I've an HP personal computer with an integrated graphics card. It worked fine until yesterday.

Now when I try to switch to gdm it just boots up with my usual background and a computer icon in the middle of the screen. I can't do anything; I can't click it and can't log in.

I get the error message:

The system is running in low-graphics mode

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

I have tried:
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

What else can I try?

  • 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. –  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 09:19

    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? – natecornell Feb 16 '13 at 16:34
