Fedora :: Any Way To Set Visualization As Wallpaper?

View 2 Replies View RelatedHardware :: Suspend / Wake And CPU Visualization
Jun 18, 2010Here is the latest in my saga of me vs. Suspend in Utuntu.
Dell Studio XPS 8000 desktop
i7-860 CPU
8 GB RAM
swap area set to 9 GB (because I was experimenting with hibernate)
nVIdia GeForce GT220 1 GB
Ubuntu 10.04 64 bit, all patches, nVidia-current 195.36.24
So I was poking around in BIOS and looking at CPU Features. I have also a problem with my VMWare machines sucking up a core or 2 at 100% after suspending and waking the host. Just for the halibut I Disabled CPU Visualization. My VMWare XP guest now starts up a lot faster! (?) and I have discovered. If I do a suspend of the host BEFORE starting and LOGGING IN to a VM it seems to work great. I can wake the host and am presented with the locked screen dialog asking for my password. I have done about 20 suspend/wakes with no problems. So far, so good.
Upon further testing I find that I can start a VMWare or Virtualbox XP guest machine and still suspend/wake - at least so far with a limited number of tries. Most importantly, if I log into the guest (VMWare or Virtualbox) I find that suspend/wake fails 100% of the time. By fail I mean that the host suspends but when I attempt to wake it I find that I am logged out of the host and all programs which were running at suspend time are no longer running. Firefox restores the previous session indicating that it was shut down incorrectly or unexpectedly.

- When we use umask (022) command in terminal. and create a new file then the permissions applied for new file is for that session and when the system will reboot linux will take automatically its default permission from etc/bashrc or /etc/profile ?
- Can we make our own umask or the professional way is to follow 022 only ?

Ubuntu Multimedia :: Music Visualizer With Beat Visualization
May 3, 2010I am looking for a beat visualizer (for lack of a better word) to use full screen when playing music on my computer. What do I mean by that? I know there are a lot of visualizers out there that create colored swirls and spectrum analyzers and stuff based on the waveform of the music being played (e.g. Goom). But they do not really visualize the music to any great extent. If you play Mozart or if you play Chemical Brothers it does not do all that much of a difference visually.
What I want is a visualizer that reflects the music to some degree, and in particular the main beat. If there is a strong thumping beat I want that to be reflected on the screen at the same time as the beat plays through the speaker. Here is a simple example illustrating what I mean (forward to 1:00): [URL]
Please note that it is not the simplicity in the video I am looking for, it was just that this video did well in illustrating the main principle. If possible I would like to have swirls and smooth animations also (like Goom) but the most important thing is that it should reflect the music in a more direct way and be perfectly synchronized with the beat.

Jan 1, 2010I have two servers, both running CentOS, but one running Cpanel as the control panel and the other running Webmin.
I would like to sync the web folders using rsync. However, when I sync the files from the Cpanel host the permissions look as follows:

But that doesn't work on the Webmin server which needs the following:
Code:
It seems the Cpanel install has the group as 'nobody' whilst webmin has it the same as the file owner. I can fix this by running:

But as the file transfers will be frequent, I don't want the files to be inaccessible until chown is run.
So, what I really want to know is - how can I change things on the 'webmin' server so that files with ownership owner:nobody will run?

CentOS 5 :: Booting CentOS V5.2 Fails With GRUB Error 13: Invalid Executable Format?
May 5, 2009I'm trying to install a dual booting machine with OpenSUSE v11.1 32bit and CentOS v5.2 64bit. I installed OpenSUSE first and allowed it to install and configure grub in the MBR and after that I wanted to proceed with CentOS v5.2. The installation went fine with two notable exceptions:- when I had to configure grub installation parameters, CentOS offered me only 2 solutions: either install it on the MBR of the first hard disk or not installing it at all. Other distributions are more flexible allowing you to install it in the boot sector of the root partition for example. Because I didn't want to ruin the existent grub onfiguration, I reluctantly accepted not to install it for CentOS assuming that I could manually configure the entry later in grub's menu.lst file.
- when I was presented with the options for software components installation, I've clicked on virtualization category/function because I intend to use the machine as a VMware host. There was no guidance on screen at that point and I blindly assumed that by choosing the virtualization function I would get necessary tools and drivers that will help me further on. It seems that this was a wrong move as you can see it below.
After completing the installation, I tried to search for a template or guiding on how the menu entry in menu.lst should look like but the grub directory was empty, not surprisingly because I've told CentOS earlier not to install it. Using the files in the /boot directory from the CentOS installation I tried to improvise a menu entry but it's not working. The boot stops with famous Error 13: Invalid or unsupported executable format. Using the file command to check what kind of files I'm trying to load as kernels I'm getting :

CentOS 5 :: Kernel Panic Not Syncing No Init After Fresh Install Centos 5.3 Iscsi?
Jul 9, 2009The first server I installed installed fine. The second server, installed with the same config, went to "kernel panic not syncing no init found try passing init= option in kernel" error. I tried reinstalling but it keeps going to that error after install reboot. The storage is ISCSI connected via Intel Server Adapter, which allows it to boot from ISCSI. Not sure if that's the cause for the problem, but the first server is connected to the same ISCSI and installed just fine.
Is there a way that I can make sure ISCSI module installs during installation? Although I think it is installed since it's able to copy the files and setup /dev/sda. I just wana make sure that it installs during setup.
CentOS 5 :: Create A CentOS Based LiveCD That Mounts A NFS Share And Executes One Script?
Aug 14, 2009I'm trying to create a CentOS based liveCD that mounts a NFS share and executes one script there. The NFS never mounts altough while logged I can mount it with the very same command that I use in the KS.
In the %post I have :
%post --log=/tmp/post.log --erroronfail
mkdir /mnt/nfs
mount -o nolock 10.23.1.1:/csc/RemoteHome /mnt/nfs
I added the --log in order to debug, but nothing is written in /tmp/post.log. I tried redirection on the mount command with >> /tmp/debug.log but this is not written. Maybe during the post sequence /tmp is RO ? Anyway, I tried with ifup lo, service portmap start in the %post, but doesnt change (I even have a service : command not found in the live cd creator output).

View 11 Replies View RelatedCentOS 5 :: CentOS 5 Home Server Power Consumtion? (features, Kernel Versions Etc.)?
Feb 28, 2010I built a home server (NAS/WWW/SSH/media server etc) and chose CentOS 5 as the OS (stability, easy of configuration).I was just about to start tuning the power consumption when I realised that the kernel CentOS uses is so "old" that it does not support the latest reduced power consumption enhancements that Linux has achieved in big strides in the recent past (we are probably still talking 6-12+ months ago e.g. tickless kernel)..
So my questions; 1) I know CentOS was maybe not meant for home servers (certainly its not its primary purpose), but if it is, any ideas of what kind of power consumption it takes (I know its relative) and if there are particular power consumptions that are worthwhile?
2) Do you recommend me compiling my own 2.6.21+ kernel from kernel.org or am I just likely to have compatibility issues (I really did not want to do that) or when is CentOS 5.4 supposed to have a newer 2.6.21+ version kernel?
Was it wrong of me in principle to choose CentOS for a home server when I am power conscious? (I don't have a low-power VIA processor either but a P4 so I am really just hoping to make do with software changes).
CentOS 5 Server :: Building VMWare Virtual Machines From CentOS Mail Servers?
Oct 12, 2010I have a few mail servers, a mail log server and a web server running on Centos 5. Now I have a task: to avoid accidental crashes on the production servers while installing updates, my boss asked me to do clones (these clones will all be VMware virtual machines) of the servers (EXCLUDING the actual e-mails and log contents) and then to run those clones on VMWare Server. This way, first I will install and test updates on the clones and - if they will be running without crashes - I will apply the updates on the real production servers themselves.
I have already installed VMWare Server 2.0 I have a few questions: How do I build the virtual machines to exclude the actual mail files and mail logs? Can I use VMware Converter for this purpose, or do I have to use another program? How do I actually do this cloning? Is there a tutorial on how to do this?
CentOS 5 Networking :: Centos 5.2 / Hyper-V/ Bridge With Synthetic Adapters Does Not Work?
Jan 27, 2009I have a Centos 5.2 VM running under Windows 2008 Hyper-V. If I add two "legacy Nic's" and bridge them, everything appears to work fine. However, if I remove the legacy nics and replace them with two synthetic nics (linux integration components), the nics seems to function fine UNTIL I add them to a bridge.This VM will eventually be used as a DansGuardian/Squid transparent proxy for a local library. The logical layout is represented by the attached jpg image. I have also included the ifcfg- scripts for the adapters and bridge for both scenarios.It would also be useful if someone else has Hyper-V with the integration components and dual physical nics to see if they can reproduce my symptoms on their box.Legacy Adapters:
