Ubuntu :: How To Make System Boot Faster By Removing Idle Time
Jun 14, 2011
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:

After installing ubuntu 9.10. It's now been a month or so from a fresh reinstall.
Currently for some reason at times my computer slows down where typing starts to lag.
Is there any software that would speed up the linux os. Like for windows there is softwares that would check the registery for errors and shortcut errors etc and fix them.
I use free software like that for windows and works well. I just would like to know if I can get something like that for linux. I know linux dosen't use a regsiter but just saying software that checks the linux system for any errors that could cause the computer to slow down.

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).

My hard drive all of a sudden starts to read and write all on its own for around 15 seconds at a time while at idle or while I am just browsing the net. At first I thought it was from cron running but I have that disabled.

I have an Ubuntu Server 10.10 install on a VIA C7 chip. It seems to pause for about 5 min on a USB component.
It is a fresh install, here is a snip from my messages log code...
My KB is USB, so I would rather not disable it if at all possible. The next time I can take it down, I will test disabling it though...

When booting Fedora 11, my system hangs for a very long time on starting udev. Sometimes I get an I/O error. However, my hardware is fine. I do eventually get in to the system.

Running Ubuntu 10.10 on a Sony Vaio VGN-NR430E laptop.My system had been running noticeably slow lately, so I decided to poke around the system monitor and see what was eating my resources. Xorg peaked at around 50% cpu, so I decided (in a rash decision) to remove it. Went to Syanptic Package Manager -> completely remove all "Xorg server" packages ( was alerted that Xorg itself would have to be reinstalled for this to happen, "OK" ). After Syanptic finished, I looked back to the System Monitor and saw Xorg still there, still eating CPU. Out of frustration, I selected "End Process".The grub loader still works so I can switch between kernel versions and "recovery" mode, but a normal boot simply takes me to a black screen. I tried sudo apt-get update from Recovery mode, only to get an error when connecting to the repositories.

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.

One of the most common tasks I perform is browsing for files. I have always wanted my file manager to be lightning fast. That is, I open it and it loads directories instantly. No waiting, just opening them right away. This remained always a wish, as in Windows and Ubuntu on a variety of machines I always see that it takes a little while for the program to load directories. I am not talking about folders with thousands of files or anything special. However, I have seen others who have Windows (XP in this case), and their Explorer opens right away. Browsing folders is very much instant.
Is there any way to achieve the same in Nautilus? The other computer is not very modern or super fast, at all.
I have a laptop with SSD drive which I hoped would speed up this process, but this is not the case. On both my laptop and desktop I often see the 'loading' symbol, and files often appear after the folder view has opened (they just appear all of a sudden). This happens with folders I rarely visit but also with folders I often open.
How are others' experiences? Can Nautilus be instant? Is this a configuration tweak or hardware issue?

I need to write a small application which needs to detect if the system time is changed by an another application/user and perform some action as soon as it is detected (maybe log the data that time has changed, along with info about which application/user changed it).
How can this be achieved?
I have good programming experiences in shell script, c and beginner level in python.
I don't need to know when it was changed, just need to know who/what changed it.
The system uses NTP to sync the time, but it is also possible for anyone/any application to change the time(for eg: using the simple "date" command as well).

I have Ubuntu 10.04.1 32bit installed on my flash drive so wherever I go I can have my own mini personal computer, but one problem I'm having is every computer it is run on the next time it's rebooted to the OS on the hard drive it has UTC time instead of the actual time for the timezone you're in that Windows uses. So is their a way I can make Ubuntu not automatically change the clock to what it wants?

I like the new 11.04 ubuntu, especially the left panel. However, performance dramatically dropped when i did the upgrade. What I'm asking is, how do I improve the performance of Natty?
If I can't, how can I downgrade back to 10.10?

I know a bunch of commands and I am comfortable using the terminal, I even set a powerpc server but I can't figure out how to remove epiphany on this new computer I'm setting up. I didn't install anything with tasksel. I installed gnome and xorg afterwards... I load it up and 'startx' just fine. then I check around for the programs that were installed. I lik'em gimp, lot's of utilities. gedit. anyway I find epiphany, which I have already established that I dislike, I immediately go to the root terminal (another nice program that comes with gnome) and type apt-get remove epiphany-browser-data the output says it will be deleting gnome... however I have researched and found these are simpy meta packages that don't really matter.... however under the section that states all the packages that will be removed by autoremove there is a huge list... I doubt these packages are safe to remove. how to remove epiphany without removing a huge amount of probably needed software

I've been having a problem on my AMD based machine, 4cpu, gigabyte ga-ma78gm-s2h Mobo, 8GB mem, two 2 terabyte Sata HDs.One thing I've found is that any kernel after 2.6.32-17 has a randomness at boot time whether the system will completely boot or not.
For instance just today I downloaded and installed 2.6.32-24
It fails to boot (I've tried cold boot, warm boot).Running its repair also fails to completely boot.My experience is that if I keep trying it "may" eventually boot but I believe there was some change after 2.6.32-17-generic that's causing the problem.Because as with 2.6.32.23... which also fails to complete bootup many times... eventually my guess is that 2.6.32.24 will also boot "sometimes".But why does 2.6.32.17 always boot for me? Something changed and its not my setup.

After some idle time Slackware hangs up/freezes. When, for an example, i turn on music i can hear it on idle time but after some time music still plays but i'm losing picture (monitor detects no signal), num lock is locked, led on keyboard are turned on but won't turn off while pressing num lock. I've switched off power saving options in Slackware and on bios setup.
My spec is:
X4 620 (without overclocking)
AMD 760G (Radeon HD 3000)
Catalyst 11.5 for Radeon graphic.
BTW - computer works fine with Windows. Also, with Slackware i can work for an hours, many hours and everything is fine but as soon as i leave it for some amount of time = it hangs/freezes. There is something wrong with hibernation. Not always computern is turned off correctly. TV is switched off, slackware logged off but i hear drives working and cooler fans. It should be switched off completly.

I can use the gconf-editor to disable the screen-saver lock and set it to activate when its idle. But no matter what I change /apps/gnome-screensaver/idle_delay to, the ScreenSaver UI is never updated and stays at the default 5 minutes. There seems to be no link between the slider bar in the ScreenSaver Preferences and the value that lies at /apps/gnome-screensaver/idle_delay...
The reason why I'm doing it through gconf-editor is so a start-up script I have created can use gconftool-2 to alter settings for certain users on login.
Is this broken in Ubunto 10.04 or am I looking in the wrong place.

Anyone have an alternative to gconf-editor for changing the idle dim time? I have a Vaio, which hasn't exactly been compatible with ubuntu but I've been making it work.What I'm looking for is an alternative, like the the one I'm using to control the back light (nvclock).

When I haven't run yum for a little awhile, it's slow to start up because it goes through all the progress bars of downloading from different repositories. specially, just now updates/primary_db had to download 5.5MB.
Is there some way to automate this so it happens in the background and not when starting up?

We have 2 applications set as S96 and S98 at rc3.d and rc5.d simultaneously. Both applications create a system V shared memory segment by calling shmget.If the system boot at runlevel 5, both applications can obtain their shared memory segment id correctly, i.e. 98305 and 131074 individually. While there is a root owned segment id 32768 takes first seat on the list. This is the id list:
root, 32768
S96_app, 98305
S98_app, 131074

I am running 10.04 (i686) inside kvm-qemu client. The host is a headless 10.04 (x64).The issue is that the screensaver does not activate after a certain period of idle time (1 min). I can successfully activate the screensaver by running gnome-screensaver-command -a. It appears, then, that idle time is not being registered correctly. There are some very sporadic logs in daemon.log:
Code:
./daemon.log.1:Dec 1 11:01:24 myserver gnome-session[2166]: WARNING: GSIdleMonitor: IDLETIME counter not found
./daemon.log.1:Dec 2 12:35:53 myserver gnome-session[19953]: WARNING: GSIdleMonitor:

I am a GNOME user but because of the release of GNOME 3 i decided that i may have to start using KDE. So i installed KDE 4.6 from the qt-kde debian repository. It works more or less OK but i have a problem with the performance. It just doesn't feel as snappy as GNOME. For example if i have minimized Firefox when i maximize it it takes about a second for the window to draw and until then i just see and empty window. Or when i open nautilus it too takes a little to open and draw the window. Overall KDE seems a little unresponsive. Is this normal? And second, from time to time there seems to be huge performance issues - KDE suddenly becomes very slow - programs take a while to open, and the windows draw even slowlier than what i described previously. Also whenever there is a slowdown (like for example when i start a program) i hear some kind of scratching noises from a my laptop - like there is a heavy hard disk activity. I've heard that kind of noises before when doing something very demanding like compiling or archiving something.
Is there any way to make KDE more responsive and faster. I have disabled strigi and nepomuk.
I am running KDE on Debian Unstable with kernel 2.6.39-1-amd64 and NVidia driver 270.41.19 on a Thinkpad T61 laptop with Intel Core 2 Duo T9300, Nvidia Quadro NVS 140m and 4GB of Ram.
