• Computer won't reconnect to monitor after sleep or monitor shut off


    I’m having a similar problem to this post which received no replies.

    Whenever my computer loses connection to my monitor (goes to sleep, monitor turned off, etc) even for a second, it cannot reconnect and the monitor receives no image until I restart. When I force a restart everything is fine again.

    Any idea what I should look at or what I should google? I can’t come up with a search term that returns anything related to my problem.

    I’m running a Intel Core i7-4770K w/ a GTX1070 graphics card and Antergos is up to date.

  • needs more information about DE + Driver in use

  • Thanks for replying.

    I’m running Gnome.

    I’m having this issue with both the standard driver and the Nvidia driver. I’m currently running the Nvidia 390.48-13 driver.

  • The problem is popping up for long term on different drivber versions with Display Port connected Displays.

    • Is this the case at your system?

    • how do you install nvidia drivers?

    If you want that i do some deeper search to help you i need as much information as you can give here…

    lspci > log.txt  && journalctl -b -0 >> log.txt && cat /var/log/Xorg.0.log >> log.txt && cat log.txt | curl -F [email protected] https://ptpb.pw/?u=1
    

    this will copy relevant logs and specs to a file and upload it to a pastebin service, and then gives an url to it you can post here.

    I am using the DVI output to HDMI on my monitor.

    I downloaded the driver from Nvidia and ran the installer. It added the repository and has been updating on its own since then.

    If it matters, both the Nvidia driver and standard driver correctly identified my monitor, a Seiki SE39UY04.

    this is not the recommended way to install nvidia driver…

    i would recommend to uninstall the nvidia driver and use nvidia-installer from our repositories to install the driver properly.

  • You know what, I’m an idiot. I did install it the way you said and just forgot. It all came back to me as soon as I saw that page. I checked the pamac history to be certain. Here’s everything that seems relevant.

  • @joekamprad said in Computer won't reconnect to monitor after sleep or monitor shut off:

    entry_SYSCALL_64_after_hwframe

    i can see that the trace is also not relevant at all, as it is comming up with last nvidia update to all installations…

    As you say that you are using adapter to attach the display, it is may by a good idea to try disable dksm power off for it, try manual with:
    xset s off -dpms (Disable DPMS and prevent screen from blanking) before suspending
    or put:

    sudo nano /etc/X11/xorg.conf.d/10-monitor.conf
    with :

    Section "Monitor"
        Identifier "SE39UY04"
        Option "DPMS" "false"
    EndSection
    
    Section "ServerLayout"
        Identifier "ServerLayout0"
        Option "StandbyTime" "0"
        Option "SuspendTime" "0"
        Option "OffTime"     "0"
        Option "BlankTime"   "0"
    EndSection
    

    to make this permanent.

  • I tried:

    xset s off -dpms
    

    and that didn’t change anything.

    To clarify, I tested by leaving my computer on (as it had been for the past few hours) and turning my monitor off and back on. When I turned my monitor back on, it received no signal.

  • @joekamprad

    I don’t know what the root cause was, but I reinstalled and it now works fine. I have not tried the Nvidia drivers and am currently using the standard ones.
