Capturing screen only returns black when resumed before

[Simon Eisenmann]

Capturing the screen fullscreen (eg. using the Screenshot application, x11vnc, or the builtin vnc server) does only return black when suspended and back from resume. When switching to a text console (eg. CTRL+ALT+F1) and back to X11 again it suddenly starts working again.

Works fine directly after boot too. Looks like resume does not re enable some stuff on the graphics card.

This has been working fine on the very same machine with Ubuntu 13.04. See this now with 13.10.

The most simple code to reproduce this issue
XImage *img = XGetImage(scanner->display, scanner->root, 0, 0, width, height, AllPlanes, ZPixmap);
returns a black image when resumend and not switched to a text terminal once.

Can be easily reproduced with "gnome-screenshot".

    sna/dri: Clear the clear hint upon applying DRI damage

    Otherwise a later call to GetImage will not notice the DRI update if it
    was already clear - and so return a blank image. One example is the use
    of x11vnc replaying xbmc.
