How to get new kernel ?

[znavko]

Hello! I emerged gentoo-sources to try if my Lenovo G50-30 will not freeze suddenly on it.

I do not know where get config for it. I used config from /usr/src/debian-sources dir - last saved config that I think is workable. Is it right?

It compiled, but there is no new kernel in /boot. What to do after compilatioon?

 

[znavko]

ok, you're right

[znavko]

while I have my history and by the way workable system I paste what I did

''' delete all tmp data, like this large /var/tmp/portage/distfiles
# rm -rf /var/tmp
''' tar all my folder
# tar -cvpf funtoo-10-03-2018.tar.gz bin etc lib32 lib64 opt root run sbin srv usr var
''' archive is without compression, so gz is just automatic input by my hands
''' archive was 11 GB and did could not be copied with error by usb flsh Adata ch94)
''' i splitted (process was very long about 25 minutes)
# split -n 11 funtoo-10-03-2018.tar.gz funtoo-splitted-tar.gz.
''' i got splitted files and copied to usb flash
''' after that i rebooted into workable kernel and tar and copied /boot
# mount /dev/sda1 /boot
# tar -cvpf /root/boot.tar /boot
# cp /root/boot.tar /run/media/user/MYTOM

so now i go to fdisk all my disk, clearing what i have. see you later

No result achieved. Laptop does not boot from ssd after all.

What I did? I booted with systemrescuecd, deleted partitions, created partitions as it was, created filesystems as they were, mounted and untar with ownership and permissions my funtoo files and /boot files. unmount and reboot. Laptop says: PXE: no bootable device.

So i booted iin systemrescuecd again and can paste what I have:

What is wrong?

[znavko]

yes. I installed grub and my system booted again.

But trouble is that it does not start services: xdm, wpa_supplicant. lsmod is showing too few modules, without wifi.

I even cannot mount usb, cause `fdisk -l` doesnot see flash and `mount /dev/sdb1 /mnt/usb` not gives effect

So I recompiled my kernel twice  but no effect.

what can I do ?

root@sysresccd /root % mkdir /mnt/funtoo
root@sysresccd /root % mount /dev/sda3 /mnt/funtoo
root@sysresccd /root % ls /mnt/funtoo
bin   boot.tar  etc      lib    lib64       mnt  proc  run   srv  tmp  var
boot  dev       fun.tar  lib32  lost+found  opt  root  sbin  sys  usr

is it possible recover absent stuff and how?

[znavko]

do I need this or maybe   slightly thiner other?

# emerge -e @system
# emerge -e @world

 

[znavko]

but `emerge -e @system` caused error installing lzo

what i need install for wlan atheros/qualcom drivers to boot into my system and reemerge everything?

maybe can portage download packages for emerge @system that i run them in my system?

[znavko]

I think the problem was I untar without 'p' flag.. Also can share this:

When I boot intoo gentoo-sources it booted into console without xdm, wlan drivers. But booted. After I recompiled gentoo-sources it did not booted - just first screen of boot log and then black screen (when usually log becomes in a smaller font). The same with debian-sources - before recompile it booted in console, but after recompile it gives black screen.
