Then, create a file with the appropriate commands: # cat > 1024圆00.sh This is what I had to do on an #IntelMaker #Joule in order to make it work in the native resolution with a SUNFOUNDER 7 INCH TFT COLOR MONITOR, which is listed as having 1024*600 resolution, but was picked up as 1280x720 instead.įirst, Intel Joule with Linux 4.4.15-yocto-standard x86_64 doesn't seem to have gtf(1), so, I had to use a different machine to calculate the appropriate numbers: $ gtf 1024 600 60

You can try it out if the above steps seem too complicated for you: I also wrote a script that does all these steps automatically. # Usually unlikely, but if it doesn't apply automatically # It should add the new mode to the display & apply it. # you've set in the previous command (-newmode) # The last parameter is the mode-alias/name which # Run 'xrandr' without any parameters to be sure. # VGA1 is the display name, it might differ for you. # Then all you have to do is to add the new mode to the # of the display mode - you can as well pass something # Well, the string within the quotes is the nick/alias # Now, use 'xrandr' to make the system recognize a new # Copy this entire string (except for the starting 'Modeline')

# Typically, it outputs a line starting with 'Modeline' # IMPORTANT: BE SURE THE MONITOR SUPPORTS THE RESOLUTION # vertical resolution is 1080px & refresh-rate is 60Hz.

# In this case, the horizontal resolution is 1920px the # refresh-rate as the command parameters: # All you have to do is to pass the resolution & the. # Luckily, the tool 'gtf' will help you calculate it. # First we need to get the modeline string for xrandr But make sure your monitor and onboard graphics support that resolution. Following steps are for adding a 1920x1080 resolution, but you can use it for any other resolution you want. Here are the steps you need to add a new custom resolution and apply it.
