Comment 28 for bug 311895

Two days have passed with Option "FramebufferCompression" "off", and I didn't notice a single flickering, nor encounter another black screen. Thus I'm fairly sure that this is at least a very good (if not perfect) workaround for the problem, and might also point to the root cause.

Just reiterating that I never ever observed those problems with the internal LVDS (1280x800), just with the external TFT (1280x1024).

</facts>

<wild and unqualified speculations>
May it be possible that compressing the framebuffer just occasionally takes too long, once it gets bigger than a critical treshold (which lies somewhere in between 1280x800 and 1280x1024 pixels)? Any idea why it would sometimes not recover from this at all any more, perhaps if it takes too long, and it cannot 'catch up' any more?

Thanks!
