Folks, I have notice over the last month or two that I don't seem to be able to get the VirtualBox UI to come up on an X11 forwarding ssh connection. I'm seeing the same problem with libreoffice. What's particularly interesting is that 'ssh -Y old.grotty.server', where old is defined as: FreeBSD 10.1-STABLE (GENERIC) #0 r283154: Wed May 20 11:49:55 MDT 2015 virtualbox-ose-4.3.22_2 virtualbox-ose-kmod-4.3.22 (and everything else there is of comparable antiquity) and then running the VirtualBox UI works fine. But running same out to new.shiny.box, FreeBSD 10.3-STABLE (GENERIC) #0 r314889: Tue Mar 7 17:55:43 MST 2017 virtualbox-ose-5.1.14_2 virtualbox-ose-kmod-5.1.14 (and, in a similar fashion, every port on that machine was built Monday, via a local poudriere server) yields this: griffon:/u0/rwa > KDE_FORK_SLAVES=1 VirtualBox debug1: client_input_channel_open: ctype x11 rchan 4 win 65536 max 16384 debug1: client_request_x11: request from 127.0.0.1 38136 debug1: channel 1: new [x11] debug1: confirm x11 ^Tload: 0.20 cmd: VirtualBox 2798 [uwait] 13.09r 0.13u 0.01s 0% 49896k ^Tload: 0.15 cmd: VirtualBox 2798 [uwait] 26.87r 0.13u 0.01s 0% 49896k ^Cdebug1: channel 1: FORCE input drain debug1: channel 1: free: x11, nchannels 2 and it will sit there in uwait sucking down cycles for as long as you care to wait. And, if you walk down the hall and log in via the local console, all is well. Any clues, or further debug info I can supply? All boxes amd64, 10.3-STABLE. regards, Ross -- Ross Alexander, (780) 675-6823 desk / (780) 689-0749 cell, rwa at athabascau.ca The fear of infinity is a form of myopia that destroys the possibility of seeing the actual infinite, even though it in its highest form has created and sustains us, and in its secondary transfinite forms occurs all around us and even inhabits our minds. -- Georg Cantor -- This communication is intended for the use of the recipient to whom it is addressed, and may contain confidential, personal, and or privileged information.
