VIM3 with Ubuntu bionic + Touch screen TS050

Hello @Gytis

LCD driver seems broken in current source code, I will fix this…

By the way, if you want to use the LCD, you have to unplug the HDMI cable, or the LCD will not work.

Please post here when fix is available :slight_smile:

Is it so that two monitors cannot be used at the same time? From website I understood that was possible…

Current stage not, in the future, YES. Need more software support.

Any idea when that could be done?

I think I am going to use VIM3 as Ubuntu-powered home media server then with status displayed on Touch screen and VIM1 with Android plugged to TV as music and video player :smiley: Kodi on VIM3 + Ubuntu 18 looked bit sloppy - controls tend to slow down from time to time :thinking:

Please check the new image:

Tried VIM3_Ubuntu-xfce-bionic_Linux-4.9_arm64_EMMC_V20190830 - touch screen works! :grinning: But only when HDMI is not plugged.

Can you include changes to fenix build script? I’ll try to build ubuntu Bionic from source again.

Yes, it is. We will resolve this issue in future release.

Already pushed to the github. You can use the latest repo to build.

I still can’t get this working with the Edge-V, I’ve tried the new V20190830 lxde and server ROMs. Can boot initially using HDMI, edit the env.txt to “mipi_lcd_enabled=true”, sync and sudo reboot. Afterwards I still get the khadas logo on boot for the TS050 but nothing else happens and when I try with a HDMI connection it only displays a white screen.


Built Ubuntu Bionic + Xfce from source - Touch Screen works, thanks :grinning:

@blueberryberret hello.We do a test with it and we found the reason.This is a bug about dtb, which we will solve in the next release. I’ll tell you again then.


Hello @blueberryberret

I have updated the kernel to fix this issue.

Please reflash the image and update the kernel.

khadas@Khadas:~$ sudo apt-get update
khadas@Khadas:~$ sudo apt-get upgrade
khadas@Khadas:~$ sudo vim /boot/env.txt     # Edit to enable LCD
khadas@Khadas:~$ sync
khadas@Khadas:~$ sudo reboot

Just to add, Tone Board is recognized as audio device and works fine with Ubuntu Bionic Xfce :slight_smile:

I very much appreciate the quick turnaround on updating the kernel and addressing my problem:slightly_smiling_face: I can now boot ubuntu using the TS050 lcd, the only problem is that it is not recognizing touch input. Touch works when I boot android and I have tried it with the latest xfce, lxde and mate images, built using fenix as well as the ones provided on the khadas site. Touch is recognized using a hdmi capacitive screen but not with the TS050. Thanks again for the help so far!

@Gytis can you confirm that you got touch input working on the TS050 as well as just the lcd on the Vim 3. At the minute I can only get the lcd to work as a display on my edge V, touch gestures are not detected. Would almost buy the Vim 3 as well at this point, just to get it working.

You mean should I unplug touch cable and try out only with display connector?

On my VIM3 Pro I have TS050 working with Ubuntu Bionic Xfce (built from source) - screen works, touch works.

No, I was just wondering if touch was working at all, with both connectors attached. I can’t seem to get it working, just the display, no touch. Thanks for getting back to me though :+1:

I can confirm that both LCD and Touch of the TS050 work well on Ubuntu, installed on eMMC. It’s not workable though due to the size of all icons and buttons.

Thanks for the reply! Can ask if you’re using the Vim3 or the Edge V, and what firmware did you use?

Hello @blueberryberret

So you can’t use LCD on Edge-V with latest image ?

@Frank please follow up.

It’s on VIM3 with Ubuntu 4.3 eMMC. All other do not work with LCD+Touch
