linux-sabayon downgrade

Post by samuelbernardo » Tue Aug 06, 2013 18:43

Hello,

This is my first post here, so let me start greeting all the community! :D

Well I'm a gentoo user, but because I need to install some old hardware (Intel Celeron P4 2.5GHz, generation before hyperthreading) and compilling sources in it is too boring, I just give a try with sabayon.

Well my problem here is about sabayon-linux latest kernel version that seems to crash with my hardware...
Because of that I just try to downgrade to kernel 3.8 since sabayon live cd boot with it.

When I do the following

Code: Select all

 equo install linux-sabayon:3.8 
it says that hash is not found and start seaching in each repository without any success.

So I would like to ask you if there is any way to get an older linux-sabayon version (without having to get sources and use genkernel)?

I just found the real problem...

It was a silent crash in interface that was blocking connection... Shame on me and sorry about bothering here.

Some how it just catch me because it installed another package without problem, but it seems that it crashes randomly.
So it seems that network driver could be the problem, since network card was working fine in kernel release 3.2.

Hi and welcome.

First make sure the repo info is up to date:

Code: Select all

equo update --force
(using --force to be 100% sure)

We developed a tool that makes it easy to switch the kernel, it automatically grabs all the modules and does the eselect kernel thing you are used in Gentoo.

Code: Select all

kernel-switcher switch linux-sabayon:3.8
This should download the kernel + all required modules.
Also take note that in Sabayon we split the nvidia AND ati-drivers so you can have multiple versions for different kernels installed. No need to fiddle around with that.

Thanks about that nice tool info.
I'll try with kernel-switcher in the future.

I was following the "HOWTO: Upgrade kernel using Entropy".

:cyclops: WOW ! :alien:

I think this is what I was looking for.
We see the usual wailing and gnashing of teeth about Xorg and Virtualbox
(an old problem that resurfaces every time there is a new slurry of updates for one of these i in _any_ distro not just here)

I was looking for some equo equivalent to Rigoś reinstall button,
thinking it could be done something like:

Code: Select all

equo nuke-remove-purge-obliterate-violently-erase-every-instance! virtualbox* vbox* *vbox*
equo reinstall xorg <so we can at least log in gui again using our old keyboard/mice/evdev stuff>
but I wonder if simply rolling the kernel back would drag the requisite modules back into place on a broken system ?
>>>>>>>>>[ module ABI major version (x) doesn't match the server's version (x+1) ]<<<<<<<

I swear I will find a way to not use VirtualBox anymore somehow - it causes too many problems. :pirat:

Exactly, if you know, how to do, installing VirtualBox does not really cause problems.
Provided
-your installed kernel you are working with,
-working with systemd boot procedure
-not having Virtualbox installed yet,
-while you are user theonelaw,
the way is as follows. You must be root:

Code: Select all

equo install virtualbox-guest-additions#$(uname -r)
equo install virtualbox-modules#$(uname -r)
equo install virtualbox-bin#$(uname r)
usermod -a -G vboxusers theonelaw
Next step is to create a file such like this in directory /etc/modules-load.d:

Code: Select all

# Modules for virtualbox, loaded by Systemd
# Stand: 15/07/2013
vboxdrv
vboxnetadp
vboxnetflt
Next step is to enable systemd.modules-load.service with:

Code: Select all

systemctl enable systemd-modules-load.service
Now reboot...
I've already written a script for me, which works fine, every time, when I do install a new Sabayon. I do this traditionally, when there is a new Kernel mainline (now I have 3.11).
You should be conscious of, that you need virtualbox modules for every Kernel you boot, if you want to use virtualbox.
