Can't get HDMI Out on Debian image (modetest either)

VisionFive 2 （English Forum)

I’m running the latest Debian image (69), and have already updated uboot/firmware. I get no output over HDMI at all (it doesn’t even flash my display or anything).

Modetest output:

And trying a test pattern looks like it should do something but nothing happens on my display (I have triple-checked it is set to the right input, and also used the same HDMI cable with a Raspberry Pi 4 and Orange Pi 5 to verify they are able to get a signal):

user@starfive:~$ sudo systemctl stop lightdm
user@starfive:~$ sudo modetest -M starfive -s 116:1920x1080-60Hz
sudo: unable to resolve host starfive: Name or service not known
setting mode 1920x1080-60.00Hz on connectors 116, crtc 31

Here’s also all the dmesg output related to HDMI:

Mr. Geerling,

Try using an older hdmi 1080p only monitor. I’ve gotten success on two older hdmi only monitors.

Your output mentioned another small error:

sudo: unable to resolve host starfive: Name or service not known

Your sbc still has a hostname set to starfive. Please change that with hostnamectl:

hostnamectl set-hostname geerling-image-69-vf2

Then place geerling-image-69-vf2 in your /etc/hosts:

127.0.1.1 geerling-image-69-vf2.localdomain geerling-image-69-vf2

I have learned something again. Since I replaced the home NetWare server with S.u.S.E. Linux in 1996, I have set the hostnames via DHCP/named and have never had any problems. Of course, new systems initially have a wrong name in the prompt and I have to change /etc/hostname, but both Visionfive 2 gave me an error message for the first time because of this.

mike@ddc:~$ sudo joe /etc/dhcp/dhcpd.conf

host    vfive2-8 {
  hardware ethernet 6C:CF:39:00:21:E5;
# hardware ethernet 6C:CF:39:00:21:E5; eth0 - 1000 mbit
# hardware ethernet 6C:CF:39:00:21:E6; eth1 - 100 mbit
  fixed-address 192.168.178.143;
  option host-name "vfive2-8";
}

host    vfive2-4 {
  hardware ethernet 6C:CF:39:00:2E:D7;
# hardware ethernet 6C:CF:39:00:2E:D7; eth0 - 1000 mbit

  fixed-address 192.168.178.144;

I’ll try with a couple other monitors (the one I’m testing is a pretty old HP, but I’m using HDMI to DVI for it).

I also should note that following the How to use external gpu on VisionFive v2 - #24 by geerlingguy thread, I’m actually able to get output through the same monitor from an AMD Radeon graphics card—though I can’t get a display manager to run (something with the PVR driver I guess, conflicting with radeon).

FYI I had to try a few different HDMI cables until I found one that worked. For some reason it didn’t like some that worked fine on other devices. I didn’t investigate why - cable length maybe

No matter what I couldn’t get it working with my HP monitor, but I can get output through to an Atomos Ninja V. A bit annoying since that screen is so tiny :smiley:

I’ll test out other monitors in due time.
