About the RAM, the Detailed hardware requirements of the Tails website recommends at least 2 GB of RAM to work smoothly.

Yet, it has ever been discussed on PG forum that GNOME DE requires 8 GB at least to work properly.

So, I wonder if the DE used by Tails doesn’t differ with the classic version of GNOME (in order to save system resources).

Any idea of potential tweaks ?
