the output after doing the above steps:

It’s running now. Time to reboot

38

Please do you know the Kernel version that works well with Dell XPS 15, all kernel version works but the boot process is slow and sometimes it shows a black screen while booting. Kernel version 5.4.0 works perfectly well but wifi and Bluetooth do not work. what can I do, please?

39

Why not try the latest LTS kernel, linux61 like was suggested earlier?
Might have added support for drivers that is not available in linux54
