Hi,
Is it possible to make the Cerbo GX accept a different touchscreen and get the touch functionality working. I have chosen a brand of touchscreen that should be supported by most Rpi versions out of the box, but touch still doesnt work with the Cerbo.
Any tips are welcome.
As far as I'm aware the GX Touch uses I2C data on the HDMI feed for the touch input which is non-standard. The USB is just for power.
So long story short, is no, it wouldn't be possible.
A bit late, but here is what I've done to get a 7inch Waveshare screen (1024 x 600) to work with touch.

Connect to your Cerbo via SSH.
Run the following commands...
- opkg update
- opkg install tslib-calibrate
Enable headless mode...
- touch /etc/venus/headless
Reboot your Cerbo.
Set screen resolution and run calibration utility...
- fbset -xres 1024 -yres 600
- ts_calibrate
Now go to the screen and do the actual calibration on the screen.
Once calibration is done disable headless mode...
- rm /etc/venus/headless
Reboot your Cerbo again and touch should be working.
I can't stress enough that this feature should be on the top of the list. Having a single very responsive screen SUCKS. I so badly want a screen for the front of my RV but have to settle for a browser. I still think that Victron needs to think about scaling here. I should be able to buy another Cerbo GX and Touch and use the Cerbo as a Master/Slave relationship where the Slave mirrors the Master and extends sensors, ports, etc. Scaling seems to be Victron's biggest hurdle right now. OR if scaling is a major hurdle then provide a pub/sub REST service that allows customers to build their own UI.
Just a thought: Can you control the GUI on Cerbo with a USB mouse? If so, you should be able to add the USB touchscreen stuff that's used for Venus on the Raspberry PIs.
I have the same issue. I spent over $5,000 on Victron products, but my eyes are old and can't easily see the 5" monitor. I purchased a generic touch screen (large so I can see). The image is fine, but the touch is not working. I can attach a mouse, which works, but not the touch screen part. What's the deal, where is the support? I will pay for a download patch, just please fix this problem.
Hi
Yes you can use the raspi with there 7inch touch screen just connect thew the wifi access port, I use the kiosk mode to do this, as the raspi has wifi and bluetooth. so only needs power.
So it can be remote mounted etc.
You can pinch zoom etc.

I have a 7" HDMI touchscreen that works with Cerbo. It uses USB touch like most do. It was plug and play. No tweaks.
Make sure you aren't using the USB port closest to the HDMI connector. That one is power only.
Victron also now sells the GX Touch 70, a 7" version of the same excellent 5" touchscreen. I switched to that a while back.
Hi.
I had the same issue with my new 7" touch screen 1024x600 IPS and the cerbo GX. Nothing looks normal and the touch function doesn't work.
When I turn Off the Cerbo GX, connected the HDMI to the Screen and the USB cable for the touch on the second USB port on the cerbo GX.
When I power ON the Cerbo GX, and now the touch screen works perfectly. Very simple and easy.
Hope this work for you.
I am bumping this up to see if there is any new information available? I have a 16" screen which sends touch information out via USB...will this work to view/control a Cerbo GX? I would prefer not to add another screen if I can utilize the one already installed.
I'm also going to bump up this topic.
I'm viewing the Venus GX info/display through my networked Simrad 9" MFD (model NSS EVO3S)
The Simrad resolution is a crisp 1280 x 720 but the Victron info/display (via the HTML5 app) is miniature and sits in the middle of a dark screen, while simultaneously being hard to read, since it's so small!
I wish it could scale Victron info to MAX width, or have a font increase/decrease button that made for a better and more customizable user experience.
Any leads as to how to fix this, I'm running the Venus GX off a Raspberry Pi.
I fell at the first hurdle. When I run ts_calibrate I just get an error
ts_setup: No such file or directory
Using a genuine Cerbo and generic 7" touch screen, I'd already bought it before reading this post.
It seems the Waveshare brand might just have worked out of the box.
My screen displays correctly but the touch isn't working properly, I'm guessing calibration is way out, randomly poking the screen does sometimes flip between the menu and main display but that's about it, certainly can't select things or navigate the menus.
