[Carbon RC2] Initial installer screen not displayed on ThinkPad X220

Booting a BunsenLabs Install media usually gives a grub menu with various Live and install options.  On my ThinkPad X220, the Carbon RC2 grub menu is missing, and the screen is blank.  Pressing Enter opens a live session; pressing down arrow 3 times, then enter starts the installer.  The install seemed successful.  This was a UEFI boot.

A Boron Install media made December 2024 does not have this problem on the X220.  (also a UEFI boot)

The Carbon RC2 install media displays the grub menu as expected on a Dell Optiplex 7040 SFF desktop system.

I can provide additional configuration information, but right now I would be guessing about what might be useful.

BunsenLabs is great!

Could you try one of the earlier Carbon media here, rc1 or alpha4:

Do you get the same issue?
How about with a regular Debian Trixie iso?

How about with a regular Debian Trixie iso?

I'd recommend comparing it to the LIVE Xfce build...

Re: [Carbon RC2] Initial installer screen not displayed on ThinkPad X220

This evening I tried a Debian Trixie iso burned to a USB thumb drive.  A grub menu appeared with these options:

Graphical Install
Install
Advanced Options ...
... and two more

If things go well, I will try the Xfce live build between snow shoveling sessions this weekend.

^ If that worked, the Carbon RC2 ISO should work. Download it again, check the sha256sum (download that too) and cp it. Example...

~ 
❯ cd Downloads

~/Downloads 
❯ ls
carbon-rc2-260111-amd64.hybrid.iso  carbon-rc2-260111-amd64.hybrid.iso.sha256

~/Downloads 
❯ sha256sum carbon-rc2-260111-amd64.hybrid.iso
d0beb580ba500e2b562e1f39aa6ec02d03597d8f95d73fd86c1755e3fee1ef7d  carbon-rc2-260111-amd64.hybrid.iso

~/Downloads took 2s 
❯ sudo cp carbon-rc2-260111-amd64.hybrid.iso /dev/sdb;sync

Adjust your USB drive path as needed. Make sure that drive is empty. Open the sha256 file in a text editor and match the hash with the terminal output to check validity.

The Xfce live build behaves the same way as the Carbon RC2 media.  Blank screen after selecting boot media; an Enter keypress makes the Xfce live system load.

I had not seen the previous post; I will look into it.

sha256sum says that my original download of carbon-rc2-260111-amd64.hybrid.iso is correct.

# dd if=carbon-rc2-260111-amd64.hybrid.iso of=/dev/sdd bs=16M status=progress oflag=sync

The thumb drive made in this way behaved the same way as described in the first entry in this thread.

Re: [Carbon RC2] Initial installer screen not displayed on ThinkPad X220

The Xfce live build behaves the same way as the Carbon RC2 media.

So this tells us that the issue is either with the Debian Installer itself, or with live-build which I think is used in making the Debian live isos as well as BunsenLabs.

Can you confirm whether the same issue occurs with the earlier BL Carbon rc1 or alpha4 isos on Sourceforge?

RC1 behaves the same way as RC2.  Grub menu presents as expected on Dell Optiplex 7040, Grub menu is invisible but working on ThinkPad X220.

Re: [Carbon RC2] Initial installer screen not displayed on ThinkPad X220

^Thanks for checking that out. Since the xfce live iso behaves the same, it looks like a live-build issue that might be difficult for us to fix. If you have the time to check whether the grub menu displays with a regular Debian Trixie iso (ie not live) that would confirm the issue is with live-build. No need to actually do the install of course - just see if the grub menu is invisible on your ThinkPad X220.

^Fortunately, I already tried that.  See #4 above.  Regular Trixie works as expected.  I guess I need to figure out how to file a Debian bug report on live-build.
