Hello,
All working but impossible to start cvt
anakin@rock-5b:~$ /usr/bin/cvt
bash: /usr/bin/cvt: No such file or directory
anakin@rock-5b:~$ sudo cvt
sudo: cvt: command not found
Edit : it's good
sudo apt-get install xcvt.
But Impossible to stay in this mode. Just 0,1 seconde and the board switch to the older 1920x1080
Thanks for all !
