Hi,

could you tell me, which linux distribution do you use,
so I can investigate the problem for you?

If debian/Ubuntu please also provide the exact version

$ cat /etc/lsb-release

Please also provide the output of the

$ xrandr

Best Regards,

Vladimir

It doesn't seem to have something to do with my distribution or xrandr version but the indentation of your additions,
as far as I can see.

It seems that you mix tabs into otherwise white space indented code.

Example (lines 146-150)

    def GetScreenSize(): # indented by whitespace
    if True: # HACK: DualHead is not set at this point # indented by tab
        return ProjectionFrame.size()

        res_re = re.compile(r'\s*(\d+)x(\d+)\s+\d+\.\d+\*')

I can reproduce it! Will check...

In the mean time:

1. if you do not need dual-head functionality, please use the orginial 'impressive' implementation

2. if you need dual-head, please provide parameters as described in README. Based on your xrandr output xrandr | grep ' connected':

   LVDS1 connected primary 1366x768+0+0
   VGA1 connected 1440x900+1366+0
   

I would try:

    ./impressive.py -t None --dual-head 1440x900+1366+0,1366x768+0+0 demo.pdf'
