I installed bootchart and had my boot times analysed. Unfortunately, I can't make head or tail of the resulting PNG file. Could someone take a look at and tell me what I should do to decrease boot time?
View 2 RepliesI have Ubuntu 10.04 installed and although I had some problems initially, everything works fine now. I'm just bragging about that. I do have some strange "issues" with my boot. I know that Ubuntu is supposed to boot with only plymouth visible, but before I see plymouth I have a fairly long period of time when I see nothing but a console cursor (a.k.a. caret) blinking. I'm no expert in reading bootchart charts, so I'm attaching it for some feedback. I have no idea how and what to optimize.
My boot is ~40 secs as noted on the bootchart, but it would be nice to cut some fat if possible. Also, my StartUp-Manager is displaying some veeery long boot options. It doesn't look nice. I guess he's reading /boot/grub/grub.cfg but I don't think I'm supposed to see all that. my boot and shutdown screens are very low res and very ugly, often flickering on updates. I have 10.04 setup at work as a web test platform on a very old/crappy PC (Intel GFX) and bootsplash looks much nicer than on my home laptop.
I managed to install a second hand 10Gb HDD on my old P4. I want to see how I can use this extra disk to speed up Ubuntu 10.04 if possible.
I installed my swap onto this second drive but since I never use swap I can't see any real improvement. Next, I'm considering the creation of a new partition on that disk that would handle /tmp. Could that improve access times?
Finally, what other tricks could I use with this 2nd HDD to speed things up?
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.

I've been a long time Windows user, but I've started a small firm and because of lack of funds, I've decided to install Ubuntu on my company's PCs.I have 8 PCs in total - 6 of them with Intel CPUs, and the last two with AMD CPUs. I bought the extra two computers because I've managed to find an extra two people to work at my company, and AMD-based PCs are cheaper so I've decided to buy them instead of Intel.Long-story short, I've installed Ubuntu 9.10 and boot time takes about half-an-hour. After the computers finally boot, USB hardware doesn't work at all. I was forced to buy PS/2 keyboards & mice and they both work fine after the PCs boot.I don't know what's causing this delay.I've enabled Cool 'n Quiet from BIOS.I've tried several instructions like editing the /etc/modules file.I've installed cpufreqd, tried to configure it, but it didn't work.I've check the CPU stats and my CPUs are running at 800MHz. I can't believe nobody managed to fix the 800MHz problem as I've noticed it's quite common among AMD Ubuntu users. I think I've tried almost anything that I've found on this forum.I can't keep asking my employees not to reboot their PCs. Both Chrome/Firefox crash a lot on Ubuntu so they're forced to restart their computers.The computer specs are: AMD Athlon II X2 240 dual-core @ 2.800MHz, 2GB RAM, 500GB HDD, etc.

View 9 Replies View RelatedI've got two laptops running Ubuntu. Both have had Lucid installed from the live cd. I have upgraded one of them to Maverick. Both distributions are running great after they boot up, but I haven't experienced any faster boot times with either distibution. Both boot to Bios and then the screen goes black with a blinking cursor in upper left corner of the screen. The black screen remains for 30 to 45 seconds and then I get the Ubuntu splash screen for maybe 5 seconds, and then desktop. Why am I not seeing faster boot times? I realize 45 to 60 seconds is good compared to other os's, but I anticipated much faster boot times. Shut down on the other hand is quite fast at maybe 5 to 10 seconds. Does anyone else get this black screen on boot? Seems like wasted time cause I can't tell what's going on during the time there is a black screen. This is not a real big deal breaker, as I don't reboot very often, but I just wonder why bootup isn't faster.
View 7 Replies View RelatedI'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.
This on a Vostro 1220 Laptop w/ Intel 5300 wireless:
A.I have long boot up time.I think it's because of the eth0 network search which I don't use.I have an intel wireless 5300 card running.How can I speed up the boot time, i.e. disable or change the eth0 at boot, the searching?
B:When I restart or shutdown, the screen flashes repeatedly and gets some garbled colors along the top before finally rebooting looks like windows ME or something).This vostro has an intel x4500HD vid chipset in it.
C.How do I get into gnome configuration editor to turn on Metacity compositing? Alt-F2 and run gconf-editor doesn't do it. I don't do compiz, but need compositing.
D.I need to install Chromium Browser as it sync my bookmarks.I have RPMforge enabled btw also...how can I do that? I.e. rpm repo for chromium?
This will help me get off to a running start so I can get up to speed on CentOS..

I have installed "open-SUSE 11.4" on a "500GB Free Agent External Hard Drive". I didn't have any problem in booting since last week that I booted it from my laptop. Also I did it before several times from then when I try to boot it e.g. from an "Intel(R) Core(TM)2 Quad CPU Q9400 @ 2.66GHz" PC the time between loading INITRD and starting boot sequence messages lasts nearly 30 minutes!(i didn't actually measure it but it take a long time in the same order). after starting boot sequence which is showed on monitor everything looks normal. e.g copy of files would be done by speeds between 2MB/s to 30 MB/s depending on the targets.I used to use the external hard derive to boot from different laptops and PC's from start but I didn't have such a problem anytime.

View 1 Replies View RelatedBasically I'm wondering if there is any way to lighten Gnome and Ubuntu I would like to keep Gnome if possible. I am a pretty experienced linux (or for you hardcore GNU fans GNU/Linux) user having used it for almost 4 years and I just built my Arch system but have found that alot of the functionality that I've come to love about ubuntu isn't in the default Gnome package but that Ubuntu's Gnome is heavily modified so I want to switch back but do to my lack of modern hardware I can't run Ubuntu as smoothly as I want.
Below is my current hardware.
Code:
Intel Pentium III 733mhz
512mb of ram
8gb Hard Drive
and a Dvd Drive
Nvidia Geforce 6600 265mb pci gpu
100 watt power supply
I am also a Developer so I know I can compile the Kernel my self and remove some not needed junk and optimize it. But I was wondering are there some Highly intensive processes that don't really need to be running? The only thing I would be using Ubuntu for is Web Browsing, Coding, Gimp, Text Processing and probably Music; thats really all I need I don't do much else besides that.
tl;dr:
Basically all I'm trying to do is lighten Ubuntu and Gnome without putting 3 days worth of work into it.
I am running a ubuntu desktop machine as a server and use VNC from my windows machine to login via a LAN to the ubuntu machine. The login session is very sluggish and frustrating.

I have 3 gig of ram and the server is a dual celeron machine

However, the battery is still a bit less when compared to Windows 7 (2:00 vs 2:35, but it came with optimizations on W7 so that might be the reason. A comparison of power used: 25w of power on Ubuntu vs 17.5 on W7.
View 2 Replies View RelatedI have a Gateway Laptop which is dual-booting Windows XP SP3 32-bit and Ubuntu 10.04, also 32-bit. The 64-bit version, would not install on my computer, even though the computer has 64-bit capabilities. It doesn't bother me that I use the 32-bit version, but something it is now doing seems to be affecting the way things work on my laptop. The computer has 4GB of RAM in it, an AMD Turion 64 X2 processor, and an ATI Radeon X-series graphics card. The monitor has HDMI capabilities. On the Windows side, it handles full-screen programs and operates very quickly. On the Linux side, I can also run things quickly. However, most programs on the Linux side are much slower-running than they would be on the Windows side.
Something I notice when my laptop goes into fullscreen on the Linux side, is that the color quality goes way down. You can see that it is trying to run in apparently 256 colors, and each individual pixel is very visible. It does not do this on the Windows side. Also, programs that I run on this half of the computer are very laggy, slow, and inefficient. I know that my computer has the video and processing power to handle these programs with ease, but it isn't utilizing all of it. How can I make Ubuntu run at a higher speed overall, by taking advantage of all four gigs of RAM and this 2.4 GHz Turion processor to run everything like Windows does?

View 9 Replies View Relatedafter a recent foray into Ubuntu. Every day is a school day at the moment, so please be gentle! I recently obtained an old IBM Thinkpad T41 which I've made dual boot Windows XP and Ubuntu (windows was my backup option - it's installed but with none of the drivers; thankfully I've not yet hit a problem Ubuntu can't handle!) and which is connected up to the TV in our lounge. I have installed XBMC on it, and we're currently enjoying having access to all sorts of multi-media and iPlayer in the lounge. The thinkpad connects to our home network wirelessly, using the Thinkpad's built in wireless hardware - providing a whopping 11Mbps connection. Our media is all stored on NAS on the network, and I thought that even full 54Mbps wireless would not be fast enough to stream videos smoothly onto another machine.
However we have two windows laptops (one windows 7, one windows xp) which have 54Mbps connections and they can stream the videos smoothly from the NAS, so clearly I was wrong (wer'e not talking High def or blue ray rips here or anything). So my first question. Does anyone have an recommendations of a 54Mbps wireless card (PCMCIA preferably) that is compatible with both Ubuntu and the Thinkpad so that I can improve it's connection speed to the network? I have a "Max Value" branded card in the windows xp laptop (bought cheaply from Amazon) that I tried to but failed miserably to get working in the Thinkpad with Ubuntu last night. All hints and tips welcome....
Second question: Improving video playback on the thinkpad. Some of the videos were a bit choppy, which I thought was just to do with video quality. However having been playing them on the windows xp laptop - Sony Vaio PCG-FR215S, so similar in age and processor speed to the thinkpad - they play absolutely perfectly. So what are my options for improving the video playback on the Thinkpad running Ubuntu? - Upgrade memory to 1GB from 512MB? Will this make much difference? The sony has been upgraded to 1GB, which is why I ask the question. Do I have any options on the dedicated graphics processing hardware front? I'm guessing they are severely restricted as it's a laptop, but thought I'd ask as obviously I'd only be interested in something that is supported by Ubuntu.
Nvidia acceleration is enabled in Ubuntu, and in XBMC. The playback quality in XBMC is comparable with using VLC so I don't think there is anything XBMC specific to be concerned with at the moment.
