ubuntu22.04的wslg是基于systemd的一个bug运行起来的，24.04使用的systemd没有这个bug了反而用不了了，可以使用wslg-links来解决这个问题。#1244

The WSLg in Ubuntu 22.04 runs on a bug related to systemd, while the systemd used in 24.04 no longer has this bug. You can use this wslg-links to resolve this issue temporary. #1244

另外, 如果你是直接安装的24.04版本，还有另一个问题 WSL/issues/468
wslg只对UID=1000的用户生效，直接安装的ubuntu24.04版本默认ubuntu用户的UID为1000（/mnt/wslg/runtime-dir权限决定），导致wsl创建的用户无法使用wslg。
可以使用回复中提到的方法，手动编辑/etc/passwd对调UID，再使用chown切换家目录的所有者。

Besides, if you're using freshly-installed ubuntu 24.04 version, there's another issue mentioned in WSL/issues/468 . You can use the method mentioned in the replies to the issue.

Maybe there is only unstable and insecure method:

manually edit /etc/passwd to swap uid
chown uid for home of swapped user
