Three key pairs are provided based on the algorithms rsa, ecdsa and ed25519. Public and private host keys are automatically generated in /etc/ssh by the sshdgenkeys service and regenerated if missing even if HostKeyAlgorithms option in sshd_config allows only some. from the /etc/issue file), configure the Banner option: To allow access only for some users, add this line: Whenever changing the configuration, use sshd in test mode before restarting the service to ensure it will be able to start cleanly. Sshd is the OpenSSH server daemon, configured with /etc/ssh/sshd_config and managed by rvice. The instructions can now be made to use drop-in files. P.S.: a one-liner to write the necessary config: defaults write `quartz-wm -help | awk '/default.Reason: openssh 9.4p1-2 added Include /etc/ssh/sshd_config.d/*.conf to /etc/ssh/sshd_config. So, the swrast message is still there, but now I get GL to work GLX_SGIX_fbconfig, GLX_SGIX_pbuffer, GLX_SGIX_visual_select_group, GLX_EXT_visual_rating, GLX_OML_swap_method, GLX_SGIS_multisample, GLX_ARB_multisample, GLX_EXT_import_context, GLX_EXT_visual_info, If you restart Zquartz now (by either killing it, logging out and in again or rebooting).įor me, it was necessary to start the ssh session from an Xquartz xterm session.ĭirect rendering: No (If you want to find out why, try setting LIBGL_DEBUG=verbose) The last line shows the defaults domain: in this case, you then check it with defaults read 11Īnd change it with defaults write 11 enable_iglx -bool true prefs-domain Change the domain used for reading preferences Which will output something like usage: quartz-wm OPTIONS Hope this helps!īased on the comments and suggestions, I think it could work in the following way.
You should now be able to run your GUI applications as expected. You may need to re-run xhost + to disable security & authentication (fine for isolated machines, dangerous for internet-exposed). "startx_script" = "/opt/X11/bin/startx - /opt/X11/bin/Xquartz" įinally, restart xquartz (or your whole machine). "enable_iglx" = 1 # this should be truthy You should be able to confirm it is set by running $ defaults read 11 Next, run defaults write 11 enable_iglx -bool true. My version is XQuartz 2.7.11 (xorg-server 1.18.4). The latest as of this writing does, but it is deprecated so may not in the future. First, check if you have an XQuarts version that supports this feature. /src/xcb_io.c:259: poll_for_event: Assertion `!xcb_xlib_threads_sequence_lost' failed. Most likely this is a multi-threaded client and XInitThreads has not been called Unknown sequence number while processing queue
XRequest.155: BadValue (integer parameter out of range for operation) 0x0 Some other logs you may see related to this are below. You need to allow OpenGL drawing (iglx), which by default is disabled on a lot of X11 servers (like XQuarts or the standard X11 server on Ubuntu). It happens often when X forwarding (via SSH, Docker, etc). The same instructions still apply, just replace the old path with the new if you are from the future.Īlthough the answers here have fixes, I'm submitting another one that I can use for future reference when this issue comes up every other year in my work :)
#Xquartz ssh protocol serial number#
LibGL error: No matching fbConfigs or visuals foundĬurrent serial number in output stream: 22ĮDIT May 5th, 2021: With the release of XQuartz 2.8.0, the configuration path appears to have changed from 11 to 11. I also ran glxinfo (I was trying things I found on forums) and got this name of display: localhost:11.0 Minor opcode of failed request: 24 (X_GLXCreateNewContext)Ĭurrent serial number in output stream: 35 X Error of failed request: BadValue (integer parameter out of range for operation) Minor opcode of failed request: 6 (X_GLXIsDirect)Ĭurrent serial number in output stream: 34
Major opcode of failed request: 149 (GLX) LibGL error: failed to load driver: swrast This time I get the message: libGL error: No matching fbConfigs or visuals found This works well with other applications (firefox, matlab etc.) Ssh -Y normally opens a display on my local machine by X11. The server runs Ubuntu and the local system runs OSX. I am trying to run an executable on a remote server, to which I connect via ssh -Y.
