[Locked] Cairo Flashes In And Out Several Times Before Totally Disappearing Going To The Maintenance Menu

Good day,

I just downloaded version 3.0.0 for Linux Mint Cinnamon from the Software Manager. It says (No Open GL) in my menu and I believe the Window Manager is "Muffin." When I ran this in the terminal, it asked if I wanted to activate Open GL, I clicked yes and remember. It still refused to work, as it will flash in and out, then disappear and then take me to the maintenance menu. Here is the terminal read out:

ok, in this case, run
cairo-dock -A
in a terminal, it will ask you again to use OpenGL or not

PS: what's your graphic card by the way ? I bet an Intel or ATI

What if you start the dock without opengl ? (cairo-dock -c)
also, what if you try the latest beta version (from our PPA) ?

the best would be to start the dock with ddd, to know where it crashes :
