Just installed. I'll let you know if I end up with any crashes or bugs. Thanks for everyone's efforts to get this working. |

the remux in toltec stable does not work on rM2 (remux will migrate to toltec stable soon). for now, it's advised to copy the remux binary from https://build.rmkit.dev/master/latest/ into /opt/bin (and make sure to EDIT: toltec testing now has a version of remux that works well with rM2 |

It installed very easily. I have tested draft, KOReader and Plato. Some very stream-of-thought notes, many may be relevant to the specific app and not this PR, apologies. Draft
Oxide
Remux
KOReader
Calculator
fingerterm
harmony
recrossable

great notes, thanks! for rmkit apps, you can install them from toltec testing. for remux (assuming you get the latest version), you can launch by swiping up the side of the display we don't expect plato to work yet, and only recently did ddvks rm2 support patches get merged into koreader (for touch support) |

Installation was very easy indeed! I noticed having rm2fb installed breaks things like rien/reStream#31 and https://gist.github.com/owulveryck/4007cbf14e0028f373e4294f66c4ad07 which are reading xochitl memory directly. I couldn't find any advice how these utilities should be adapted to be compatible with rm2fb, is there any guidance on this? |
The framebuffer is exposed as For screenshots, you can similarly grab /dev/shm/swtfb.01 and then convert it raw rgb565 -> png. (to convert, you can use a script like iraw2png.pl in https://www.cnx-software.com/2010/07/18/how-to-do-a-framebuffer-screenshot/ or however you were converting previously) |

No issues with installation. I've only really tried to use Xochitl and KOreader from Oxide. Getting back to oxide from Xochitl can be accomplished by powering off or restarting via the menu, sometimes this dumps you straight back into Xochitl though. One problem I've had is that KOreader seems to crash on auto-sleep from Oxide, does not crash on button-sleep. I'll be trying out Draft as well sometime in the coming days and updating my comment. |
Did you disable the xochitl service and enable the tarnish service? Or did you set xochtil as the default startup application in oxide?
@Witos has been having trouble with returning from suspend as well and has a PR in the works to resolve it Eeems-Org/oxide#114 |
xochitl disabled and enabled tarnish, set no default startup application. Just figured out that it might be that Oxide buffers the input given, past app launches, i.e.

@Brandieee Oh interesting, I've had others report the same thing on the rM1. I've been unable to replicate on my own rM1, but it's very likely happening. On the rM1 we have to flush out the button press queue before switching applications to avoid the same issue. It might be necessary to also do the same of touch input. Could you open an issue on the Oxide repository about this? |

Hey everyone, first of all thanks for the great work. I've tested the package and it works more or less. Some things are not perfect, e.g. koReader works only with pen input, but I can live with that. The only thing that really is a bummer for me is that reStream does not work. I get the following error from the script I had to move over the reMarkable2: A few comments above in the thread, there's this post:
...Which I guess would help. Still, I'm not exactly sure where should I replace |

@FabrizioRomanoGenovese I believe we have an updated build of KOReader in the works still. Just resolving some other issues on it with how it interacts with the oxide package. As for reStream, it doesn't currently support rm2fb as you've found out. I believe there are some discussions going on around getting it to work. I believe you can use https://github.com/bordaigorl/rmview though safely, but don't quote me on that, I don't have a rM2 to test on. I would suggest either opening issues on the respective repositories asking for support, or commenting on existing issues mentioning that you would also like proper rm2fb support. As for you comment about checking to see if rm2fb is installed, yes you can simply run |
If no one gets to it first, I'll push a PR this week to add rm2fb support. |

That would be great! Thanks! Also, is there a reason why reStream isn't available as an |
It's not a reMarkable application, so you don't install it on the reMarkable itself. That said they really should package up the dependencies so you can |

Yeah, part of the application is to be ran on the host PC, but you also need to |
You should open a PR to add it ;) |
This is new as of their rm2 support PR. That small rust binary never used to exist until recently. It'd be great to add it to toltec. |

Hmm, I'm thinking the preload isn't playing well with it. Perhaps we shouldn't have rm2fb auto add to environment for all services and have it be a bit more selective? |
|
It should be possible to disable the LD_PRELOAD directly in the systemd unit by adding a line to some options for rm2fb:
|
|
If rm2fb is failing based on the versions of libs a binary is using, can't we use ldd to figure out if a binary links against the remarkable libs and LD_PRELOAD conditionally? |
that sounds nice - how would we do that for systemd services? |
Well, for any one service, you could override the Exec line and use a conditional expression when launching. It'd be nicer to have something globally applicable though. I'll do some searching. Edit:
Edit2:
Edit3: Before and After work differently than I thought. There may be some other unit relationship we could use instead, but I'm not sure. |
@danshick There is a weaker version of After that can be used. Can't remember what it was called though. |
I think we need |
|
@notDavid I modified two files, If that works for you, the next question is how to set that up automatically when installing rm2fb (and maybe do it for all services that are really busybox files) |
|
@raisjn Great, i just tested it and it works 👌🏼 No more errors. |

thanks for all the testing and help, everyone! rm2fb has been in toltec for a while now, going to close out |
