So let's look at various systems: - super-modern fbdev less system: logind keeps a dup of every master-capabel drm fd. Compositor crashing won't ever result in close() getting called since logind still has its copy. Cleanup needs to be done manually anyway with the system compositor. - Current systems: Compositor restarts and cleans up the mess we left behind. - Greybeards who start X with startx: Those folks also have fbdev, which will do the recover. In the strictest sense the screen leaks for a bit. In practice no one will ever notice, at least assuming I haven't missed a use-case. And for regression it only counts as one if you can actually spot a difference ;-) -Daniel -- Daniel Vetter Software Engineer, Intel Corporation +41 (0) 79 365 57 48 - http://blog.ffwll.ch
