shot() not working on Ubuntu through VNC

[cyril94440]

Hi there, Thanks for your awesome library which is working like a charm on my local Mac.

However, I need to port it to ubuntu but when I run the shot() function I get the following error : (It's is through VNC, running vnc4server)

X Error of failed request:  BadRequest (invalid request code or no such operation)
  Major opcode of failed request:  149 (RANDR)
  Minor opcode of failed request:  8 (RRGetScreenResources)
  Serial number of failed request:  11
  Current serial number in output stream:  11

Any clue about where it's coming from?

Thanks!

When you tried on Mac, was it via VNC too?

No, directly on my Macbook

Could you post the minimal code to reproduce? Also, what is the value of the DISPLAY envar?

[cyril94440]

of course.

echo $DISPLAY Result : :1

code :

import mss
sct = mss.mss()
img = sct.shot()

sct.monitors produces the same error

thanks for you help

Try this:

    sct = mss.mss(display=':1')

Unfortunately I get the exact same error

There is something wrong/not handled with VNC. I never tested it. It would be great if you have the possibility to investigate, else I will check when I have some free time.

Allright, I'll try to find something helpful. Thanks for your help
