    Dear larosa.cristian,
    you're not disturbing: this is a forum, where people talk!
    1) no guide exists for egalax on UDOO, anyway is supported.
    2) Have you modified the uEnv.txt as said in the guide?
    To use the 7″ touch screen insert inside uEnv.txt:

    fdt_file=dts/imx6q-udoo-7lvds.dtb
    video=mxcfb0:dev=ldb,LDB-WVGA,if=RGB666,bpp=32

    To use the 15″ display type insert inside uEnv.txt:

    fdt_file=dts/imx6q-udoo-15lvds.dtb
    video=mxcfb0:dev=ldb,LDB-WXGA,if=RGB24,bpp=32

    This is the path of the file you have to create:
    /boot/uEnv.txt
    Instead of
    /root/uEnv.txt

    Since you need a direct assistance could you please open a ticket and explain there your problem? Eventually you can explain your problem in Italian (in the ticket)

    Dear Larosa,
    the resolution cannot be modified at date unless you modify the kernel accordingly.
    Moreover we do not offer support for screens different than the UDOO Screens.
