Laptop monitor not turning on when external monitors are connected at boot

Hey all,

I installed Fedora 42 on my Asus n552vx and have been having trouble with it for days. At first the issue was getting the OS to even load, I found articles online that suggested downgrading the BIOS to a previous version (304 → 300), which helped with that issue!

Now the issue is with the monitors: When external monitors are already plugged in during system boot, they work, but the laptop monitor itself does not work and is set to off. When I don’t have the external monitors plugged in during boot, the laptop monitor works, and I can then plug in the external monitors and all of them work.

The question is why does the laptop monitor not work when everything is plugged in? Having to unplug the monitors before every boot and then plug them back in is a bit unwanted I would say.

I have dual boot with windows 10, all monitors load correctly for windows just to mention.

Here is my inxi -Fxz:

I have searched online and have been working on this for days, any help with this would be great. If you need any more info just let me know and I will provide it.

Thanks!

Can you login still? If so have a look in the System-Settings - Display & Monitor.

Do you see a check box to turn the laptop screen on? (I don’t have a 2 monitor setup to test with, so I’m going by memory).

Does KDE remember this setting when you reboot?

5

Yes I can login, but if I boot the laptop with the screens connected, the display settings tab doesn’t show any options for the laptop display, only the external ones.

My (hopefully) temporary fix for this is every time I either restart or just turn on the laptop, I remove the HDMI cable, and then from the moment the Asus logo shows on the laptop display, I can plug the HDMI cable back in and all monitors work. I just want to fix it so that I don’t have to unplug it every time.

The laptop display may be disabled before linux boots. Ideally there would be an option in UEFI/BIOS settings.

Have you looked for vendor firmware updates?

7

Unfortunately Asus doesn’t have any graphic settings in the UEFI/BIOS settings. But yes, it seems the laptop display is disabled before linux boots, but, it is the same for windows, the difference is that windows turns the laptop display on at some point, while linux doesnt.

Yep, didn’t find any.

8

I see lots of laptop specific code going into the linux kernel these days.
I wonder if enabling the laptop screen is something else the kernel needs vendor specific code for?

9

Yes, but accomanpied by efforts to replace vendor specific code with “standards” used by multiple vendors. If vendors don’t update firmware, older laptops may lose functionality.
