I installed all the necessary packages for running GUI programs in Cygwin.
Right now, I have to do these things to launch an XWindow program:
1) /bin/startxwin.sh
2) It starts a separate window (the X Window?)
2) In that X Window, ssh -X user#server (this is the remote box where I want to run that box's programs)
3) Then in that X Window, I can launch GUI programs like "xclock".
My question is, can I directly do ssh -X user#server under my original Cygwin window, and launch GUI programs directly, instead of launching a separate X Window and doing it there?
Any instructions are appreciated!!!!
If you want a nice GUI , AFAIK you need an X server to display graphics from your remote "X client".
If what bother you is to manually lauch the X server (?) you may still launch your X server at startup. On my work desktop I do that personnaly (while it don't use X server provided by Cygwin but a commercial one).
Edit: accordinly to the whole comments, You must try with : export DISPLAY=xxx:0.0 , xxx being you the IP address of the machine hosting the x server and add it in your .profile file (or .bashrc file should be fine, but I remember .profile is better for that kind of stuff, nevertheless I may wrong ..)
No, you have to launch X Window server (run startxwin.sh).
"ssh -X" is actually not nesessary. You can set environment variable like
export DISPLAY=Cygwin:0.0
in normal cygwin window then launch GUI programs directly.

I am attempting to install RetroPie as an app on Raspbian Stretch and I am done except for creating a desktop shortcut for it. The problem is that the only way to open RetroPie seems to be running a command in the command line. I can’t do it in terminal because it gives me an error saying that it can’t initialize the window. Is there a way to run a command line command as a shortcut or am I going to have to find another way of doing this?
P.S. Here is the tutorial that I followed to install RetroPie:
https://www.makeuseof.com/tag/install-retropie-app-raspberry-pi/
Probably your shell (on the raspberry) is GNU bash. So read the manual of GNU bash.
You probably want (once) to edit some Bash startup file (such as ~/.bashrc) to define functions and aliases there, and you could add executable shell scripts somewhere in your $PATH. I recommend having a $HOME/bin/ directory containing your scripts and executables, and have $HOME/bin/ early in your $PATH.
I can’t do it in terminal because it gives me an error saying that it can’t initialize the window.
Perhaps you need some display server (such as Xorg or Wayland) running (with a desktop environment or a window manager). You could run Xorg on your PC (on which you could install Linux) and connect to the raspberry using ssh -X then remote applications running on your Raspberry are displayed on your PC. IF your Raspberry is directly connected to a screen (via HDMI) you might run some Xorg server on it.
Is there a way to run a command line command as a shortcut
Yes, by making a shell alias or shell function or shell script. You need to understand how they work and change or create some appropriate file using some source code editor (I recommend GNU emacs, but the choice is yours and you might use any other editor such as vim, gedit, etc...): functions and aliases could be defined in your ~/.bashrc; shell scripts would usually have their own file with a shebang under your $HOME/bin/...
I use Xming for running Xserver on windows machine and that works just fine.
export DISPLAY=<windows_host_IPAddr>:0.0
But I want to export display onto another linux host.
export DISPLAY=<linux_host_IPAddr>:0.0
I am running opensuse and I think Xorg should do the job. But I could not figure out what exactly needs to be done.
If there are any other Xming equivalent packages for linux, please let me know. Thanks in advance.
The only thing you have to do is to enable remote X sessions on your SuSe box. So, login at the desktop, open a shell, and type:
xhost +<IP_address_of_server>
Where IP_address_of_server is the address of the machine where you are starting your actual program (so you allow incoming X connections).
However, this is not very secure, so a better option may be to use SSH and X-forwarding. Again, on your SuSe box, open a terminal and type
ssh -X <account>#<IP_address_of_server>
Then, in the ssh session start your X program without any DISPLAY options, and the output should appear on your local desktop.
In case you have trouble with the -X option, you may try the -Y one, but see the manual page of ssh for details.
I'm working on some tuning of my raspberry. So I decided that midori should start automaticly after autologin.
With startx it works without problems, but X is still to ressource hungry. So I'll start midori with xinit and matchbox.
As test, I use as user "pi" this command "xinit ./home/pi/startmidori.sh" and it works.
So I'll put this into my rc.local file.
There is the command "su -l pi -c xinit ./home/pi/startmidori.sh", this doesn't work. I don't know why, but xinit exit immediately after starting.
How can I solve this? In guides I find this kind of solution, but for it doesn't work. I tryed to run it as root but it doesn't work, too. I've no idea why.
Check this for more information: Running X from The X Window User HOWTO
In general you always need a wrapper and you must run X with root, since it needs raw access to hardware devices.
So I suggest you to install lightweight display manager like LightDM if possible it has almost no footprint and then easy you can set it up to auto login with desired user and run desired window manager like matchbox in your case.
VIM seems integrated to the terminal. Can I open a remote file from the command-line with netbeans? Does it have shell integration? Any further explanation on this so I can better conceptually understand it would be very appreciated.
Few options:
Using ssh -X to forward X. Then you
can start netbeans remotely.
Use sshfs so you mount the
remote filesystem locally over ssh.
You can use then local copy of
netbeans to work on remote files.
Using rsync to have a local copy
The best one - use version control
Yes, you can, providing certain conditions are met!
Using ssh, you can tunnel the display of X-Window applications, meaning you can run the application (the X-Client) on one machine, and have it display on another (the X-Server).
You'll need to launch ssh with the -X option (or -Y, but preferably -X) to allow tunnelling, and then run NetBeans from the commandline as usual:
netbeans MyFile.java
Read about X-forwarding. The link points to a very verbose and detailed howto/tutorial.
I just had my desktop computer replaced. Both my previous computer and this one have Windows XP. In order to work with the many Linux servers we have, I installed Cygwin along with its xterm package. However, I cannot run startx to start the X-window server as I did with my previous computer. I've been looking online to see why startx is missing from my install, but I haven't found anything yet. Any help would be greatly appreciated.
[Does more research] Well, I just installed the xinit package, which I do not recall having to do before. (It may have been a requirement for the xterm package the last time I installed Cygwin.) startx now exists, but I wouldn't say it works. The X-window server it starts creates a window that covers my entire monitor with three terminals within it, unlike the old 25 line x 80 column single terminal window I'm used to. Worse, I can't just spawn child windows like I used to, which was the real power of using Cygwin with X-windows.
OK, after doing more research and getting help from one of my coworkers, I have found a solution to my problem.
What has happened is that, although startx exists, it now starts the X server in fullscreen mode by default instead of multiwindow mode. Looking back, I probably could have copied /etc/X11/xinit/xinitrc to ~/.xinitrc and customized it. However, it turns out that there are other startup scripts for the X server which are easier to modify. (See http://x.cygwin.com/docs/ug/using.html.)
In this case, I took the script startxwin.bat. I then made a couple of changes to startxwin.bat:
I added a drive letter to the CYGWIN_ROOT because my work environment has my home directory outside of the C drive.
I added a "+tb" option to the xterm call to suppress the menubar at the top of the X-window.
The nifty thing is that by going to Start → Programs → Cygwin-X → Xwin Server, I can open a GUI Cygwin X-window without ever opening the standard Cygwin command line. This was decidedly not the case with my previous installation.
I should add that I made these changes after expanding my selection of packages. Instead of just installing X11 → xterm, I followed the recommendations in step 15 of http://x.cygwin.com/docs/ug/setup-cygwin-x-installing.html and installed:
X11 → X-start-menu-icons
X11 → xinit
X11 → xorg-docs
X11 → xorg-server
(This selection picked up X11 → xterm as a required package.) While I see no obvious reason why the directions above wouldn't have worked with just X11 → xterm and X11 → xinit installed, I haven't put that theory to the test, and I have little desire to blow away my current installation and rebuild it to prove my theory.
I hope this helps other people avoid some pain.
Disclaimer: I know this answer does not answer your question directly, but it offers a good alternative.
I use Cygwin + XMing to run remote X applications:
Launch XMing
Start my favorite Cygwin shell (zsh)
export DISPLAY=localhost:0
ssh -X myserver.domain
Run X programs
Works like a charm. The best part is that XMing can neatly integrate X windows into the Windows GUI, i.e. each X app has its own full-right window.
Thanks, this helped me a bit (finding out about installing xinit). That new startx window was really crappy, a friend helped me solve it in another way: by starting with: startxwin.sh instead of startx. Then it looked like the "old" one, and worked much better.
When you installed Cygwin, did you install the full package set? The default is to only install a baseline of packages which may not include X.
Run setup.exe again and ensure the X11 packages are installed. I just click on the little double arrows next to "All" until it says "Install". It may be you chose "Default" instead.
It's better to have a full install since I remember having problems with Cygwin dependencies in the past and now, when I run 'Start', 'All Programs', 'CygWin-X', 'XWin Server', it runs fine, opening up one shell, then 'xterm &' opens another shell.
So I really think you need to install the lot. You could try, at a bare minimum, the whole X11 group (not just xinit) but you may as well do the lot, especially given the powerful commands you get.
I always run Cygwin install twice ... the first time, I just install default packages, and the second time, I install EVERYTHING. The download takes forever, but in this way I always have almost everything I could possibly want. (I like how on Cygwin I can install everything and there are no conflicts, unlike some Linux distributions where there are packages that do the same thing in different ways which can't be installed at the same time. But of course Cygwin has an easier job of this than a full OS ... there's no Cygwin sendmail, for example.)
I have to install Cygwin on a new machine tomorrow, so this question freaks me out. I'm going to die if startx isn't working. I hope it turns out that you're just missing a package. I highly recommend installing everything.
