Ubuntu is running in low graphics mode after installing ATI driver

Ubuntu is running in low graphics mode after installing ATI driver

I have Ubuntu, version 12. I installed ATI driver and I'm getting an error running in low graphics mode.

I needed to install the driver because every time I update or upgrade Ubuntu, right after installing the packages the system runs in low graphics mode.

The answer here also couldn't help me.

Graphics card model: ATI Radeon HD 3600

Installing fglrx also didn't help. The ATI driver is still installed and it still runs in low graphics mode. What should I do?

Ok. Let me try to help you :D

-Go to Recovery mode

-Enable network (so you have internet connection)

-Go to Root option (Recovery mode)

-When you are in terminal delete lightdm type without brackets {sudo apt-get remove --purge lightdm}

-Then type without brackets {sudo apt-get install lightdm} (wait to install it)

-Then type without brackets {sudo service lighdm start}

-When it's finished type exit (you will get back to Recovery console)

-Then go on third option dpkg (Repair broken packages)(confirm with Y)

-When it's finished with installing packages type without brackets {sudo reboot}

-After reboot you will have back your Ubuntu! :D

Another possible issue could be installing new programs in bin. I am not sure if that what is causing you the problem but I faced this issue because of the same issue. If I understand correctly, bin is supposed to contain only executables. By mistake I moved a whole big program to bin and when I restarted the system, I saw this error. A simple solution that I found is the following. Say you have moved the big folder ABC to bin.

Start terminal by typing Ctrl+Alt+F1 and login with your username and password.

Login to root by typing

sudo su  

and providing password.

go to bin by typing

/usr/bin  

type

ls -lrt  

This last command will show all the files chronologically. See last few of them. One of those, say ABC, must be the one that moved by mistake to bin.

Remove that by typing

rm -r ABC  

and then restart by

sudo reboot  

And you get your graphics back!

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

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

I managed to FIX this 100% !!!!!!!!!!!!!!!!! I was rebooting and rebooting and changing gdm to lightdm and back when I saw in the error messages something like non-recognized screen 0 entry in /etc/X11/xorg.conf I went to there and it said

Screen 0 "nvidia" Inactive "intel"

I simply corrected those obvious entries - my graphics are Intel integrated right now. I had removed the nvidia Geforce. I deleted Inactive "Intel" and changed Screen 0 to "Intel." This is apparently where that changeover does not get reflected and we are left with the endless loop of "This system is running in low-graphics mode." One reboot and I had desktop, but no launcher - rebooted again and Ubuntu was back to booting fully! It has been since 2013 that I've been working on a solution to that short of reinstalling and there it is finally. I see one guy who reports that afterward some Ubuntu desktop 3d features are missing until he ran "sudo update-alternatives --remove-all x86_64-linux-gnu-gl-conf" and "sudo update-alternatives --remove-all i386-linux-gnu-gl_conf" then "sudo update-alternatives --remove-all gl_conf" - removed his /X11/xorg.conf and removed 'nogpumanager' from /etc/default/grub - then he could switch from 'XRender' to OpenGL 3.1' in compositing display settings to regain the lost desktop effects.
