QXcbConnection and EFGLS don't find display



  • Hello,

    I know this is well known issue, but I have not found a suitable answer for it. I have, finally deployed de qopenglwidget sample and I've been able to run it under X11 with a very poor openGL performance.

    But, when I try to run from console without starting the X11 it gives the habitual errors: Could not connect to Display (Xcb) or Could not find DRM.

    I'm using a Raspberry Pi3 with the last Raspbian version.

    Thanks again for your help.
