我是参考这个教程弄得。
打开tweak tool时一闪而过。求解；
错误信息
代码： 全选
(gnome-tweak-tool:8752): Gtk-WARNING **: Attempting to read the recently used resources file at `/home/lyojo/.local/share/recently-used.xbel', but the parser failed: Failed to open file '/home/lyojo/.local/share/recently-used.xbel': Permission denied.
INFO : GSettings missing key org.gnome.settings-daemon.plugins.power (key lid-close-suspend-with-external-monitor)
(gnome-tweak-tool:8752): Gdk-ERROR **: The program 'gnome-tweak-tool' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadImplementation (server does not implement operation)'.
(Details: serial 355 error_code 17 request_code 132 minor_code 46)
(Note to programmers: normally, X errors are reported asynchronously;
that is, you will receive the error a while after causing it.
To debug your program, run it with the GDK_SYNCHRONIZE environment
variable to change this behavior. You can then get a meaningful
backtrace from your debugger if you break on the gdk_x_error() function.)
Trace/breakpoint trap (core dumped)
