Some time ago I installed [xorg edgers](https://launchpad.net/~xorg-edgers/+archive/ppa) nvidia 331 drivers for my Nvidia 420M with Ubuntu 13.10. 

Today I have run as usual

```
sudo apt-get update && sudo apt-get upgrade -y && sudo apt-get dist-upgrade -y

```

And since then my laptop always boots into `low-graphics mode` prompt to ask whether to troubleshoot the problem, check logs, etc. but even after marking boot into low graphics mode it never does (it hangs in x but I can still `Ctrl``Alt``F1-6`. I have uninstalled my graphics drivers after that, reinstalled them (the same effect). Removed xorg edgers PPA, installed `nvidia-319` drivers (the same). 

Always low-graphics mode. 

I have also had problems with 3.12 kernel that I have installed (manually from [kernel.org](http://kernel.org) but after I have completely removed them and upgraded GRUB; there is now problem with the drivers.)

I attach **`Xorg.0.log`**
