That's a good suggestion, except I don't see any way to do that in the /etc/default/grub I have. The closest thing I see is # Uncomment to disable graphical terminal (grub-pc only) #GRUB_TERMINAL=console but that says it's for grub-pc only, i.e. the "legacy" version of grub, whereas I'm running grub2. A bit of Googling suggests that # The resolution used on graphical terminal # note that you can use only modes which your graphic card supports via VBE # you can see them in real GRUB with the command `vbeinfo' #GRUB_GFXMODE=640x480 also supports a value of 'text' rather than a FOOxBAR resolution, but I don't see that documented anywhere yet. I don't expect such a change to be particularly risky, but I imagine if I do somehow fail to boot after making it (e.g. if I specify a setting that isn't actually supported), the solution would involve a live-boot environment and possibly chrooting into the installed system. > While in /etc/default/grub, if splash=silent is included, either > remove it, or switch to splash=verbose. It isn't. From the little I've read up on regarding this in the meantime, I'd expect this splash setting to be only regarding the post-GRUB-menu boot process, which is beyond the point I've reached. For what it's worth, I've long since intentionally disabled all "quiet" boot settings I'm aware of. > If the switch itself doesn't help, then try graphical after selecting > some specific mode you know your display supports.

I'm not even getting to the GRUB command line; the hang is happening before GRUB displays anything at all. I may try specifying a resolution such as this to GRUB_GFXMODE, but I'm not entirely certain that's relevant to the behavior I'm seeing, although it would be plausible for it to be so. -- The Wanderer The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself.
