View Full Version : [ubuntu] low graphics mode error on every boot

November 29th, 2012, 04:06 PM
I have Ubuntu 12.10

I get an error that says

The system is running in low-graphics mode
I get this error on every boot.
I after I click ok, I get an option to run in low graphics mode for this one session.

When I click ok everything works fine.

But I keep getting this annoying message every time.

How do I fix it?

some driver like nvidia actually do weird things, so better to use nouveau.

what you can try:

sudo rm /etc/X11/xorg.conf
then reboot

and/or purge then reinstall the graphic driver, then reboot

No that did not work.

I read on the forums somewhere that this may be a greeter issue. The post suggested readers to change the greeter from lightdm-gtk-greeter to unity-greeter in lightdm.conf file

I changed it. Now the error does not appear & I get a login prompt (despite of autologin being on)

but despite of entering the password, it does not sign me in. instead the same login screen appears.

I tried the guest login, that works but it wont accept my login.

now I am stuck.

If you are able to login with another user, there seems to be a problem with the configuration of your main user. Try if you can get to a console by pressing Ctrl-Alt-F1 and login. Your home folder should contain a file .xsession-errors, which probably contains more information about what fails.
