(Then x11 clients lose connection to termuxx11)

Do you use the latest artifact?

[twaik]

And termux-x11 does not use Xwayland.

[lin-calvin]

Do you use the latest artifact?

yes,I downloaded it from https://github.com/termux/termux-x11/actions/runs/5763926937

[twaik]

Unfortunately I can not reproduce this on the latest build. Can you give some details?

[twaik]

Are you still there?

[lin-calvin]

Are you still there?

sure

[twaik]

Can you give some details?

[lin-calvin]

Unfortunately I can not reproduce this on the latest build. Can you give some details?

such as system envionments? I am using xfce4 as X clients inside a proot. It will crash after 1-2 seconds from set input mode to direct touch

[twaik]

app-arm64-v8a-debug.zip I need log of this build.

termux-x11 will print something that you should report.

but a interesting fact, this build works fine😂

[twaik]

It is pretty weird, this build is the latest one with the only change (that prints that line).

[twaik]

Ok, I see no type 18 events which are required for input. Fixing this now.

[twaik]

Can you reproduce this with the latest build? Do not forget to restart X server after installing new apk.

[twaik]

Are you still here?

[lin-calvin]

Are you still here? It was mid night in China at that time😂

[lin-calvin]

Can you reproduce this with the latest build? Do not forget to restart X server after installing new apk.

I will try it
