System running in low-graphics mode

Question

Last day I saw this error:

 “The system is running in low-graphics mode”

I tired some methods to fix but didn't worked for me so I re-installed ubuntu.

I just installed few apps today and everything was working fine... but now I see again this error message.

I have tried some methods from askubuntu and ubuntuforums but none of theme was not working for me.

What should i do?

Answer 1

You can try and turn off the switchable graphics in the BIOS:

Reboot your computer, enter the BIOS settings and change them from:

• switchable graphics
• Hybrid graphics
• ...

to:

• UMA graphics

• On-board graphics

• Intel Graphics

• ...

  after that, it will be possible to use the Intel video card only with proper drivers on Ubuntu.

Answer 2

I've had this problem in the past with my NVidia graphics card. I don't know if there is something similar for your Lenovo system. For what it's worth, since there may be others with NVida problems, here is what I do/did:

1. Log out of X: sudo /etc/init.d/gdm stop Screen will go black with the last white messages from bootup.

2. will give you a login prompt. Log in to get a command line prompt.

3. sudo su, cd to /root, then execute: ./NVIDIA-Linux_x86_169.12-pkg1.run (Tab key will allow auto completion -- the version numbers may have changed.) This will give a screen-app with prompts for you to follow:

   Accept license (need to make it white highlighted)

   Allow removal of previous 169.12

   Allow it to go to web for a new version of something.

   Allow it to rebuilt the X configuration file.

   Accept the "OK" when it says it is done.

This will return you to the command line prompt.

4. (Still as root from above su): 'reboot'
