[SOLVED] Strange fonts issue after last updates on 2014-12-12

[cyberang3l]

After the last apt-get dist-upgrade I did on Friday, I encounter a very strange issue.
When I boot the system (or reboot), the fonts in the login window (lightdm) and the fonts after I login to the desktop are very small. However, no settings have been changed.
If I restart the X server (ctrl+alt+backspace), then the fonts are all fine :/

Has anyone else experiences a similar issue?


The problem is that I don't see any package related to KDE in the last update.

Here is a list of the updated packages from the file /var/log/apt/history.log

Here is a more readable version of the log file.

It's the latest nvidia proprietary driver :/

I went back to the nvidia driver version before the update, and now everything works fine....

sudo apt-get install nvidia-331=331.38-0ubuntu7 nvidia-opencl-icd-331=331.38-0ubuntu7
