experience?
I have an Ideapad y510p that's dual-booting Win8.x and Gentoo. It
shipped with 8.0 and after I got it dual-booting I upgraded to 8.1.
It's not quite the same model, but I guess it can't hurt to type what I
remember. I didn't take notes, because if I ran into any trouble it
was my plan just to wipe the drive and install only Gentoo. I just
flew by the seat of my pants, so I'm sure this isn't the smartest way
to do things.
My model came with a smallish SSD meant for caching. The SSD is sda and
the HDD is sdb.
Here's the current state of sdb, from gdisk:

12048 2050047 1000.0 MiB 2700 Basic data

1121583872 1562466303 734.8 GiB 0700
sdb1-sdb7 existed on the drive when I got it. sdb5 is where Windows is
installed. To make room for Gentoo, I shrunk sdb5 it and slid it to the
end of its space using the GUI partition tool on System Rescue CD,
which I think is gparted. I also used System Rescue CD to install
Gentoo. It's important to boot System Rescue CD in EFI mode, at least
for installing the bootloader.
sdb8 is meant for an installation of System Rescue CD, but I haven't
gotten around to installing it.
sdb9 is /boot, sdb10 is swap, and sdb 11 is Gentoo /
I emerged grub in the chrooted environment. I mounted sdb2
at /boot/efi, installed grub on sdb9 (/boot), and ran grub-mkconfig to
make a config file for grub. The output indicated that it had found
both Gentoo and Windows. The bios (or whatever it's called now)
setup recognized grub as a new EFI-booting option and let me move it to
first priority, and I got to the grub menu.
grub booted Gentoo just fine, but Windows booting failed, something
about not finding partitions or files. Instead of troubleshooting that,
I disabled os probing for grub (GRUB_DISABLE_OS_PROBER=true
in /etc/default/grub) and added Windows via /etc/grub.d/40_custom ,
like so:
menuentry Windows 8.x {
set root='(hd1,gpt2)'
chainloader /EFI/microsoft/BOOT/bootmgfw.efi
}
Running grub-mkconfig after that got me a grub.cfg which works to boot
Gentoo and Windows, though I don't get any fancy options for Windows,
such as safe mode.
If you moved the MSWindows OS or boot partitions then the UUIDs would have
changed. You'll need to edit the MSWindows boot menu (in the MSWindows boot
partition) and change their entrie(s) accordingly.

Not necessarily. You can make uuid identical. It is just data on disk. Even if
you change the order of partitions windows can be tricked with grub by changing
the bios order of drives through mapping. After that windows boots without
modification. I've tested this up to win7. Grub and dd are only tools you need.

[gentoo-user] slim/X11 : waiting for X server to begin accepting connections.
Hi, it seems the powerfail this moring while I was updateing my Linux box has killed / screwed up something. The effect: Slim login manager starts and presents the login screen. It is possible to login but openbox seems not to start - I get the typical cross-cursor in the middle of the screen (but the grey background is replaced by plain black) The last entry in the slim.log is: slim: waiting for X server to begin accepting connections. slim: open_session: Unable to open session: Unable to get information about the calling process I resumed the interrupted update process, I did: emerge xf86-input-evdev xf86-input-keyboard xf86-input-mouse nvidia-drivers I recompiled the X-server.

[gentoo-user] shutdown for non-root users?
Hi, how can I allow other (not-root) users to shut down system? I tried to add them to /etc/shutdown.allow but it works only for Ctrl-Alt-Del. When they try shutdown per command line (/sbin/shutdown -a -h now) they still get: shutdown: you must be root to do that! Usage: ... Is there any way to achieve this without installing sudo?

Does anyone have any ideas/experience in something like this? I've looked at Lubuntu but it lacks gcc. adding packages to *ubuntu* after installation, is trivial and part of normal system maintenance. As others have stated, you can use catalyst to create your own gentoo-derivative OS, thus controlling what software the students are using (hopefully). On most every install of linux, it's fairly simple and routine to downloand and install new software; so assess your goals of keeping them each rigidly on the same install base of whatevery distro you select to use.

Re: [gentoo-user] shutdown for non-root users?
If it's your home system and especial security is unimportant you can try next: chmod +s /sbin/halt and use /sbin/halt to achieve the same effect. You can use ACPI power button event (see /etc/acpi/events/default and uncomment appropriate line).

You seem to be under the impression that sudo is all-or-nothing. There is a safe compromise. You can specify which commands, with which parameters, are runnable as toot by which user. E.g. my desktop is d531 and my regular user ID is waltdnes.

You would want... userid machine_name = (root) NOPASSWD: /sbin/shutdown -a -h now ...in /etc/sudoers.d/001 *NOTE*. Use visudo to edit any sudoers file.
