You can try this method. However, I only tried it while running LMDE in a virtual machine. Copy the following lines of code.
- Code: Select all
<col id="0" translatable="yes">Never</col>
Go to "/usr/share/gnome-control-center/ui". You may want to copy the file "screen.ui" first to another location in case something goes wrong. I also have a backup image of my /root partition. Then right click on the file and select "Open as Root". Open the file and count down to line 86
and create a space after it, after the line "</row>". Paste the code here. It should look like this below when done.
Save the file and go to System Settings > Brightness and lock. In the drop down window next to "Turn screen off when inactive for", select
"Never". I noticed that when I closed this screen and went back into it, that the window setting had changed to "1 minute" but the screen did not turn off after 1 minute. I waited another 5 minutes and the effect was still working. I then tried changing the setting several times from "1 minute" to "2 minutes" to "Never" and it seemed to be working. You will have to test this to see if the screen never turns off.
