General :: Display X Apps Running On Host1 And Displaying On Host2 ?
Feb 20, 2010
I have three boxes with lenny debian recently installed. I'd like to be able to display X apps running on host1 and displaying on host2. "xhost +" would do the trick for me if I could get it to work but as far as I can tell it does nothing. (BTW, I'm aware of the security risks. This is not a concern for me. I'm safely behind a good firewall. I'm also aware of "ssh -X" but that won't quite solve my problem. See the long version below.) I suspect that Debian secures the xhost command out of the box in some way but I can't seem to figure out what it is. If that is true and someone can show me how to reset it, or direct me to appropriate documentation I think that would solve my problem.
Here's the long version:
What I really want to do is play xbattle with my kids but I need to be able to display the board to three different screens. In xbattle the command line is: % xbattle -red me -blue host1:0 -green host2:0 {and more stuff of no consequence to my question}
This opens a game board for player red locally, player blue on host1 and player green on host2. Or at least it should. If there is a way to make this work with "ssh -X" (or anything else for that matter) I'll be happy to use that instead, but so far as I can tell "ssh -X" only lets me redirect the display back to the one I ssh'd from whereas I need to direct to multiple displays to run xbattle.
how to configure X11 forwadring over SSH so, that when I open any app over SSH, I get displayed window of a process that is already running on my server (in case its running ), not a new instance of it.
I want to write something that will run apps in succession.For example, you'd click on the app icon,and it would start up one application, have questions alert the user to add a file to do something in that program, run that program & finish. Then open up another program to take that file and prompt the user to do something else with it, and so on.Basically I have a friend who needs an auto, completely easy interface to accomplish certain tasks that require multiple application steps to perform.
Has anyone seen or heard of the following problem? I have a 1in black border surrounding my display. I've been running google searches all day without much luck. My current setup is as follows: Ubuntu 9.10 (64-bit), 24in asus lcd, Radeon 5770, amd phenom 2 x4, ddr3 4gb, gigabyte mb. I noticed the border while running the live cd. I figured it had something to do with the video drivers. Last night I installed ATI's linux driver 10.2. I'm getting my preferred resolution of 1920x1080 over dvi. But i'm not able to use my full 24in. It's like using a 20in lcd.
How to device-mapper multipathing in conjunction with fdisk. I am more of a solaris expert and now trying to grasp linux (red hat). I have a server that I plan to cluster (future assignment) which is attached to a Netapp SAN via emulex LPe11002 HBA. I have 8 paths to the LUN I created and I can see the multipath device (/dev/mapper/mpath1). Below is my multipath.conf file:
[Code]....
Question 1: When I look at fdisk -l, I can see all 8 paths to the same LUN. Although I partition /dev/mapper/mpath1, I can still see that 7 of the 8 still say "Disk /dev/sdX doesn't contain a valid partition table". I would think that all 8 would have this removed. I execute '/usr/sbin/lpfc/lun_scan all' and it doesn't work. I am looking to clean this up...what should I do? It seems weird to have to do it to all 8 paths!
Question 2: Why does my alias, 'db' not show up under /dev/mappers?
Question 3: Is there a way for fdisk -l to display one lun rather than displaying all 8 paths to the lun?
What is the standard procedure (commands) people execute when adding a new lun to a server with multipathing so it is nice and clean?
I am connecting to remote Linux PCs via ssh, to update software and do other tasks. I want to send a notification to the remote PCs screen (eg, "Do not run program X, it is being updated now"), so the users do know what is happening.
Is there a reverse way for ssh -X host so I can connect to a remote Linux machine and run notify-send and it appears on the other display?
I'm running 9.10 with a Radeon X300 video. Two displays, one is 1920x1200, the other is 1600x1200. I'm finding that some apps don't like to be too far to the right (anything past about 2600 x-resolution). If I move a window that far to the right, some of the controls are blank. A good example is OpenOffice. If I move an OO app too far to the right, the text in the main menu items will all be blank. All I see are the icons and the underscores for the keyboard shortcuts. There are other apps that do it, but OpenOffice is the most popular.
I tried re-configuring my displays, and it is always the one on the right. If I stack them top-to-bottom, I don't see the problem. If I reduce resolution, the problem diminishes, until I reduce the total x-resolution to below about 2600.
I require the use of two apps that appear to have similar problems and am wondering if they stem from the same problem. Both have been installed from .deb files and are not part of the official repos.The first is OpenCPN which, when installed, creates a menu entry. The the initial splash screen displays but after clicking OK, nothing appears at all.The second is Inform 7, which was working fine for a couple of days. Now the Game tab is empty. This is the tab that renders a version of the final game whilst working on it.Without knowing the two apps I realise it is difficult to get an understanding of what is wrong with them but it seems to be my machine that's at fault, not the apps as apparently they run fine on other people's machines.What checks can I do to get to the bottom of these problems?
I've just installed BitDefender on my 10.04 netbook, updated and activated it, completed a scan, and found Backdoor.Generic.284566 The thing is, it won't let me delete/quarantine the nasty. BitDefender does give me a warning about my screen resolution being too low (800x600), i believe this may be the problem. The option buttons are not visible on the screen, therefore I cannot use the program properly.(i tried the max resolution 1024x600, but to no avail )
On My OpenSuse 11.3 box, all my 64-bit apps correctly select Western font for menu items, file selection etc.. But my 32-bit apps like Adobe reader and 32-bit version of Firefox display unreadable text for mouse right click, file save and select etc, as if they are trying to use an invalid font or character encoding.C how I configure 32-bit apps to use Western character set, and to find what it is actually looking for ?
im new to Ubuntu and not look at it all in depth yet. I have a small issue. Im using a Toshiba Satellite A200 Laptop. I installed Ubuntu on it yesterday because i was fed up of windows vista. On windows Vista i use to Plug the laptop into a 50" LG plasma and watch online movies and sports. And for the audio i used a USB cable from the laptop into a Pioneer VSA-AX10Ai Amp. My issue is.I plugged the VGA cable in today to test it on Ubuntu. I went into apps/sys/display and all of a sudden the laptop screen just kept flashing on and off. the Tv was saying in the top left 32" and because of all the flashing i could not do anything so i just turned the laptop off. I have not attempted the Audio Via USB yet . I know vista and my IMAC auto picked up the AMP but not on UBUNTU can anyone help me with the Screen issue ??????
I recently installed KDE and began using that instead of Unity (less buggy, IMHO) and it was running smoothly until I began configuring my GTK applications for transition in that. I installed the Oxygen-GTK them from gnome-look.org and set that as my default theme for GTK applications under the KDE appearance preferences.
When I log in, however, GTK applications just use the stock Xorg theme until I run "gnome-appearance-properties" in my terminal.I believe that a fix involving .gtkrc would suffice, but I honestly cannot configure it no matter how hard I try.
After upgrading GNOME to 2.32 in my openSUSE 11.3 x86_64 running graphic applications with sudo is impossible. (that means it worked before upgrading GNOME)
Code:
etam@etam-laptop:~> sudo xeyes root's password: No protocol specified Error: Can't open display: :0.0 From /etc/sudoers:
Code:

What are the ways to check the CPU/memory utilization on my headless torrent box on Seagate DockStar? Besides rtorrent and sabnzbd, I also have Asterisk running on it for occasional telephone calls.
Im comming from ubuntu/mint and one of the things I got used too was doing something like "sudo nautilus" or "sudo gedit" and similar things. In Suse 11.3 I always get errors like the following
(gedit:6115): Gtk-WARNING **: cannot open display: kate: cannot connect to X server Could not parse arguments: Cannot open display:
or similar variations of these.What can I so to prevent this from happening? even if I do "su" and try from there it doesnt always work.I like Suse as it feels more professional then ubuntu, but I am trying to make it as user friendly.
I had some problems which were were already as bugs on which kde4.4.4 crashed and since than I lost this functionality. I cannot say if I have any apps running if they were all minimized as they don't appear on the taskbar. I can switch through them via Alt-Tab.
There are some apps for win that run on wine just with an ordinary install procedure. There are others that will never work at all. But there are also some that wine users claim to have made run by changing some specific configuration of wine, using some trick or even creating scripts on playonlinux.
So if I try to run an app on wine and it doesn't and I don't find any user documentation about some specific trick or config for that app what adjustments can I do to try to make it run? I mean, it's tiring and perhaps foolish to spend hours playing with every possible config in wine frontend without knowing what I'm doing. So what can I do to find out what libraries, configs, tricks or scripts are needeed to make an app run under wine if it didn't at the first try?
and got the same error as before.Has either or both dbus-launch or gksudo changed their behavior os is this a bug. Note that the command does not work with any applications being run as the user gdm.
I have a simple home network consisting of 2 laptops - one is a linux box and the other runs windows and linux with a dual boot setup.I develop my web apps on the linux box but would like to test them out on the windows machine using IE7. I have abandoned the idea of doing this in Linux using wine since in the real world this is unrealistic
I'm trying to run a library compiled in a 32bit Linux (CentOS) environment on my Fedora11 64bit image. I ran into a few issues with dependencies such as gcc, xml2, ssl plus a whole stack more that existed in /lib64 and no/lib where the binary was expecting them. After a bit of reading around, I found I needed to install the .i586 version of each of the dependencies. After adding most of them, I was left with libssl, libcrypto and libxml2. When I tried to do the following
Code:
yum install openssl.i586
I got an error stating it could not be copied due to a conflict with the i686 version. I was going to erase the i686 but it was going to remove a ton of other stuff so I created a symbolic link in /lib to point to 64bit version. Eventually, ldd had no missing dependencies so I figured I was good to go. I now get the following errors when I call my library
./SupervisionServer: /usr/lib/liblber-2.4.so.2: no version information available (required by /lib/libphp5.so) ./SupervisionServer: /usr/lib/libldap_r-2.4.so.2: no version information available (required by /lib/libphp5.so) ./SupervisionServer: error while loading shared libraries: /lib/libpalo_ng.so.0: cannot restore segment prot after reloc: Permission denied
PHP is installed and working and the libpalo_ng.so.0 is in the /lib folder
I have 4 workspaces set up and they appear on the bottom menu bar. Usually I can switch to each and see what's running in each, even if the apps are minimised. Now I can only see what hasn't been minimised, and I can't see or return to the ones that are minimised... System Monitor shows the minimised apps are running... I was poking around gconf editor late the other night and I must have altered a setting but I have no idea which. I've looked through docs etc but can't find a solution.
After downloading a Chrome (for Linux of course) installation package via FireFox. Opening it from Downloads, entering the Administrator password. Then clicking on the " Install Package " button in the " Package Installer " window, I get a message: "Only one software management tool is allowed to run at the same time, please close the other application 'synaptic', 'aptitude', or 'update manager' first." I see no evidence of these apps or any others running & I got rid of the Firefox. Are these " Other Apps " hidden somewhere, how do I determine this?
I really do not know how to phrase this question properly. I am quite unaware of the PC jargon. But I have Ubuntu as the main OS and Mandriva is the second OS on the same hard disk. The boot loader is the Ubuntu. When I want to switch to Mandriva, on boot up I press Shift and then select the kernel.However, if I am on Ubuntu and want to run an application which resides on Mandriva, how do I do that? My fstab file does not even mention Mandriva. However, the file system does show up that file and I can open any files I need by clicking on GUI "Places". But when I try to run any of its applications by clicking the appropriate file on its /bin file nothing happens. A pop-up window briefly flashes and disappears. So my questions are:
1. First how can I change directory so that I am on Mandriva. Can' cd ...something' take me to that file because I see it in "Places" as a 36Gb file system? 2. How can I run an application which resides on that file system e.g., R or Octave which I do not have installed on Ubuntu, without rebooting into Mandriva. 3. Can I do this from command line. 4. And finally, can I do the same from Mandriva i.e., access Ubuntu from it.
I did read quite a bit about mounting files and fstab, but the fstab does not show the file system I am talking about. These are the outputs from Ubuntu os.
I have lucid and jack almost the way I want. I can't get apps like flash (in firefox) and rhythmbox to run through JACK. I've followed some outdated guides on the forums here, but I haven't had any luck.
I set up gstreamer to use jackaudiosink, but no luck.
If you ask me, JACK + ALSA should be the default, with maybe a simplified or automated control system for people who don't want to exploit their might
I hate having to close up a massive JACK patch just to watch a quick movie, or having to close Pidgin so JACK will start.
I've just installed KDE on to my regular Ubuntu 10:04 install and thats all good and well but now when I run my fav GNOME apps in KDE, they look old fashioned like some from Win 95 or 98 type thing. Do I have to install additional GNOME Libraries and if so which ones?
