Problems with display / black screen after installation / upgrade (Kernel 5.4)

[sr1329]

Describe the bug
Installed manually Octodash 2.0.0 ARM64 version onto Octopi 18.1 64bit. Followed all directions including autologin into the text interface. Usually an HDMI attached display would show a bunch of scrolling text and then a prompt. Now it shows two weird distorted diagonal lines of text. It resembles how a VCR head writes data diagonally on a rectangular piece of magnetic tape. Then instead of a prompt it just says "no signal".

I went to troubleshooting and got while attempting a manual start:

pi@octopi:~ $ octodash
The futex facility returned an unexpected error code.
Aborted
pi@octopi:~ $ export DISPLAY=:0
pi@octopi:~ $ ratpoison
ratpoison: There can be only ONE.
pi@octopi:~ $ octodash

To Reproduce

So I decided to try again on Octopi 17. No diagnosable weirdness however it too won’t launch into Octodash and gives errors. However it was updated to Kernel 5.4 and I believe that is what is breaking everything. I will go back and reinstall Octopi 17 and neglect to run apt-get upgrade and try again. This is on my test raspberry pi 4B 4GB.

[sr1329]

So I have tested on a new install with octopi 17. Apart from some issues reaching some mirrors to download packages (where it tells you to apt-get update - never change that to upgrade).

So it works now and I think the issue is with the new kernel. It has fully installed on the 32 bit updated kernel but doesn’t load. Ratpoison simply cannot open display.

As for Octopi 18 64bit that is still very weird and I’m not sure what happened there with the diagonal text scrolling.

Edit: Got it set up and running on another pi. Amazing program. Even got it customized to how I like it.

Been playing with it and really like it. I discovered a fix for Hyperpixel 4 for use on kernel 5.4 or even 64bit raspbian. Apparently it works if you fix the hyperpixel driver so Octodash itself is okay on 5.4 or even 64 bit. I will try that install when I get home.

Regarding HDMI output I suspect it is an issue where it says cannot open Display 0. Hopefully in time it will work on both Hyperpixel and HDMI.

@sr1329 Thank you for investigating the issue, I can confirm the bug

[UnchartedBull]

@sr1329 Could you maybe link the fixed driver for Hyperpixel here? If I understand you correctly everything is working once the correct driver has been installed?

@Tobi0892 did you manage to fix the issue as well or are you still having problems?

[Tobi0892]

@UnchartedBull I applied all proposed fixes from the wiki but hadn't yet the time to investigate @sr1329 proposition. I'll keep you updated

Actually this is on HDMI. I switched from Hyperpixel to 7” HDMI touchscreen. So no hyperpixel drivers are installed on the system.

I have a test system I intend to try the updated hyperpixel drivers on as well. For that system apparently the drivers work on kernel 5.4 but no landscape orientation is yet possible.

I am using Octodash on a 4GB 32bit pi Octopi 17; Octoprint 1.4.2. It works great. Only thing is the touch sensitive areas for the icons are hard to learn. They are very specific. For example back can only be activated when touching the “b” letter only. This might be because my screen resolution is 1024x600? Maybe the “touch here” areas could be demarcated but then again that may tank the very clean design.

Great touchscreen application and it completes my setup.

[UnchartedBull]

@sr1329 the touch boxes should normally cover the whole icon and / or text. I'll have a look at that, but the resolution shouldn't be a huge issue. Does this happen on other buttons as well or only the back button?

I might redirect a few other issue here, which all seem to have the same problem with Kernel 5.4. There also was a driver linked in this issue: #892. So sorry for all the possible message, but I want to condense this into one issue so others can easily find it.

EDIT: Here is another link: https://github.com/TxBillbr/octodash-hyperpixel-fix. Seems like the screens are working again, just not in portrait mode (which is needed for OctoDash)

[sr1329]

Yes I agree all 5.4 issues would be better consolidated. The back button is the most evident. It took me a some time to figure out where exactly to touch it. But I feel all buttons have some degree of touch not responding. In my case it seems towards the bottom I have to touch above the text and towards the top I have to touch slightly below the text. In general i tend to hunt for the touch sensitive area.

That is the size of the back button (on 1024x600). Could you maybe touch & hold the same button in the files view and check how big your light grey box is?

[sr1329]

Yes it is the size but the gray box only comes up when pressing the letter “b” On Aug 19, 2020, at 12:53 PM, Timon G. <notifications@github.com> wrote:  [Screenshot 2020-08-19 at 19 50 32]<https://urldefense.proofpoint.com/v2/url?u=https-3A__user-2Dimages.githubusercontent.com_19818061_90671721-2D5f77b680-2De255-2D11ea-2D97f1-2D9b4e8479c8b1.png&d=DwMCaQ&c=slrrB7dE8n7gBJbeO0g-IQ&r=i0iMjlNrlUgfsH63L7eELQ&m=tE9iMUab4l4_F0pCLIspN-WxjsmRTsV02k7HxVMRepE&s=TQCsO_865F4tkHvzpnwsNz6qMEr8rCEX-xMLdhCdj5c&e=> That is the size of the back button (on 1024x600).

Seems to be working better now. I think it requires a longer touch than i’m used to. I tried octoscreen for example and it accepts touches very quickly. I have set the touch refresh to 330ms.

I think it’s fine. I’m probably not used to nice delay and fade animation.
