Hi! I am running [balena-pihole](https://github.com/klutchell/balena-pihole) project which includes PADD on my raspberry pi 3 using balena cloud and following [these instructions](https://www.balena.io/blog/deploy-network-wide-ad-blocking-with-pi-hole-and-a-raspberry-pi/). The pihole+dnscrypt-proxy work as expected except of PADD which is supposed to automatically run when it detects the pitft display. For PADD setup following [these instructions](https://www.balena.io/blog/add-a-display-to-your-pi-hole-for-monitoring-and-stats/) but using [adafruit 2.8" capacitive pitft display](https://www.adafruit.com/product/1983) instead of Adafruit 3.5" resistive pitft display. Here are the instructions for enabling driver of the mentioned pitft 2.8" display (just from another project): [https://github.com/balena-io-projects/balena-wpe#capacitive-touchscreen](https://github.com/balena-io-projects/balena-wpe#capacitive-touchscreen). The configuration of both these displays, as we can see actually, looks almost the same. The display seems to work well after adding the following balena vars: ```auto RESIN_HOST_CONFIG_gpu_mem = 64 RESIN_HOST_CONFIG_dtoverlay = pitft28-capacitive,rotate=270,speed=25000000,fps=20 RESIN_HOST_CONFIG_hdmi_cvt = 320 240 60 1 0 0 0 RESIN_HOST_CONFIG_hdmi_force_hotplug = 1 RESIN_HOST_CONFIG_hdmi_group = 4 RESIN_HOST_CONFIG_hdmi_mode = 87 ``` I expect PADD to appear on the pitft display automatically after adding the configuration variables in BalenaCloud app and rebooting the pi. Am I wrong? Do I need to do any additional configurations which are not mentioned in the PADD setup instructions? What actually happens: after booting pi the screen is white with the Balena Logo, then after I see in pihole application logs `Starting PADD` the screen turns black, but no text is visible. Please help to make PADD work with the mentioned display. Thank you. ---

Hey @drew, Welcome to the forums! From the settings you provided, it looks like you set `RESIN_HOST_CONFIG_hdmi_group=4` while it should be set to `2`. Can you try setting `RESIN_HOST_CONFIG_hdmi_group=2` and see if PADD appears on the TFT display? Let us know if it works for you. Cheers, Rahul ---

Thank you @rahul-thakoor for reply! I have tried that and it did not work. Once I changed the value of `RESIN_HOST_CONFIG_hdmi_group` from 4 to 2, the screen is still just black. Seems like it changed nothing. But thank you anyway for trying to help! Any other suggestions? ---

Hello, I don’t have this screen so I’m just guessing The project you mentioned uses `RESIN_HOST_CONFIG_dtoverlay=pitft28-capacitive,rotate=90,speed=62000000,fps=60`, not `RESIN_HOST_CONFIG_dtoverlay=pitft28-capacitive,rotate=270,speed=25000000,fps=20` ---

Hey there @drew After a bit of digging we’ve found this to be an issue introduced sometime after balenaOS 2.38; if you flash your device with that version it should work OK. I’ve created an issue to track this: [https://github.com/balena-os/meta-balena/issues/1772](https://github.com/balena-os/meta-balena/issues/1772) ---

Just curious, is this planned to be fixed in the next balenaOS release or later? Thank you! ---

Hello, There’s about a 2-3 week release cycle for balenaOS, and since this is a new issue it won’t likely make it into the next release. It’s on the radar now though, and I would think it might be addressed in a month or so. I’d recommend checking back in about that time, though feel free to ask for an update of course! ---

Hi there! I am an OP and just decided to update to current 2.47.01rev (supervisor: [10.6.27](https://github.com/balena-io/balena-supervisor/blob/master/CHANGELOG.md#v10627)) and my PADD stopped working - after reboot just white screen. Could anyone confirm that current issue with pitft displays was fixed, or should I revert back to 2.38? Thank you. ---

Hello @drew, the issue ([https://github.com/balena-os/meta-balena/issues/1772](https://github.com/balena-os/meta-balena/issues/1772)) still appears to be open, so I would revert back to version 2.38 for the time being. I’ll see about getting an updated estimate added to the issue as well. ---

Hi @alanb128. Weird enough, but after I reverted to 2.38, I see the same issue, as the one I have described above - white screen, no balena logo, no PADD… In fact, in logs I see the following: ```auto 14.04.20 12:17:28 (+0300) pihole /dev/fb1 not found. Disabling fbcp & PADD ``` So it seems like it does not detect pitft or something and pihole automatically disables PADD… Now I am confused. Please help me to get my piftf display work with balena again. UPDATE: Another strange thing I have noticed is that I can not ssh to my host os using UI: ![Screen Shot 2020-04-14 at 12.28.25 PM](https://global.discourse-cdn.com/balena/original/2X/5/5b72a0039900d55a0b2dd9917ea4917f21acb710.png) Although I am able to do it with ```auto balena ssh 192.168.2.2 root@6e832ec:~# ``` Something weird happens(( ---

Ok, sorry, I got it… That’s just me, being idiot. I forgot to set `RESIN_HOST_CONFIG_gpu_mem` config variable… Still exploring. ---

hey @drew if you grant support access (see the actions menu of the device) for your device and send me your device UUID in a private message I can have a quick look to see why perhaps the webterminal doesn’t work. ---

Hi @shaunmulligan! I apologize for such a late response - I simply missed the message. No worries, it’s already working… I guess after some update. Still thank you very much for your help attempt!
