[esos]

HP-laptop:
Using grub.cfg like this, it will show the menulist on both(lcd-screen and hdmi-monitor).

Now about Dell xps12 touch-screen which the display screen is already tossed due to leaking and sticky fluid/glue(maybe mercury).
Grub2 menulist wont show up on hdmi monitor.
How to change/modify Grub2 menulist configuration to be able to show on my hdmi monitor? Anybody?

[williwaw]

can you see anything on a different monitor?
what exactly do you see on any monitor?
what exactly do you see on the hdmi monitor?
can you boot anything else on the dell with any monitor? if so, post your grub.cfg on the dell.
I assume you are trying to boot each machine with the same USB?

[esos]

Only using the hdmi monitor for hp-laptop, that's what I have.
The configuration grub.cfg is the same like on the hp. Both are multiboot setup which hp using HDrive and dell SSD. I dont use USB.
Dell menulist doesnt show up on the connected hdmi monitor, so I can not choose any OS, just boot up straight to the default OS.
Is there any missconfig dell grub.cfg?

[williwaw]

just boot up straight to the default OS.

so it does boot? maybe after grub times out? but you want to be able to see grub to select something different?

if so, post your dell grub.cfg for comparision. the uuids should be different. maybe something else too.

looks like MX? do you have a puppy installed?

[esos]

grub.cfg from puppy is to simple, which not working in hp-laptop for hdmi monitor, see my first post.
multiboot: slacko, upup, fossapup, bookworm, ezos. All tested and bootable, that's why I need menulist.
