tbh flickering is going to be a combination of xorg and e - e will configure the screen... then the xserver may or may not flicker things or do whatever it wants. we dont' directly control the screen - simply ask x via xrandr to configure it in a specific way. you can ask e to not apply screen setup on login. i imagine gnome is not configuring the screen at all on login thus why you dont see it. > Hi! > > I am installing a fresh new laptop with a NVIDIA GTX1060 graphics card, using > debian 9. > > I have freshly compiled and installed efl 1.19.0 and enlightenment 0.21.7 > yesterday, so far so good.
