    Linux Mint v20.0 displays a blank screen if I don t have monitor turned on before I boot up computer. The Dell logo appears, then blank screen. (I use a 60" tv as a monitor). I can still enter decryption password, and then the normal login screen appears. If I have tv on before I boot up it works as it should. Has anyone ran into this? I m not sure if this is a problem with my configuration, or just a bug/limitation of Mint.

    What gpu are you on? If it is an nvidia, do you use the nvidia driver or the one that every distro comes with (nouveau)?
    Also, is this the only monitor connected to the gpu?

    No Nvidia. TV is only monitor. TV is an LG OLED 4k@65". I m using a display port, (computer), to HDMI, (TV), cable.

    Subsystem: Dell HD Graphics 530
    Kernel driver in use: i915
    Kernel modules: i915

    ~$glxinfo | grep -i "vendor\|rendering"

    Maybe the framebuffer (= the "screen" with the logo before the login prompt appears) is not capable of 4k or it gets the tv's refresh rate out of range.
    If you connect it on a regular monitor, do you see the prompt to enter the decryption password?

    My comp is a Dell 7040 Optiplex and the display ports are only capable of 1080p output, so I can t get 4k through the computer. I m not sure what resolution it is at the decryption password screen. I have an vga monitor but no cable, so I can t try that atm. I checked LG website for specs for tv;

    PICTURE(PROCESSING)
      • Picture Processor

    The comp is five/six years old, and tv is less than a year old. I guess I should be gratefull that they work together at all, but the gaming mode part of the tv specs got me wondering, because refresh rate is different. In gaming mode the refresh rate is variable. I will try to leave in it in gaming mode, and see if that changes anything

    Installed LinuxMInt Ulyana 20 XFCE today on very old system with 2+2=4gb SoDimm RAM & 320gb HDD P4 3.0 Processor on G41 Motherboard.
    Everything Working Fine Here without any issue. PCI USB3 Card Speed is also resolved in LinuxMint 20.

    Like you mentioned; I believe it was the refresh rate that was causing problem. I changed the tv settings to game mode which changes it to a variable refresh rate, and I now get the decryption password screen. I tried it multiple times, and they all worked, so I have to give you props. Thanks a bundle!
