Hello everyone, I just installed the CentOS 6.8 updates from the CR repository, and then I rebooted the server. I run some software to make weather images on a website, and I have run into a problem. When I do it, the software, as it tries to plot the image, says: Xwindow: unable to connect to display It just stopped working when I did the updates. Has anyone else seen this, or have an idea on

Hi Friends, I am trying to run vnc on port 8080 on Centos 3.4 . There are no kde or gdm packages installed as we only need xserver. I have installed XFree86-font-utils-4.3.0-78.EL XFree86-75dpi-fonts-4.3.0-78.EL XFree86-base-fonts-4.3.0-78.EL XFree86-xdm-4.3.0-78.EL XFree86-libs-data-4.3.0-78.EL XFree86-4.3.0-78.EL XFree86-libs-4.3.0-78.EL XFree86-xfs-4.3.0-78.EL XFree86-Mesa-libGL-4.3.0-78.EL

...r not switch to something like X2Go as I wasn't too keen on it when I last tried it. I have done plenty of research on the web that describes how to do this, but I must be missing something. I have the following things configured on the CentOS 6 box. /etc/gdm/custom.conf file [security] DisallowTCP=false AllowRemoteRoot=true [xdmcp] Enable=true /etc/ssh/sshd_config X11Forwarding yes X11DisplayOffset 10 X11UseLocalHost yes I start Xming on the Win7 box with the basic parameters.

...tual frame buffers (Xvfb). When I do xhost + > servername , it says it has been added to the control list...but it still > doesn't fix the issue. Does anyone know what I may be doing wrong? Also, doing an "xhost +" does not help, either, and in /etc/gdm/custom.conf, I have: DisallowTCP=false Any ideas would be greatly appreciated. Thank you!

I've encountered a strange problem in CentOS 4.1. I've never had this problem before, and I've been using X Windows since 1990, but I can't get remote X connections to work: $ hostname host00 $ echo $DISPLAY :0.0 $ xhost + access control disabled, clients can connect from any host $ rsh host01 $ xdpyinfo -d host00:0.0 xdpyinfo: unable to open display

...nest like this: > ssh -X -C -l $LOGINUSER $HOST -n "Xnest :1 -ac -geometry 1440x850 > -once -query localhost I get a black screen without any login window or desktop background. My /etc/gdm/custom.conf looks like this: > # GDM configuration storage > [daemon] > [security] > DisallowTCP=false > AllowRemoteRoot=true > [xdmcp] > Enable=true > [greeter] > IncludeAll=true > [chooser] > [debug] According to the howtos on the net this should be sufficient, so I am quite stuck. How can I figure out if this is a problem of the CentOS config or of XQuartz? Any hint...

Hello list, In the past we have instructed users to perform 'xhost +' from their centos desktop, then set the DISPLAY variable on a remote computer to forward their display back to the desktop. This does not seem to work on centos 6 - but it did work in centos 5. It works from a vnc session on the desktop machine, but does not work from the local desktop. We would typically use a display

i''ve managed to get 2009.06 installed in a Xen DomU on Linux Dom0. it''s currently ''up'' with a static IP, and i can successfully ssh into the box as either root or ''myuser''. all network/login settings seem to survive reboot. i''ve set up for VNC to the DomU. i can connect, and am at the Gnome login window. but, neither

An intermittent need to connect to a CentOS4 development box from a MS-Win2K workstation using X-Windows has developed here. However, I cannot seem to find a cheap (read free) X-windows client for MS- Windows to accommodate this. This seems very odd to me, displaying no doubt my profound ignorance of the issues involved. The few shareware versions that I have located expect registration

In CentOS5 you were able to create a server section in /etc/gdm/custom.conf such as [server-Standard] name=Standard server command=/usr/bin/Xorg -br -audit 4 -s 15 chooser=false handled=true flexible=true priority=0 After this change, Xorg would run with the -br -audit 4 -s 15 options. Unfortunately in CentOS6 this is not the case. It completely ignores anything put into custom.conf as far

Hi All, I followed the instructions here at http://bderzhavets.wordpress.com/2009/06/10/setup-fedora-11-pv-domu-at-xen-3-4-1-dom0-kernel-2-6-30-rc6-tip-on-top-of-fedora-11/ However, when I do a "make menuconfig", I cannot see any XEN related configuration options. What am I missing? Thank you. Mr. Teo En Ming Dip(Mechatronics Engineering) BEng(Hons)(Mechanical Engineering)
