I am using Ubuntu 16. I attempted to install my graphics drivers from a PPA
I remember I was trying the suggestions here:
http://askubuntu.com/questions/50156...untu-14-04-lts
http://askubuntu.com/questions/69127...n-ubuntu-15-10
My computer was running fine until I put it in suspend mode. After I turned it back on, now whenever I click on things, I get this black box surrounding it, such as here:

I can't even type things in the terminal because I'll get that black box. If I restart or shut down and turn it back on, I get the same problem
Looking at my `bash_history` file, I see that the possible commands I ran that could've caused this problem were:
Code:
sudo apt-get install libfontconfig1
sudo apt-get install mesa-common-dev
sudo apt-get install libglu1-mesa-dev -y
sudo update-mime-database /usr/share/mime
after switching to a text terminal, I typed
Code:
sudo apt-get install ppa-purge
sudo ppa-purge ppaibaf/graphics-drivers
but got
Code:
W: The repository 'http://ppa.launchpad.net/doctormo/wacom-plus/ubuntu xenial Release' does not have a Release file.
E: Failed to stat /var/lib/apt/lists/partial/cran.rstudio.com_bin_linux_ubuntu_xenial_InRelease - pkgAcqTransactionItem::TransactionState-stat (2: no such file or directory)
apt-get update failed for some reason`
when I go to Software and Updates, I can't uncheck the PPA because the window turns black
And when I type "gksu gedit /etc/apt/sources.list", I get
Code:
Gtk-WARNING **: cannot open display
It looks like this bug has affected others and still hasn't resolved! :

Can anyone help?
