Testing new server on RM2

[bordaigorl]

The test-new-server branch includes the new server provided by @pl-semiotics . This server solves the only outstanding items of #63. In particular:

• it is compatible with updates 2.6, 2.7 and 2.8
• it is compatible with rm2fb

If you have a RM2, I'd be grateful if you could test the new server and report success/issues here. Reports for RM1 are welcome too.

Please note the old and new servers are known not to work on the 2.9 beta. Watch #86 for updates on that, or see #87 for using rmview with the new built-in server of 2.9.

Instructions

1. Clone or Download the test-new-server branch.

2. From the root directory of the repo, install the test version using

   pip install .

   (mind the final . dot)

3. if you previously installed the /usr/lib/libcrypto.so.1.0.2 library, disable it temporarily by running

   ssh root@RM_IP mv /usr/lib/libcrypto.so.1.0.2 /usr/lib/libcrypto.so.1.0.2.bak

   If you installed a custom version of the server back that up as well, for example with

   ssh root@RM_IP 'mv $HOME/rM-vnc-server-standalone $HOME/rM-vnc-server-standalone.bak'

4. Test rmview with the new server by running

   rmview --install-server

5. Report your experience:

   • if everything works correctly, use the :+1: reaction on this post; leave a comment with RM1/2 firmware version and whether rm2fb was installed.
   • if there was some issue, react with :-1: and leave a comment below for what went wrong.

6. After you finished your tests, to go back to the previous/official version switch to the vnc branch and reinstall with pip install .. Restore the libcrypto library and old server with

   ssh root@RM_IP mv /usr/lib/libcrypto.so.1.0.2.bak /usr/lib/libcrypto.so.1.0.2
   ssh root@RM_IP 'rm $HOME/rM-vnc-server-standalone'

   At the next run of rmview you will be offered to install the server again.

RM2 with Version 2.8.0.98

works with the manually copied libcrypto

still freezes with rm2fb

@vale981 thanks for trying. Looks like it's the old server you are testing? Can you try removing it from the tablet with ssh root@RM_IP 'rm $HOME/rM-vnc-server-standalone' and auto installing it with rmview again? You also have to make sure you are installing rmview before testing, especially if you are just switching branches and you previously installed rmview. This is because pyrcc5 needs to be run to update the binaries in resources.py.

ok that may be it. i'm on nixos though where this is not so easy. i'll try

[vale981]

i did run setup.py build to no avail. shouldn't that suffice?

[vale981]

ahh ok, i did run pyrcc5 manually and now it's stuck at

[vale981]

Ok and now it works Thank you SO much :)

RM2 with Version 2.8.0.98
with rm2fb

Tried the new server and everything seems to work fine.

RM2 v2.8.0.98 without rm2fb

Testing this would be easier for me if I could run this in docker as I don’t want to spoil my system‘s pip. I’ll manually apply the dockerfile introduction to this branch and report my testing results!

[bordaigorl]

@larsblumberg I see...I used the vnc branch as base to only test the server and not get reports of possible bugs in devel. The quickest way to test without having to fiddle with rmview is to just overwrite the $HOME/rM-vnc-server-standalone file on your tablet with the appropriate one in the bin folder of the test-new-server branch (and don't forget to chmod +x it).

maybe virtual envs can work for you

2.9 has a built-in vnc server, maybe that's interfering

@dsborets From the instructions:

Please note the old and new servers are known not to work on the 2.9 beta. Watch #86 for updates on that, or see #87 for using rmview with the new built-in server of 2.9.

TLDR: the server rmview uses makes assumptions about the firmware of the tablet; 2.9 changes the firmware in ways that the server is not prepared to handle and thus it gives up. The new 2.9 also ships with a built-in server; rmview will be compatible with it once 2.9 is shipped as an official release.
