When i boot up the laptop i get a black screen for 15 seconds just after the feather screen untill my desktop is visible. This is something new, used to be much much less then that. Ayone any idea what might be the problem?

Press the Home key when you reboot for verbose messages, see where it is sticking.

What is the output of:

Code: [Select]
systemd-analyze blame
and check the last reboot messages from /var/log/syslog.

Hi Jerry,


When i check syslog it doesnt shows anything from Aug 18 13:44:09 to Aug 31 09:43:54 after that no entries.


When i press the Home key during reboot the only thing i can read before its gone is scanning for btrfs

If you don't use the BTFRS file system, you're probably using etx4, you can remove it:

Code: [Select]
sudo apt purge btrfs-tools
Set a Restore Point first.

The 15 sec black screen is still here after the feather screen. No btrfs scan anymore. Not sure why it takes so long.

Look through Menu, System, System Log for any hints of the delay.

Hi,

Your sda (harddrive) takes a few seconds there.
Could it be a problem with the harddrive itself hitting a bad sector / calibration problem?
(weird clicking hard drive sounds is an almost 100% indication)
You could check the files sytem with fchk, and the hdd with smartmontools / smartctl
Better be safe than sorry ;)

Another idead, albeit usually from Windows experience ;) ... Could be an antivirus scan running, if you have one isntalled.

Cheers!

There are no clicking sounds, its an SSD
I have to look into smartctl, never used it before.

With an SSD you can almost forget my post. Lucky you! ;)
Maybe try to boot Linux Lite from USB just to confirm its your install.
Otherwise, maybe checking if theres a driver update.

Just throwing ideas... good luck! :-S

if you like seeing the text go by as it boots, rather than a splash screen, then a blank screen

edit /etc/default/grub, remove the "quiet splash" and just make it "" and reboot..and wowza...scrolling words :D

Of course do a
Code: [Select]
update-grub as well
