I recently loaded ubuntu 10.04 on an older laptop to get a feel for using a GUI version. I would like to setup a recurring job schedule to start sound recorder or Audacity. I would prefer it was from a graphical user interface but would do it with a cron if I could get started.

I'm trying to run a command with the 'at' scheduler in Linux Mint 9. It's basically a ssh connection to my Smoothwall firewall to tell it to shut down, but that part isn't really important. The problem I have is that I can't get the 'at' schedule command to do much. I can type commands into the terminal and they work perfectly. If I enter exactly the same command into 'at' nothing happens.
For example, I can type 'plink -load smoothwall' into a terminal and a new ssh terminal comes up asking for my password to make an ssh connection. If I create an 'at' job with the same command, ie:
Code:
$ at now + 5 minutes
at> plink -load smoothwall
at> <Ctrl-d>
$
then nothing at all happens when the 5 minutes are up. I've checked that the job exists by doing an 'atq' command. Obviously there's something about 'at' that I don't understand. I've googled, I've looked in this forum and I've looked in a copy of 'The Linux Bible 2010' all without success. I've tried various alternative ways of entering the command for a couple of hours and I'm still stuck.
I am new to the forum and new to Linux.
I am trying to explore if Linux can be run on a multicore platform when the max frequency of one the cores is less than the others.
please give me some pointers or let me know if you have tried such HW configuration.

as we all know Process Scheduler does Process scheduling and its a process as well. I was just wondering that if this happens then the Process "Process Scheduler" should be a part of Process queue as well.
So if there are 5 process are there in Process queue & process scheduler is administrating them then since its also a process, once it puts a process under RUN state it should itself go inside queue because at one instant only one process can get executed on a processor. This is quite confusing for me. Please help me out. I tried to search on this but could not find any relevant topics.
I recently got an SSD and want to switch to using the noop IO scheduler permanently. I understand how to change the scheduler at runtime, but where can I put the command to make it apply on bootup?
I know you can pass "elevator=noop" to the kernel, but that sets all the drives to that scheduler, which I don't want as I still have ye olde spinning drives too - I just want a single drive set to noop..
I'm guessing there's an init script somewhere which is ideal for this, but I've no clue which!

When I try to schedule a task with kcron, It doesnt work. I installed it with sudo apt-get install kcron. Now it appears in advanced system settings.If I test the task with the run now button the task works correctly. However, when the set time arrives, the task is not performed automatically. I have tried both the personal user cron and the system cron.
By the way, when I try sudo service crond restart, It says service not recognized and when I use sudo contab -e, the file is empty. It should have something since I added an entry in the system's cron in the kde schedule manager.

I checked and doubled-checked the lsmod | head to make sure that my drivers (sisfb / sis_drv.so) were installed and loaded. they were. I then made sure that my pc was opengl-supporting (Glxinfo | grep "direct rendering". The answer was positive. With that in mind, I tried many different ways to run compiz(compiz --replace, appearance-desktop effect, run app-compiz) but neither if these gave any results.
View 1 Replies View RelatedI'm having a problem with Vuze locking up when I use the speed scheduler plugin. I never had this issue when I was using them in windows.
Here is whats happening. I have speed scheduler set to pause my seeds during the day. sometimes when it pauses a finished torrent the status of the torrent will be stuck on "stopping". When it does this my bandwidth up and down drop to 0 and I cannot download new torrents. I cannot removed the "stopping" torrent or even restart it. Vuze just kind of locks up. I have to kill the java process and restart Vuse before I can get it working again.
I'm running the latest version of Vuze and the speed scheduler plugin on Ubuntu 10.04.

Following VMware recommendations on how to change linux I/O scheduler for guests, I'm trying to do it on my VM machine running Debian Wheezy. At the moment I'm running kernel backports:
Code: Select all$ uname -a
Linux brutus2 3.16.0-0.bpo.4-amd64 #1 SMP Debian 3.16.7-ckt20-1+deb8u3~bpo70+1 (2016-01-19) x86_64 GNU/Linux
The default I/O scheduler at the moment for device /dev/sda is CFQ, and I can change it on the fly to NOOP:
Code: Select all$ cat /sys/block/sda/queue/scheduler
noop deadline [cfq]
$ echo noop > /sys/block/sda/queue/scheduler
$ cat /sys/block/sda/queue/scheduler
[noop] deadline cfq

View 3 Replies View RelatedI recently read about "at" and thought it was neat, so I wanted to try it out. Unfortunately, it doesn't seem to do what it's supposed to. I would type: at now + 1 min
Then in the prompt I would type:
echo hello
zenity --info --text="HELLO"
<Ctrl+D>
I confirm the job is entered with "atq" and sure enough, the job is there, for the correct time. When the time comes around, nothing happens, and the job disappears. I don't see any text in the console, nor do I see a zenity infobox pop up.
We've got an old pentium computer dual booting Ubuntu and Windows XP. We've purchased a PNY GeForce FX 5200 256MB 128-bit DDR PCI Video Card for it. After installing it, we had full access to the XP and installing drivers from there went without a hitch and appears to work fine. When we tried to boot into Ubuntu, all we got was the (initramfs) prompt, and we're both relatively new to the fantastic world of Linux and so we have no idea what to do with it and finding information concerning our issue has been fruitless, as we can't seem to find anyone that has had a similiar problem.
We then uninstalled the card, booted up Ubuntu and tried to install drivers via administration>Hardware Drivers, but the computer doesn't appear to have any on board graphics, and so Ubuntu won't allow us to use any of the drivers in the hardware drivers (via administration). We then did a tonne of research and followed a few tutorials for installing Unix drivers from the Nvidia web site.
One of the tutorials that we followed involved doing a Control+Alt+F1 and then shutting down the GDM to install the new drivers. After installing the new drivers, we for what ever reason, couldn't restart the GDM. After what appears to be a failed attempt at installing the driver, we cannot access the desktop and are now presented with the following message (when booting in normal kernel mode): "Ubuntu is running in low-graphics mode. The following error was encountered. You may need to update your configuration to solve this. (EE) No devices detected.". The only 4 options are:
#1)Run Ubuntu in low-graphics mode for just one session. This results in a black screen without a prompt, Control+Alt+F1 gets us a prompt in the top left of the screen that isn't flashing and we can't do anything at all.
#2)Reconfigure graphics. This gives us three options of which we have no idea what to do with:
1) Use default (generic) configuration,
2) Create new configuration for this hardware,
3) Use your backed-up configuration, along with the OK and Cancel option, which, the latter option takes us back to the original 4 options.
#3)Troubleshoot the error. There are four options here:
1)Review the xserver log file (no idea what to do with this),
2)Review the startup errors (no idea what to do with this),
3)Edit configuration file (no idea what to do with this),
4)Archive configuration and logs (which has been done).
#4)Exit to console login. (gets us a prompt in the top left of the screen that isn't flashing and we can't do anything at all). We are in dire need of some guidance, before attempting any of the options in "Reconfigure graphics" , as we have no idea what to do with any of it and recovery mode doesn't get us anywhere either.
I am running a Gateway MX6121 laptop with Ubuntu 11.04.I had Screenlets installed under 10.10, did a complete removal and installation of the latest version.The screenlet manager opens, and there is an indicator applet, but I cannot add any screenlets to the desktop. When I double-click on a screenlet, the screen flashes like it is trying to add to the desktop, but nothing happens.
View 2 Replies View RelatedI the Linux kernel 2.6.32, The CFQ scheduler has been changed as you probably know. They insert the 'low_latency" mode in it.I read that this option, actually limits the affect of the dirty data write from the buffer cache while the system doing sync IO.
From url:
Quote:
"the amount of async writeback sent to the device will be limited by the time since that last sync IO." "limiting the damage that the async IO can do while sync IO is also happening"
I also read that this option is not recommended to Database server.As I know, DB writes his DB files with O_DIRECT and won't write to the Filesustem buffer cache.SO this option don't need do bother him.

View 3 Replies View RelatedFor the past few weeks my system has been exhibiting some strange behavior. The first of these instances has been in the form of a total system lockup necessitating a power cycle -- ie. no kernel panic or oops, but cessation of all on-screen activity and an unresponsive mouse and keyboard. ( The first lockup occurred when the monitor was powered down)
Just a few days ago, I started noticing something else : Launching Firefox (3.6.4pre) resulted in it locking up near start-up especially if I was logged into Gmail. After that I experienced a total system lockup and then another one which has placed me in the situation as suggested in the title.
Specifically, KDM and the KDM login manager will start-up and I will be allowed to type my password. Immediately after that when the first of the icons in the KDE start-up animation starts to come into focus the screen goes black and I am returned to the KDM login manager -- I can enter my password again and continue this process ad infinitum.
Trying to diagnose the issue, I attached GDB to KDM. It seems that after I enter my password one or more of the KDE start-up processes dies with signal 1 or to be more specific :
Code:
Program received signal SIGUSR1, User defined signal 1.
0x00007f4ae742d3c3 in select () from /lib/libc.so.6
