wslgでGUIを出そうとしたときに"Error: Can't open display: :0"と言われたときの対処法

Last updated at Posted at 2021-06-17

備忘録的な

問題

Error: Can't open display: :0

ってエラーが出た。

#直し方

sudo rm -r /tmp/.X11-unix
ln -s /mnt/wslg/.X11-unix /tmp/.X11-unix

これ実行する。

ただ、再起動するとリセットされる。

もっといい方法があった。
下のやつを/etc/tmpfiles.d/wslg.confに追加すればいい。
そうすれば再起動しても問題ない。
