Not working with Official 7" Touchscreen...

[Jaxel]

I used Etcher to install "2018-04-22_2018-04-18-fullpageos-stretch-lite-0.9.0" to my SD card. Then edited the "fullpageos-wpa-supplicant.txt" file to connect to wifi. Plugged everything in and turned it on. On first boot, it ran the bootup process on the 7" touchscreen; then went to the "resizing storage" screen and rebooted. After that, my screen is completely blank; it's just a lit up black screen.

If I plug a monitor in using the HDMI cord and boot the system, it all works fine. However, unplugging the HDMI cord and booting with the official 7" touchscreen plugged in gives me nothing.

I was able to get it working using "2017-06-24_2017-06-21-fullpageos-jessie-lite-0.7.0"; but I don't want to use that version because jessie has issues with LCD rotation and touchscreens. I have been unable to get any stretch version working with the touchscreen.

Can you try rhe no acceleration test image in nightly? http://unofficialpi.org/Distros/FullPageOS/no-acceleration/nightly/2018-07-22_2018-06-27-fullpageos-no-acceleration-stretch-lite-0.10.0.zip md5: http://unofficialpi.org/Distros/FullPageOS/no-acceleration/nightly/2018-07-22_2018-06-27-fullpageos-no-acceleration-stretch-lite-0.10.0.zip.md5

I will be streaming later today, so I won't have time to test today. Maybe tomorrow.

Are you streaming using FullPageOS?

[Jaxel]

I use it as a kiosk for my chatroom. https://imgur.com/gallery/tAuYC

I'll be streaming in about an hour or two if you want to check it out... https://twitch.tv/8wayrun

had the same problem as @Jaxel

i installed the nightly mentioned in https://github.com/guysoft/FullPageOS/issues/247#issuecomment-416015856 and it solved it for me.

[guysoft]

I guess this means gpu needs to be disabled in the touchscreen display. I will release two images next release, and we can document when to use each.

[pslogic]

Just an information note... with the built-in stand orientation of the official rpi touchscreen case, the screen output ends up being upside down. it may be worthwhile add some "heads-up" guidance to the touchscreen display distro release notes.

[guysoft]

You can write here what you think should go. And I will paste it in, or you are welcome to send a PR to the readme page.

the new "2018-11-20_2018-11-13-fullpageos-stretch-lite-0.10.0" nightly version does not work. During the first boot after flashing the SD-Card the boot sequence gets displayed on the 7" RPI screen. But after the boot sequence finishend I get a black screen. After rebooting the screen stays black even during the boot sequence...

Any Ideas?

[guysoft]

@GekoCH Try the non-acceleration version and report: http://unofficialpi.org/Distros/FullPageOS/no-acceleration/nightly/

[GekoCH]

aha hmm I did deactivate the GPU with the sudo raspi-config and now it works! Or is this wrong???

[steampixel]

Same problem here :-(

I did a sudo raspi-config Than I first switched to Advanced Options -> Memory Split and increased the GPU memory to 256 Than I launched the Advanced Options -> GL Driver panel and switched to Legacy mode Now it works A few infos about my system:

Ok, it seems quite clear that the official 7inch screen does not work if graphical acceleration enabled.

The workaround is to use the non-acceleration image.

A long term solution would be to automatically enable/disable acceleration using one of the methods listed here: https://www.raspberrypi.org/documentation/hardware/display/troubleshooting.md

However, I have no time to implement this. PRs are welcome. They should probably go somewhere in this script: https://github.com/guysoft/CustomPiOS/blob/devel/src/modules/gui/filesystem/home/pi/scripts/enable_gpu

something along the lines of

1. if touchscreen is connected, disable GPU if enabled.
2. if no screen enable gpu.

The workaround is to use the non-acceleration image.

What exactly is the non-acceleration image? nightly 2023-05-12 or nightly 2023-05-09 (from rpi Imager)?

Or do I need to build an image?

In Stable, in respi-config, if I enable Legacy mode, the last thing I see on the screen is the Network Time Sync message. It stays there, without blanking the screen, seemingly frozen.

[guysoft]

Its an image that sets:

GUI_INCLUDE_ACCELERATION=no

It changes a bunch of stuff to enable GPU acceleration on the Pi and chromium: https://github.com/guysoft/CustomPiOS/blob/devel/src/modules/gui/start_chroot_script#L19

FullPageOS currently ships in a release two images, this is the second one for these cases.

Any chance we can get the 7" touch screen to be supported? This would make for a really nice display.

Tested on all versions available on pi imager 1.8.5 Tested with several different pi's

Thanks

[guysoft]

The offical pi display worked for me a few months ago - what is not working for you?

[pauldogg]

Touchscreen input isn't working.
