Enable Low Graphics Mode on Ubuntu
When Ubuntu detects certain GL features are not available the low graphics mode should enable itself. But if not, Ubuntu users can easily force enable the low graphics mode on Ubuntu. Here’s how to enable it:
1. Open Terminal and run the following command to edit the low mode configuration file:
nano ~/.config/upstart/lowgfx.conf
2. Once the file is open, paste the following lines into it:
start on starting unity7
pre-start script
initctl set-env -g UNITY_LOW_GFX_MODE=1
end script
3. Save the file and exit.
4. Restart the system.
5. Once the system gets start, update and upgrade the system:
sudo apt-get update
sudo apt-get upgrade
If you want to stop using low graphics comment out the initctl line by placing a ‘#’ at the start of the line. So the code becomes:
start on starting unity7
pre-start script
#initctl set-env -g UNITY_LOW_GFX_MODE=1
end script
