I am trying to install Ubuntu Server 20.04.4 LTS (No X Server, no GUI) on my Intel NUC. My HDMI output is redirected to a video capture card (if that matters) which supports 4k display which feeds video into my laptop. The problem is that when I start the installer it looks like this: https://i.stack.imgur.com/lRsXk.png Basically it's just too small for my eyes. I need to install Ubuntu Server with HWE kernel as this is supporting my wifi card and by pressing 'e' and I'm presenting with this screen: https://i.stack.imgur.com/4r4Cr.png I tried here changing: set gfxpayload=1024x768x32 and the pressing F10 to boot but it didn't had any effect. What can I do to lower the screen resolution? videoinfo output Adapter 'EFI GOP driver': * 0x000 3840 x 2160 x 32 (15360) Direct color, mask: 8/8/8/8 pos: 16/8/0/24 0x001 640 x 480 x 32 (2560) Direct color, mask: 8/8/8/8 pos: 16/8/0/24 0x002 800 x 600 × 32 (3200) Direct color, mask: 8/8/8/8 pos: 16/8/0/24 0x003 1024 x 768 x 32 (4096) Direct color, mask: 8/8/8/8 pos: 16/8/0/24 0×004 1280 × 1024 x 32 (5120) Direct color, mask: 8/8/8/8 pos: 16/8/0/24 0x005 1600 x 1200 x 32 (6400) Direct color, mask: 8/8/8/8 pos: 16/8/0/24 0x006 1920 x 1440 x 32 (7680) Direct color, mask: 8/8/8/8 pos: 16/8/0/24 EDID version: 1.3 Preferred mode: 3840x2160

Did you try without the "x32" on the end?
It doesn’t make any difference
With Ubuntu installed I can see in the dmesg -T output that it's switching to efifb I don't know how to see the log file for the installer. Anyway, if anyone can solve this mystery, please help! How can I control the resolution for both the Ubuntu Server installer and the OS itself after being installed? Here is the dmesg output: https://paste.ubuntu.com/p/ypmmwz2PKn/ What's interesting is this: [Sat Apr 16 13:20:21 2022] efifb: probing for efifb [Sat Apr 16 13:20:21 2022] efifb: framebuffer at 0x4000000000, using 32400k, total 32400k [Sat Apr 16 13:20:21 2022] efifb: mode is 3840x2160x32, linelength=15360, pages=1 [Sat Apr 16 13:20:21 2022] efifb: scrolling: redraw [Sat Apr 16 13:20:21 2022] efifb: Truecolor: size=8:8:8:8, shift=24:16:8:0 [Sat Apr 16 13:20:21 2022] Console: switching to colour frame buffer device 240x67 [Sat Apr 16 13:20:21 2022] fb0: EFI VGA frame buffer device [Sat Apr 16 13:20:21 2022] Monitor-Mwait will be used to enter C-1 state [Sat Apr 16 13:20:21 2022] Monitor-Mwait will be used to enter C-2 state [Sat Apr 16 13:20:21 2022] Monitor-Mwait will be used to enter C-3 state Maybe someone knows how to control the resolution of the efifb in both the Ubuntu Server installer and the OS after being installed
The solution was found, apparently, in some Raspberry Pi forums. After all the Intel NUC is just a more powerful RPi. I have added: video=HDMI-A-1:1920x1080M@60 as a parameter to the kernel as seen in the picture: https://imgur.com/a/YvI1pNl and the screen resolution is now much better: https://imgur.com/a/Q5VIuGp Now, I don't know what exactly: video=HDMI-A-1:1920x1080M@60 means. Why HDMI-A-1 and what is M in 1080M. But it works.
