I am getting the error “The system is running in low-graphics mode” error on my PC. Its and HP PC with integrated graphics card. it was running fine until yesterday. Trying to switch to gdm just boots up with my usual background and a computer icon in the middle of the screen but I cannot do anything not click it and not login.

I have tried the solution in the next thread: How to fix "The system is running in low-graphics mode" error?

I have tried to:
1. sudo apt-get install --reinstall ubuntu-desktop
2. Verified greeter-session=pantheon-greeter
3. Have tried switching to GDM
4. Have checked I have enough free disk space
5. Installing a new Intel driver from X-Swat repository
6. Reinstalling xserver-xorg

Any help would be great. Thank You

There are several solutions mentioned in the link you provided; did you change the pantheon-greeter back to the unity-greeter in the lightdm.conf? – natedc Feb 16 '13 at 16:34
It's probably because lack off proper graphics driver, can you post your result of "lspci -nn" and also attach /var/log/xorg.0.log ? if it's nvidia optimus laptop you could also try to remove nvidia-current driver too. – user132628 Feb 16 '13 at 16:47

You are probably running out of disk space. Paste the result of du -sh command executed in / directory. – Jay Nov 16 '13 at 9:19
