[SOLVED] Boot speed

Sup,
I have just installed the system. I heard that Arch is supposed to boot very quickly, but after installing just Gnome it was actually starting slower than fully bloated Ubuntu. I changed the daemons a little, and its now significantly faster but still over 30 seconds (Ubuntu on minimal install takes about 25 seconds on my machine).
This is the order I am using:
@gdm @syslog-ng @alsa @network hal @crond @fam
Its probably totally wrong. What can I improve and what are other effective methods to speed the boot up?

oh god. i tried the quick init script and it broke something
so i uninstalled, and replaced my original inittab. it and now i can't boot into runlevel5 anymore.
here is my inittab
# /etc/inittab
# Runlevels:
# 0 Halt
# 1(S) Single-user
# 2 Not used
# 3 Multi-user

Often a 'clean install' will reduce the boot time of a MBP. Please look at these instructions and decide if this will be right for you. Note that user data should be backed up before exercising this option.

P35 Neo Questions about USB boot speed (New query)

i see it's an old topic but i have the same problem with slow USB Boot on a MSI P35 Neo2-FR mainboard.
i have tried something like 5 different USB drives and all are the same. the problem is when it's tring to boot from USB. there is some missing support for USB booting from BIOS , i don't know.
i had a BIOS from 2008 and i have updated to the latest version but nothing solved my problem.
i have tried to boot from USB with a linux live environment, windows live CD or i have tried to install windows from USB drive. all of them with very slow reading (instead of max 2-3 min loading time it takes almost 20-25min at least..).
when the system (windows) loads up the speed of reading the USB drives increse dramatically and all things gets back to normal.
with the same USB drive on several computers all the above works without any delay or very slow reading. so this i think it's the motherboard or the motherboard BIOS but i don't have a clue on how to fix this issue.
any help will be more than appreciated. thank you.

AngelTudorache please read the Forum Rules and don't resurrect nearly 4 year old threads. >>Please read and comply with the Forum Rules.<<
Please post your full system specs >>Posting Guide<<
Do you use the case USB ports or the MB USB ports ? Have you tested the MB USB ports by disconnecting the case USB headers ?
Suggest you transfer a large file from the HDD to a USB device or from a USB device to the HDD and monitor the transfer speeds. Anything between 15 and 30mb/s is normal for USB2.

[Solved]Boot from USB HDD - Root device doesn't exist. Major/minor

My problem is that the kernel seems (or starts) to load, but then I get an error:
Root device 'UUID=1234 . . .' doesn't exist.
Attempting to create it.
ERROR: Unable to determine major/minor number of root device "UUID=1234 . . .'
You are being dropped into recovery shell
I found a few links on the web and in the forums, but nothing that really solved it for me. The solved ones usually downgraded the kernel. I haven't done that yet. I thought I'd try here first.
I have a 320GB USB HDD that I have been using to experiment with different linux distros. I have a few working successfully (OpenSUSE,Mint,Ubuntu,Debian,Fedora,etc). I'm very new at this but have been reading a lot and putting a lot of time into it. I have legacy grub loaded on the MBR and use the menu.lst on my openSUSE partition to boot everything. Because the partitions for some of the distros are so far into the disk I needed to create directories on openSUSE's /boot directory to contain the kernel and initrramfs files (like /boot/fedora). This seems to work for the other distros. I did the same thing for Arch.
So when I installed Arch I haven't used the bootloader section of the installation.
I'm using the 2011.08.09-netinstall-i686.iso Live CD.
I tried a few things including:
1. changing the HOOKS in /etc/mkinitcpio.conf
a. adding usb to the "HOOKS"
b. removing and adding autodetect
c. adding and removing "sata_sil" (although I'm not even sure if my device uses it)
2. changing the kernel line:
a. from using "UUID=" to (hd0,1) to sdb1.
b. added rootdelay=8
3. repartition all of my arch partitions using cfdisk from my Live CD and reinstall. I used gparted on OpenSUSE to do it the first time.
This may be connected. When I fdisk -l from the Arch Live CD I get extra data and an error for each of my arch partitions (and only my arch partitions):
Disk does't contain a valid partition table
When I fdisk -l from OpenSUSE I don't get the data paragraphs or errors about the arch partitions?
Here is my /etc/fstab:
# /etc/fstab: static file system information
# <file system> <dir> <type> <options> <dump> <pass>

I'm IN! Thanks everyone for your suggestions!
The arch system didn't like the identifier I was using for the root partition. By looking at the /dev/disk/by-id while the arch system was running, I could see what the system wanted me to call the partition. So after the system error'd-out and I was in the recovery shell at the [ramfs /] prompt:
# ls -lF /dev/disk/by-id > by-id.txt
# vi by-id.txt
I could have used any of the identifiers listed in the by-id (there were 3), by-uuid(1), by-label(1) or by path(1). I tried them all. I had to write these down by hand because it is a ram filesystem.
The article that finally got me there is:
https://wiki.archlinux.org/index.php/Pe … ice_naming
Anyway my openSUSE grub menu.lst ended up like this:
####arch on sda10 - legacy grub

[Solved] Boot error: /etc/rc.d/functions /etc/netcfg doesn't exist

Hi everybody,
Well, after a bit of playing around, wiki reading and trouble-shooting, i now have an automatic wireless connection at boot via netcfg2 and my wireless profile. Great stuff.
By the way, whoever wrote this: http://wiki.archlinux.org/index.php/Net … _netcfg_v2, you deserev a medal.
Anyway, to the problem. I get an error message at boot which informs me that there is an error in my /etc/rc.d/functions file at line 155, stating that /etc/rc.d/netcfg doesn't exist (which is correct).
However, when I look at the functions file, I cannot for the life of me see the problem.
Line 155 is: /etc/rc.d/$1 start
154 start_daemon() {
155 /etc/rc.d/$1 start
These are my daemons:
DAEMONS=(syslog-ng cups hal avahi-daemon sshd snmpd xinetd portmap netcfg net-profiles)
The obvious thing would be a problem with the netcfg daemon, but everything works ok, so go figure.
The only real reference i found was this:
http://www.archlinux.org/pipermail/arch … 03699.html
I'm fine with an optional dep - how about we throw a comment above
'NETWORKS' and have rc.sysinit throw a warning it NETWORKS is defined
but /etc/rc.d/netcfg isn't found?
Any help appreciated.

[SOLVED] Download speed is slow while playing certain Steam games

This is a weird one: When playing Steam games my download speed (everywhere) drops to a fraction of what it should be (roughly 1/10th). My upload speed is unaffected.
I don't know how long this has been the case but I think it's fairly recent since when playing games I often tab out and do stuff on the net. I would've noticed.
This doesn't happen with Portal 2, Civ V, Guacamelee or Xcom but does happen with Rochard, Steamworks Dig, Gateways (2d puzzle platformer) and Awesomenauts. I was looking for a pattern but I fail to see one.
To be clear about the problem: If I start one of those games and tab out my download speed is 1/10th what it should be. If I exit the game my download speed returns to normal instantly.
I've checked for obvious stuff like Steam downloading in the background (it's not and nor is anything else - no unusual network activity at all). I've checked for mere coincidence - signal dropping/interference and so on and that seems not to be it either. It's also far too consistent and, as I say, upload is unaffected for some reason.
I don't even know what info to give with this one or how to begin tracking it down so any advice will be received gratefully.
I'm running Arch 64bit, all up to date.
05:03.0 Network controller: Ralink corp. RT2561/RT61 rev B 802.11g
Which I believe is using the rt61pci module.

Ok, well, I *think* I've sort of solved it:
I went through various wifi channels and found that the degree to which my download speed was reduced varied depending on the wifi channel I was on. So I left a game running and watched the download speed and the speed of my CPU and GPU as they clocked up/down and it seems that one of them is managing to interfere with the wifi signal. Or at least that's my best guess. High wifi channel numbers seem to be affected least (significantly so) so ... yeah.
I don't know if this makes sense technically (and no idea how I've never encountered it before) but... that's my guess.

[Solved] Boot process hangs for installed Arch and installation usb

Hi. I've been using Arch Linux for around 6 months now and I'm in love with it. It is now my primary OS. However, I might have done something or performed some update, and I can no longer boot into Arch. The boot process hangs right before it should show the login screen (I'm using Gnome 3.6 with GDM). I see the following messages on the screen:
Loading Linux core repo kernel ...
Loading initial ramdisk ...
/dev/sda3: recovering journal
/dev/sda3: clean, 330610/1749664 files, 5585671/6996827 blocks
And then it hangs right there. I have to hard-reboot after this.
I then tried to boot using the Arch Linux Installation USB (archlinux-2012.12.01-dual.img), which also hangs at a particular point, before it should show me the prompt. I took a picture of the screen where it hangs: Screen Capture. This is an issue with just my laptop, because the USB boots just fine on another laptop I tried.
I also have Windows 7 and Ubuntu 12.10 installed on my system, and I'm able to boot into both of them.
I have 2 hard drives: /dev/sda is a 120GB SSD, and /dev/sdb is a 500GB hard disk. My partitions are as follows:
sda1 - Windows 7 100MB System Reserved Partition (boot flag enabled)
sda2 - Windows 7 OS
sda3 - ArchLinux (boot flag enabled)
sdb1 - Ubuntu 12.10 (boot flag enabled)
sdb2 - Just data

Ok.. So my Arch Linux randomly decided to work. I'm sure I didn't do anything between my last "not working" state and my current "working" state. Below are a few things I tried:
I thought of trying an earlier build of ArchLinux, and downloaded archlinux-2012.11.01-dual.iso and made a bootable USB out of it. It still hung.
I was getting error messages during Arch boot that the last access time for the disks was at a future date. I found out that Ubuntu was using localtime instead of UTC and screwing up my hardware clock. I fixed it, and thought maybe the time issues were causing the boot problem. But fixing time didn't solve my problem.
I chrooted into Arch from my Ubuntu install, ran 'sudo pacman -Syyu' and updated my Arch install.
I thought maybe GDM isn't starting up. I re-enabled the service using 'systemctl enable gdm.service'.
I removed OpenNTPd and installed NTPd. Enabled the daemon using 'systemctl enable ntpd'
None of the above solved the problem, and rebooting to Arch still hung the system. So I stopped fiddling with it yesterday. Today, as usual, I just tried logging into Arch.. And it just worked out of the blue. The solution to me is as mysterious as the problem.
I told this to my friend who introduced me to Arch, and this is what he said:
Damn it computers, you were supposed to be deterministic!

[SOLVED] Booting from Asus U3S6 SATA Controller fails

Since the SATA controllers on my mainboard stopped working yesterday, I bought a Asus U3S6 Controller in the hope to work around the problem in this way. The drive is detected by the BIOS and GRUB is invoked correctly. However, when I try to load the kernel, I get following message:
Waiting 10 seconds for device /dev/sdb3 ...
ERROR: Unable to find root device '/dev/sdb3'.
You are being dropped to a recovery shell
In the recovery shell I cannot find any disk device under /dev/. Is this kind of booting supposed to work? When is the PCI controller actually detected and activated by the kernel?
Any help appreciated!

I solved the problem.
I used used the chroot guide to modify my environment:
I had to add ahci to the list of modules in /etc/mkinitcpio.conf and rebuild it with
mkinitcpio -p linux
This will then load the AHCI module at boot time and enable the SATA devices.

[SOLVED]Boot hang after recent updating issues

I am having issues after the last update. First, I made a mistake of holding back the filesystem package. Because of this (at least I think so) I was having an error that said it could not boot because at boot it said "/sbin/init does not exist". I solved this by upgrading the filesystem package by chrooting from a live arch usb. Now I am having an issue where my system hangs at boot, I believe it is right after systemd runs fsck although I might be wrong. But after maybe 5 minutes it just starts as usual... my ususal boot time is less than a minute. What should I do?
This is from a thread i accidentally hijacked:
cfr wrote:
Try systemctl --failed and or examine the journal for clues.
Post fstab. Are all of the disks referred to there available when you boot? If systemd can't find them, it will basically wait until it times out and I think that's about 5 minutes and then it will continue booting (assuming it isn't missing anything critical, of course).
My fstab:
# /etc/fstab: static file system information
# <file system> <dir> <type> <options> <dump> <pass>
# /dev/sda6

Would deleting the second /dev/sda6 fix it?

Thanks jasonwryan So my exact boot time was 1 minute and 34.151 seconds (which is not unbearable but like i said it used to be in a matter of seconds)... The kernel took 2.790 seconds and userspace took 1 minute and 31.361 Output of systemd-analyze blame :

Now maybe I am wrong, but these don't add up to 1 min 31 seconds...It actually adds to about 9 seconds which is probably my old boot time.. What am I missing here?

[solved] Boot issues after update caused by LVM

Hi,
I know that there are some threads regarding boot issues but I haven't been able to find a solution for my problem.
I have the following partitions:
$ lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:0 0 74.5G 0 disk
├─sda1 8:1 0 128M 0 part /boot
├─sda2 8:2 0 2G 0 part [SWAP]
└─sda3 8:3 0 72.4G 0 part
├─vg_trinity-root (dm-0) 254:0 0 10G 0 lvm /
└─vg_trinity-home (dm-1) 254:1 0 25G 0 lvm /home
I have
USELVM="yes"
in my rc.conf and the following im mkinitcpio.conf:
HOOKS="base udev autodetect pata scsi sata lvm2 filesystems"
Still, when booting the volume group does not get activated. The following message appears:
:: running hook [lvm2]
Activating logical volumes...
No volume groups found
Waiting 10 seconds for device /dev/mapper/vg_trinity-root ...
ERROR: Unable to find root device '/dev/mapper/vg_trinity-root'.
You are being dropped to a recovery shell
Type 'exit' to try and continue booting
sh: can't access tty: job control turned off
[rootfs /]#
At that point I just run
lvm vgchange -ay
exit the shell and booting continues. So somehow activation of the volume group does not occur early enough. I reinstalled udev, mkinitcpio, linux and generated a new boot image as proposed in https://bbs.archlinux.org/viewtopic.php … 4#p1059124 but to no avail. Is there anything else that might be wrong with my configuration?
Thanks for any help.

Help by Forum Mods solved slow speed

Thank you to the replies in the super slow thread where I posted. A big thank you to Stephanie a Forum Moderator who guided me back to a better service and speed than before the issue started.
If you have lost tithe good broadband speed you once enjoyed I recommend you follow the guidance of the Forum Moderators. Like me your frustration will hinder any progress and patience is needed, two weeks in my case.
I had 6 Mbps in November, then down to .25, I blamed BT for capping throttling me, and raged at those on the forum that insisted Bt don't do this ( deliberately ) vented my anger at BT vowing to move to Sky (which I will not).
here is what I know now....
I caused my own problem, I switched the power of the hub when away for a week, the exchange assumed a power cut which would do the same and automatically registers a fault on my broadband cuts the speed to 0.25mbps ( No human BT dictator flicks any switches or choses me maliciously ). The automated procedure of the computers at the exchange is now to monitor my BB connection and if there are no more outages or faults gradually bring the speed back up. For some this will happen over 3 to 5 days. I never had more than 3 hours without dropping tithe connection so that was not going to happen.
I had two unforeseen further problems, a fault on my voice line, BT eng summoned by the Forum Mod, and faulty connection sorted. Still the BB connection was dropping inside a 12houri window. I noticed that there were now as many a 5 Bt hubs and 3 others being offered by my wireless connection. Stephanie then guided me on changing the wireless frequency of my hub, to avoiinterference from my neighbours hubs. Problem solved.
I now have 10.5 Mbps and a very stable connection, I was able to move the hub to the end of an extension ( now I understand the Adsl filter) and use an Ethernet cable to connect to the Sky box for on demand. droop romp or lag on Netflix from the Xbox.
A long post but I hope it will help the frustrated understand the papered problem can be fix and the team here can help, but patience is required.
Seasons Greetings to all the forum and especially the Moderators and Team.
ps. If you are going to correct my description of what happens when the exchange drops the speed don't be to techy, not all BT customerthrill understand.

It is a regular problem i am afraid and will only get worse the more wireless routers that come on line don't worry about the predictive text it winds me up as well

[Solved] NIC speed slowdown

Hey all,
I updated the bios on my motherboard last week, and when I did that I noticed the network speed was slower than normal, and then yesterday I attempted to copy 15 gig of video files, and was shocked to realize that I'm only connected at 10megabits, on my gigabit lan.
I finally, (fingers crossed) got the bios back to where it should be, and I was able to successfully connect my onbaord nic to my lan at 1gbit. I then booted to Arch and I'm running at 100, better than 10, but not 1000.
I am going to reboot back to windows to see if I can get the 1000 again.
In the mean time, I'm not sure what to look for in Arch to help me determine the network speed, and what tools to use.
Could someone guide me in the right direction?
[EDIT]
Nope, the speed did not hold, when I rebooted to windows, I was running 100mbps. how can I tell from within linux how fast my nic is?
--nixIT
Last edited by nixIT (2010-06-26 21:28:04)

Thanx., I installed networkmanager (not sure if it is better)
however, I also reflashed the bios, pulled out the battery for 30 minutes, powered on, loaded defaults, came into linux and 1000Mb/s. w00t! I rebooted several times (staying in linux and not going to windows) and still at 1000Mb/s.
I will call this closed for now.

*SOLVED* Boot from ubs-memorystick

Hi out there, hope someone can help me with this problem. I have made a regular dos-boot-disc on a usb memorystick, have tried 2 different, sandisc and a noname.
I have a pt880 motherboard and when i press F11 during bootup i've got the bootmenu and the stick is shown there. I choose it, but after all bios checks it says something like "search for boot records on usb bla bla bla". And there it hangs, the whole computer hangup. :(
Anyone got an idea what i have missed? I mean if the bootdisc is wrong done (but its not) it should say it cant find any boot record of boot files.
???

[SOLVED] Boot loop after upgrade

Hi all,
When i try to boot arch, even in fallback mode, boot fail and go in loop.
loop happen just after the display of nvidia logo, then it try to do something (not showed in screen), it fail, and the nvidia logo is showen again.
I can't access to GDM, i can't turn off computer (have to remove battery from my laptop), i can't access to terminal/console/virtual console.
Last things i've made:
- full update system (pacman -Syu)
- changed /etc/environment adding this line (i was trying to solve tearing problem):
CLUTTER_PAINT=disable-clipped-redraws:disable-culling
CLUTTER_VBLANK=True
nothing seem to work
i've already removed the 2 added lines from another linux distro i've on the same computer, so i don't think /etc/environment is a problem here
don't know what to do and how to solve...
any hints?
thanks
Nico

I have exactly the same problem,
Did a full update with pacman.
I haven't updated with yaourt, because I had some problems and rebooted, but now I cannot access the terminal.
If I switch to tty1, I constantly switch back. Ctrl+Alt+Backspace is not enabled and I'm not sure it would work.
I've tried to only boot to runlevel 3, but gdm is in the daemons or I did something wrong because I boot into X again.
Anyone have an idea how to solve this?
Thanks
EDIT: solved it for me
Step 1: on boot let GRUB only boot to init 1
Step 2: change config files so not to start X
Step 3: reboot so you have networking support
Step 4: search in aur if you have a your own cairo package (pacman -Qm)
Step 5: rebuilt that cairo package
Step 6: start X
