Blank screen after updating system

opensas

I have antergos up and running, and after a system update with “pacman -Syu” I get a blank screen on booting.

I can’t event switch to console using ctrl-alt-fx

I have a dell Inspiron 11

Here’s some info that might help (I’m running it from an ubuntu 18.04.1 on a different partition)

$ lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation Haswell-ULT Integrated Graphics Controller (rev 09)

$ lsmod | grep “kms|drm”
drm_kms_helper 172032 1 i915
syscopyarea 16384 1 drm_kms_helper
sysfillrect 16384 1 drm_kms_helper
sysimgblt 16384 1 drm_kms_helper
fb_sys_fops 16384 1 drm_kms_helper
drm 401408 15 drm_kms_helper,i915

I can access my antergos partition, but I don’t know which logs sould I have a look at.

On another partiion I installed manjaro and I have the same trouble.

Some more info that might be useful:

@opensas
You can boot with the Antergos installer USB stick, and chroot to the installed Antergos.
So after boot, start a terminal.

Below you’ll need values for X, Y, and Z, you can see them with e.g.

lsblk -fm

Now chroot to Antergos:

su
mount /dev/sdXY /mnt       # Antergos root partition
mount /dev/sdXZ /mnt/boot  # Antergos boot partition, if you have it
arch-chroot /mnt

Now you are in the installed Antergos.

Some ideas you could try to fix or work around the problem:

You might want to try a different kernel:

pacman -S linux-lts linux-lts-headers

Change Display Manager (lightdm, sddm, gdm)

pacman -S sddm             # new DM
systemctl disable lightdm  # current DM
systemctl enable sddm      # new DM

Update again, now refreshing the repos:

pacman -Syyu

and reboot to the installed Antergos.
If any of these doesn’t work, repeat and try another.

@manuel I’d like to try some of those step, but the problem I have is that antergos live cd won’t recognize my wifi card. Once installed, it does recognizes it, but it won’t pick it from the live cd.

I can boot to a manjaro or ubuntu partition, but I can’t run arch-chroot from there

Is there some way to manually mount the antergos partition, or download arch-chroot to use from other distros?

–

I’ve just installed it with $ sudo pacman -S arch-install-scripts… wish me luck

opensas

it seems the problem is the display manager

I disabled lightdm and enabled gdm and now it works

I tried reinstalling lightdm but still get the same problem

also tried to uninstall it but I get:

$ pacman -Rns lightdm
[sudo] password for sas: 
checking dependencies...
error: failed to prepare transaction (could not satisfy dependencies)
:: antergos-common-meta: removing lightdm breaks dependency 'lightdm'
:: gnome-shell-extension-status-menu-buttons: removing lightdm breaks dependency 'lightdm'
:: light-locker: removing lightdm breaks dependency 'lightdm'
:: lightdm-webkit2-greeter: removing lightdm breaks dependency 'lightdm'

Any other idea how could I troubleshhot lightdm?

Reinstalling do not help in most cases.
Troubleshoot needs logs

You can try:

journalctl | grep lightdm
