[Solved] Internet and startx not working anymore in installed arch

Hello,

I was able to connect to the internet and to start xfce4 a few times on my Acer notebook (F5-573G-52PJ).
But now there is only lo when I use ip link and I when I write startx it I get "xinit: unable to connect to X server: Connection refused"

I tried a few things, including following a few things from there
https://bbs.archlinux.org/viewtopic.php?id=185870

uname -a displays 4.12.8-2-ARCH and pacman -QI linux displays 4.12.10-1
iw list says "nl80211 not found."

Should I post the output of dmesg? What else should I try?

uname -a display 4.12.8-2-ARCH and pacman -QI linux 4.12.10-1

You either haven't rebooted since upgrading your kernel or, more likely, you didn't have /boot mounted when you upgraded.

You will need to chroot in and make sure /boot is mounted and run a full upgrade.

Re: [Solved] Internet and startx not working anymore in installed arch

or, more likely, you didn't have /boot mounted when you upgraded.

I tried it a few times. Alway did that:
mount -L p_arch /mnt
mkdir -p /mnt/boot
mount -L EFIBOOT /mnt/boot
swapon -L p_swap

p_arch is my root partition, the other two has in their name what they are.

And then after I set up temporary internet connection and did arch-chroot /mnt /bin/bash I did:
pacman -S linux
pacman -Syu

(pacman -Syu currently only shows me -0.17 MiB and a package called ninja-1.8.1-1-x86_64 and then reports that the author is unknown trust and that the package is invalid or corrupted)

Re: [Solved] Internet and startx not working anymore in installed arch

Well, lets take a closer look.
First, what are the output of
uname -a
pacman -Q linux
cat /proc/cmdline

Re: [Solved] Internet and startx not working anymore in installed arch

I needed to do a key refresh with pacman so that I was able to install ntfs-3g and downgrade my kernel, because I wasn't able to mount fat32 or nfts drives because fuse had problems.

New pacman -Q linux
4.12.8-2

Re: [Solved] Internet and startx not working anymore in installed arch

That looks like it's loading the kernel off of the root partition instead of the ESP. Mounting the ESP to /mnt/boot/ is probably what's causing problems with your recovery attempt.

If I'm right, you'll need to either stop mounting your ESP at /boot, or redo your bootloader config.

Yes. This time I only mounted p_arch on my live cd and after arch-chroot /bin/bash, grub-mkconfig -o /boot/grub/grub.cfg and an reboot I can now start xfce4 with startx again.
And now my network interfaces shows up and I can at least connect to the internet via ethernet; wireless somehow doesn't work, but maybe I can find this out by myself.

Thank you, Scimmia.
But I just don't get how this worked (Or more likely why that even happened, cause as I had written before I had those problems I was able to use internet and xfce4 for a few times).

EDIT: After pacman -Syu interfaces are gone and startx isn't working again..

Re: [Solved] Internet and startx not working anymore in installed arch

Thank you, Scimmia.
But I just don't get how this worked (Or more likely why that even happened, cause as I had written before I had those problems I was able to use internet and xfce4 for a few times).

This only happens when the kernel updates. Each kernel has its own set of modules, these get replaced with the modules of the newer kernel when it updates. You can't use the new kernel's modules with the old kernel. The Arch packages will, by default, install the new kernel into the /boot node. If you do have that mounted during that time, you will have the new kernel's modules, and install the new kernel into your  ESP partition or if it wasn't mounted into your /boot directory with the new kernel on your root partition. If you now reboot, GRUB will start see the kernel on your  root partition and boot that kernel, this will work fine for the modules that the kernel has built in, but the wifi and graphics card modules will be loaded after the kernel has booted, however you are still on the old kernel and it can't find it's modules since they were replaced earlier, hence no wifi and no xorg.

If this is SOLVED for you, don't forget to edit your initial post's title.

Edit: By virtue of what I just told you and Scimmia points out, either make sure that your ESP is mounted to /boot and adjust your GRUB config so that it loads the kernel from the ESP, or do not mount your ESP to /boot since currently GRUB is configured to look at the / partition.

Re: [Solved] Internet and startx not working anymore in installed arch

I see.
Mounted all partitions as before at my live cd, because EFISTUB is in my fstab, then redid grub-mkconfig -o /boot/grub/grub.cfg, then pacman -Syy and - just in case - pacman -S linux.
Both uname -r and pacman -Q linux shows 4.12.10-1 now. Also startx and - at least - ethernet connection seems to work permanent now.

Thanks, V1del.

Edit: Can connect to wireless internet again after removing NetworkManager. Now I am only using wpa_supplicant with one script to manually connect written by myself.
