Ubuntu :: Launch Script At Startup After Specific Time?
Jun 13, 2011
I'm running Ubuntu 10.10 in a computer with a 7200rpm HD, 8Gb Ram, and a Core i7, and the time it takes to load the desktop is insane. There are threads that mention the problem of gnome looking for nonexistent floppy drives and to solve the problem by disabling that in the BIOS (option I don't have). Anyway, besides that problem, by running at startup a gnome-terminal with the iotop command, I noticed that two processes have a huge i/o load on the system: google desktop and ubuntu one. I would like those programs to run as part of the startup process, but be launched after several seconds (to allow the rest of the programs to load). Is there any way I can achieve this? I think there should be a way modifying the commands under startup application, but I cannot find anything that works.

I want to record an internet radio station starting at 2:00am tomorrow morning. The specific program on the radio station lasts until 6:00am. The command I need to run to record the station is: Code:mplayer http://wjcu.jcu.edu:8001/listen.pls -ao pcm:file=indie_heat_of_the_night.wav -vc dummy -vo nullI'd use cron, but 1. I'm not sure how to and 2. it seems unnecessarily complicated for something that I only want to run once. If cron is the only/easiest solution, I guess I'll just have to resort to that, but I'd rather not.

I need to creat launcher that launches Terminal into a specific Profile..
I found a website that says that this code will work
Code:
gnome-terminal --window-with-profile=<Profile_name>
But, I also need to launch to specific Directory also. So, My code looks like this
Code:
gnome-terminal --window-with-profile=Scripts --working-directory /home/mike2/Desktop/Scripts
But it doesnt work.. I have a feeling I'm doing something wrong, though.

I can't remember the name of the GUI app that I used that allowed me to specify which workspace specific apps would launch in when I start up my computer.

I have a laptop running Ubuntu hooked up to a TV via a VGA to S-Video converter with the VGA-out through an external monitor, and I am trying to find a way to set vlc or mplayer to open fullscreen in the external monitor by default. Eventually I want to be able to hit enter on a video file and have it play on the TV without any dragging to the external monitor. I have googled around a bit, checked the monitor settings options, and looked through the media player options but so far can't find anything.

My wish is to launch some programs (chromium, pidgin and xchat on the first virtual desktop and the terminal, the file manager and geany on the second one). I also wish them to have the same size and place than they've had the last time I used them (just to keep them always at the same place). My researches haven't been successful for the moment cause the only idea I found was lxsession-edit which doesn't do exactly what I want..

I have downloaded Ubuntu within windows 7, with wubi. It shows itself as Ubuntu 10.10, though I had selected 11.04, not to worry, this is for information only. I downloaded Q Cad, a drawing programme from the Ubuntu software centre and it shows in the list but I do not know how to launch it.I will have to down load some more applications and I think I will run into this wall again. I can enter CLI through Ctrl+Alt+F1 to F7 and probably do nothing more.

How can I turn off specific authentications? I don't want to have to authenticate every time I mount a different drive (in a different partition). (Because I can't open Mozilla, since it pulls a profile from that partition, without authenticating; and I want to have Mozilla automatically launch on startup, but it can't launch if I need to type my password to gain access to the drive first!).

I have both ubuntu and kde-desktop installed, and after trying KDM, switched back to GDM which worked fine for a while (although KDE changed my other gnome settings like usplash and cursors which took a while to change back). A day later, though, when I start up my system, the screen flickers a few times then shows me a message that an x-server is already running, so hit no to try loading it on '0' again or yes to try another number.
If I hit no, it will briefly show me the KDE login screen refresh a few times and go back to the menu. If I hit yes, it refreshes about 7 times and finally shows the gnome login screen. This process takes a long time and I'm not sure is great for my screen.

So at work I usually forget to shut down my computer at the end of the day 5:30 and they switch the breaker off at 6pm which cant be good way to shut down a computer. So i was doing some googling and this is what i come up with.

How do you find a file modified March 17, 2010, between 3:30 pm and 4:05 pm? I know that I must be missing something somewhere.How do you search for info like this? I goggled "search files time Linux" and got about 38,300,000 results. I looked through the first four pages and did not see what I was looking for.Do I need to calculate how many minutes ago that is and give that to find.I really want to do this in the GUI so that I can operate on the files found without typing in so much stuff.

I'm looking to find a way to schedule my computer to wake up at say 7:00am. Every night before I go to bed, I put my computer into suspend so the fan doesn't wake me (old computer). I can't seem to find a task scheduler that allows me to be able to wake the system.

I have looked high and low for this, but to no avail. I am looking for a script to shutdown my computer when it reaches a specific time (say 10:00). I know about the shutdown command but if I use that I cannot shutdown my computer manually. I would like to be able to shutdown manually AND automatically.

I've been quite puzzled by the behavior of unattended updates - it seems it runs the updates at or before 7am (on all the server installs I've got). They are only set to do security updates unattended, but what I am wondering is if there is a way to change the time that they install? I want the updates to install early in the morning, at like 3am or such, so I can reboot the machine when I get up if needs a reboot.I found a few mentions about it, but nothing specifically talking about the time.[URL]..

I've just put together a 10.04 server using a GA-D525TUD atom board. I've installed gnome desktop too. I'm trying to get 4 sata drives to go into standby, but hdparm seems to be ignoring the settings. If i issue hdparm -y /dev/sdx the drive duly goes into standby and stays in standby until accessed. I've put entries in rc.local along with the hdparm.conf settings, but still no joy.
Hdparm.conf:
/dev/sdb {
spindown_time = 244
}
[code]....

I am trying to extract just a few files/folders from a Time Machine backup, but can't seem to find them. The drive is automatically mounted in Ubuntu, and am able to access after enabling view hidden files, the HFS+ Private Data Directory. But that is a jumbled array of thousands of numbered folders, with each taking a fair amount of time to open on this aging Dell running 10.10.
I've tried running the standard Places - Search for Documents, with 'Show hidden and backup files' enabled, but that won't pull up any of the search times I'm going for (and seemingly won't find anything at all on the drive). So, is there any way to decipher the directory tree so as to be able to access this data from Ubuntu? Or perhaps a file embedded somewhere in there that lists out the original structure, so that I can use it as an index to see what number correlates to what originally named folder?

Can anyone shed some light in this? Using Fedora 14-64, new install, 185 Opteron x 2 gig ram, sata hard drives formatted Ext4.However, in my home directory I have a folder for all my digital photos of which I have more than 20,000, and in another folder I have images and clipart of which I have almost 8,000. That is a lot of read only access to a significant number of files in my home directory.
How can I tell Fedora to not update the LAST ACCESS TIME of those files (specifically images) that will never actually be changed other than just being read. I want to leave that feature enabled for the rest of my home directory. I am trying t; improve my disk performance in Nautilus because whenever I access the folders with my images the system literally slows to a crawl and sometimes even the mouse stops working for several minutes until Nautilus has finished having its heart attack.

I am using openSUSE 11.2 and had the same issue once before in openSUSE 11.1 After some time, two domains I use very often can't be accessed any more, these are: Google and [URL]... (am doing some OO development recently). At the time where I write this post, only these two are "blocked".
When I try to access these two domains using Firefox, w3m or telnet, it tries to open the connection forever. Ping works fine. I tried opening the IP directly in the browser, but same problem, the connection never reaches. I know it's not a router issue, as the other computers can access these domains. Still, I tried to restart the router, but the issue persists. I tried restarting the network service (/etc/init.d/network stop + start), also nscd, without success. The only way I found to make it work again is to reboot. This problem reappears from time to time, after using the computer for a long time, and accessing these domains a lot of times. Note that I also use suspend to disk, so the "blocked" state is kept after resume. Only reboot "cures" it.

When I leave my computer and later return, depending on how long I've been away, I find the screen-saver running, the screen turned off, or the computer suspended, i get the error as specified below on a black screen:
Quote:
Ubuntu is running in low-graphics mode.
Your screen, graphics card, and input device settings could not be detected correctly. You will need to configure these yourself.
The message gives several options. Despite some experimentals, The only solution which I have found is to reboot and everything becomes fine as before.

Is there a way to set Linux to automatically log in to a specific user account and at the same time lock the screen? I want to save time and trigger various software that always should start up on boot, while leaving the computer unattended during startup (extra important and practical for remote control boots), by enforcing a 'screen lock' so that no-one can see what happens behind the login screen without entering the login credentials.

How do I get vlc to start at a specific time in a media file. I can do it easily in mplayer2, mpv but not vlc. Let's say the media file is named abc.avi (file format,container not important for this example.) Also the running time is around 2+ hrs. In mplayer2 and mpv I can simply do :-
Code: Select all$mpv abc.avi --start=00:59:00
And it will start running at that point in time.
In vlc, it also seems to have something at :-
Code: Select all[$] vlc --advanced --help
......
......
Playback control:
--input-repeat <integer [-2147483648 .. 2147483647]>
Input repetitions
--start-time <float> Start time
Now I don't understand what the <float> bit. I tried :-
Code: Select all$vlc abc.avi --start-time=00:59:00
But that didn't work. It's possible that it might be a bug, then again I might not have done it correctly.

I've experienced this problem with a distribution upgrade and then subsequently with a clean install of Ubuntu 10.04. Basically half the time that I boot up Ubuntu, it completely locks up with the following messages on screen (Sorry, I had to take a picture since it was locked up)However, when it does boot correctly, it pauses for just a moment after displaying the above text, and then displays a few additional lines, after which it goes on to boot 'normally'.
The next lines show 'plymouth' and 'ureadahead' processes being killed. If these lines show up the boot continues normally, otherwise the boot process hangs at the first picture.It is pretty frustrating to have to perform a hard restart during nearly every other boot, and the hangs seem almost completely random. Sometimes, it happens a couple times in a row, sometimes I can boot normally several times in a row. It also doesn't seem to be related to a cold start, versus a restart.

I was wondering if there is any tool or program that stores a copy of frequently used files eg. Binarys, program library's etc. in memory so when they are requested by the OS they load instantly. I'm asking because I have a system with plenty of ram but very slow hard disks. Having programs like opera and java/eclipse load from ram would greatly speed up their start time. Ideally they would be loaded into ram in the background after I log in. Of course all writes made to these files would have to be made to the files on disk for obvious reasons.I don't want the entire OS in ram because it will not fit, just frequently accessed files.
