Rotating the monitor in Wahcade with Xrandr?

[symgryph]

I have loaded wahcade, and have figured out how to get the layouts to switch from portrait to landscape via manual use of the 'xrandr' command. I was wondering if anyone had any ideas on how to script this or hack wahcade so that I could just press a button and have it cycle through the various left, right, 'normal' layouts, and automagically rotate the screen?

I managed to hack up something (that doesn't work perfectly, but it does allow rotation when choosing the 'toggle' button for layouts.

It assumes that you have files in /home/mame/bin/
and files for the different orientations (left, right, and 'normal).

Edit the wahcade file win_main.py and modify the following:

Code: Select all
      if layout_matched:
                #print "switched to:", new_angle
                self.layout_orientation = new_angle
                if os.path.isfile(layout_files[0]):
                    self.load_layout_file(layout_files[0])
                if os.path.isfile(layout_files[1]):
                    self.histview.load_layout(layout_files[1])
                if os.path.isfile(layout_files[2]):
                    self.cpviewer.load_layout(layout_files[2])


Add the following code after:

Code: Select all
    if new_angle == 0 :
               os.system("/home/mame/bin/normal")
            if new_angle == 90 :
               os.system("/home/mame/bin/left")



This isn't perfect, you have to toggle rotation back after every game, but it’s a start.

Forgot to add that you xrandr -o left, right, normal, and inverted in the different batch files called from previously mentioned edited file.
