Working with an acer aspire 6930. Running LINUX MINT 21.3. External monitor will not work when plugged into HDM or D-Sub ports. Laptop monitor is disabled, and external monitor reports no signal.

[Edited the thread to add model number to the title]

    HDM port used to work under Windows Vista. Not so much under LINUX. When I plug the HDMI cable in (known to be good when used with my Windows 10 machine), LINUX does not see the external monitor, so I am unable to extend or duplicate my acer monitor. (I was able to do this easily on my Windows 10 machine). LINUX reports that all my drivers are up-to-date.

    Did you try to install the display driver?

    There were no drivers supplied, but I guess it wouldn't hurt to go to the vendor's website and see if any are available. When I hooked it up to my Windows machine, it just worked. I'm finding this LINUX thing is a different animal, indeed.

    Check on the linux if they have this driver 4500MHD.

    I will look into this driver. What is it for? Thanks.

    It is for the graphics driver.

    I have an Aspire 6930 that was pretty much useless as a VISTA machine. So, I got the bright idea to load LINUX MINT. I'm up to version 21.3. The machine is happy enough running this version, but I am unable to get a two-monitor setup to work past the login screen. Surely I can't be the only pioneer that's gone off in this direction. Has anyone else seen this? If so, have you resolved it? If so… HOW???

    The LINUX forums say the kernel configures video and that there are no drivers to load.

    1. Try Fn + F5 (monitor toggle key)
    2. In terminal:
    xrandr --auto
    
    1. Check hardware detection:
    xrandr -q
    
    1. Check graphics card:
    lspci | grep -i vga
    
    1. Update graphics drivers based on results

    Need more details on any step?
