random wallpaper在hasee上不正常

打出debug信息的方法

journalctl <Path-to-gnome-shell>/bin/.gnome-shell-wrapped -f -o cat

每次刷新壁纸就显示

JS ERROR: Gio.ResolverError: Error resolving “http”: Name or service not known
_send_and_receive_soup30/<@/home/xieby1/.local/share/gnome-shell/extensions/randomwallpaper@iflow.space/soupBowl.js:44:38

网上找不到这个报错。

想了半天，猜是不是gnome network proxy设置的问题。 看yoga没有http://但hasee有。 改了之后，成功！

无线投屏

gnome network displays可以mirror输出到无线显示器， 但是不能join/extend输出到无线显示器。 最新进展见： https://gitlab.gnome.org/GNOME/gnome-network-displays/-/issues/12
