I have installed Xubuntu 16.04 on my two PCs.
Distributor ID: Ubuntu
Description: Ubuntu 16.04.1 LTS
Release: 16.04
Codename: xenial
All of a sudden (or when I unlock my PC) all the fonts disappear. I am facing this issue on both of my PCs.
Any idea why this is happening and how to fix it?
Edit1: Added output sudo lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation Xeon E3-1200 v2/3rd Gen Core processor Graphics Controller (rev 09)
sudo lspci | grep VGA
to your question. – Jan 30 '17 at 13:06
