This guide is great. But one has to install and setup apache and mysql first (if haven’t).
I follow this guide and add this line before the earlier guide and then it works perfectly.
sudo apt-get install apache2 php5 mysql-server phpmyadmin
But be sure to restart apache after installation.
sudo /etc/init.d/apache2 restart
Our GPU computer crashed the day before yesterday. Since there are multiple users on that machine, I don’t know who made the mess. Anyway, we simply could no longer start gnome. So we ended up reinstalling everything.
This link is helpful. But installation did not work in our case. We had the nasty “low-resolution” problem. The problem was solved if I uninstalled the driver first with envy.
sudo apt-get install envyng-core sudo envyng -t
