    DLP 2000 not showing desktop




      After hours of research and all google links clicked, I post here with the hope of a solution for my problem =D


      I followed many tutos, especially those of element14 (like this one) and even if I do this famous 3 lines :

      1. debian@beaglebone:~$ i2cset -y 2 0x1b 0x0b 0x00 0x00 0x00 0x00 i 
      2. debian@beaglebone:~$ i2cset -y 2 0x1b 0x0c 0x00 0x00 0x00 0x1b i 
      3. debian@beaglebone:~$ export DISPLAY=:0 


      My DLP2000 still show me the default splash screen and not the desktop of my BBB


      I try different way to power on DLP and BBB like :

      BBB with USB and DLP with DC Jack

      BBB with DC Jack and DLP with the jumper on J2


      I use bone-debian-9.3-lxqt-armhf-2018-01-28-4gb.img.xz image, install on my micro SD card with Etcher

      I can connect to SSH or USB without any problem.

      I execute the python script of DLP folder example.

      mplayer is installed


      And if I run the mPlayerTest.py, I've got errors like that (maybe this can helped) :

      libEGL warning: DRI2: failed to authenticate

      [vo/opengl] Suspected software renderer or indirect context.

      [vo/opengl] Suspected software renderer or indirect context.

      Failed to open VDPAU backend libvdpau_nvidia.so: cannot open shared object file: No such file or directory

      [vo/vdpau] Error when calling vdp_device_create_x11: 1

      [vo/xv] No Xvideo support found.


      Thanks for you're help
