The "signal input is out of range" issue is easily resolved. The problem is twofold. This occurs during installation and upgrade.
So from Ubuntu 12.04, 14.04, 16.04, 18.04, 20.04, and 22.04, the resolution setting was moved from the start-up manager to the kernel. Before, it was solved using Startup-Manager, but since “Startup-Manager is dead,” it was dropped from Ubuntu 12.04’s repository.
Start your boot device during installation, press F6 only select ACPI and nomodeset and continue with installation in safe graphics.
In Simple steps
sudo nano/etc/default/grub
find the line;
#GRUB_GFXMODE=640x480
Remove the # and change 640x480 to the preferred mode you have with your monitor. e.g 1024x768, 1280x1024, and 1600x900.
Then find grub command line setting;
Add nomodeset to the GRUB_CMDLINE_LINUX_DEFAULT value as shown below.
GRUB_CMDLINE_LINUX_DEFAULT="nomodeset"
Save, then type
sudo update-grub
You need also to update your OS after updating grub
sudo apt update
You can also follow all steps here because it save me after months searching online for my old desktop PC.
/boot/grub/grub.cfg
of your server install and search for theset gfxmode=
line. The current value is probablyauto
. You can specify grub's display resolution there, e.g.set gfxmode=640x480
. Try setting it to a value that both your monitor and graphics adapter support and tell us if you can enter grub. Of course, note down the current value so you can revert it if it didn't help.
