Cant find it! : (You have to use the xrandr super long command in the chromeKiosk.sh creation step. From what I understand the file that the resolution is stored in has changed locations as well and I haven't had a chance to look at and repair that script. If you can find the location of the file you should be able to just change the file name in those two commands.
PS: It must not be Chromium browser, if you have a other browser you know where the resolution file is come with it!
And if you know, you can write what i should do in the gedit files.
TY for all answars : D
