Description Lukas Ruzicka 2024-03-19 14:18:03 UTC 
I cannot boot into the Live session using basic graphics mode on neither EFI or BIOS. I have been trying this on a bare machine using the PiKVM device for distant connection. Unfortunately, I could not test directly.



Reproducible: Always

Steps to Reproduce:
Try booting the Fedora Workstation RC 1.9 iso.
Actual Results:  
When trying over EFI:
 - Grub appears
 - I select the Troubleshooting and boot in basic mode
 - After a while the machine restarts into BIOS mode. (see attached video)

When trying BIOS mode
 - Same as with EFI but nothing restarts and the machine remains on a black screen until reset.
 - When 'rhgb' and 'quiet' are removed, it remains on a screen with "Booting a command list".

Expected Results:  
Both ways should offer basic graphics mode.

I tested on this notebook:
Processors: 2 × Pentium® Dual-Core CPU T4500 @ 2.30GHz
Memory: 5.7 GiB of RAM
Graphics Processor: Mesa Mobile Intel® GM45 Express Chipset
Manufacturer: Hewlett-Packard
Product Name: HP G42 Notebook PC
sudo efibootmgr
EFI variables are not supported on this system.

And here basic graphics video mode booted successfully.

Tested F40 Workstation Beta 1.9 iso with basic graphics mode:

Asus B550 motherboard:
UEFI  boots OK
BIOS  boots OK

Thinkpad T480s:
UEFI  boots OK
BIOS  not tested (known to be broken for years)

Thinkpad P16v:
UEFI  boots OK
BIOS  not supported
Comment 7 Adam Williamson 2024-03-19 16:39:45 UTC 
On my bare metal test box (Asus H97M-E motherboard, Radeon 6500 XT graphics):

Workstation UEFI - OK
Workstation BIOS - OK

KDE UEFI - OK
KDE BIOS - OK

SS SHIPIT
Comment 8 Lukas Ruzicka 2024-03-19 17:41:13 UTC 
On the machine where it fails, the KDE iso works normally in basic graphics.
Comment 9 Kamil Páral 2024-03-20 09:25:20 UTC 
I tested today the very same machine that Lukas reported problems on, with the same image, and both BIOS and UEFI basic graphics mode boots just fine. So I assume this must have been some random accident with our particular machine. Since everybody else reported that it boots fine for them, I'll close this bug, and if we can consistently reproduce the problem on our particular hardware, we'll reopen it.
