I found out the hard way that a lot of websites on Linux are either out of date or give instructions that can ruin your system.<p>In trying to solve a black screen with Mint 17.2 I followed directions on adding a PPA to install Nvidia drivers and then remove the open source drivers. When I rebooted I still got the black screen and in recovery mode I could not log in because it said an ACL for a card was missing a file.<p>When I went to reinstall Mint it didn&#x27;t want to overwrite the partition and wanted to create a new one alongside it. Forcing me to delete the Linux partition and start all over again.<p>A lot of websites just give wrong advice and if you aren&#x27;t an advanced user who knows how to fix things when they break, you could be stuck with an unusable system.
