I am trying to ssh into a remote Linux server using x11. I found that Mountain Lion no longer supports x11 when I upgraded, so I installed Quartz. However, my terminal commands are not working anymore. Here are two important terminal commands that no longer work for me.
I did a Google search and looked elsewhere on Stack Overflow, but didn't find what I am looking for. Namely, I was hoping there are some new commands that work with Quartz in place of the standard x11 phrases I have been using. I tried these after I installed Quartz on my machine, and it didn't work. I just taught myself these x11 commands on 10.7 when 10.8 just came out. Here are a few examples.
1.
ssh -X username#serverlocation.com
2.
./configure -- this/is/an/example/directory --enable--gdb --with-x -with-x11 --with-term --with-nogui
If anyone could tell me how to get this working with Quartz on Mountain Lion, I would be grateful. Otherwise, I would have to run a VM on my Mac with either Windows and putty in, or try to figure out how to use x11 on my Ubuntu machine.
Have you logged out/in after installing XQuartz? XQuartz is just a distribution of X11 and is completely compatible with what was previously included with the OS X.

Currently, I have two machines, one with Ubuntu in the company and one with Mac OS at home. Sometimes I would like to work at home while accessing the Ubuntu machine in the company. I can ssh into the Ubuntu machine and navigate and compile there. However, when I actually want to edit some cpp source codes, I realize that the editor (VS code) is actually opened in the Ubuntu machine, so I cannot view it from Mac. What should I do if want to edit files remotely on my Mac through VS code?
Though many of the answers mention using version control tools like git, it can be hard to use in my specific case. The problem is that the building environment of my company is Linux, so most of the building tools I have can only run on Linux. This means that I can only compile my source codes in Linux. If I use git, then every time I want to compile and debug my codes, I have to commit and push with my Mac, and then pull and test on Linux. This can be time consuming if want to incrementally modify, test and debug my codes.
Use some version control system like git. Then you might edit and compile at home (provided your code is portable between Linux & MacOSX, e.g. because it is POSIX compliant).
You could install some X11 server on your Mac and use ssh -X to access the remote Ubuntu machine (then run a GUI or editor remotely, e.g. ssh -X remotelinuxhost.company.com emacs). However, that requires good bandwidth and latency between your home computer and the remote one.
BTW, you might use some other source code editor, like emacs (it is capable of remote editing) or vim.
Since Linux and MacOSX are both POSIX systems, it is usually (but not always) easy to port source code from Linux to MacOSX and write source code compilable on both systems. BTW, many Linux frameworks (e.g. Qt, GTK, POCO, Boost, etc...) and build systems are usable and ported to MacOSX. Some Linux system calls (listed in syscalls(2)) are not available on MacOSX (e.g. signalfd(2)...)
Of course you could install Linux (perhaps inside some VM) on your Apple laptop.
I have installed NetBSD 6.1.5 with full installation setting. However, when I run startx it says no screens could be found. So i tried "X -configure" and then "X -config ~/xconfig.conf.new" and I was brought to a very generic screen with a black x crosshair, but I was unable to exit this using the suggested ctrl+alt+backspace, so I had to force power off and check if my keyboard was recognized in the conf file generated, which it was. I have installed xdm, xterm, Xorg, and other X programs.
I am not familiar with setting up desktop environments from scratch. I am a newb who is used to Ubuntu esque installers doing that stuff for me.
Would someone be able to walk me though the installation or point me to a link which explains a step by step process?
What happens if you rename your xorg.conf.new to /etc/X11/xorg.conf? Does startx or xdm work then?
Are you running this inside a VirtualBox or other emulator?
I have NetBSD on a Thinkpad T420 which I occasionally boot into Windows, and I've setup VirtualBox to be able to run the same NetBSD install when I'm in Windows. The key difference in the xorg.conf file is in the Device section:
Section "Device"
Driver "vesa"
EndSection
Also I've found the free version of http://mobaxterm.mobatek.net/ very handy - I use it to ssh into the virtual NetBSD box and then run X apps and have them display on the Windows desktop.
Final note - you might want to look out for the NetBSD-7 RC1 which should be out 'Real Soon Now', as there are some very handy improvements, including better support for most modern display hardware :)
I found that running startx from any directory with a .xinitrc file gives strange behavior in amd64 6.1.5 and 6.1.4. Delete (or rename) any .xinitrc files and try
xinit /path/to/windowmanager
Please read Chapter 9 of NetBSD Guide:
http://www.netbsd.org/docs/guide/en/chap-x.html
Section 9.9 discusses installing various Desktop Managers/Environments.
It turns out that I could run "X -config xorg.conf.new" as root on host and then ssh using putty to manually launch windows.
I have Enthought Canopy installed on a machine running RedHat Enterprise Linux 5. I installed it successfully and can verify it runs.
I would like to be able to use it remotely from a windows computer, I have installed putty + xming for X11 forwarding. I can use regular applications like gedit and firefox fine. However when I try using canopy by launching ~/Canopy/canopy an empty gray box for the welcome screen appears, disappears after a few moments, and canopy exits with no return error without having started.
When I ssh with X forwarding from another linux computer, I can use canopy just fine.
There is no error code, I don't see any debug flags and I can't find any log files. I really have no idea why I cant access canopy with putty and xming.
I am trying this as a solution for interns so they can use a machine with access to our datafiles from their windows computers.
I highly appreciate any and all help.
Canopy needs some features not provided by XMing and a few other X server implementation on windows. See the following article for more details:
https://support.enthought.com/entries/21873380-Running-Canopy-Linux-via-remote-display-VNC-remote-X-display-
In short, use MobaXterm ( http://mobaxterm.mobatek.net/ ) or VcXSrv ( http://sourceforge.net/projects/vcxsrv/ )
EDIT: newer versions of Canopy have fixed this bug and should work fine with XMing
I am using OSX 10.7.5 from my MacBook Air to login to remote Linux workstation, running Suse (/etc/issue: SUSE Linux Enterprise Desktop 11 SP2 (x86_64) - Kernel \r (\l))
Everything was working fine until I started to play with macports latest X11, XQuartz XWindow System (XQuartz 2.7.4 (xorg-server 1.13.0)). By default OSX 10.7.5 comes with XQuartz 2.6.4 (xorg-server 1.10.6), however I've installed and made default XQuartz 2.7.4. I am now observing two issues:
(1) When logging to my remote Suse box (this is done via VPN tunnel btw, not sure if it matters), via 'user1> ssh -X user2#wks01' I am getting
Warning: untrusted X11 forwarding setup failed: xauth key data not generated
This (at least appears) to be traced to the fact that there's no 'Security' extension on the new Xquarts server. Traced via ssh -vvv option, and then due to the fact that xauth is failing, so running it separately on MacBox, or remote Suse gives:
user2#wks04:~> xauth generate "$DISPLAY" .
trustedxauth: (argv):1: couldn't query Security extension on display "localhost:10.0"
'ssh -Y' logs in without warning
(2) What is also interesting, that in both ssh modes -X and -Y I am able to open and forward to my display any X-application that I have checked, including xclock, xlogo, xcalc and even eclipse. However running simple 'xterm' results in a hanging job (i.e. appears running), but xterm never displays on my Mac.
While rolling back to will XQuartz 2.6.4 probably help with the issues above (as all the above operations worked smoothly before), but I am curious now to understand the root of the matter.
Thank you in advance for your help,
Dmitry
Studying vision, I would like to play with the Microsoft Kinect.
Can I use it on my Mac?
I have not found any Library for Mac and fear virtualization on my laptop to use Linux.
I've accessed Kinect data on OSX using openframeworks and the ofxKinect addon (which uses libfreenect and libusb).
It's not the only option, just I've used and worked 'out of the box'.
Try downloading the Zigfu Dev Bundle for mac (http://www.zigfu.com) - that should get you up to speed with kinect development on mac.
Using Kinect on Mac is as easy as ordering Latte.
But there is also a lot of confusion on the Internet and sites that seem to be old and give you the wrong advice such as installing a separate sensor library in addition to OpenNI. Just go to the basic website and download SDK for your MAC:
http://www.openni.org/openni-sdk/
You might need to have prerequsities though I assume you have already installed them, such as:
sudo port install libtool
sudo port install doxygen
restart comp
sudo port install libusb-devel +universal
Troubleshooting:
"sudo rm -f /opt/local/lib/libusb-1.0.0.dylib"
"sudo port clean libusb"
"sudo port install libusb +universal"
No need to compile anything. You should be able to run ./Samples/Bin/SimpleViewer right away after you run sudo ./install.sh.The PROBLEM might be that you have already tried to run it unsuccessfully and put a camera in the wrong state. I have seen errors such as USB intercase cannot be set etc. as a side effect.
Running your code in Eclipse is a different story and may require a few extra steps and changing your Ubuntu code (using openni namespace, different includes, etc.)
