General :: Ubuntu - Wmctrl Cannot Open Display When Session Initiated Via Ssh+screen
Sep 20, 2010I'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?

Jun 28, 2011I 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.
OpenSUSE :: Opensuse 11.4/gnome - Most Gui Apps Not Working With Gtk Error - Cannot Open Display: ::1:1.0
Jun 22, 2011I 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
Xlib: extension "RANDR" missing on display "::1:1.0".
No protocol specified
No protocol specified
[code]....
(y2base:4872): Gtk-WARNING **: cannot open display: ::1:1.0
Followed by a hang. This is also affecting things like the Xen configuration contexts (creating/managing VMs).

OpenSUSE :: 11.4 Gnome 2.3 Display - CRTC Error That The Display Is Over The Maximum - 1920x1920
Apr 16, 2011I 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.
OpenSUSE Install :: Cannot Open ConsoleKit Session: Unable To Open Session

KNetworkManager will not start automatically in future. If I reboot the system, I logg in successfully. So far the problem has appeared approximately upon every second time I boot up. Rebooting the system seems to take care of it.

Software :: Unable To Make Ptpcam Working - ERROR: Could Not Open Session
Jun 25, 2010After finally getting libptp2 to compile I find that ptpcam does not work. This has worked perfectly fine before with the same camera using Slackware 12.0, I am now using Slackware 13.1 and ptpcam will simply not work. The error is as follows:
Code:
x86_1# ptpcam -l
Listing devices...
bus/dev vendorID/prodID device model
ERROR: Could not open session!
Try to reset the camera.
I have tried to reset with "ptpcam -r", I have also tried to disconnect and reconnect the camera to the USB system, I have tried to reboot the computer, I have tried to use different versions of libptp2 -- all to no avail. The strace shows the issue is apparently a failed ioctl(), although I have no idea why it fails:
Code:
open("/dev/bus/usb/002/004", O_RDWR) = 6
write(4, "1"..., 1) = 1
read(3, "1"..., 1) = 1
[code]....
I have verified that the camera is working in Windows 7 on the same physical computer and I can see the camera from lsusb and dmesg output when I connect it to the USB system. This system is Slackware 13.1, Linux x86_1 2.6.33.4-smp #2 SMP Wed May 12 22:47:36 CDT 2010 i686 Intel(R) Core(TM) i7 CPU 920 @ 2.67GHz GenuineIntel GNU/Linux.

General :: Display The Source Machine During A Remote X Session In The Title Bar?
Aug 8, 2011In the past, when I open a gvim session on a remote machine, the title bar of gvim would show the machine name in brackets. I am not sure if this was done by the remote gvim itself, or the local window manager. In the past I have used gnome2, although I am currently using unity (and finding it rather frustrating). Is there some setting I can change to always force remote windows to display the source machine?
