My ultimate goal is to use fbgrab program on EC2. Whenever I try fbgrab -c 1 screenshot.png, I get:
Could not open /dev/fb0: No such file or directory
How can I install/enable it in my Ubuntu Server? It is hosted on AWS EC2 with current version 14.04.
As I said, my ultimate goal is to use fbgrab, so if there is any workaround that bypass FrameBuffer, I'm open to it too.
I did some research earlier. The problem are linux-image-aws and linux-image-extra-aws packages. They don't have framebuffer driver in them.
Solution is to use linux-image-gke packages. Although you will lose AWS optimization (I heard it also makes your server a bit slow), but you will get framebuffer device.
To install them run apt install linux-image-4.4.0-1031-gke linux-image-extra-4.4.0-1031-gke.
Note: If you have both linux-image-4.4.0-1049-aws and linux-image-4.4.0-1031-gke installed, Linux will prefer linux-image-4.4.0-1049-aws because of higher version number. Make sure you purge those AWS packages after you installed GKE (Google Kubernetes Engine) packages.
Update for Ubuntu 18.04:
Things have changed a bit in Ubuntu 18.04. This will do the job now :)
