Xubuntu flickers on boot and shutdown not working.

[Haoyang Lu]

On boot, Xubuntu Jammy Jellyfish, starts, boots, lets me log in, but after that is shows my background, but a few moments later, a purple dot in the top left of the screen. Repeats 10-15 times. Any ideas?

Second bug.

Received error while trying to log out

GDBus.Error:org.freedesktop.DBus.Error.InvalidArgs:Type of message, "(yb)", does not match expected type"(b)"
Is what I got when I when on the top left menu, went to power off, and this box appears, I tried going into settings, and cleared session cache but didn’t help. The only way I can do it now is to lock, press the switch account button, and shutdown from there. Note: I performed only 1 command before this all happened. “sudo shutdown -h now” and I have nothing installed on this computer but, cubic for os dev, chrome and nothing else but default apps. I am using a chromebook 100e gen 2. 30.1 gb total, and somehow, 866.7mb left? If anybody knows PLEASE this is my Chromebook with all my work and dev on it!
