install the latest real-time kernal into my current Lucid 10.04 distro? I know I could download and use Ubuntu Studio, but 1.7Gb is too much for my monthly download allowance to handle, especially when all I need it for is to address the major latency issues I have with Audacity.
View 5 RepliesI 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:
mounting none on /dev failed No such device
It then takes me to the login screen, and once I enter my password it just takes me back to the login.
I am building a PC that dual boots Kubuntu and Windows and want to share the email store. Therefore, I would like to have real time or on access scanning of emails in an antivirus program like Windows does. I am not running an email server, just a desktop using pop3 and eventually imap email.
In previous Debian versions ClamAV and Dazuko used to do this. However, I understand that this setup doesn't work in Lucid. I tried p3scan but that hasn't been updated since 2008, once I managed to install it, it failed to find clamd even though it was running. I understand that clamdrib no longer works for Thunderbird 3. Amavisd as a replacement for p3scan, but this seems to be for mail servers.
I would be really grateful if anyone could tell me how to get on access/real time virus scanning of pop3 and imap emails on a desktop running Lucid with either Thunderbird 3 or Kmail, without having to buy an antivirus program like Avast Or point me to an existing tutorial that I might have missed.
As an aside (don't want much do I?) does anyone know if Kmail can be setup to only download the headers like Thunderbird does?
what the recommended way to set up real-time (or near real-time) folder synchronization among 2+ servers. I looked a rsync but that doesn't sound real-time and it looks like its something that you might put in a cron once an hour.

How can i convert this into the date/time of creation?
I am writing a shell script, which determines the OS installation date among other stuff, and i am assuming the root user's account creation date should be a pretty accurate pointer. Are there reasons why i should not be assuming so?I would be open to other suggestion for getting this date/time, but it would nevertheless be interesting to convert the unix time to "real" time without doing complex manual(or otherwise) computation..

Windows would open from the bottom and I could not click on anything cause when I tried,the mouse would jump to the side. Zoom slow and clunky. Mouse fireball always turned off. I'd uninstall and reinstall Compiz and that would fix it for about three days and then it's back to the same problems. I end up having to click no effects then click effects (middle button) and it looks for drivers,then I have to reactivate the mouse fireball. This happened every day,day in day out.

I have been using Lucid Lynx for almost 2 weeks and have got everything working, thanks to the "ubuntu" spirit in this forum. Now I am ready to upgrade my Wubi install to its separate partition. I have searched the forum and googled to find a way to do this, but I am still stuck.
I used lvpm (despite knowing that there is no confirmation of its working on Lucid Lynx), it didn't work. The installation happened alright but it wasn't able to show up the login screen (GDM?). It was stuck around the screen before that (Xsplash?).
There is this thread http://ubuntuforums.org/showthread.php?t=438591 that explains this process very well but remains silent on Lucid Lynx version.
I am sure there must be many other first timers who wanted to get their feet wet the easy way using wubi and would like to make it "permament" OS on their computers.
Is there anyone who can suggest if :
1. There is any way I can still use lvpm to transfer wubi install to separate installation (Ubuntu 10.04 release) ?
2. Any other way I can do this ??
I created filesystem XFS on partition hda8 with subvolume real-time on partition hda5: Code: mkfs.xfs -r rtdev=/dev/hda5 /dev/hda8 and i mounted it: Code: mount -t xfs -o rtdev=/dev/hda5 /dev/hda8 /xfs But I don't know how can I use this partition hda5 with subvolume real-time. I don't know how to create directories, copy files to it and another. Thanks for all answers!
EDIT:in manual it is writen: The realtime section is used to store the data of realtime files.These files had an attribute bit set through xfsctl(3) after file creation, before any data was written to the file.
I've got the following problem:
1. I start two bash windows
2. In one of them I start a script test1:
Code:
This script puts a natural number 5 times a second.
3. Then in the second bash window I type (as root):
Code:
The script test2 looks as follows:
Code:
While true; do
true;
done
During the following 15 seconds test2 is the process with the highest real-time priority. As far as I know the script doesn't perform any system calls so it shouldn't be suspended even for a minimal timeslice. My question is: why the process test1 manages to put a few numbers on the screen before test2 stops. I thought that test2 would exclusivly own the processor for 15 seconds.

I was wondering if there's a way for me to get real-time kernel support on regular Ubuntu 9.10 through some sort of update. I know Ubuntu Studio has a real-time kernel, but I'd prefer not to use it. I'm a fan of the original Ubuntu.
View 1 Replies View RelatedThought I'd put this together based on what I just did as it's hard to find a place where you get complete info in one place for this topic.
Not taking any credit as it's just piecing together stuff found on the net.
Of course this is for my specific hardware and system so YMMV:
- Palit Sonic GT 240 card
- Lucid 10.04.1 64-bit
- Intel DG33FB board and E7200 CPU
- LG monitor L194WT at 1440x900 res
Reason for choosing the latest NVidia drivers instead of the ones available from the System > Administration > Hardware Drivers option is that the latest ones contain specific fixes for my card, that are not available in the others.
Prerequisites:
All of the following is based on a freshly installed 64-bit Lucid 10.04.1 system. Some actions may need modification if you have already been tinkering with Nvidia drivers.
1. Backup your /etc/X11/xorg.conf file if any. The default clean install of 64-bit Lucid 10.04.1 doesn't create this file so unless you have generated and modified the xorg.conf file for your specific needs, skip this.
2. Install the following packages
Code:
If this doesn't work, run
Code:
And paste the output of that in the command above so you get, say
Code:
3. Remove the following packages using Synaptic's 'Completely Remove' option
- nvidia-173-modaliases
- nvidia-96-modaliases
- nvidia-current-modaliases
- nvidia-common
4. Create a new text file disable-nouveau.conf in the directory /etc/modprobe.d/ with the following contents
Code:
5. Download the latest NVidia drivers applicable to your card from here:[url]
6. Save the downloaded file (e.g. NVIDIA-Linux-x86_64-260.19.29.run in my case) to an easily accessible location like your home folder. Make this file executable by running, say
Code:
7. Check that the driver was correctly downloaded.
Code:
8. Run Update Manager, Check for updates and Apply any found
Installation:
1. Restart and choose the recovery option from the Grub options list.
2. Choose the Root Shell option in the list of options presented subsequently.
3. At the root shell run the following
Code:
If you skip this, the driver installer will inform you of the need to do this.
4. This will present you with a login prompt. Login with your admin username and password.
5. Navigate to the folder where the driver installer is present and run it, like
Code:
6. Accept the license text.
7. Say Yes to installing the 32-bit Open GL drivers.
8. I think you need to say Yes/ Accept once more time to initiate the driver installation.
9. Once the driver is installed it will ask you whether it should configure xorg.conf for you, say Yes. This will create the xorg.conf file if not present in your system and modify an existing one if present.
10. Back at the prompt, shutdown the system
Code:
11. Restart and use the normal startup option in the Grub options list, if all goes well you should see your beautiful desktop.
I have a linux router box with ubuntu which routes internet for several people. There is no extra traffic shaping, so everybody can get the whole bandwidth when its free. What I would like to have is a real time traffic counter per ip, just like a program called "iptraf" but on a per-ip basis. Iptraf can only count on a per-connection basis and thus cannot display a bandwidth that a certain ip has taken (because a single ip can start several onnections). So a console program with text interface like iptraf would be perfect - does anybody know about such a program? After some googling I came to the conclusion that such a program does not exist (which must be wrong - i think that per-ip real time traffic flow information is the first thing every router owner would like to know).
