Bug#976986: Dell Precision 3540: Unable to use gfxterm

[Paul Menzel]

Package: grub-efi
Version: 2.04-11
Severity: normal


Dear Debian folks,


On the Dell Precision 3540/0M14W7, BIOS 1.9.1 07/06/2020, I only see the 
GRUB console menu and the gfxterm one. `/etc/default/grub` is the default.

Entering the GRUB command line, I get the results below.

```

Does not switch to the gfx terminal.

Explicitly setting `GRUB_GFXMODE=1920x1080` (and `sudo update-grub`) 
also does not help.

Do you have an idea, how this can be fixed or debugged? Or should I 
report this upstream?


Kind regards,

Paul
