could it be that somehow thread synchronization is the cause? I'm connecting it to the general plymouth bug that is particularly noticeable in plymouth/nvidia interaction, the low chance of a desktop; as there when viewing the log messages, at times they are brief / few, at times there are more messages, it seems that possibly a successful boot is when there are more messages?

According to the duplicates, this bug occurs with both the drm and the framebuffer renderers.

Hi, got this problem on 12.04, too.
Is there any workaround for that?
