[RESOLVED] Black screen after first start

[Dido1]

Hi I see some similar problem in the forum but no one really match with mine.
I had Kobuntu 22.04 running in my desktop. Now I installed 24.04 in dual boot with Win 11. After installation and reboot my grub appear and I can login in Kubuntu without any problem. Restart, grub again no problem but after blank screen.
I try to install again 3 times and always the same, first start perfect and after blank screen. Between the restarts I never start Win11. After that I try to install Ubunto 24.04 and works perfect, so I think is a problem of KDE graphics.
I ave AMD graphic card so should not be driver issue. Any idea? Tks

Surfing I found that should be a bug on loading quiet splash. https://bugs.launchpad.net/ubuntu/+bug/2063877
For me it worked in this way:
Reboot pressing SHIFT if your Grub not show
Launch Kubuntu in recovery mode

Edit /etc/default/grub
Change line: GRUB_CMDLINE_LINUX_DEFAULT='quiet splash'
in
GRUB_CMDLINE_LINUX_DEFAULT=' ' (remove quiet splash), save end from terminal

sudo update-grub

[Dido1]

Now working fine

Thanks for sharing - so this could help someone else, too.

Perhaps it was a problem with Plymouth…
You deactivated Plymouth by removing splash from GRUB_CMDLINE_LINUX_DEFAULT in /etc/default/grub.

Now I removed only SPLASH and is also working but at least with a clean screen

GRUB_CMDLINE_LINUX_DEFAULT='quiet'

Thank you for this fix.
Yesterday I upgraded from 22.04 LTS to 24.04 LTS: everything went smoothly and I used my laptop all day, no problems.

This morning, boot, grub and black screen.
Removing "splash" from the GRUB_CMDLINE_LINUX_DEFAULT fixed the boot problem.

I have an AMD integrated graphics card, Ryzen7 CPU.

This is a very strange behaviour... After the update, everything worked for a day (even reboots), then the next day my laptop is "bricked".
I'm glad for this post, really :-)

I’m new to Linux but having the same issue, I believe. How do I edit /etc/default/grub from the recovery mode root shell prompt? Do I need to reinstall and edit it from the fresh installing before restarting?

[Schwarzer Kater]

Welcome.

If you can get to the recovery mode root shell of your installation, enter:

• cp /etc/default/grub /etc/default/grub.orig (this makes a backup of your /etc/default/grub file first)
• nano /etc/default/grub (to open and edit the file in the nano CLI text editor - edit to your liking and press [Ctrl] [o] and [Return] to save and afterwards [Ctrl] [x] to exit
• update-grub (to update the boot loader with the new settings)
• reboot

Good luck.

If this worked for you and Kubuntu boots afterwards, you can also have a look at Essential and strongly recommended things to do directly after a Kubuntu 24.04 LTS installation.

Thanks a ton, Schwarzer and Dido! This worked perfectly and I went ahead and did everything on your essential and recommended list. I really appreciate the help!

I just wanted to chime in and say, "me too" about this issue, and the advice above worked for me.

[Schwarzer Kater]

[…]

sudo update-grub

For the sake of completeness:

To get to the GRUB boot menu press [Shift] for a ("legacy") BIOS system or press [Esc] for an UEFI system.

And don't use sudo in case you are already in a root shell (there is a "#" at the input then instead of the "$").

Hi, Linux newbie here and first-time poster to these forums o/

Has this been fixed yet?? I've been recommending Kubuntu to a lot of people, but this bug will definitely negatively affect their thoughts about Linux as a whole if they try it out.

thanks for the help, removing quiet splash helped me too.
Dell Inspiron 15 3530 6.8.0-35-generic, Kubuntu 24.04

Same Issue, the restart after "upgrading" to 24.04 from 23.10 was fine.
Shut computer off and went to boot in today to just a black screen after BIOS screen.
Thank goodness for Timeshift and always have a live linux usb around. I guess I'll just wait.
