Booting issue on Dell XPS 13 7390

agFM does not boot on Dell XPS 13 7390 (standard laptop not 2in1). My guess is its related to this: https://www.reddit.com/r/pop_os/comments/dzluza/dell_xps_13_7390_wont_boot_from_usb/

User says agFM works on other systems - just not on Dell XPS 13 7390.
Etcher/Rufus USB drives work OK for various Linux grub2 OS's - just not agFM UEFI64 on 7390.
agFM multi grub2 ISO and E2B agFM also does not boot on 7390.
Symptom is some 'small text' displayed which cannot be read + hang.

Interestingly Ventoy 1.0.14 boots just fine. In all fairness any text is gonna be small on a 4k screen thats 13in diag. Using Rufus 3.11 to write the agFM multiarch iso results in a hang with with no text output.

What will happen if you press [F4] then press [T] to switch to text mode?

Might help to know what the small text says? Can you take a photo/video and enlarge it, or connect a second monitor?

I got this laptop at the beginning of the year and use E2B on a daily basis. I've had this booting issue the whole time, but there's been several updates to both agFM and E2B over that time frame. I'm thinking at some point I was getting more text output. However now if I boot the agFM multiarch iso written with Rufus 3.11 I'm getting the Dell logo and no text output, just a hang. It doesn't respond to any key presses including the aforementioned f4,T or f4+T. The Dell logo never disappears, which is what further in dicates the hang for me. When I boot to the agFM on my E2B drive I get a period following by an underscore and a hang with Dell logo. The period and underscore stay onscreen too.

Someone reported that after this commit (de2bb17), terminal_output gfxterm leads to black screen.

That commit was on May 27, 2020. As previously stated the issue was present on my end from the time I first tried it on this machine back in January. Although I'm happy to test and troubleshoot anything. I haven't compiled this project before but I'll give it a shot.
