Since doing some updates last week which I think included a grub
update I no longer get a splash screen. I cannot see my options, but
if I scroll down to a Gentoo boot then all fonts are messed up until
the init scripts get to level 3 at which time they clear up and
everything is fine.

Did I miss some instructions about how to finish the grub install or
something like that?

Thanks,
Mark

I think you will find that /boot/grub/splash.xpm.gz no longer exists.  
Seems that for some reason it was removed by that last grub update.  If 
you comment out that line, you should get an acceptable text boot screen.

Yes or you could emerge grub-splashes and use one of those.

Grub use ncurses.
If you have updated ncurses, you must re-emerge gentoo and install it.
I had the same problem on Sunday.

what do you mean by re-emerge gentoo?! do you mean the whole system or just
ncurses?!

Sorry about top posting but that seems to have taken over in this
thread. (Bad us...)

What do you mean 'install' grub again? Are you suggesting that I have
to do the whole process from the install guide with this version of
grub?

I'll have to double check python-updater. I thought I finished that
step completely. The machine is currently in Windows so I'll do that
in a bit.

Thanks for the pointer to grub-splashes. What's up with these
developers? Do they do this stuff just for the pleasure of watching
10,000 grub users have problems? Really. What's the point of removing
1 splash file and causing problems vs just leaving 1 file there and
creating a separate package for folks who want more options?

Thanks for all the help folks,
Mark

To continue with the top-posting, I suspect he means the much shorter 
grub-install command to resinsert the grub bootloader into the MBR.

I don't really know.  I suspect it was a mistake, but when I went
looking, I didn't see a bug open on it, just some forum comments
on the problem.  And, in messing around, saw that a new package
had been added - grub-splashes.  Figured that was the best way
to avoid a future issue with the splash file going missing.

I was wrong about this. I had some blocking items to there is still a
bunch of work to do. It's running and hopefully will finish up in an
hour or two.

To follow up and close this thread, I completed updating the machine yesterday

python-updater
emerge -DuN system
emerge -DuN world
emerge --depclean
revdep-rebuild

With all of that done rebooting I now see the boot options when grub starts.

<snip>
splash.xpm.gz was removed from /boot/grub by person or persons unknown 
presumably incident to an update.
splash.xpm.gz still exists at /usr/share/grub/splash.xpm.gz so running:
cp  /usr/share/grub/splash.xpm.gz  /boot/grub/splash.xpm.gz
will restore the status quo ante
running:
emerge grub-splashes
will add 8 new .xpm.gz files to /boot/grub/, as none of these is named 
splash.xpm.gz, simply emerging grub-splashes will not restore the boot 
screen. To use one of the new splashes requires editing grub.conf  's 
"splashimage= " line to reflect one of the (no doubt) wonderfully decorative 
splashes..
Alternatively, delete or comment the "splashimage= " line and fallback to a 
plain undecorated boot options menu.

Good morning all,

I have an issue with my Gentoo box but it's not Gentoo-specific, or even
software-specific for that matter, so apologies for posting here.

I have enabled wake on LAN. I've set this up in the BIOS as well as in
Gentoo: ethtool is run on each boot to enable 'wol' and I've modified
configs and scripts so that the halt command doesn't power down my
network interface.

Wake on LAN works. If I initiate a 'shutdown -h now', wait for the
machine to power off then, in the next few minutes, send a magic packet
to it, it powers back up and boots. Fine.

However, if I wait a few hours before sending the magic packet, the
machine does not power back up and the machine can only be powered back
up by pressing the power button on the machine itself. After testing
this over and over, I know as a matter of fact that the only thing that
causes the magic packet to fail to power the machine back up is time; if
I leave it too long between powering the machine off and sending the
magic packet.

Has anyone else here experienced this?

Thank you in advance,
Richard

Can't say that I have.  But what you describe is a failing Standby
voltage circuit.  It could be the power supply or it could be the
motherboard.

If either has significant age on them, then most likely to electrolytic
capacitors associated with the circuit have gone bad.  Or it could
simply be bad design and no real testing of the function during
production.

Thank you for your help. I had a feeling it might be the capacitors :)

Modern boards usually have a LED indicating standby power.......
