Something wrong with boot screens (is just seems an aesthetic problem)

[massimiliano-polito]

I've just installed Ubuntu Studio 24.04 from a bootable USB stick. Everything is working well besides this "aesthetic" problem.

When I turn on the PC I run through 5 different boot screens but two of them contains an empty rectangular frame, see below.



Any idea about how to get rid of screens 2 and 4 above?

Thanks.

From grub menu remove the quiet splash to see it that helps.
I always remove it, but then see the entire boot process. It used to help as it was slow enough to see issues. But now with SSD and faster systems, it goes by very quickly.
It that helps, you can make it permanent by editing /etc/default/grub and updating grub.

Thanks for your reply and sorry for the bad images management.

I tried o remove "quiet splash" both temporarily (from the grub boot menu) and permanently (by modifying updating /etc/default/grub and running update-grub) but only the second occurrence of that blank box disappeared, the first one is still there.

Any idea about how to remove the first one also?

Did you change other settings like timeout in grub?
As it looks like it is the grub screen asking you to choose, but then blank.

Post this in code tags:
cat /etc/default/grub

No, I only removed "quiet splash", see below.

# Uncomment to disable generation of recovery mode menu entries 
#GRUB_DISABLE_RECOVERY="true" 

# Uncomment to get a beep at grub start 
#GRUB_INIT_TUNE="480 440 1"

This is the file that came with the installation, I didn't make any change besides the one reported above.

You changed grub timeout to 0.
That is not normally suggested as then you cannot get to grub menu. I change default of 10 to 3 so menu only appears for 3 sec.

I also like to see menu so change hidden to menu.

[massimiliano-polito]

I didn't change the timeout to 0, as I said I only modified GRUB_CMDLINE_LINUX_DEFAULT setting it to "" (removing "quiet" and "splash"), al the rest comes from Ubuntu installation.

Anyway, I've also tried modifying GRUB_TIMEOUT to 10 but the frame is still there. I also set GRUB_TIMEOUT_STYLE to "menu" to see if anything changed but the empty frame is always there (and I couldn't see any new menu appearing).

Apparently, neither GRUB_CMDLINE_LINUX_DEFAULT nor GRUB_TIMEOUT nor GRUB_TIMEOUT_STYLE are of any help to make it disappear.

Just to give you a piece of information more, I've tried this:

I selected "Advanced options for Ubuntu" in the first screen so I was presented another menu where I had a couple of choices among which kernel to load.

I just hit "enter" (so the first choice was selected) and the boot process continued.

Following this sequence no empty frame appears.

The recovery mode uses nomodeset.
Instead of quiet spash try nomodeset on standard Ubuntu entry to see if it is the same as recovery mode.

Nomodeset is normally a temporarily setting because of video issues or proprietary video driver is not installed.

[massimiliano-polito]

I modified again grub.cfg, this time I used:

GRUB_CMDLINE_LINUX_DEFAULT="nomodeset"

but the first blank frame is still there.

I'm thinking that I have to renounce to having a perfect Linux box and live with this empty frame
