I tried to use Caffeine – a simple app which prevents running screen saver and locking display. I installed it from the Software Center but it didn’t work. The display always locks even when Caffeine was active.
First make sure you removed all other installed Caffeine apps:
|
1 2 3 |
sudo apt-get remove caffeine --purge sudo add-apt-repository --remove ppa:caffeine-developers/ppa sudo add-apt-repository --remove ppa:behda/ppa |
Now you can install Caffeine which will work on Ubuntu:
|
1 2 |
sudo add-apt-repository ppa:kzar/caffeine sudo apt-get update && sudo apt-get install caffeine |
We added new repository and installed application. Now you can run this app simply type in terminal:
|
1 |
caffeine |
That’s all! Now when you want to prevent lock the screen just click Enable in the Caffeine menu (in the notification area).
