HDMI works, but I only get a black screen

VisionFive 2 （English Forum)

I’ve installed Image-69 and can login through SSH or the serial command, but I get a black screen on the HDMI display without mouse cursor.

It looks like HDMI is working, but lightdm is crashing:

I’ve tried two displays, none of which are 4K, One is Full HD and the other is 1280x800.
I’ve checked the thread: How do I set up a GUI on Debian? too.

Here’s the full log: PrivateBin

The U-boot part does not show up because it’s cleared during boot in my terminal program.
I have recorded it with the sdcard.img file too:

I can not share the link for that one, since I’m only allowed to add one link.

I’m able to force the second display to 1920x1080 on other systems, so I’ve set:

display-setup-script=xrandr -s 1920x1080

But lightdm still crashes. Same with 1280x720.

@cnxsoft - did you install the newer u-boot and low level firmware? at least v2.6.0 is required for newer kernels like used in the 69 image … if you already have the newer firmware, maybe you can give my experimental debian sid image a try from: imagebuilder/systems/starfive_visionfive2 at main · hexdump0815/imagebuilder · GitHub … it has a patch in the kernel to give a boot console and xorg is using the framebuffer

good luck and best wishes - hexdump

As of 3 weeks ago, we have v2.8.0 firmware release. I only installed it yesterday LOL. Please give it a try. I also use the debian experimental sid image. apt-get update/upgrade work well on it. Network and chroot /mnt for nvme work well on it.

I’m still on console ssh. I haven’t played with the desktop gui yet.

ONE HUGE NOTE: please use a higher wattage power supply 5W/10W doesn’t cut it. 20W is sufficient which is what I have, but I heard others are using 60W. If you risk using a lower wattage power supply, you’re going to see weird errors from storage devices.

Yes, I have installed v2.8.0. When I had not done this, I was not able to reach the login prompt in Linux (in the serial console)

I started with a 5V/2A power supply, the board was stuck in a boot loop… I’m now with a 100W power supply. That should be OK :smile:

If I had a blank screen I’d hop on this thread
