Hello everyone, Since I upgraded to CentOS 6.8 last week, I am having an issue whereby I log out, and then it attempts to log me in as the same user. I then click on another user and try to log in, but it instantly blows me right out and back to the login prompt for the original user. I do have GDM set up to auto-login at boot to a particular user in /etc/gdm/custom.conf, but it has always

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

The rgl package currently crashes R when running under Xvfb (the "virtual frame buffer" server), at least on MacOSX. It makes sense that it shouldn't be able to work there (it needs interactivity), but I don't know how to detect the problems before they cause the crash. Currently the error happens the first time you try to open an rgl window; when rgl calls XCreateWindow R

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

I now have it so that it prints a few pages, then locks up the printer. Funny, it worked just fine under CentOS5, now under CentOS 6, it won't? That's weird. Do you, or anyone else, have any

Hello everyone, A quick Gnome question that has vexed me. In CentOS 5.10, if I have, say, an X terminal window up on my screen, the next time I log in, it's there when I log in as an unprivileged user. That's because I can save the layout the way I want to; there's a checkbox for it to save the layout upon exiting. I see none for CentOS 6.5. So, my X-terminal isn't there when I

Hello everyone, I have been scouring the Internet for answers, wikipages, non-Centos pages, and I am stumped. I have a HP LaserJet P4014n. When I plugged it in via USB cable, it found it as a P4014, but in any case, it simply wouldn't print, so I deleted it, and tried to start from scratch. When I manually add the printer, it seems all is well, but it won't print a test page. In my

Hello everyone, A network engineer buddy of mine brought up for discussion with me that he'd like to do some throughput testing, but he's new to Linux/RedHat. Is there any software I can recommend to him that any of you find above par for CentOS 6/7? Thanks!

Hello everyone, When I type "sa-update" to get the latest files for Spamassassin, I see this error: ]# sa-update Argument "1.39_01" isn't numeric in subroutine entry at /usr/bin/sa-update line 83. My Google-fu came up with nothing when searching for this error. Am I the only one getting this to happen, or are any of you seeing it as well? Gilbert

Hello all, Several days ago, I noticed Firefox 3.0.8 was released for i386, but I haven't seen it on any of the mirrors. I know it can take a few days for mirrors to sync, but I think it's been 5 days now. Anyone see this package out there yet? ******************************************************************************* Gilbert Sebenste

Hello everyone, Maybe this doesn't make sense, but after I updated autofs yesterday and rebooted this morning, X windows won't go. It tries with the old configuration---doesn't work. It tries a fresh config and fails. I can't copy and paste, but it says screens found, but no usable configuration. Couldn't start X server on card 0 Couldn't start X server with old

Karanbir, No one should ever have to go through that. I am sorry to hear that someone has done that evil deed to you. May they be forgiven, but know the pain that they have caused you and repent of their sins. And if there's something I can do to help, please let me know. ******************************************************************************* Gilbert Sebenste
