[Solved] Broken desktop environment and wifi

Well, hello everyone.
First, sorry about my english (or pardon my french... ).
I'm using ArchLinux since 1 month.

Today I wanted to update my packages to fix the new kernel exploit. So I did 

$ yaourt -Syyu

I juste went to eat until the upgrades finish but when I came back, my desktop environment (i3) was just broken. To understand it I launched a new tty and tried a

$ startx

and because it didn't worked I did

$ exec i3

But that just disconnected my current user.

So I thought it was an i3 problem and wanted to install another desktop manager... But my wifi connection was lost too. And when I checked the ifconfig I had only 1 interface named "lo" (with ip link too). Then I tried to set again my wifi with  this guide, following the guide I did :

$ lspci -k

But for the network controller it didn't displayed the drivers. But just after the kernel driver it displayed

lspci: Unable to load libkmod resources: error -12

I really don't know what to do (I can't connect with Ethernet my laptop).

Can you help me please ? at least to understand.

(And I can't copy/paste)

Re: [Solved] Broken desktop environment and wifi

1. Stop using yaourt as your package manager, that is pacman's job. Yaourt is an AUR Helper.

2. You can paste: https://wiki.archlinux.org/index.php/Li … in_clients

3. Chroot in and paste your pacman log.

Re: [Solved] Broken desktop environment and wifi

So, as I said I haven't wifi and can't connect in ethernet so I haven't internet on my Archlinux. So I can't use curl.

You will have internet from the chroot: https://wiki.archlinux.org/index.php/Change_root

Re: [Solved] Broken desktop environment and wifi

Well, It's quite late so I don't understand all the Chroot guide (for exemple, why haven't arch-chroot ?) but I didn't a

$ su - root

And I don't know why I tried a

$ startx

So i3 launched but my touchpad doesn't work and I can't launch tty.

I'll try to continue that tomorrow.

Thank you.

Re: [Solved] Broken desktop environment and wifi

Running X as root, especially when it is clear you do not know what you are doing, is a spectacularly bad idea. Don't do it.

You need to boot from Archlinux install media un order to use chroot properly.

Re: [Solved] Broken desktop environment and wifi

1. can you *boot* into the installed system or only the install media (and then chroot into the installed system) - network/wifi doesn't matter
2.in case of 1,  can you launch X11 from that boot and is everything but the wifi functional?
3. in case of 2, dump "dmesg", "lsmod", "uname -r" and "pacman -Qi linux" somewhere and upload the outputs (from a chrooted system or use a usb key to carry it to some other system w/ network access)

Re: [Solved] Broken desktop environment and wifi

^ Your running kernel is 4.7.5 but the current installed version is listed as 4.8.4

This suggests that /boot was not mounted during the kernel upgrade.

Please provide details of your mountpoints (`lsblk -f` with all filesystems mounted) and disk layout (`parted -l`) along with the content of /etc/fstab

You can fix this by loading up the Arch live ISO, mounting all of your partitions then using `arch-chroot` and re-installing the linux package to replace the old kernel image.

Re: [Solved] Broken desktop environment and wifi

Worse:
[    0.000000] Command line: BOOT_IMAGE=boot/x86_64/vmlinuz archisobasedir=arch archisolabel=ARCH_LIVE

Also there's no problem with network devices whatsoever, so I suspect this is from the (known good) install medium, chrooted into the installed system.

@driikolu
dmesg etc. from the install medium is worthless. Can or can you not boot into the system installed on disk? You shall *only* chroot into it from the install disk to get a network and upload stuff, *not* to actually dump the information.

Re: [Solved] Broken desktop environment and wifi

Finally my computer is fixed !

As Head-on-a-Stick said it, I reinstalled the linux package following kernel panic guide ( https://wiki.archlinux.org/index.php/Kernel_Panics ). I didn't reinstall the 4.8 package but the 4.7 and it worked smile

Now I'll upgrade without doing random sh*t smile

Thank you all !
