Probably not. Early boot graphics is controlled by the BIOS. So if the BIOS has chosen not to light up a monitor by then, we can't use it till the OS and full graphics driver stack loads later. Usually the BIOS will only display on one monitor, whichever it deems to be primary.
GRUB probably has no notion of "monitors". At that stage there is only a graphics framebuffer (EFI/VBE/VGA) provided by the BIOS. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/2110949 Title: No output to USB-C monitor after logging in with the laptop closed Status in linux package in Ubuntu: Incomplete Status in mutter package in Ubuntu: Incomplete Bug description: 1) Description: Ubuntu 24.04.2 LTS Release: 24.04 2) not sure which package this applies to 3) I have two monitors connected to a laptop in clamshell mode. When I log out of my profile, I see my background wallpaper blurred, and my username on the primary monitor that I have setup, as expected. 4) However, when rebooting this layout is ditched for some reason: - I see a gray background (not the main problem) - the username/login page is on the secondary monitor - it is the wrong orientation ( the secondary monitor is setup to be portrait mode) but the login appears horizontally, seeming quite unpolished - the scale is completely wrong. Then upon logging in, there is no display output at all, the monitors detect no USB-C input. The workaround (which is quite cumbersome) is to disconnect the USB-C cable from the laptop, remove the laptop from the dock, and open up it up, log in, connect the usb-c cable so that it recognises the configuration, and then close the laptop and put it back into the dock. The monitor configuration is: Laptop -> USB-C -> Dell P2224HE (primary, landscape) -> Display Port Daisy Chain -> Dell P2224HE (secondary, portrait). When booting the same configuration in Windows, it seems to remember the layout somehow so that the username/login screen is shown on the primary monitor in the correct orientation with some splash screen.
