Network Servers window kills all Nautilus windows in CentOS 5.1?
by MHR 07 Dec '07

07 Dec '07

In the process of doing something else, I happened to open the Network Servers window from the Places applet menu. When I did, it killed all my Nautilus windows on all my workspaces. (I had to experiment a little to prove this, but it did happen.) Is there an explanation for this and what? Thanks. mhr

I ran into this when I first put Linux on my laptop back in the summer of 2005. I originally worked around it by just attaching an external monitor which also works but takes a little more planning and effort. The problem probably has something to do with anaconda shifting into graphics mode when anaconda starts but the mode isn't compatible with the laptop's LCD display. Using nofb tells the kernel not to use frame buffers which keeps the install in a standard (e.g., VGA) mode or the external monitor works with the display mode. Cheers, Dave -- Politics, n.

RHEL 5 vs. CentOS 5
by Lopez, Denise 06 Dec '07

06 Dec '07

Hi all, I would like to first preface this e-mail by saying if this topic has been covered already, could someone point me to the month of the discussion and I will gladly read it. We have been using RHEL 3 / 4 in our environment and I am very happy and satisfied with the stability of the OS. Now with the new technologies incorporated into RHEL5, specifically Virtualization, Clustering, and Storage, and the costs associated with them, I was wondering how similar CentOS and RHEL 5 were. It is my understanding that CentOS is RHEL 5 with the RedHat icons removed but the functionality of the packages is the same. In addition, updates may come a day or two later than RHEL 5. My boss is a little concerned about the differences since we host production servers that require minimal downtime. Any thoughts and opinions are very welcome. Thank you for your input.

Updating kernel from CentOS 5 to 5.1
by Andrew Allen 06 Dec '07

06 Dec '07

To upgrade the kernel to CentOS 5.1 (to take advantage of support for Dell wireless card bcm43xx), should I update everything or just type 'yum update kernel', or what? Also, is it OK to remove 'old' kernels (which appear in the boot list) when they are no longer required? Thanks, Andy

RPM Spec and subpackage architecture
by Ross S. W. Walker 06 Dec '07

06 Dec '07

Are there any RPM wizards out there that know how to specify a different architecture for a subpackage in a spec file? I have a package that has a binary component and a non-binary component that I would like split into 2 packages one, the binary which is architecture dependant and the other 'noarch'. I haven't found a spec file that does this yet :-( Ross S. W.
