Ubuntu :: Minimize Nxclient Remote Fullscreen Session Causes Blank Local Display?
Jun 9, 2011
I'm running nxfree to log into my remote xubuntu PC from my local xubuntu laptop since the X protocol was broken.Has been working fine. Recently upgraded from Lucid 32bit to Maverick 64bit Xubuntu.Now when I run nxclient in fullscreen mode, if I minimize the window (or just log out) my local display does not return.I'm left with just the background colour. The windows are still there but not visible. For example I can:* randomly right-click and a menu pertaining to the invisible window appears;* press alt-tab and cycle through the windows but activating one does not display it (it remains invisible);* press ALT-F and bring up the current active (but invisible) application file menu;Basically I press ALT-F and ALT-TAB and close everything and then log out and log back in to restore the windows/panels.

I have a slack 64 13.1 box, that I want to be able to control the monitor of from my laptop. Here's the scenario: I can already control the music remotely via X forwarding banshee to my laptop (banshee shows up on the laptop and music comes out on the desktop). Now I want to be able to open a movie on the desktop's display via the laptop.
Now googling this comes up with solutions for X forwarding, but I don't want it to forward X I want it to display on the desktop.

Has anybody been able to get NX (Nomachine) running on Fedora 10 configured using a shadow session of the local desktop (X11-local). I am experiencing some kind or cookie creation error, perhaps privilege related?
FYI. Normal unix-kde sessions work fine (e.g. Giant on Box) and shadow sessions of an existing unix-kde session works fine too. A shadow session of the local display is a bust.
Here's the error log:
Code:
NX> 203 NXSSH running with pid: 4076
NX> 285 Enabling check on switch command
NX> 285 Enabling skip of SSH config files
NX> 285 Setting the preferred NX options
[Code]....

In 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?

my local box is centos 5.5 running gnome.
I have a eucalyptus instance (vm) running an older version of centos (5.3?). As a vm it has no graphical display. I'd like to run a graphical app there so that it displays back on my local machine.
Used xhost locally and it shows the remote IP (eucalyptus instance) as enabled. On the remote side (eucalyptus instance) I set DISPLAY with:
export DISPLAY xx.xx.xx.xx:0.0
where xx.xx.xx.xx is my local ip address. Oh, I did install X in the vm instance (yum groupinstall "X Window System"). X is installed but not running there (does the point of origin of the x app need to have X running as well - and what does this mean in a vm which is a non-graphicla environment?).
Anyway, I try to run (from remote to local) xclock and get the typical
Error: Can't open display.

which will show a png from GIMP on the screen in fullscreen mode. I was using GIMP and there is an option to save my image as an .h or .c file. I tried .h and it saves it as some kind of very large variable. I want to call this from my own C program and display it on the screen.

I am working on a gym class display screen which was built by others. It is operated under Ubuntu. Everytime I click on Firefox, the page goes to fullscreen, but the problem is that the gym class display is not zoomed to full screen (which is what we need). there are black blank parts on both the right and the bottom of the screen.There is no shortcut key working under firefox either, which means I can't zoom the screen or even enter url for any websites.I checked the gym class website on my computer, everything looks perfect. I think there must be some setting wrong on the operating machine.

since some update to the latest Flash, I've been getting a weird issue. If I'm watching a flash video in fullscreen (via firefox) and hit "esc" to leave full screen, about 20-40% of the time it will screw up the monitor's display of everything. The entire screen gets weird white and colored pixels randomply all over the screen (see the attached picture). Restarting is the only thing that fixes this. I tried logging out and back in but the issue remains. I have two questions:
1. How do I fix this without a restart?
2. What could be causing this?

I have two Ubuntu 10.4 machines (and Ubuntu continues to hide more and more xorg.conf config such that I no longer know where to find it). One is a laptop running dual headed - DP1 is the internal screen, and VGA1 is an external monitor; both are running at 1600x900. The other machine is a desktop running both VGA1 and HDMI1 (which is actually a display port with a DVI adapter) at 1600x900. So in both instances my desktop is 3200x900. I run a VNC server on the laptop and connect to it (via SSH tunnel) from the desktop - when I press the full screen hot key, I get a 1600x900 view of the remote machine on one monitor, and half of my local desktop on the other monitor - the "full screen" only expands to fill one local monitor.
Normally this is exactly what you want when you full screen a web browser, email client, or other application. I'm sure there's some X magic to make it clear what a full screen actually entails, and the vnc client application is just dutifully accepting what it's told. While I would like to keep the normal full screen behavior for regular applications, but when I'm VNCing to another 3200x900 machine, I'd really like full screen to stretch across both local displays. Resizing the window to be "close" isn't quite good enough since I still have local panels at the top and bottom of one display (though I can set them to autohide), plus the VNC client application window border (since it doesn't appear to respect -notitle).
Is there any good way to have X lie to a single application about the "full screen" size? Can I get it to lie to all applications? xrandr --noprimary appears to have no effect.

I'm running a fullscreen display app which shows a 3D scene in OpenGL. The app runs continiously throughout the day unattended.
Here's the sequence of events in how it's loaded:
1) The computer is turned on, and boots into F11 (x86_64)
2) A non-privileged user is automatically logged on
3) The gnome startup applications list contains an entry for a loading script
4) The loading script waits for the network interface (eth0) to ccome up, then starts the display program
This all works just fine, except that about 30 minutes after the computer is turned on and the app starts running, the screen blanks out. Attaching a mouse to the system and moving it around a bit brings the screen back to life. Likewise, SSHing into the machine and killing / restarting the application works as well. Once either of these fixes has been performed, it runs flawlessly for the rest of the day.
I have turned off the screen saver, and set the power settings for monitor shutdown to 'never'.

Posted this in the wrong section so I'm reposting it, is that ok? I installed lxde and logged out and switched to it, but my internet wasn't working (but that's a different thread after I fix this, I was going to try installing wicd) So I tried to go back to gnome, I misclicked and accidentally started a different session. I think it said openbox/gnome, all I get is a blank screen with just the desktop background. It's set to automatically log me in, so when I restart my computer it goes back to the blank screen. How do I get back to the login screen?

I have 2 servers, I set the first one up so that I can remote to it and connect with VNC over ssh by following:[URL]ServerThe 2nd server I did the same, but I cannot connect! When I do, vncviewer prompts for a password and then opens a window of the correct size, but it is all white and then my ssh session is locked! I can't enter any more commands, I have to kill the session.

Slack 13.0 X sometimes fails to start after boot about 50% of the time. linux says "starting X11 session" then I get a blank screen with a flashing cursor and absolutely nothing else. I can <ctrl>-<alt>-<F7> and get a text prompt, log in, and startx from a command prompt. After that, I can reboot once or twice and still get a graphic login, but will soon revert to the dumped condition. I have reinstalled X and KDE twice now as well as deleting my .kde folder. This condition started when I inadvertently ran out of disk space on my /home drive. Since then I have migrated /home to a larger drive and watch it's disk space very carefully.

I've been working on this since last night (a few hours) but can't seem to find what I am looking for. I'll spare you the details of what I've tried already.
Could someone guide me through connecting to my Ubuntu server using a remote X session? The "kicker" is that I want to do this from a Knoppix LIVE CD. So whatever method I am given will have to be something that is common to most Linux distros.
I imagine I will need help with two important steps:
1) verifying that I have an xserver of some kind running on my server.
2) command line statement for starting the Xserver from the remote machine.

I am heavily using remote X11 via ssh (from Ubuntu to Ubuntu).The method I am using is connecting with ssh -X and then running the X application I want to use.Most of the times this is adequate but some times I need to have a desktop view. Running gnome-session in the ssh session, produces a couple of errors (printer and other hardware related) which appears normal but at the end it works. The problem is that desktops end up mixed up with windows from all sessions together and the panels and menus from the last session.
What I am trying to achieve is to have each gnome session in a specific workspace. It will be easy using shortcuts like ctrl-super-right/left to move between different machines. Can something like that be achieved?I know the easy solution would be to vnc to all machines and maximize the vnc viewer in the desired workspace, but this would be really slow and against the linux way of thinking (as is trying to get the remote gnome desktop, but that is another story).Another solution would be to open the gnome panels in a titled window, so that I can see them all at once and distribute them across workspaces. But how do I do that?

At the moment I am using Hummingbird Exceed on a windows PC to display X windows from a Unix server. The actual Exceed tool I use is called 'hwm' which I believe is basically an pc based X Windows manager. I do not need to configure anything other than the client computer name, IP address and screen definition and the server will then allow a connection and display the X windows on the client. I was wondering if there is an equivalent application I can run using Ubunto as a client insted of a Windows PC?

I'm in the process of converting my Windows NT server to an ubuntu server box. I've been testing the server edition in a virtual machine and I only have one problem.
My server computer doesn't have a screen and i was wondering if i can logon to the computer using remote desktop without an active logon session already in progress.
At the moment, I need to be logged on in the desktop environment before i can connect to the remote desktop service in Ubuntu. In Windows, you don't need to have an active logon session to connect remotely (so you can startup a session without needing a screen). I would like to have the same, so i don't need to run to server just to logon after restarting it.
It is probably some service i need to start on system boot, but well, i'm not that familiar yet with linux servers, at least not to do that kind of stuff.
My users would also like to have a visual interface (which is why i installed the ubuntu-desktop from the repository).

I have my local computer, and server.
I log into server, and mount my local computer (folder) via sshfs.

Desktop computer (AMD64) running F12. Nothing unusual about it, stock install. Thinkpad laptop running Windows XP. Putty is installed, I can SSH to Fedora.
If I'm at the laptop, in a Putty session, how can I (for example) type "firefox" and have the resultant Firefox window appear on-the-laptop?
I generally have X running all the time on the desktop because I can't get the wireless network connection to function without NetworkManger (not that I really care because I'm rarely at a console screen and need net access).

I am trying to figure out why the remote X performance of our RedHat 5.3 system is so bad. We have tried using X (Gnome session) from several different X Servers (Windows Xceed, Windows XWinPro, Linux Xnest - both Fedora 11 and Centos 5.3 and Mac OS Xnest) and the system is barely usable. I have monitored the network traffic on the RHEL system and it goes up to 6MB/s at some points, which seems a bit too high for X net traffic?I have disabled ipv6 and any ip_tables modules and that has helped a bit, but it's still not very good.I suspected the network hardware and driver, but I cannot see how that would cause network traffic problems.I wonder if there are any X Server network settings I might check, or whether trying XFCE would be a better option over Gnome. If so, do I have get the xfce group from a CentOS Repo, or is there something better suited to RHEL?
