• Boot into a black screen after update


    Hi,
    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,

    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:

    1. 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 vboxvideo doesn’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.

    2. 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-session as last command in xinitrc.

    3. 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”

    1. I tried (as recommended in https://bbs.archlinux.org/viewtopic.php?id=7329)
    startx /usr/bin/gnome-session 
    

    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
    
    1. Downgrade to webkit2gtk-2.12.5.1 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.

    1. 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.

    There are lots of places where you can post your log files. For example, pastebin.com.

  • If this is the same bug that has effected all of us, another update has been released fixing this.

  • @izznogooood well, the latest pacman -Syyuu command 5 minutes ago didn’t solve the problem, unfortunately.

  • @joekamprad thank you for this hint, I will send the logs tomorrow

  • ok, here are my log files:

    journalctl -b -0 -> Journal

    Interesting for me is the gnome-session part

    gnome-session[802]: X Error of failed request:  BadValue (integer parameter out of range for operation)
    gnome-session[802]:   Major opcode of failed request:  154 (GLX)
    gnome-session[802]:   Minor opcode of failed request:  3 (X_GLXCreateContext)
    gnome-session[802]:   Value in failed request:  0x0
    gnome-session[802]:   Serial number of failed request:  19
    gnome-session[802]:   Current serial number in output stream:  20
    gnome-session[802]: gnome-session-check-accelerated: GL Helper exited with code 256
    gnome-session[802]: modprobe: FATAL: Module nvidia not found in directory /lib/modules/4.13.9-1-ARCH
    gnome-session-c[3946]: eglGetDisplay() failed
    gnome-session[802]: gnome-session-check-accelerated: GLES Helper exited with code 256
    

    I’m wondering, if there is any hint why the session does not survive and why it is fatal that the nvidia module is not found. I run Antergos in a virtualbox, which does not simulate nivida graphics as far as I know.

    Xorg.0.log
    lightdm.log
    x-0.log

    Is there any other log which might be helpful?

  • I couldn’t solve this problem, but I was able to get a login screen. This didn’t let me start gnome either. So I installed xfce, which works fine since then. Perhaps one day I’ll get gnome running again. Meanwhile I spent a lot of time to get my antergos running with a GUI, so I won’t go for this problem for quiet a while.

  • Question is why something is invoke modprobe nvidia, may VM is using somehow using nvidia graphics directly, this is possible with the pass-through.

  • Thank you for the reply. I’m not aware that the VM is using the nvidia graphics directly. I don’t know how to check if pass-through is used or not. Since it worked before the antergos update and the virtualbox hasn’t changed since then, it should have to do with some settings for gnome. Do you have any further hint?
