Ubuntu :: Put Frequently Used Programs In Ram For Faster Startup Time?
Jun 12, 2010
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.
programs (especially Firefox, though I haven't used other programs much) stop responding rather frequently without warning and after some time they just start responding again. Apt-get also takes ages to unpack stuff when I'm upgrading/installing something, that might be related. According to top there is barely any cpu usage at all during these freezes. I had this issue on a stock Lucid install. When Maverick came out, I tried that one, and the issue still existed. On a fully upgraded Maverick system, it's still there as well. Windows works without a hitch, as does Ubuntu running under a VM on windows.
System specs:

How to make the system boot faster by removing the idle time between 5s to 10s? bootchart attached. It is Ubuntu10.04LTS by the way. One more hint, the screen black out for ~4s after "Begin: Running /scripts/init-bottom... Done." I don't know what is going on during that 4s, but my best guess is there is a way we can get rid of it. Bootchart can be found here:
My server is a VPS which is running with CentOS. I found a wield problem that the system clock always runs faster than the hardware clock. For example, I set system clock and hardware clock both on 20:00. After about half an hour, the system clock will be 20:34/5 which is wrong while the hardware clock remains correct (20:30).
I'd like you to know that I'm completely new to ubuntu. Just install it a couple of days ago. I have a bit problem with startup here, everytime I change anything in System > Preferences > Startup Applications it just keep coming back to default. I unchecked Penmount Utility, and it's checked again after next boot. Same thing happen when I add Guake Terminal. When I reboot, it's not there anymore. So basically, it seems that I can't configure my startup programs.
I installed 10.10 yesterday, and now whenever I boot my computer it launches 3 or 4 windows on startup for apps that usually run in the tray (Rhythmbox, Pidgin, Skype, and the mounter for my memory card). I was wondering if there is a way to just launch the programs to the tray. It worked perfectly in Lucid.
I've got an Ubuntu server installation with openbox installed. I also installed wbar and want to have it load with openbox. Is there a config file for openbox or anything like that?
I have somehow gotten two instances of Mediatomb running on my Ubuntu 10.04.1 how to get rid of one of them.There is one copy running as a daemon on system startup - that's the one I want to keep.There is another copy running when I log in with my user account - this is the one I want to prevent from running.I have looked in my Startup folder in the GUI and also in my .profile script for my user account but I don't see any references to mediatomb there. Where else should I look?I think the daemon version is running via an entry in init.d, but other than where I've already looked I don't know how to find out how the second copy is getting initiated during login. It only seems to show up when I log in to the GUI on Ubuntu - not when I connect to the machine remotely via SSH.
I'm unable to change startup programs. If I try and add or remove a program, any changes I have made seem to undo themselves. I suspect it might have something to do with being unable to save the session, but I really don't have a clue.
Just in case it makes a difference: I'm actually running Mint (Helena).
I have noticed a few problems when some screenlets are loaded before some others. I think that "Startup Applications Preferences" should have an option to arrange the order of their execution.
I recently made the switch from gnome to kde. After struggling for two straight days I finally have everything the way I want, and I must say that I am quite pleased with Kde. The one thing I want to do now is get my computer to start up without running printer applets and bluetooth and all that other stuff I don't need. I have had little luck finding any info on this one.
I've found mentions of this problem in Lucid Lynx, but this is a recent development for my system, since I've been running Ubuntu since Gutsy Gibbon.On start up my gdm theme/icons appear for a second, but by the time I've entered my keyring password the theme reverts to the system default (what Synaptic package manager looks like). It also does not load my start up programs Gnome-Do and Screenlets. My theme only appears if I go into the Appearances menu, and Gnome-Do only starts if I pick it from the Accessories menu (and I've gone into Gnome-Do's preferences and clicked on "start GNOME-DO at login"). About once in a blue moon it will load everything correctly.
Recently I have had a run of random errors on boot up. Finally, the quit button, top right of the screen disappeared permanently. I am convinced it is because I added Evolution to the programs that start automatically when I login to Ubuntu (auto login). Evolution uses the Internet connection which hasn't been successfully established by the time it starts. In the past, this would crash Ubuntu. It seemed to be fixed by this stage, but maybe not. Is there some way of delaying the startup of a program in the automatic startup list - to give the rest of everything time to settle in - before it starts trying to use other startup resources?
For example if my netbook runs on AC i would like it to start emesene, Skype etc. on system startup, but if it runs on Battery i want different startup programs - less of the same programs basically -.Is there some script i could use for this purpose?
I noticed that some applications are still in the startup applications list even after i have removed these applications.Would there be any app files left over anywhere / is there a command i can run to clean up the filesystem.Or is it just a case of removing them from the startup app list?
How do i disable startup programs in fedora 11. actually pulseaudio sound system starts up every time i log in. It interferes with the vlc media player running on wine 1.1.13(compiled from source). i killed the pulse audio process, and every thing works fine, but i have to do it every time i log in
I am using fedora 8, upto login screen it is fine. After getting password, automatically it starts some programs like, terminal, Thunderbird, firefox and nautilus.
Does anyone know of a good time keeping/recording program for Ubuntu that I can use to log hours spent on a project for billing purposes? I'm getting back to doing some web work to make some extra cash, and would love to have a program that does this.
Every time I start Ubuntu, I set up an ssh session to a server. In order to automate this I made an entry in startup programs like this:/usr/bin/gnome-terminal -e '/usr/bin/ssh name@server.com'Nothing happens when I log in, and I've checked that the command works.
We have setup squeeze workstations with gnome, citrix receiver and vmware-view client. Which startup programs and daemons, for example avahi-daemon can be normally disabled or what is disabled on your workstations?
I am trying to view the startup programs of init whenever I boot up, but don't know how to edit /etc/inittab file. I am running Fedora FC13 and my runlevel is 3. I have the following in my inittab file:
Quote: # # inittab This file describes how the INIT process should set up # the system in a certain run-level. # # Author: Miquel van Smoorenburg, <miquels@drinkel.nl.mugnet.org>
I don't know if it is just me but it seems like Ubuntu takes a long time to start up programs. For example, it takes me 10 seconds to start up "Ubuntu software center". My computer is a relatively fast one. It has 4 gb of ram and an intel core duo processor. I didn't install that many programs. Does anyone know what might be the source of the problem and how to fix it?
