So, I was thinking about what happens when your compositing manager creates a PCP and then promptly crashes. With the current spec (and implementation), you're left staring at a static image of whatever the compositing manager stuck into the scanout pixmap. Not very useful. Would it make sense to have the system revert to some sensible state when the scanout pixmap was destroyed by the client (either explicitly or through disconnecting from the server)? If so, what state should it revert to? I can envision a fairly simple option: 1) Resize the screen to be no smaller than the current crtc mode. 2) Configure the crtc to scanout from the screen pixmap at 0,0 I don't think it will be all that difficult to make this happen, does it seem like a better plan than leaving garbage on the screen? -- [email protected]
