General :: Xwd: Unable To Open Display 'localhost:15.0'

Jul 5, 2011

I'm SSH'ed in to my Ubuntu 11.04 machine and trying to take a screen shot of a virtual display where I'm running (hopefully) Firefox. I get the error

Code:
selenium@selenium:~$ xwd -display localhost:15.0 -out ~/desk.xwd -root
xwd: unable to open display 'localhost:15.0'

I know that I have displayed the right display variable because in an earlier script that runs at system bootup I have

Code:
export DISPLAY=localhost:15.0

Fedora :: Unable To Set Remote Font Server With XSet

Nov 19, 2009

I recently did a clean install of Fedora 11 (from Fedora 10). In Fedora 9 and 10 I used a remote font server so that I could launch HP OpenView over a VPN tunnel. The procedure would go something like this:

*connect to VPN
*xset +fp tcp/<hp_ux_server>:7000
*ssh -X user@hp_ux_server
*launch OpenView

OpenView requires the fonts that are installed on the HP-UX server, hence the need for the xset command. Now since the installation of Fedora 11, I cannot get the xset command to work.

xset fp+ tcp/<hp_ux_server>:7000
xset: bad font path element (#23), possible causes are:
Directory does not exist or has wrong permissions
Directory missing fonts.dir
Incorrect font server address or syntax

I have turned off the firewall to make sure it wasn't blocking the request. But to no avail. I have also had two other people with Fedora 11 machines try this, they get the same error. Were there major changes in the X server from Fedora 10 to 11+?

Ubuntu Networking :: Set Display And Xhost: Unable To Open Display "XXX.XXX.X.XXX:0.0"

Jul 20, 2011

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
xhost +
xhost: unable to open display "XXX.XXX.X.XXX:0.0"

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"

Ubuntu :: "xset Dpms Force Off" Disables Display And Some Seconds Later It Gets Enabled?

Jan 1, 2010

The title pretty much describes the issue. The timespan is sometimes some minutes instead of some seconds. I've tried unplugging every peripherials and disabling the touchpad, killing every non-critical processes, disabling and enabling Compiz, but nothing has helped so far.

I'm running Karmic on an Acer Aspire 8935G-874G100BN laptop with a Radeon graphics chipset.

General :: X11 Forwarding - Error: Can't Open Display: <ip Of Display>

Jun 28, 2011

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'm experimenting with old linux Distributions again, and while trying tostart an x server, I get the following error message:X: unable to open display ''That makes me think that the config file is incomplete, but I would have no idea how to make it. If there is an auto configuration utility that I do not know about for X, it would be great to hear about.

General :: Ubuntu - Wmctrl Cannot Open Display When Session Initiated Via Ssh+screen

Sep 20, 2010

I'm using wmctrl on an Ubuntu machine to manage windows from a script, that I run inside a (gnu) screen.

If I start the screen session from the local machine, wmctrl works fine, including if I completely close the terminal window and issue the wmctrl commands when connecting to the screen remotely via ssh.
Conversely, if I connect remotely with ssh and start a screen, wmctrl doesn't work (returns "Cannot open display") even if I attach that screen session locally from the Ubuntu Terminal.

I guess there is some hidden screen parameter that doesn't get set in a way that allows accessing the display when it's launched remotely -- any ideas what it is and how to modify it from within a remote ssh-screen session so that that the script can access the windows?

OpenSUSE :: Root Trying To Open Flashplayer In KDE Getting Cannot Open Display

Feb 18, 2011

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

Fedora :: Xset Led 3 Does Not Work With FC12

Apr 27, 2010

I have 2 Fedora 12 installs with this problem. Before installing FC 12, xset led 3 worked fine.

The command:

SHOULD turn on the scroll lock LED.

With FC 12, it doesn't.

In Xorg.log, I see: (WW) AllowEmptyInput is on, devices using drivers 'kbd', 'mouse' or 'vmmouse' will be disabled.

(I believe before FC12, I was using driver "kbd".) The man page for kbd shows the options needed for program control of the LEDs.

The new driver appears to be "evdev". I've read some of the HAL documentation and I think this driver uses the file: /usr/share/hal/fdi/policy/10osvendor/10-leds.fdi

I see nothing about program control in this file.

Anyway, anyone have any idea why xset led stopped working and how to go about fixing it?

Hardware :: Xset Does Not Turn Off Backlight?

Jul 25, 2009

Debian Lenny on a Toshiba Portege 350000:08.0 Bridge: ALi Corporation M7101 Power Management Controller [PMU]01:00.0 VGA compatible controller: Trident Microsystems CyberBlade XPAi1 (rev 82)kernel version 2.6.26-2-686On my system, "xset dpms force off" blanks the screen, but does not turn off the backlight. This means that the automated screen off in X does not actually save any power when it blanks the screen.I can turn off the backlight manually using the BIOS tool "vbetool dpms off" (but then I have to turn it back on again manually too).Question 1: is this a problem with the graphics driver interface, or with X, or with the power management driver interface?Question 2: as a workaround, is there any way for me to hook into the dpms off/on that X is doing, and run a script to call vbetool? The best workaround hack I have come across so far is to have a screensaver that calls vbetool, but I was hoping to find something that doesn't require me to run a daemon all the time.
