Changing Color Mappings
by Brian Becker 18 Mar '09

18 Mar '09

I have been tasked with finding a way to change the color mappings on a CentOS 5.2 system. Basically I want to make an image that is black and white appear in different shades of gray by adjusting the color mappings. I need to know the starting point for the color maps however so I can make the appropriate adjustments. I have been told this should be some kind of look up table array of 256x3 elements. I have searched through the frame buffer in the kernel and the driver area for the intel frame buffer but haven't found anything that looks appropriate. Does this table exist or is the problem being tackled completely wrong. Any help, ideas, or pointers would be greatly appreciated. Thanks in advance. Brian

How to get usb storage under /media in runlevel 3?
by Kimmo Koivisto 18 Mar '09

18 Mar '09

Hello I have previously used Centos 4.x in runlevel 3, when I plug in my usb storage device/cd in cd-rom, it is shown under /media, for example /media/MyUsbStick. Now in Centos 5.2, when I insert usb storage device, nothing is shown under /media (runlevel 3). When I have runlevel 5 and X running, usb stick / cdrom is automounted fine. I can mount the stick using /dev/xxx device, but would prefer if: a) cdrom and usb-stick would appear under /media automatically and I could manually mount it b) cdrom and usb-stick would be automounted when inserted (like in runlevel 5). Any ideas, how to accomplish (a) or (b)? Regards, Kimmo Koivisto

Correct way to provide kernel patch
by Chris Miller 18 Mar '09

18 Mar '09

I work with a USB device that is intercepted by the USB HID driver. In order to stop this behavior, the device needs to be added to the HID blacklist (hid-core.c) and a custom kernel needs to be compiled. If I create a CentOS specific patch, it appears I need to create the patch against an already patched source tree (i.e. after running rpmbuild -bp) because other patches exist that add items to the blacklist that would break my diff patch. Seems like this would be a never ending battle as new patches get added to new kernels. What's the correct way to get this device added to the kernel? Do I submit my patch to the CentOS dev team, to the kernel.org folks, or both? What's the timeline (if accepted) to actually seeing this in a production kernel? On the CentOS kernel build how-to, the kABI fixes won't make it into CentOS until 5.4, and 5.3 hasn't been released yet. Thanks in advance... Regards, Chris

Streaming video with Centos 5.2...how to?
by Gilbert Sebenste 18 Mar '09

18 Mar '09

Hello all, I am a noob to streaming video, and I have a file I'd like to stream (a .wmv file...sorry. ;-) ). In any case, how can I do this on my website using Centos 5.2 and Apache 2.2.8, rather than making people download a 20 MB video? Can someone point me to some URL's and some software? Thanks for any help, I greatly appreciate it!

Centos 5.2 live cd won't boot
by tblader 18 Mar '09

18 Mar '09

Hello All Anyone have a workaround for booting the 5.2 LiveCD? I'm getting this error: no root yet, udev rule will write symlink Then I drop to a shell, with a message to create a symlink to /dev/root and then exit the shell. There is also a message that it cannot find the root filesystem. Is there a way to disable udev with grub? Thanks

Cheers. It is this time of year again: CentOS is going to Linuxtag 2009 (well, at least we will try to get a booth there). If you want to be part of the team there, stay tuned for news here in centos-promo(a)centos.org. Deadline for the projects is 24th of march (short call!), I will try to apply sooner than that >:) Cheers and thanks, Ralph

The grub.conf file provided has root set to drive hd2 and partition 0. It appears that something changed the order of your drive numbering (e.g. you moved the cable that attached you boot drive from IDE1 to IDE0 when you installed the new CPU).
