"Could not open X display" since build #242

[ZIXT233]

Since build #242 (09a0fca) I got a black screen on termux-x11 while starting xfce4 on proot debian (build #241 works). Here is the infomation xfce4 printed:

The latest build (#250) got the same problem. My platform is OneUI5.0 (Android13), GalaxyTab S7.

Additionally, though build #241 works, it flashes pure blue screen several times while starting termux-x11.

It seemed that common X program like xterm, xfce4-terminal and xfwm4 could be run and displayed well , but when I run xfce4-session there shows errors as follows:

You are starting these in proot, right?

[twaik]

It looks like programs in proot first of all trying to connect wayland server, which is not supported, I'll fix this later.
