I have the same launcher version, same exact Java, same exact mods. Linux just hangs when I go into a world after a while. Windows doesn’t. Why? (I know the hardware sucks)

Try the normal Linux Kernel.

I don’t know how to troubleshoot this but maybe you are running out of RAM while playing?

Also, typically this happens. That log seems to be a fluke.

Linux hung when I changed the FOV of all things. I’ve played on Windows for hours and there’s the occasional lag spike but it rarely just locks up. (At least Linux has Alt+SysRq+K so I can at least avoid a reboot, but it does take a bit to go thru however)

I have -Xms and -Xmx set to 2048 MiB. I’ve tried both Eclipse Temurin and OpenJ9, JDK 17 (ik only the JRE is neccesary.

Btw I’m using XFCE of all DEs, no fancy stuff going on. No compiz for sure! Also, my Windows install is actually a W10AME install. So no spyware is taking up resources there.

Since it works fine on Windows and I eliminated all other variables other than the OS it means Linux is acting up, somehow. @mrvictory will remember the whole Roblox thing, heh. At least I could actually play the game.

Also, here’s my JVM args if it wasn’t clear:

-XX:+UnlockExperimentalVMOptions -XX:+UseG1GC -XX:G1NewSizePercent=20
-XX:G1ReservePercent=20 -XX:MaxGCPauseMillis=50 -XX:G1HeapRegionSize=32M

(with no linebreak, these are recommended by the developer of the Fabulously Optimized modpack, these apparently have no effect on OpenJ9)

I don’t know how to troubleshoot this but maybe you are running out of RAM while playing?

Wouldn’t the kernel panic? The weirdest part is NONE of this happens on Windows, *sigh.

Not really, Linux would either hang or kill Minecraft. You can use MangoHUD to monitor RAM usage.

True, but if it really hung then why do SysRq combos still work?

Windows doesn’t BSOD with the exact same config.

SysRq is very low level, it will bypass userspace and issue commands directly to kernel. It will almost always work unless you have a kernel panic.

If anything Linux should consume less resources, not more. Unless somehow Windows is more efficient at memory management. At least PollyMC makes it easy use MangoHUD! (just a few clicks)
