Enabling an on board device from within a Linux system

Question

I'm currently using an Acer Predator G3-605 desktop of which I need to access the integrated graphics because my GPU doesn't have a VGA or HDMI connector and I just so happen to find myself with only wires with those connectors. However, the on board devices which host the VGA and HDMI connectors is disabled for some reason. See the following outputs:

$ sudo dmidecode -t 10
# dmidecode 3.6
Getting SMBIOS data from sysfs.
SMBIOS 2.7 present.

Handle 0x0019, DMI type 10, 12 bytes
On Board Device 1 Information
    Type: Video
    Status: Disabled
    Description: Intel(R) HD Graphics
...

$ sudo dmidecode -t 41
# dmidecode 3.6
Getting SMBIOS data from sysfs.
SMBIOS 2.7 present.

    Reference Designation:  Onboard IGD
    Type: Video
    Status: Disabled
    Type Instance: 1
    Bus Address: 0000:00:02.0

Now the Acer Predator G3-605's BIOS (P11.B3) is -- to put it gently -- incredibly limited. So I can't re-enable the on board devices via BIOS. Is there any way to enable them from within a linux system?

Answer 1

I don't know if it's possible to activate it through your OS.

If not, I would first remove the GPU and see if that's why the onboard graphics are deactivated.

On some motherboards, the integrated graphics are automatically activated on the next startup as soon as the dedicated graphics card is physically removed.

If that doesn't work, I would reset the BIOS to load the factory settings.

And if resetting to the factory settings over the BIOS doesn't work, I would disconnect the power cable and remove the CMOS battery on the motherboard if possible.

Leave the battery out for 5-10 minutes, put it back in, and see if the BIOS has loaded the factory settings.

Then check if the onboard graphics card works.

To reset the BIOS to default settings on your Acer Predator G3-605 desktop, enter the BIOS by pressing the Delete key when the Acer logo appears on startup, then press F9 to load the default configuration and F10 to save and exit. If this method doesn't work, you can perform a hardware reset by unplugging the computer, opening the case, removing the CR2025 CMOS battery for a few minutes, then reinserting it
