Unhandled exception: HardwareDisplayDriver.cs:line 163

[martin1ehm]

Hi

I tried to run the sandbox on my rm2 device. Unfortunately I always get the following error.

Does the library work already on the rm2?
...or am I just missing something here.

I am using the latest commit 713bf39

reMarkable: ~/ dotnet/dotnet ./rm_sandbox/Sandbox.dll

Thanks in advance 😊

It dies trying to trigger a refresh, i'm going to have a go fixing this

[Eeems]

@martin1ehm are you running it in context of rm2fb?

[i-am-shodan]

I can't speak for @martin1ehm but i'm running it with:
LD_PRELOAD=/opt/lib/librm2fb_client.so.1.0.1 ~/dotnet/dotnet Sandbox.dll

I've had to made other changes like fix input device handling with:
Touchscreen = new HardwareTouchscreenDriver(deviceMap["pt_mt"], 767, 1023, 32);

[Eeems]

It might be that rm2fb doesn't handle the managed .NET code properly. I would recommend opening an issue on rm2fb and getting some help sorting out support there.

Hey guys, I guess the first issue escaped my inbox, my apologies! It's possible that the device isn't named pt_mt anymore when listed via /proc/bus/input/devices. Unfortunately I don't have an rM2 to test this on, could someone verify this?

@martin1ehm are you running it in context of rm2fb?

No but now I do, I had probably misunderstood how the whole thing works. 😅
To be honest I am more of a C# programmer and less familiar with Linux systems...

After starting from scratch i also tried LD_PRELOAD=/opt/lib/librm2fb_client.so.1.0.1 ~/dotnet/dotnet Sandbox.dll
Now I get the following message.

reMarkable: ~/ LD_PRELOAD=/home/root/librm2fb_server.so.1.0.1 ~/dotnet/dotnet Sandbox.dll

Which "signature" is meant here?

You are running the server.so instead of the client.so.

If you installed from toltec, you can run it with the following for simplicity: rm2fb-client ~/dotnet/dotnet Sandbox.dll. You will need to make sure that the rm2fb server is running though.

[martin1ehm]

@Eeems OK, looks like I must have missed the server/client thing

While starting the server (without Toltec) with the command LD_PRELOAD=/home/root/librm2fb_server.so.1.0.1 /usr/bin/xochitl I get the following messages.

With the server running I tried to start the sandbox (this time with the client) and got the original error message again.
