Current Version does not work on Dell D3100

[displaylink-mlukaszek]

@daugustin I cannot promise any ETA. We definitely do plan to extend support to Ubuntu 16.04, which as you know it's due to be out in about a week.

[displaylink-mlukaszek]

This should already be fixed on devel branch - but DisplayLink driver would not work with this branch yet as commit 09b525b changed the signature of evdi_connect. A build from devel branch witch this change reverted might work though. Let us know if you try it. Thanks!

[daugustin]

Oh sorry didn't really realize the old "master" branch there (which has nothing really changed) so all my comments above apply to the devel branch. I couldn't get the patch reversed on first try as it seems a lot of things changed. I need ba9e54f though, because of the changes for 4.5.

Is there a new release of DisplayLink planned for the new evdi module?

[mclei-asw]

I have the same problem, kernel 4.5.0 and Dell D3100. On kernel 4.4.0 and older evdi it was working.

[daugustin]

@f3l1x I think this is a different issue
The error here is

gcc: error: unrecognized command line option ‘-fstack-protector-strong’

which is a GCC 4.9 option.
For what I have found, Mint 17 only ships with GCC 4.8

[f3l1x]

@daugustin Thanks... But, how can I fix it?

[sinfomicien]

The patch i made for my openSUSE installation, can be reused for other linux distribution i think:
https://github.com/sinfomicien/displaylink-evdi-opensuse

The patch is based on codesource i grab here, and apply only for kernel 4.5.0 compatibility

[daugustin]

Thanks @sinfomicien, I used that to update my ebuild

I successfully tested the first version from 2015 with the patch and it worked on 4.5.

@displaylink-mlukaszek Are there any ETAs for a new displaylink driver so we can use the newer evdi module?

[displaylink-mlukaszek]

Closing, this is now shipping in Ubuntu 1.1.62 release.

[jcaesar]

I'm seeing something similar https://gist.github.com/jcaesar/c6d93c70ae1d82689b96924d573ecc95 with version 1.1.65 (I can display stuff, but some applications have slideshow-level-performance.)
Should I open a new bug for this?

[displaylink-mlukaszek]

@jcaesar Yes, please raise this on our forum. It would be great if you could attach logs and, even better, record a short video where the problem can be observed. Thanks.
