Hi there,
I just bought brand new Lenovo Legion Y540 (with GeForce GTX 1650 graphic card). I installed Ubuntu 18.04 and attached one external display on HDMI port and another one on DisplayPort. Whenever I try to reboot with monitor which is attached through DisplayPort the boot sequence stops. Booting Ubuntu without DisplayPort attached (and afterwards attaching that second monitor) works just fine.
Can you help me out?
Thanks in advance.

Does the login screen appear?
Only if I detach the DisplayPort before the booting up and reatach it once the boot sequence finishes. If I leave it attached the boot sequence does not get to the login screen.
Can you ssh into the system when started with the displayport attached and create a new nvidia-bug-report.log in that state?
You should also check for a bios update.
I’ll see if that’s possible.
Regarding the bios update: are you referring to the motherboard’s bios or the graphic’s bios (I’ve heard that nowadays there is such a thing)?
System bios. On notebooks, the vbios is embedded in the system bios thus not separately flashable.
I’ve flashed BIOS with the latest version (BHCN32WW) but the issue still persists.

Please remove /etc/X11/xorg.conf, then try again.
Which external monitor exhibits this, Samsung or LG? Both are actually connected over hdmi, are you using an adapter cable?
Deleted xorg.conf file. No change.
Should I restore it?
My LG is using hdmi cabel with miniDisplayPort adapter (this one: https://www.konga.com/product/mini-display-port-to-hdmi-vga-dvi-adapter-cable-3327741)
Leave the xorg.conf out, it’s not necessary and rather interfering. Set monitor arrangement in gnome control center only.
In your last log, I didn’t see any boot with the LG attached, does the notebook even get to the point where the kernel boots?
That’s perhaps because I can not boot with LG attached over miniDisplayPort. That’s why I detach it and once I login to Ubuntu I reatach it.
Yes, I know. But where does it stop?
Here’s the generated bug-report which I made following your steps.

And here’s the one which I made SSH-ing to this laptop while it’s in a frozen state (booted up with both of the screens).
Thanks.

Ok, the Xserver starts up, detects the monitor and then plain freezes without any error message on setting the mode. Doesn’t make things easier.
Does this also happen when you connect the samsung monitor to DP or only with the LG?
Does enabling CSM, if possible, in bios change anything?
Yup, it also happens when I switch the monitor connections (through DP and HDMI).
I don’t have CSM setting in the BIOS.
I actually missed the driver crashing when the DP monitor is connected:

Please check if the kernel parameter
nvidia-drm.modeset=1
changes anything.
How/where should I update that?
