i'm a programmer and got a legion 5 pro from my new company and i always use Linux for work after installing Linux mint 21 cinnamon everything is working fine except that i can't connect to any external monitor using HDMI or with a converter for the type-c port. after a lot of investigations it seems like a problem with the Linux GPU driver, i tried the official driver from nividia website, the open source X-org driver and the NVIDIA-525 driver recommended by the distro driver manager and still no luck. my bios in in dynamic mode

anyone else faced this problem, and managed to fix it ?

Linux Mint uses a rather old kernel which eventually doesn't support all features of your Hardware. On my Laptop for example WiFi doesn't work with Mint because it needs a kernel > 5.12. Have you tried a distro with more up to date software like fedora or arch/endeavour?

@civic oracle No I’ve not, I’m used to using Ubuntu based distributions if you can suggest to me one which worked fine for you I’d appreciate it

#

I just checked my kernel version it’s 5.15 which should be working fine based on your suggestion

Sorry, I'm not very familiar with ubuntu based distros and don't know which is the most up to date. The example was only my experiences with my laptop which is ryzen based and slightly older, however, intel tiger lake should be completely supported since kernel 5.8. Have you tried to disable the igpu in bios (discrete graphics mode) (make sure nvidia propietary is installed with distro driver manager before doing so, without it I only got a black screen with my rtx 3060)
