This is my first post here. I’m a Linux user for some years, but not too much into the depth of the OS. I’m using Antergos now for nearly a year as guest in virtualbox and I really love it. Some time ago I did the last update and since then I only get a black screen after boot.
I tried really a lot of things mentioned here in the forum, but couldn’t solve the problem on my own. Therefore I ask for help here.
I can switch to tty by Ctrl+Alt+F*. With Ctrl+Alt+F1 I get the following screen:
starting version 235 AntergosRoot: recovering journal AntergosRoot: Clearing orphaned inode 1831449 (uid=1000, gid=100, mode=0100644, size=17790) AntergosRoot: clean, 548237/2354688 files, 5063613/9406720 blocks [FAILED] Failed to start Avahi mDNS/DNS-SD Stack.

I did not find anything helpful for me in the journal, Xorg.0.log, lightdm.log, x-0.log, but some of you knowledgeable people hopefully see more.
I can’t post the log files here, because the post would be too long and I haven’t the previleg to upload files. I’d happy to send them, if I knew how.
To mention, what I already did:
I found an error in Xorg.0.log concerning the vboxvideo module.
(EE) Failed to load module "vboxvideo" (module does not exist, 0). But the module exist and
modprobe -a vboxvideodoesn’t give an error-message. I also found that this ‘missing module’ is not responsible for the black screen since I found the same error message in Xorg.0.log when I start a live iso of Antergos in the same virtual machine, which works perfectly.
I tried to start the X server from command line but it seems to start and terminate immediately after start. The log file also shows, that it terminates successfully. Just to see what happens I installed xterm and twm which are called by the xinit script. With both installed the X server doesn’t terminate and I get twm with xterm. But still I can’t open a gnome-session even when I put
exec gnome-sessionas last command in xinitrc.
I changed from lightdm to gdm as mentioned in lightdm not loading and rebooted.
Result after reboot: black screen. In journalctl I found: “gnome-shell Failed to create backend: Unable to open display, Display not”
- I tried (as recommended in https://bbs.archlinux.org/viewtopic.php?id=7329)
Result after reboot: Black screen, X server terminated successfully, but in /var/log/Xorg.1.log I got the following errors:
# grep '(EE)' /var/log/Xorg.1.log (WW) warning, (EE) error, (NI) not inplemented, (??) unknoun. 642.524] (EE) Failed to load module "vboxvideo" (module does not exist, 0) 642.610] (EE) modeset(0): eglGetDisplay() failed 642.611] (EE) modeset(0): glamor initialization failed 642.615] (EE) AIGLX: reverting to Software rendering
- Downgrade to webkit2gtk-184.108.40.206 as mentioned in https://forum.antergos.com/topic/5180/login-issue-with-lightdm-webkit-greeter-not-accepting-user-input/2
Result after reboot: Black screen. In journalctl there was an entry ‘lightdm no password for autlogin’, which I was wondering about.
- Because of the ‘lightdm no password for autlogin’ I thought there might be an issue with permissions and applied the recommendation of https://forum.antergos.com/topic/6872/black-screen-and-mouse-pointer-after-login/8 which didn’t change anything.
Since I tried now for more than a day to fix this problem, I hope some of you can help or point me in the right direction.
