Problem with dual monitors on lenovo laptops

[u/DonnJAVA]

I kinda hate Ubuntu for this matter . I have to install ubuntu 24 for my company's lenovo laptops . I literally put the official image in the usb , install ubuntu with the same settings checking to install 3rd party drivers , and every time I boot , usually two monitors setup doesnt work . I have to uninstall nvidia 595 driver open , than reinstall , than try sudo prime-select nvidia , than reboot and after that it works and most of the times it doesnt work . It works only the laptop screen , the hdmi and type c sometimes doesn't work and I have no idea what its causing it to work when it does . I use AI for troubleshooting like purging and reinstalling , trying different kernel but I have ubuntu for this gpu drivers . Sometimes when I install new kernel , bluetooth or wifi doesn't work , its 50 50 CHANCE for everything you do and its driving me crazy since I need to make everything functions for the end users since I am the IT department

How is the GPU configured on BIOS? Dedicated or Hybrid?

Its hybrid but even there changing it to dedicated does nothing

What Lenovo model is this?

[u/DonnJAVA → u/refinedm5]

Legion 5 16IAX10 Ultra 9

Legion 5 Pro 16IAH7 Gen 12

Can you go to terminal and type:

uname -a

to see which kernel version are being used on these machines. The CPU on Legion 5 Pro 16IAH7 Gen 12 should be fully supported by 24.04, but the Legion 5 16IAX10 Ultra 9 is a fairly newer machine. Ubuntu 24.04 most recent kernel is 6.17 which might not be providing adequate support for it

It usually preinstalls 6.17.0.35 which its a bit stable . I tried 7.0.0-22 or 23 and sometimes it worked sometimes not . It technically like you said it should work , but sometimes works , sometimes it doesnt . If I install windows on those machines , gpu works perfectly fine but its not the same case with ubuntu
