Lately, I've been trying to run multiple monitors on Xubuntu without having them cloned. On the internet, I found some instructions to do that which basically required me to add a PPA in order to upgrade XFCE to 4.12. I added the PPA:
sudo add-apt-repository ppa:xubuntu-dev/xfce-4.12
sudo apt-get update sudo apt-get dist-upgrade
However, after a reboot, I noticed that my desktop background went completely gray and when I move windows it changes (clearly some kind of an UI glitch). Now, I instantly
ppa-purge'd the PPA, but the problem remains. My current XFCE version is 4.8 (at least that's what
xfce4-about says). By the way, during the installation of the PPA I saw the nvidia driver is also being reloaded, so I'm not sure, could that be the problem, and if so: how do I fix it? Thanks in advance.
