CentOS 5 :: Tclerror: Unknown Color Name "black"
Nov 5, 2009
I have just installed CentOS 5.4 and one of the applications I'm trying to run is PyMol - a molecular visualization tool - and when I start it I get a Python error that terminates with "Tclerror: unknown color name black" This particular application has two windows, a view window and a TCL/TK window that provides menus, and action buttons. The view window shows up but the Tcl/Tk window does not.
I have another application that gives a similar error: "tclerror: unknown color name grey90" This application does load and run, but it is a much more complex app that is likely only partially hindered. I haven't found yet how this one fails.
It seems to me that I don't have tcl/tk installed, configured, or enabled correctly, how to test this or how to troubleshoot the problems.

I have an HP color laser printer and I am looking for a way to print black as black instead of using tri-color. For example If I print a document that has colored text then any black text is printed using the color cartridges rather then using black. I have been surviving by using windows XP in virtualbox but I'm hoping someone can help me with this. I've looked all over then net for a solution but I've found nothing. I remember having similar problems like this with older Macs because of postscript printing and I'm thinking this is the same problem but I don't know how to fix it. I've searched the forums as well but no joy.

I tried posting this before and I'm not sure what happened but I don't think it worked, so if it did please forgive the double post.am very very new to centOS and linux in general. I just want to setup a test web server that more closely mirrors our actual web server that is hosted by rackspace. I've installed centOS and tried to setup Apache, PHP and MySQL from a guide on the web using Yum. When I go to localhost in the web browser I'm able to see the default apache page. However when I create a php page it's just blank.When I look at the apache error logs I get this: PHP Warning: Unknown: failed to open stream: Permission denied in Unknown on line 0
I've been searching alot on the internet and I know the issue is permission related, but I don't know how to fix it. I've seen some forum posts that say you need to use the chmod 775 command on the /var/www/html folder.Currently when I do ls -l /var/www/html it returns
-rw------- 1 root root 19 May 5 13:16 index.php
-rw------- 1 root root 19 May 5 13:15 index.php~
I'm sure that this isn't correct but like I said I don't know much about how to set permissions or who the owner needs to be. I've done alot of searching and seen similar posts, but no one seems to explain it clearly.

My Epson CX6000 works fine except it only prints in black whether I'm using image viewer, gimp, etc. It's been like this for some time, but I didn't need to print anything in color until now. I'm using Hardy Heron 8.04 and I didn't have any trouble installing the printer.

Dvds I make with DeVeDe play in color on my laptop (Ubuntu) but when played in my home theatre dvd player they only play in black and white. I have a feeling this is a codec issue?

I am trying to take a color photo and make it a high contrast black and white image. Just a 2 color image; rather, I just want the outline and nothing else.

I'm a little new to ubuntu. I installed a video driver and after restarting I got as far as the login screen where I saw that the driver did not work: screen is mostly black with random bars of color. I was only able to restart in recovery mode mode. I tried the fix graphics option, which did not work and also some commands that I've seen posted in other threads. So far, still cannot delete the problematic driver or boot up normally successfully.

I am using the screen app, and have set bce to on, and issued the following commands to set my background and foreground color: tput setab 4; clear; tput setaf 7; clear;
This temporarily sets everything properly on my screen. However, when I issue any commands that change or set their own background color (for example, when I issue an "ls" command with colorized output), the background color gets lost for any new output and I have to reissue the commands listed above in order to retrieve my background color.Ideally I'd like to keep my background color when issuing these commands, as it serves as a good way to remind me of what environment I am currently issuing commands in.

I am using comcast ISP with DHCP.
When I type in hostname -f it says unknown host
in /etc/sysconfig/network
hostname=servix.example.com
in /etc/hosts
127.0.0.1 servix.mydomain.com localhost localhost.localdomain
192.168.1.101 example.com www.example.com
in /etc/resolv.conf
search servix.mydomain.com
COMCAST SNS SERVERS
nameserver 192.168.1.1
In linksys router I have host as servix and domain as example.com. So why is it returning unknown host?

Im having a hanging problem with a HP dl160g6. uname -a shows:
Linux mail.xxxxx 2.6.18-194.3.1.el5 #1 SMP Thu May 13 13:08:30 EDT 2010 x86_64 x86_64 x86_64 GNU/Linux
The server was working fine since November �09 until a month or 2 ago.Sometimes (almost daily now) the machine hangs and shows the front "health led" blinking red.The services do not respond,locally i can see the login screen but when attempt to logon it freezes (the same happens with ssh).2 weeks ago i open a case in HP and the support sugest that the problem is in the X server (??), since then the system starts in runlevel 3 but the problem continues. A week ago open another case, on Tuesday make a BIOS upgrade but today in the morning the server hangs again.
There�s no strange messages in log files but... after the Tuesday hungs (before the upgrade) i can see the error msg below (thanks to the change to console mode):
Uhhuh. NMI received for unknown reason 30.Dazed and confused, but trying to continue.Do you have a strange power saving mode enabled?
Uhhuh. NMI received for unknown reason 20.Dazed and confused, but trying to continue.Do you have a strange power saving mode enabled?
adding "nohpet" as kernel parameter does not work.

when I try to send emails to new created emails account, I get this error:
<teste@topdapop.com>: Recipient address rejected: User unknown in virtual mailbox table�
And if I try to send a e-mail, the authentication fails if I setup the account at the desktop email client to password requirement on.
But it works when I try it using a webmail client (Horde) and I receive the email.The old emails accounts work fine. The new accounts and old ones were created with Plesk.I find an entry with
/usr/local/psa/admin/sbin/mail_auth_view | grep teste@topdapop.com
I get no output from
strings /var/spool/postfix/plesk/virtual.db | grep teste@topdapop.com
Using mchk and mailmng does not seems to change that.
I also found the file /etc/postfix/virtual.db .strings /etc/postfix/virtual.db : no output

we use for the installation of our machines bladelogic. We have different servers. Some servers have only one network interface, but it can be 2, 4 or may be more. There is always one network device for using PXE, but it is not always eth0.Is there any way to run kickstart without the entering of the PXE-Device so, that kickstart checks all the network devices in the system?

Unfortunately I've had no luck with using the default intel driver. It's strange really, you can see the gnome screen for a split second then it turns the display off like it's activating the external monitor or something. If I change the driver to vesa everything is fine.
Here is my info.

Getting this error seemingly randomly at login:
There was an error starting the GNOME Settings Daemon.
Some things, such as themes, sounds, or background settings may not work correctly.
The last error message was:
Launch helper exited with unknown return code 1
GNOME will still try to restart the Settings Daemon next time you log in.
I thought I might be logging in to fast, but it happened again when I had waited several minutes.

I have acquired what appears to be an old Gateway 2000 686 (Intel Chipset 82845G) with a Radeon X1600 graphics card and plan to turn it into a web server, although a minor problem, but I can not get a GUI (GNOME desktop) to load, however a text based server loads fine.Whether I use default 'GNOME Desktop' option at install or load text based install and use yum to install the GUI later, I get a couple of screen flickers and the screen goes black on start up.

I decided to give a try to VNC server on my remote dedicated centos machine. WHAT I DID:
yum groupinstall "X window system"
yum groupinstall "GNOME Desktop Environment"
yum install vnc-server
Followed the Centos wiki tutorial.
PROBLEM: After typing the password in my vnc viewer I get a black screen with cursor. I can move the cursor about but thats it.
SOLUTION: I have googled like crazy for the last 2 days but have not found a solution yet. My best guess is xorg.conf file, but I am quite new to linux so could be wrong.

I had VNC working with accounts that were logged in. Then I went thru the procedure for vnc-itsp-config (step 5 of the how-to-centos5 vnc server wiki) so that I could log in remotely to an account that was not already logged in.
All went well until....I tried to log in and all I get is this X11 window with a X cursor and a black screen.
I have restarted the vncserver service but I suspect it is a x11 issue (just a guess).
