Fedora :: Using A Remote X Server As A Third Monitor?
Jan 20, 2011
I'm currently running a dual-monitor setup using gnome-display-properties. I have a dual-head video card.
What I would like to do is to use a remote X server as a third monitor. I installed Xdmx and Xinerama, but I can't figure out how to get Xinerama up and running. Is there any documentation that tells you how to configure Xinerama on Fedora 13? Is Xinerema compl

I am using Ubuntu 9.10. I can do remote desktop into the system with a monitor attached but when I reboot the system without a monitor attached I am unable to do remote desktop into it.
I want to use this system as a headless system and only use remote desktop to control it.
So I guess I need to start X and gnome without a monitor attached.
What do I need to do to get this to run?

I have been trying and trying to get remote desktop to work without using a monitor connected to the server. I have the server set up to where it can be rebooted and everything perfectly fine remotely (as long as it has a monitor). Unfortunately, I need this to be not connected to a monitor-PERIOD. I would think this would be something to be working out of the box, but I guess not.

How do I do this in 10.4? I need to be able to Remote Desktop into my server over SSH but can't because I don't have a spare monitor on hand... and Ubuntu won't start a desktop if it doesn't detect a monitor.

Ubuntu Desktop 10.10 boots with disconnected monitor with a screen resolution of 1024x786 ... which in fact is great - other distributions won't even boot ...
How can I change this resolution? ... cause I'am operating my system via VNC and preferably set it to something higher.

I ran the following commands on my ubuntu desktop :
xrandr --output VGA-0 --mode 1680x1050
xrandr --output VGA-1 --mode 1680x1050
xrandr --output VGA-1 --left-of VGA-0
This gives me dual head. I have a second machine on the same 100mbps network that is also running Ubuntu. I want to run X on that machine and have it's X session as a monitor in xrandr, so I would add something like this :xrandr --output REMOTE-1 --right-of VGA-1Is this possible?

I have an old computer that no longer has a monitor (it just broke) and I want to access it through my laptop through remote desktop. It has Ubuntu 11.04 on it but I don't know how to set up Remote Desktop on it without a monitor. I have a mouse and keyboard though. Is it possible to set it up without a monitor?

I am unable to run remote desktop from my fc 13 server, to my laptop. I have read the remote desktop setup and added port 6000 to firewall, added host name of server to xhost (nick@192.168.1.110). Added the line to /etc/gdm/custom.conf like in fedora guide (DisallowTCP=false). But i still get the error
[nick@pc1 ~]$ xclock
No protocol specified
Error: Can't open display: 192.168.1.101:0

I'm trying to list installed packages on a remote server. I don't see a way to do this with either yum or rpm.In particular, I'd like to list installed packages on a remote server, and list only those packages installed from our own repo

My X crashes when I...
1) ssh to a remote centos server using X11 forwarding
2) open the virt-manager remote application (the virtualization management app)
3) Open the remote console
Just to be clear, my local X11 crashes. I get back to the log in screen.
I get in my Xorg log:
Backtrace:
Fatal server error:
-Is this enough for a bug report?
-How I can make X dump a core file for better debugging?
-Do -debug RPM packages still exist, and if so, should I install one for the X server and will this help with debugging, and if so, how do I install it.

I enabled remote desktop on my Fedora core machine.
SELinux is disabled, as is iptables.
I used UltraVNC to connect and it worked.
However, after I came back overnight, I tried to connect and it failed.
I received a "Failed to connect to server"
Found that the machine had rebooted.
How do I get it the Remote Desktop function to start as a service? I am new to Linux.

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+?

I use XDMCP from an old laptop to login remotely to another computer which is running Debian 6. This seemed to work fine in Debian Lenny, and the laptop screen would switch off after a period of inactivity as I expected. Now the laptop screen blanks after inactivity, but the backlight never switches off.

We recently had a vulnerability scan done on our network and one of the vulnerabilities was that the dns server discloses the remote host name when using hostname.bind.
Is there any way that we can stop this from happening? Our name server is a Fedora 11 machine.

How can I logged the external or public IP of the remote client?

I am attempting to write a very basic script that monitors a server's load and automatically emails an administrator upon the load reaching a certain threshold...
1.) `uptime | awk -F ' ' {'print $10'} | cut -d ',' -f1 | awk -F '.' {'print $1'}` -- the output from this command results in a decimal figure, so when that value is parsed and placed in an if statement, the value is not seen as a number. load-monitor.sh: line 9: [: 4.96: integer expression expected/How can I allow a number like "4.56" to be seen as an actual number within the if statement and be compared to 4, for instance?
2.) I am running a cPanel server on CentOS 5.4 -- when I run mail -s "SUBJECT" $EMAILADDRESS the command just hangs, and stracing the process shows it stuck on a read syscall.
3.) If I wanted to write this script in PHP, I have one primary confusion -- how can I mimic the functionality of obtaining the output from uptime via awk, etc. so that I can determine what the server load is at a given time? Which PHP function(s) would assist in that regard?

I am facing problem with the fresh installation of Fedora 11. (I have moved from Fedora 9). When I try to view videos on ..... or use the Cheese Webcam Booth, I get blurred lines on the screen and I am unable to see any video or pic.
Also I noticed that the when i go to System > Preferences>Display, it shows me UNKOWN MONIOR.
However, if I got to System>Administration>Display and enter the su password, it shows me correct monitor and the graphics driver.
I am not sure if my original is related to the Unknown Monitor.
I also tried to install Nvidia driver but it crashed the xserver and I had remove the driver.
My Monitor is LG 700E and Graphics card is from intel. as I am not able watch any video.

I am having problems getting my external monitor to work. When I plug in the monitor, both the laptop screen and the external monitor go black. When I unplug the monitor, the laptop screen works again.
When I startup with the external monitor plugged in, neither screen works or teh computer hangs or something.
I have had the external monitor going on a couple of occasions. I did manage to configure my monitors through System Settings > Display. I turned off the laptop monitor as I just want to use the external. But after rebooting, things didn't work.
I have a Thinkpad E420, Fedora 15

I have an external monitor connected to my laptop (extended display). I always drag the Totem player from the laptop screen to external monitor to watch video files. I wonder, if the Totem player can be set to open in the external monitor automatically, everytime I open it?

My software and hardware information are as follows. I have Fedora 12 and KDE 4.4.5 installed on a Dell Vostro 1500 laptop. I believe it's a 64 bit processor; it's an Intel Core 2 Duo CPU. The external monitor is a Dell as well.
My problem is that my system does not seem to be detecting an external monitor that I have connected. Everything else is working just fine; however, I would like to have the option of attaching an external monitor. When I plug the external monitor into the laptop, the external monitor remains black and appears to be in power save mode. The results of xrandr -q (with or without the external monitor attached: it doesn't appear to change) are as follows.
Code:
How can I get my laptop to recognize that the external monitor is even connected? Let me know if I can be more specific or provide additional details.

I just upgrade to F14 from F10 on a dual montor setup. Firefox behaives differently on F14 than on F10.
On F10 it followed the mouse pointer's location and show up on the correct monitor
When maximized at close, it is always displayed on the left monitor. When not maximized at close it will open on the monitor where the mouse pointer is located.
About minimize/maximize Firefoxe before closing and it seems to work in some case, but not for me.

I have a low powered headless box (DLINK DNS323) running linux that I keep in a back room at home to handle large file downloads. It does not have X installed. Everything is handled at the command prompt through an SSH link. In the most common case, I log in from a remote location (perhaps a coffee shop), start the download, then disconnect and go about my business.
If I try to download from a free account of rapidshare, filesonic, or some another file service there is a manual handshake process (decode a captcha, wait for 60 seconds, etc) that requires a graphical client to complete.
I would like to somehow navigate through the handshake using my laptop (running Firefox) (perhaps through a proxy on the DNS323), but direct the download directly to the DNS323 (i.e., not routed through the laptop) so that I can disconnect and expect that the download will complete without further involvement from me or my laptop.
Is there anyway to direct a download to a remote path? Any other suggestions for solving the problem?
