I’ve used Manjaro more than a year. My laptop has a dedicated nVidia GPU along with integrated Intel HD GPU. I used optimus-switch for GPU management. But today I learnt about PRIME for GPU management. So I installed hybrid-intel-nvidia-prime driver from manjaro settings. and as prime-run was not working by default, so I added this fix also.
In my case /etc/X11/xorg.conf.d/10-prime.conf is:

Section "ServerLayout"
    Identifier "layout"
    Screen 0 "iGPU"
    Option "AllowNVIDIAGPUScreens"
EndSection

Section "Device"
    Identifier "iGPU"
    Driver "modesetting"
    BusID "PCI:0:2:0"
EndSection

Section "Screen"
    Identifier "iGPU"
    Device "iGPU"
EndSection

Section "Device"
    Identifier "dGPU"
    Driver "nvidia"
    BusID "PCI:4:0:0"
EndSection

[I have no knowledge what this script do :sob:]

now prime-run is working fine but when I suspend my device and wake it up again after a period, rather than getting back logging screen, a blank screen is showing. After such a longer period(may be 2-3 min) the logging screen comes. But with optimus-switch I had no such issue…

Here is my system specification:

:+1: Welcome to Manjaro! :+1:

  1. The 450 series is known to have a few bugs, so try the 440 series first especially with a 930M

  2. If that wouldn’t help, please read this:

    How to provide good information in your posts - Tutorials - Manjaro Linux Forum

    and post some more information so we can see what’s really going on. Now we know the symptom of the disease, but we need some more probing to know where the origin lies…

    An inxi --admin --verbosity=7 --filter --no-host would be the minimum required information… (Personally Identifiable Information like serial numbers and MAC addresses will be filtered out by the above command)

:innocent:

I don’t know if it’s just in this post, but it should be “PCI:1:0:0”.

Does it happen after reboot? What happens if you switch to a TTY and switch back when this happens?

4

That’s why I asked OP to provide the inxi output: it could be PCI:4but that depends on his/her hardware…

:grin:

User reported this happened only once and then got fixed. Closing this topic.
