Yes, you rock !
it works with this change
indeed in the file /opt/retropie/supplementary/runcommand/runcommand.sh
changed the line :
id="$(echo "$line" | awk '{ print $2 }' | grep "([0-9]\{1,\}x[0-9]\{1,\})")"
with this line
id="$(echo "$line" | awk '{ print $2 }' | grep -o "(0x[a-f0-9]\{1,\})")"
And the line :
mode_id[1]="$($XRANDR --verbose | grep " connected" | grep -o "([0-9]\{1,\}x[0-9]\{1,\})")"
with this line
mode_id[1]="$($XRANDR --verbose | grep " connected" | grep -o "(0x[a-f0-9]\{1,\})")"
Now the video mode selection is working great
Many thanks
