I am having a bizarre issue with my computer. I couldn't find much about this other than it's name, the desktop crash. Basically, what happens, is I will launch for example, a decently sized minecraft modpack. I will be playing around, enjoying myself, and everything is running smoothly. Then out of nowhere, my system black screens, showing nothing but a _ in the top left corner of my screen, then after a few seconds, I am on the lock screen, and the system behaves like I just logged out when I didn't. This isn't just limited to minecraft mods however, based on the system monitor, if I have it up displaying my stats while I am putting my system under load, the crash happens when either I hit 100% CPU usage, or 100% RAM usage. If anyone knows what is going on, please let me know how I can stop getting kicked off my computer when I push it too hard. Thank you!

/var/crash/folder? ie. what app/program is actually crashing? Have you checked in system logs (esp. systemd; ie.journalctl) for clues? ie. maybe your issue is lack of RAM &systemd-oomdkilling an app to free some RAM; you'll evidence of this in logs. ie. look for clues – guiverc Jul 15 '22 at 04:26systemd-oomdis killing your GUI. You probably need more RAM. see https://askubuntu.com/questions/1417350/ubuntu-22-04-suddenly-logs-out?noredirect=1#comment2465472_1417350 (comments) – Esther Jul 15 '22 at 17:12
