I am using AT91SAM9260 and running Linux 2.6.27 on it. Once i sync the Kernel clock and cmos clock with the reference clock and leave it for 1 day, i see a drift of nearly 8-10 sec. The kernel clock is running faster. How can i correct this?
View 8 RepliesI have a Dell OptiPlex GX1 (CPU: Pentium II, 500Mhz). It's very old, and a while ago I installed an old version of Ubuntu on it. While it is switched on and booted up, everything is fine, however the trouble is when it is switched off, or just in BIOS.
The BIOS clock appears to be running at about 60x speed (eg minutes like seconds, hours like minutes). This happens both when switched off and when observing the clock from the BIOS menu. I really don't know what to do about this, and it's causing alot of problems, I've even had it get to the point where the system clock reset itself and would not recognise the OS as valid.
I'm using using ubuntu 11.04, and im using Avidemux (GTK+) whatever date that is, got it a couple days ago from the software center.
I attached some .a/s/s subtitles to the video, and the preview looked great. Encoded the video, and the audio plays like two times faster than the actual video, so by about halfway through the video, the audio is done and im left in silence with the video still going.
I set the video to MPEG-4 AVC, attach .a/s/s subs, leave audio alone, and encode using default option (Single pass-quality quantisizer)
Before the other day, I'd copied a live CD to ramdisk and run it from there before, but the disk was INX (INX is not X), a live CD based on Ubuntu that runs entirely in the text mode, no GUI. INX is a terrific product: colorful, educational, light, agile, fun to use, and and often damned useful, but when an OS only uses text, you may not notice how much running from the RAM speeds up an OS. Previously, I'd assumed that the best reason to run a Live CD from the RAM was to free up the CD ROM drive. When I started running a full KDE 3.5.10 Desktop from the RAM, it didn't take me long to notice the awesome boost in speed and performance.
The computer has the fastest access to the data that's in the RAM. (The "A" in "RAM" stands for "access", right?) So the machine is faster. As the RAM gets larger, I'm sure more and more live CDs are going to offer the RAMdisk option. Right now both INX and SLAX share the characteristic of being exceptionally small CDs, and that makes them well suited for this kind of application. The "minimal" version of Slax, the basic CD without any modules added, is less than 200 mbs, which fits very nicely on my 1024MB RAM. I now use the minimal SLAX cd to initiate the system, and I keep a collection of the modules on my hard drive to copy to the RAM and activate at will.
Here's a couple of screenshots: [URL] I'm using Wine here to run my one and only favorite Windows program, a text to speech program called READ PLEASE. Note that I am also running KTorrent, which is uploading from and downloading to my external MyBook hard drive. [URL]. Here's a shot of yakuake, which is sort of like Konsole with superpowers. I just upgraded my hard drive KDE system to 4.2.3, and they still haven't fixed Yakuake yet. I know it's been reported, so I'm sure it'll be taken care of.
Since kernel update 2.6.40 Totem plays video like in Fast Forward (no sound). Reverting to 2.6.38 solves the problem.

I am using FC 2.6.31 kernel and am tying to bring up a SDIO network card. I am not able to change the SDIO clock speed which is by default 50MHz.I have to bring it down to somewhere around 25Mhz to make the card working smooth.How can we set the host clock speed from our driver in this kernel.
View 1 Replies View RelatedI am trying to install vmware server on CentOS: In vmware installation guide it says before intalling:
Before you begin, read the following notes and make adjustments to your host system: The realtime clock function must be compiled in your Linux kernel. The parallel port PCstyle hardware option (CONFIG_PARPORT_PC) must be built and loaded as a kernel module (that is, it must be set to m when the kernel is compiled).
I just installed Moonlight but except for the clock that starts running, buffering and connecting to the video server nothing else works.The screen stays grey and there is no sound. I thought it might work when I install Java applet, but also that doesn't fix.
View 1 Replies View RelatedIn regards to compiling a custom kernel:
When using make menuconfig - under Device Drivers --> Character Devices --> there should be an option with the label "Enhanced Real Time Clock Support" (CONFIG_JS_RTC).
The problem is that this option seems to only show up while using the menu method when other options are either enabled or disabled and I've entirely forgotten what should be what. I swear fingered it out once.
This is on an older computer (P4) so HPET is no good.
You would think that disabling the HPET option would enable the RTC option but that does not appear to be the case.
I understand I can just add the option to the .config file and avoid this hassle but I'm very interested to know how to make this work.
To show my appreciation I will do something nice for you such as call you a nice name or tell you that you are pretty (or ugly if that's what you prefer).
I'm using a very simple conky script to diplay the date and time on my desktop. I've noticed that he conky clock is a few seconds early compared to the time displayed in the right hand side of the top panel (Natty). I guess both displays are based on the same "internal" time, so I'm left wondering how this could happen, and how to sync back the clocks.
It seems that Conky is in sync with the system date, while the panel clock is 2 seconds late (on my system). Checked with while true; do date; sleep 0.1; done
Just curious as to if it is possible to have the clock in the center of the task bar centered clock in Ubuntu 11.04?

How to build kernel modules
I have been trying to build linux from source code and run it from my machine (intel platform).
Here's what I did:
Code:
I am using Grub2. When I rebooted the new kernel was in the grub list all right. But booting from that kernel fails with no errors or warning. The screen just goes blank. The disk usage indicator LED also doesn't glow which I guess means that the kernel isn't being read from the disk. I rebooted using my older kernel and it booted properly. Then, when I listed my /boot directory, I noticed that there was no initrd.img for 2.6.39. kernel in there, which I think is the problem.
I've read about some sort of tools that help with kernel configuration.Can anyone tell me anything about these?It seems that you use the tool(s) on a running system. You use the running system for a while. The tool(s) gathers data and leaves bread crumbs. The tool(s) then process the bread crumbs to create a candidate config file for a fresh kernel build. The goal is a kernel build that contains parts you actually use and omits parts you don't use or don't need -- all the while using arcane knowledge of dependencies among various kernel features to (hopefully) avoid building a still-born kernel.

View 9 Replies View RelatedI'm looking to extract a config from a working kernel..that much was pretty easy..all ya gotta do is "cp /proc/config.gz ." which will put it in whatever directory you're currently in and then do a "gzip -d config.gz" to get the config file.
Now...after that it gets a bit tricky..Linus says you should never compile a kernel in /usr/src/ because those header files in ../include should never change. He says you should extract a new kernel gz in your home directory and compile it there. I tend to agree (who am I to argue?). Anyway..whereever your sources are this is where you need to copy the config file...
Like this...my home dir is "/home/dart". So I would put the kernel sources there under "/home/dart/linux". I would cd to /home/dart/linux and do "cp /proc/config.gz ." then "gzip -d config.gz" which should leave you with a file called "config", then "mv config .config"
Now here's where I run into a problem..when I do "make xconfig" I get this...

I have the latest release of Lucid Lynx installed. I want to try out audio recording on Linux so I want to know if it's possible to use a real time kernel with Lucid. So I installed the 2.6.31 real time kernel. It shows up in GRUB, but when I boot it gives me the message:

It then takes me to the login screen, and once I enter my password it just takes me back to the login.
