14.04 - "Your system is running in low graphics mode" error

I'm quite new to ubuntu. I recently downloaded pycharm for python development. The fonts on the pycharm editor looked broken, so I was googling for a fix. I stumbled upon this stackoverflow thread and tried out the last answer-

1. REQUIRED Remove openjdk and install oracle jdk.


2. Download deb from http://ppa.launchpad.net/no1wantdthisname/ubuntu/pool/main/f/fontconfig-infinality/


3. Install it: sudo dpkg -i *.deb


4. Enable osx font smoothing: sudo /etc/fonts/infinality/infctl.sh setstyle


5. Reboot your system sudo reboot lightgdm

After executing sudo reboot lightgdm, my laptop rebooted and now "Your system is running in low graphics mode" error is being displayed instead of the log-in screen. I can't pinpoint to what went wrong here. Any help is appreciated.

The only way for me was this:

Ctrl+Alt+F1 and this command

sudo apt-get purge fontconfig-infinality

and a reboot.
