    Default KDE aks for monitor switching on a desktop PC

    New HP Pavilion Desktop TP01-2050nl.

    The monitor is connected through the HDMI cable.

    Every now and then KDE pops-up rather huge rectangle in the middle of the screen. It shows four images each one with two monitors, either close to each other, or separated or different, red arrows and texts like "Switch to laptop", "Switch to external", ...., and the most right image is a huge circle with a dash. Clicking the last removes the rectangle. The rectangle removes itself after about 10-20 secs.

    What is the idea. Special because one or more of the images talks about "laptop". And of course, how to get rid of it for good. And maybe file a bug with KDE when I understand more of this phenomenon.

    Question Re: KDE aks for monitor switching on a desktop PC

    @hcvv:

    Henk, which GPU Driver are you using?
    • The box has an AMD Ryzen™ 5 3400G CPU with integrated GPU.

    You should be using the “amdgpu” driver.
    Code:
     > lsmod | grep -i 'amd'
    edac_mce_amd           32768  0
    kvm_amd               110592  0
    ccp                   102400  1 kvm_amd
    kvm                   786432  1 kvm_amd
    gpio_amdpt             20480  0
    gpio_generic           20480  1 gpio_amdpt
    amdgpu               6381568  62
    iommu_v2               24576  1 amdgpu
    gpu_sched              45056  1 amdgpu
    i2c_algo_bit           16384  1 amdgpu
    ttm                   118784  1 amdgpu
    drm_kms_helper        262144  1 amdgpu
    drm                   618496  26 gpu_sched,drm_kms_helper,amdgpu,ttm

    Is this correct or not?

    BTW, I just installed a fresh 15.3 and did not specify anything about GPU drivers.

    Henk, you need the “amdgpu” driver –
    Code:
     # modprobe amdgpu

    Looks rather different from what it was. We (it is the system my wife uses most) will now watch if the blob returns or not.

    Not a clever action. Now the situation is as before the modprobe.

    Something to make that stick over boot?

    should work:

    create the config file:

    /etc/modules-load.d/amdgpu.conf


    open it and add the module name:
    amdgpu

    amdgpu
    beneden:/etc/modules-load.d #
    Reboot.
