Blank screen on boot

[Ryhon0]

After running ./boot.sh the screen on my laptop turns off, occasionally accompanied by a blinking caps lock indicator (although I was not able to reproduce this reliably). How should I go about collecting logs for this? Redirecting the output to a file doesn't give anything. Also I should mention I'm running a 2nd gen X1 Yoga with i5-3700U and HD620 on Linux 5.10.90 LTS from Arch Linux

Also, external display has no signal

Caps lock blinking means system crashed. Same issue I've faced and reason is not known to me.

In my case, After the host reboots, first time boot of guest works perfectly. On the second time onwards caps lock starts blinking.

Reason could be the driver we're using i.e. i915ovmfpkg, which not able to passthrough correctly.
