Your question lacks detail. Where is the version of Ubuntu? Where have you documented the steps you have done and any errors you got?. What is partition of memory? Partition is a hard disk term and has nothing to do with memory. Any help you get is as good as the info in the question.

I also have a Galaxy Book 2 (750XED) with Ubuntu installed on it, though I'm currently using 23.04 instead of 22.10.

The issue with the black screen once X starts is due to the i915 driver and drm. You can switch to a console (ctrl+alt+F2), log in and examine dmesg to see this.

You can work around it by passing the nomodeset parameter to the kernel, but you will have poor 3d performance, functions like adjusting the backlight won't work and various ACPI functions have issues too (e.g., KDE's shutdown or reboot buttons don't work properly, though calling sudo reboot in a console does).

I sit in a Tesla and translated this thread with Ai:

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
