I recall that X11 provided a number of "fun" programs accessible via unix. For instance, if you use the command xeyes, an interface will pop up of cartoon-like eyes which follow your cursor everywhere.  This still works on my most update version of X11.  But I remember so many more of these fun little commands. For instance, there is:  (A) xsnow which causes snow to fall on your desktop, with the santa option  (B) xsol which would begin a solitaire GUI you could interact with  (C) xmille was something similar, and allow you to play the game Mille Borne  (D) xroach caused cockroaches to crawl all over your screen, with the squish option allow you to click/squish these buggers  (E) xphoon would show the moon as it appears today  (F) xpenguins has penguins appear  (G) oneke had something to do with cats and dogs  Question 1: Does anyone else still use these? The only command which still works for me is xeyes. Which updates do I need to use the others?  Question 2: Have I forgotten any of these types of X11 commands?

I would like to be able to install XFCE to run alongside unity so I can choose, upon startup, which DE I use, without breaking any features of either DE.  Following this:      Note: don't install Nautilus in Xubuntu! This will cause system   conflicts.   I don't want to affect ANY of the features in Unity, i.e. I want to be able to use the two interchangeably, so I can't follow some suggestions of just cleaning out all the old stuff as that would mean using Unity would be changed.   Is this possible in 12.04?

I have a simple one line command which works perfectly in terminal, but does not work in the "Startup Applications" app thing.  The line of code is : xmodmap /home/seph/Code/Ubuntu\ Scripts/Xmodmap  It's not that much of a hassle to copy it from "Startup Applications" and paste it into terminal, but I don't really get why it isn't working.  I followed someone else's instructions to do it in the first place, so maybe I did something wrong?  In any case, wouldn't it be the obvious and logical assumption that it just types whatever you put in it into Terminal?

So I know if I type gnome-terminal or xterm, a new window will be popped out. Then I checked the man page for these two, nothing relevant found.  Then I noticed under Mac you can do it with the program open. But it seems under Linux it's not that trivial.  Does anyone have experience?

Xserver keeps crashing on my general user account both in Unity 3D and 2D. It doesn't do it on the guest account.  That's why I want to reset / rollback everything xserver related, hoping this is going to fix it.  Most answers on this involve sudo dpkg-reconfigure xserver-xorg. However, this does nothing for me (generates no output) and I read in other forums, that it's deprecated.  So, what's the current way to reset all xserver / xorg options; what's the alternative to sudo dpkg-reconfigure xserver-xorg? X crashes during work, not before login or so. And the effect of a crash is, that I get thrown out of the session, not a freeze or machine crash.

I would like to download the alternate installation ISO for the current release, Ubuntu 13.10 Saucy Salamander, but I can't find it on the releases.ubuntu.com website. Aren't alternate ISOs provided anymore?  I need the alternate ISO because Xorg crashes on recent versions of Ubuntu when using old SIS on board graphics.  In fact, I just patched Ubuntu sources and generated a custom package for the xserver-xorg-video-sis driver on my PPA to try fix this problem, after installing with the minimal ISO.

Connecting to a remote Solaris 10 system over X11 I observe inconsistent behavior regarding the used fonts. I am connecting from a  system.  When I connect using ssh forwarding like this  $ ssh -Y mymachine.example.org   fonts work as expected, i.e. the rendering is very nice and programs seem to find all kind of different fonts (e.g. gvim or emacs).  When I connect to the same machine via XDMCP (to the stock blue Solaris 10 login manager screen) and login there seems only 1 fixed size font available. An Emacs from OpenCSW even fails to execute because it can't find the fonts it needs.  It prints that it can't find a font using following specification:  -dt-interface user-medium-r-normal-m   I establish the XDMCP connection like this:  $ XWin -query mymachine.example.org -from mywindowsclient.example.org   My objective is no to get also proper fonts for the XDMCP use case.  How can I investigate this issue? Can I duplicate some configuration which is implicitly used with ssh -Y for the XDMCP case?  How is the font-thing usually setup during ssh-X11-forwarding?

So when i try to use the Xorg command as a normal user, this is the error that it gives me :   /usr/lib/xorg/Xorg.wrap: Only console users are allowed to run the X server   but i don't understand, what are the "console users"?  and when i switch to root it gives me another error :   _XSERVTransSocketUNIXCreateListener: ...SocketCreateListener() failed _XSERVTransMakeAllCOTSServerListeners: server already running (EE)  Fatal server error: (EE) Cannot establish any listening sockets - Make sure an X server isn't already running(EE)  (EE)  Please consult the The X.Org Foundation support       at http://wiki.x.org  for help.  (EE) Please also check the log file at "/var/log/Xorg.0.log" for additional information. (EE)  (EE) Server terminated with error (1). Closing log file.   So what is going on and what are the reason for each of these errors?   UPDATE: and the output of the command netstat -ln | grep -E '[.]X|:6[0-9][0-9][0-9] is :  unix  2      [ ACC ]     STREAM     LISTENING     18044    @/tmp/.X11-unix/X0 unix  2      [ ACC ]     STREAM     LISTENING     47610    @/tmp/.X11-unix/X1 unix  2      [ ACC ]     STREAM     LISTENING     18045    /tmp/.X11-unix/X0 unix  2      [ ACC ]     STREAM     LISTENING     47611    /tmp/.X11-unix/X1

Is there a way to disable scrolling through command history for the Xfce terminal? I don't wish to rely on palm rejection, I'd just like it disabled when I'm using the terminal. Specifically I'm talking about not cycling through previous commands at the prompt when scrolling with mouse/touchpad.

Red Hat recently  in the Bash shell. Some are calling it the "shellshock" bug. Since OS X is built off of Unix, is it vulnerable to attacks that exploit this bug?   As an end user, do I need to worry about an immediate fix? Or is it better for me to wait for an official software update from Apple?

How can I restart X Window Server from the command line?  I'd really like to be able to restart my GUI without having to do a full system reboot.

I installed WSL2 and I want to access WSL2 GUI apps from Windows 10. For this, I installed Xming and start it in "No client" mode. Xming startes, ok. After I open the WSL2 terminal and there execute these commands  export DISPLAY=:0   And after  xeyes   And get error   Error: Can't open display: :0   X11Forwarding checked, yes.

Not totally sure if this is the right place but here goes.  I understand that you are able to use X11 to ssh to GUI's and view them, without the server having a full on GUI system running/installed like gnome or something.  My end goal is to be able to "broadcast" my coding sessions online, so people can view them online.  Right now I have set it up so that a restricted tmux session will basically always be mirroring my own personal tmux coding session window.  So if you ssh onto the server on a restricted account, you can hop onto the restricted session and follow my coding.  However, I want to be able to let people watch this from their browser.  I suspect that the best way is to have some terminal emulator on x11 running on my server attached to the tmux session..and then somehow have the browser view that terminal emulator?  I'm not really too familiar with this domain, so does anyone know if this is possible?  Or is there a better approach I should be taking?  Note that I code entirely on a remote headless server that I ssh onto.

I was calibrating my touch screen, and saw that the best tool around was xinput_calibrator. So I used it. It have two options (one of which did not work), so I am here for the second. It says I should execute this command "in a script that starts with your X session":  xinput set-int-prop "3M 3M USB Touchscreen - EX II" "Evdev Axis Calibration" 32 14410 2146 14574 2115  So I tried ~/.xinitrc, ~/.xsession and ~/.xsessionrc, all of which did not exist. So I created them and the exact content was this command. The first two files made my logins fail (after I login, I fall back to the login screen).  With the last file, the calibration was functional, but only after logging in...  I need that command to run before the login dialog shows up. I thought of adding this command to the end of /etc/X11/xinit/xinitrc with no result (nothing changed). Also, I tried to add it to the end of /etc/X11/Xsession.d/40x11-common_xsessionrc (after inspecting some of the files), but the result was exactly the same as adding it to ~/.xsessionrc.  How can I make this command run before the login screen shows (is this before the window manager starts, or before the X session starts)?  (I am running Kubuntu with the default window manager, if that matters)  UPDATE As I am using Kubuntu, my display manager is kdm. As the accepted answer suggests, I edited the file /etc/kde4/kdm/Xsetup, and as mentioned  I added the command before the command that is there by default. And it works like a charm :)

What command line tools exist to list and manage X server grabs? (That's grab as in key and pointer grabs, i.e. restricting the use of a particular key or mouse button to a particular application, or constricting the mouse pointer to remain in a particular screen area.) I'm looking for a hypothetical xgrab utility that would show things like  Key     0x00f00ba5  0x123   0 Button  0x00f00ba5  2        Pointer 0x00abcdef     meaning that there has been a call to XGrabKey(display, 0x123, 0, 0x00f00ba5, ...) and so on with XGrabButton, XGrabPointer, XGrabKeyboard, XGrabServer (if possible). The display format doesn't matter, what I want is some way to see who's grabbing what, and possibly some way of revoking these grabs (if it's possible, I'm not sure if the X11 API allows that).

I am really annoyed because I recently switched to GNOME and I lost a command, Super + Q, that I had with a special application.   Now, it shows the side menu (Ubuntu Dock) and numbers the applications.   I tried to change it at the keyboard options but the command is not even there!   I assume that it's a GNOME issue. But I am not very experienced and it is really annoying that I can't see the command in the Keyboard Command window.  This in on a XPS 13, Ubuntu 17.10, GNOME 3.26.1.

I've installed emacsformacosx on my OSX box.  I'd like to shove my macmini in a data center and run it headless.  I've gotten x-windows working.  If I run xeyes, it displays on my Windows 7 client.  Emacs works from the command line on the osx box.  However, if I start up emacs from the windows client, it pops it up on the server instead of the client.  What am I doing wrong?
