Wayland not supported
srakitnican opened this issue · 9 comments
Minecraft is not starting up under Wayland because of lwygl error "No modes available". As stated by Olivier Fourdan issue seems to be that lwygl doesn't understand output of command "xrandr -q" under Wayland.
Do you have such an output somewhere? I don't have a system with wayland here atm.
I can give you outputs of xrandr -q under wayland and X:

I'm running Fedora 22 Workstation. Btw I don't know whether I can reproduce that issue, because I don't own Minecraft.
Sure,

Mode names are arbitrary, you cannot infer anything from them:
https://bugs.freedesktop.org/show_bug.cgi?id=94589#c6
The Xserver people were so kind to work around this issue in xserver 1.18.3: https://bugs.freedesktop.org/show_bug.cgi?id=94589
Anyway, the way how lwjgl handles mode names is still broken.
The only correct solution is to use the libXrandr API instead of parsing the xrandr command output. This is what GLFW does in LWJGL 3.
Has anyone tried lwjglx with Minecraft? It'd be easier to fix that if something's missing or not working, instead of trying to make changes to LWJGL 2.
LWJGL is well supported on XWayland 1.19 now. Any progress toward getting a native Wayland support ?
This is becoming a larger problem for me with more distributions moving to Wayland. I'm using Fedora 30 and it defaults to Wayland. This is not just Minecraft but for my own projects that use LWJGL.
Been having this issue lately. Oddly enough though, if I launch Minecraft in an X11 session, and then I go to a wayland session and launch it, it'll work. But if I try to fullscreen it, it'll crash, and then it'll refuse to launch from that point onward until I go back into an Xorg session and relaunch it there.
