I tried to look up info about Android using on multiple displays but all I ended up were split screen topics, so no info on that
My Note8 runs Android Pie and it can work with both phone’s touch screen and HDMI (DeX mode). Interestingly enough the original DeX dock supported only one display or display mirroring, but with Pie and new USB-C to HDMI adapter now both works.
So I would guess it has to be some hardware feature that is able to talk to Android’s driver.
Hi, Spikerguy
Our team are developing the dual display function for VIM3. But it still has some issues.
About the touch screen on Ubuntu, you can refer to this.
We will release the dual display support on android for VIM3 in early November
I just want to start testing only touchscreen display with vim3 and i have tried both as per that thread.
Ubuntu doesn’t display anything while Android only displays the khadas logo which is stretched as shown in that video.
Others have reported that it works but not working for me. What can be the issue?
The Link you recommended above is for egde and not vim3.
Hello Dear,
Thank you for the Links.
I have gone through the Touchscreen Link and it looks like I can add it to the kernel and the dts.
But the LCD one is little complicated for me to understand with my limit knowledge of kernel development. The reason is there is a separate amlogic directory maintained in your BSP which differs from the mainline directories.
I am not sure about the following files and the changed you have done to them. As these files are not present in the mainline and also no such directory is there.
aml_bl.h
aml_bl.c
lcd_vout.h
lcd_vout.c
lcd_common.h
lcd_common.c
If someone can advice me on how to add these to the mainline kernel then I can try it myself. I have forked @balbes150 git branch as we have mostly everything working on that built.
