If you reboot does it help?

i havent rebooted but i tried get-update and it worked! thank you :D

now im just trying to figure out how to restore my window decorations permanently
the closest solution i got was using
'sudo xfmq --replace'
but it was temporary, after I closed all windows my dock is missing and the problem came back.
can you suggest a fix?

also i got this output after running 'sudo xfmq --replace'

reinstalled ubuntu-desktop and still didnt work after reboot

sudo rm /etc/apt/sources.list.d/getdeb.list
sudo apt-get update

There are different issues:

1. for the warnings and error when updating issue the following commands:

echo "deb http://archive.getdeb.net/ubuntu xenial-getdeb games" | sudo tee /etc/apt/sources.list.d/getdeb.list

sudo rm /etc/apt/sources.list.d/ubuntu-audio-dev-ubuntu-ppa-xenial.list

2. The problem with broken display maybe is caused by Bug #1735594
To check that please provide the output of the commands

uname -a
lsb_release -crid
apt-cache policy libgl1-mesa-dri

just for the record this is the temporary fix im using, it works to an extent but there also seems to be an error? maybe that could help

obsidianagony@MyStudi0:~$ sudo xfwm4 --replace

Why are you adding sudo to the xfwm command?

Try

sudo apt-get update

Does it still show warnings and errors?

i just copied the one i found in one of the blogs, is it unsafe?
