[Gentoo] DisplayManager userland crashing, no displays
Hi All,
I've been trying the display link driver on Gentoo: Kernel: 3.18.14 Xorg: 1.16.4 Module works (usb, ethernet) but I get no new displays in xrandr and DisplayManager userland is crashing with segmentation fault after a minute or two. There is nothing useful in the log, which seems binary data. Anything I can do to get it work? Thanks Mike |

If you have a core dump from the crashing app somewhere (exact location depends on a distribution), please compress it and send to us as well. Thanks, Michal |

attached log directory, I will reproduce the crash later to get a core dump, where shall I send it, file going to be bigger I guess.

If you have a file to send that's too big for this forum, it's probably the easiest to use one of the file sharing sites and let us know what the link is. Thanks, Michal |

I ran it as root in 64bit both inside xsession and in a separate terminal. 64bit crashes nearly immediately. core dump and new log attached as zip here.

more logs, this time with running it prior to kde-session start, no difference in seg fault, but logs where in install directory as I made it writable for coredump

Thanks for these. I raised it internally to have a deeper look.

Are you sure you are running DisplayLink Manager application as a root? It looks like it cannot communicate with evdi kernel driver through the libevdi library.
Thanks, Michal |
I did both, user and root, but I'll try again.

run as root
