i just downloaded Nethack from [URl], and moved the extracted files to /usr/games. Then i changed the permissions in /usr/games/lib/nethackdir so i could access the lib files.
Nethacks runs in X, and it runs in terminal when im root. But for some strange reason it does not run in CLI when im not root, i get the message "Error: Can't open display:".
I have the following scenario that doesn't seem to work normally. I have a windows 7 pc from which I am using putty to connect to my other linux servers (all running redhat 5 and 6). So here is the scenario that works and one that does not work. And I'm trying to figure out the one that does not work. Scenario that works:
From windows 7 (putty) I ssh into Linux_Server_1.
echo $DISPLAY
localhost:10.0
I run xclock and I see it pop up on my windows 7 pc. I am using xming on windows 7 to help me populate the display from linux to windows. One that does not work:
From windows 7 (putty) I ssh into Linux_Server_1. Then from Linux_Server_1 I ssh into Linux_Server_2.
echo $DISPLAY
<no output>
I try to setup $DISPLAY with localhost:10.0 or 0.0 or even my windows 7 pc ip address:0.0 ....etc Then when I try to run xclock I doesn't work.
I get these error messages: Error: Can't open display: <ip of display>
Also as a side note all our Linux servers are sitting on one subnet. My pc is sitting on another subnet. I use vpn to connect to the subnet where the servers sit from my pc.
i have just installed a redhat linux entprise 5 on my machine. I am trying to install a software and when i run the #install.ksf , my installation gets aborted and my install.log file shows this,
Error: Can't open display !
Environment variable 'DISPLAY' must be defined.
When trying to run X apps from terminal command line I getCannot open X display `:0.0'error.I tried export DISPLAY=0.0What do I need to do to permently fix this problem?
View 1 Replies View RelatedI was trying to remotely log in to my desktop which uses 11.3 from my laptop via ssh. For some reason I get an empty field for the command echo $DISPLAY. and as a result an xclock command results in error: can't open display. I tried to set it to localhost:10.0 and I get: Error: Can't open display: localhost:10.0
I've tried :0.0 and I get: Invalid MIT-MAGIC-COOKIE-1 keyError: Can't open display: :0.0 ssh used to work about a week ago before I performed various security updates. I was wondering what' the solution to this. I checked the /etc/ssh/sshd_config file and ssh_config file both have X11 forwarding on. Can anyone with more experience out there give me any ideas?
When I attempt to use Putty for xterm (to run DBCA for Oracle) I check x11 and put my IP Address in the Display field of putty. However, when I then try to execute ./dbca I receive the following:
Xlib: connection to "localhost:10.0" refused by server
Xlib: PuTTY X11 proxy: wrong authentication protocol attempted
Error: Can't open display: localhost:10.0
I notice the following when logging in to the server as well.

So I just installed 32-bit Squeeze. I've done exactly two things since booting into the first install: pt-get install gtk+2.0, and ./firefox, so unless gtk did something, this might be an easily fixable problem with Debian itself. After installing gtk and trying to run firefox via command line, it tells me
Code: Error: cannot open display: :0 I googled a bit and couldn't come up with a solid solution, but the problem seems to be around other places. Any idea how to fix this?
For awhile I have had this issue with the command line and every time I try to complete any command that requires GTK graphics, It always returns the error "Error: cannot open display: 0:" The "EXPORT display" command that I normally use to fix this issue is not working. The only issue that I can think might be the cause for this could be my upgrade to natty (which was in fact a clean installation), or when I edited plymouth so that the startup and shutdown animations would match my laptop's native resolution (by the way I would also appreciate it if I could do the same with the startup animation, only the shutdown really works). If anybody know how I could resolve this issue I would greatly appreciate it. Oh and for specifics on my machine, I am using an ASUS N82 with an NVIDIA GEFORCE GT335M graphics card, running Ubuntu 11.04.

I also had ever tried all methods they mentioned, but my problem is still there. I am using a MAC OS X 10.6 ssh a remote redhat server. I hope to see X of redhat on my own MAC. Below is what I've done: 'MAC_ip' stands for my mac; 'redhat_ip' stands for redhat server.
1) ssh to redhat server

I recently installed opensuse 11.4 on a remote server. It has GNOME installed as a desktop. The problem I am experiencing is that when logged in through VNC, most of the GUI apps are not functioning, especially ones that require root privs. Example: The Add/Create users context does not function. After you supply root pw, nothing happens. If you launch it from a terminal, you see this:
jjmuw@g01:~> xdg-su -c /sbin/yast2 users

View 4 Replies View RelatedI have transmission-daemon running on a remote computer, which I can access via ssh. Daemon is managed with an /etc/init.d script, and the problem is that when I'm logged into the remote computer over ssh, any attempt to start/stop/restart the daemon results in "Cannot open display:" error.

I've read a number of topics on similar issues with X applications, but the question that is bugging me -- why would a CLI app request access to display?
There's also Webmin web-interface available, and everything works just fine if I use it to control the transmission-daemon. I should also probably mention that some time ago the script worked ok, but mysteriously broke, though no significant changes to the system had been made (i.e. only tweaks to separate applications' config files).
The script in /etc/init.d looks like this:

We have a digital signage appliance built on SUSE 11.3 with a LAMP server that uses the flashplayer application to play a .swf file from localhost. It is a AOpen GP7A mini pc that has the nVidia drivers loaded. We have lots of customers that have been running the exact same system for over 6 months (we image the drive for each sale).
For some reason, my last customer is seeing the following problem shown below, and this linux configuration is way over my head. Everything else is working (local LAMP server is working, communicating with our production servers to get information works, etc). I have verified that it is screen 0 that is running (at least it shows with Ctrl-Alt-F7). I thought that it may have occurred because of updating the software with zypper up. I had the customer rebuild from the image being careful not to upgrade the software. The result was the same. The pc is a newer version compared to my bench pc, but there are multiple other customers running that same version just fine. So I am not sure if it is
The command is issued by a php script that is run in a root cron job. As I said, it works great on all other customer pc's including my bench system. I also tried to execute the command on a ssh terminal as the root user with the same result. I also upgraded my bench pc and it still worked properly.
The command being executed is sudo env DISPLAY=:0 XAUTHORITY=/home/svision/.Xauthority flashplayer http://localhost/flash/sign.swf &
the result (when run in terminal) is: No protocol specified (flashplayer:15077): Gtk-WARNING **: cannot open display: :0
I have a fresh install of OpenSUSE 11.4 64bit and I have installed the AMD Display drivers for my Radeon HD 5970. Everything seems to be working quite well. I have a multiple monitor setup (1280x1024 monitor and a 1920x1080 monitor).
I have my primary display set to 1920x1080, however when I try to enable the second display, I get a CRTC error that the display is over the maximum (1920x1920). If I enable both monitors at lower resolutions, there is no problem.
I have done a fair bit of reading and have been unable to determine where this maximum is set, or how to change it. I'd like to be able to run both monitors at their native resolutions.
I have configured an instance in AWS EC2. I am trying to set the display back so I can run x apps. I login using ssh -xy -i...
export DISPLAY=XXX.XXX.X.XXX:0.0
echo $DISPLAY to verify

I have commented out nolisten tcp as suggested HERE I have modified /etc/gdm/custom.conf as suggested HERE Actually, the last suggested modifying /etc/gdm/gdm.conf, but that file didn't exist, so I added the line: DisallowTCP=false to /etc/gdm/custom.conf I rebooted, and still I get: xhost: unable to open display "XXX.XXX.X.XXX:0.0"
I have a while(1) loop, and the error is: glibtop: open (/proc/stat): Too many open files This error occurs after about a half hour to an hour of running. I've tried running this multiple times, both with using glib_close() at the end of the loop, using glib_init() and glib_close() at beginning/end, and just using glib_init(). The strange thing is these have no effect on the actual glib_get functions.
