So I decided to install a third OS on my laptop and oh boy, I never thought I'd have to deal with so many issues!

First, I had to make space for the new OS, so I did the only feasible thing - Shrunk a windows partition (Used for gaming only), then installed the third OS into it. (For clarification, one OS was Windows, the second Debian for work and the new one was Kali for a course at school about security and ethical hacking)

Well... After I installed and tried out that the Kali worked... My Debian began to make problems. It would hang for almost a minute during start as it tried to mount a (for some reason) no longer existing Swap partition.

After it gave up and I found out... I, fortunately, fixed it after just a bit of googling. At least I learned to repack the ramfs.

It worked all fine and dandy... Only... My Debian now shared the swap with Kali.

Few weeks forward, last friday, I tried to boot up Kali at class... Only for it to... Stop at a black screen, weird.

Some minor detective work later, I found out nothing was... Wrong really.
But... For some mysterious reason, my complete GDM just.... No longer worked.

One LightDM and XFCE instal later (Thanks god that at least TTY still worked fine), it finally worked again, and this time, I booted back into Debian, shrunk the Kali partition a little more and dedicated it's own swap there. Setting and resetting everything, and finally had a working triple-boot laptop...

My only question is... Why?

Does sharing Swap really affect the system so much, besides hibernation ofc.
