I have Etch running in my laptop. I found that if the laptop is only running on battery, the disk seems to performs slower than if I running on a power adapter. How do I possibly check the setting and fix it?
I'm the only user on the system most of the time and I keep it as minimal as possible so it's not other services and programs keeping the disk busy.
Is there any way to allow normal fsck boot-time checks when running on battery power? After looking around, the only solution I've seen is to manually alter the /etc/init.d/checkfs.sh and /etc/init.d/checkroot.sh files and remove the AC power check. There must be a better way than that surely?

View 2 Replies View RelatedIm experiencing a strange problem with 10.04. When it first boots up its reasonably quick (as snappy as Gnome ever has been) but after its been running for a day or two it gets ununsably slow and has to be rebooted.
I dont see how it can be anything to do with my hardware as it runs OK when first started. Ive monitored RAM usage and it doesnt seem to differ much. There's always the same amount unused.
My system decided to crash on me, hard. It was humming along happily for about 2 months and now doesn't boot. If I boot from hard-disk, I get grub. Launching the first kernel choice hangs. I thought maybe the install was corrupt, so I booted from usb install disk. The usb hdd didn't boot; something about an error trying to access /dev/sda . Unplugging the internal disk and plugging in the usb install disk does result in the system booting. Plugging in the internal disk in a running system usb-booted system does not result in the system detecting the disk.
How do I know if the disk is physically broken? This seems unlikely since it does manage to launch grub consistently. Or is this still possible? How can I try to mount whatever is left? The usb install disk doesn't even list the /dev/sd*. Any pointers on how to reformat the drive if it's not being mounted?

It worked well in Lenny, but it doesn't work in Squeeze:

I have Ubuntu 10.04 LTS just installed on my IDE 41Gb HDD. After installation, I plugged in a SATA 320 Gb HDD. I ran gparted, I partitioned the HDD in 3. It was recognized as sda1... I could see the 3 partitions in my "Places" renamed as I wanted, could see my IDE HDD and my external 1TB HDD. But after one day, computer was not turned off, I come back to it and... couldn't see what I previously had done (my 3 partitions on SATA just vanished?). I reset the PC and go in BIOS - nothing there. Turn off PC, reboot>BIOS> HDD SATA 2 recognized. Press F10 save, Ubuntu is up, but still no SATA hard disk. I go to gparted... no option with SATA. What can I do to have it back? I didn't mount anything since during partition I didn't have this option. This is what shows up now: (the 41 Gb HDD is now sda, before was sdb - I guess because it is smaller?)

I want to use my 2nd internal HDD for non-linux software and photos, videos, music (so a second storage).
I am doing backups and restores to and from a backup server machine in the garage (in case of fire or theft) using rsync, and the LAN is running much slower than I think it should. Best consistent speed I get is 40Mb/s. The lights on the interface cards indicate it's in Gb mode, and the interfaces are fairly new. The router is a Netgear WNDR3700 the top-of-the-line consumer-grade router. Hardwire only, using Ubiquiti ToughCable and ToughConnectors, less than a 50' run.
View 12 Replies View Relatedgetting back to our laptop, the stability window is ~3.2V. Meaning that when you operate the battery above this the electrolyte is oxidized on the positive electrode and reduced on the negative electrode. Remember that we only want to oxidize and reduce the active materials and don't want to do anything else. All these reactions other than the ones we want are called side reactions and these are really bad for the battery. The nominal voltage of a laptop battery is 3.7 V which means that something bad wants to happen as we use the battery.So long story short, stuff (e.g., passive layers and poor kinetics of reactions) happens and things are not as bad as they seem and you can increase the voltage up to 4.2V without bad things really happening. All chargers for Li-ion cells today cut the battery off when it reaches 4.2V. What you have to realize is that at 4.2V, these side reactions are present in finite amounts and start to chemically kill the battery, but its not that dramatic.
Operating to 4.1V makes things better and extends the life, 4.0 V is even better and so on. So why don't battery manufacturers cut the voltage off at, say, 4 V to get better battery life? Because every time you cut this voltage down you decrease the capacity of the battery and its run time. The 4.2V cutoff is a compromise between good run time and decent (read "not pathetic) life.On the other hand, if you charge the battery and then pull the plug (so to speak), the battery discharges some, the voltage drops, and these reactions become less of a problem and your battery life goes up. So the best things you can do is to charge the laptop (or cell phone, camera etc.) and once its charged, pull the plug. Your battery will thank you for it.As a matter of fact, if you own a Lenovo Thinkpad, you can actually change the state of charge to which you charge the battery using the Battery Maintenance utility. You can change this from charging to 100% state (where the voltage is 4.2V) to 90% so that your voltage is less. You lose some energy is doing that, but atleast you can change it to 100% when you need battery power and put it back down to 90% when you can plug in. I wish my Mac has the same feature.
I typically use the battery for a while (say 1/2 hour to 1 hour), then plug it in and wait to fully charge it, then I pull the plug and use it again for 1/2 hour to 1h and then I repeat this. Takes some getting used to and I forget to do this, but I try.
i currently try to mount 4 internal sata disks using hal on a server installation?
i did
apt-get install hal and copied a .fdi script to /usr/share/hal/fdi/policy/10osvendor/30-storage-all.fdi
as far is i understand now i need a hal/dbus client
gnome-volumen-manager seems to be one
apt-get install gnome-volume-manager
now im stuck there is no such executable like gnome-volumen-manager thus, how does it work? how can i start it? how do i know if and why the .fdi script works or fails?
since its a server edition and its purpose should be a very minimized server install i dont want a GUI like gnome fully installed

I wonder what are models and makes of good internal SATA or IDE DVD-CD burners. I'd like to get one for my desktop tower since I've only had CD burners before. For burning, I use k3b and I'd be doing more CD burning than DVD burning but would also use the burner to watch a DVD movie now and then.
I'd prefer one that isn't too fussy about media. In other words, I'd be happy to have one that takes and plays nicely with commonly found media, rather than with exotic, hard-to-find media. And a burner that handles a good range of the various DVD formats would be nice too.
I don't need LightScribe because I figure it will only work for Windows users. Yes or No? [But does Linux have some package that lets this LightScribing work?]
[My OS is MEPIS 8.5, a Debian-based OS which uses Synaptic for package downloading and installation.] Tell me what good luck you've had with burner and tell what makes/models to avoid.
I am comparing distros of Linux on a computer with VERY low specs. I have a CLI only version of Ubuntu 9.10 running A-OK, but when I run lwm or just X the video flickers (which I believe is due not to the video card/driver but to the resources used). I have tried this with two video cards with the same result.
When I run puppy it flies with no setup.
I know that Puppy is designed for older systems (2.4 Kernel and all that), but is there any other reason why Ubuntu would be slow in comparison.
I am using the nv driver with a Riva TNT PCI Video card.
I am running openSuse 11.2 (32-bit), my CPU only supports 32-bits. I have a hardware RAID device. My system has 4GB of RAM. When I configure my system to only use 3GB, 2GB, or even 1GB, using mem=1024M in grub, my RAID performance is much better then when letting my system use the default 4GB available.Can anyone explain to me why this is? Is there anything I can do, i.e. kernel configuration, that will help performance when running with all 4GB enabled?

I've got an Addonics AEIDDSAU multi-flash reader/writer that uses the SATA port LINK. I'm running XUbuntu 10.04, 64 bit on an Intel DQ45CB motherboard. The board has 5 internal SATA-300 ports and one external eSATA-300 port. The Addonics reader works fine on the eSATA port, but it doesn't work (properly) on an internal SATA port. By "doesn't work properly" I mean that when connected to the eSATA port, plugging in a memory card causes an immediate detection and the contents of the card pop up in a window (as they should).
When connected to an INTERNAL SATA port, a plugged in card does not show, and using CFDISK to look at the "drive" shows an unformatted 64MiB disk that really doesn't exist. Being an INTERNAL device, the Addonics reader is rather worthless if it doesn't work on an INTERNAL port, and there's no clean way to bring the eSATA port inside the computer. By the way, I'm sure this is NOT a "Linux" problem because the reader behaves the same way in Windows XP.
I've found myself using the -v flag for lots of applications less and less (especially for trivial stuff like tar and cp). However, when I did and I was, say, unzipping a large file, it would take longer than when I didn't use the -v flag.I assume this is because the terminal has to process the text and I'm filling up whatever buffer it might have. But my question is, does this make the application actually run slower or does it complete in the same amount of time and what I'm seeing is the terminal trying to catch up?

I have not other browsers on windows; on linux there is aroraonqueror (KDE3), kazehakase, chrome, and dillo, besides text browsers. I didn't test on dillo; Kazehakase and chrome were the only ones which had nearly decent results, but still very bad, 11 to 13 seconds for chrome, and 21 for kazehakase. Konqueror just seemed to never finish to load the page, I gave up when it was still loading somethingfter nutes and 5 seconds.'ve emptied the cache every time I would test, and I was running almost only the browsers and not much else.

I've researched a little bit about, but not enough to make a list of possible things to change in order to improve the speed on linux. Most of the time there are people just agreeing that on windows the rendering is faster, and other people saying that with them is the opposite, with some minor variations like people saying that linux is faster for plain downloads while windows is faster for web browsing due to better graphics.

View 7 Replies View RelatedI am using OpenSuse 11.2 (64 bits) with KDE 4.3.1. My hard disk partition contains 3 areas : / + /home + swap. Frequently the / area is filling with, I suppose, temporary files until it is full (15 Go) and that in a very short time, typically about 5 mn. Then, these files are cleaned by the system, when disk space is needed I suppose. The point is that during this time, the system goes slower and slower until the "cleaning". That seems to occur only when Firefox (3.5.6) is running so I suppose that these files are temporary internet files.

I had a dual boot (windows 7 + debian), both of them installed in my internal hard disk, with the GRUB in it. I have recently installed a second linux distro (mint), but I put it in an external hard disk. Now the GRUB allows me to boot any of the three operating systems, but I need the external disk to do it. It seems that after the mint installation the GRUB is now working from the external disk (if the external disk is not connected, the machine does not boot.) �Is there a way to change the location of the GRUB, to the internal hard disk of my laptop?

I have a SSD Harddisk with both an usb and Sata connection, and I want to be able to boot both from usb and sata but I can't make it work. When the disk is connected with sata anything works fine but when I connect it with usb instead, Fedora seems to boot but then it gives me an "No root device found" error and just sleep forever. This happens even if I install fedora 13 while the disk is connected with usb. I am running Fedora Core 13. I changed my fstab to
/dev/sda2 / ext4 defaults 1 1
And the disk is still booting when connected to the sata controller. So far so good. But if I boot from the usb connection, it still give me the same "No root device found" message. Even more odd is it that if I boot my fedora core 13 dvd, and choose "rescue installed system" it can't detect the harddisk when connected to usb. And there is no /dev/sd* or anything similarly which could look like a blockdevice. Did redhat forget to include usb drivers in their rescue image for Fedora core? I just tried the disk on an other system, with exactly the same problems.
I have now added the LABEL=myroot line to fstab(I guess it have to be uppercase to work) and the harddisk still boot fine when using sata, but it still can't boot using usb. I begin to guess that redhat forgot some usb drivers In fedora Core 13, because the system can't see the harddisk when booting the dvd and entering rescue mode. blkid don't show any harddisks at all and there are no block devices in /dev/ which might be my usb disk. Is it possible to find the uuid of partitions if id add the usb harddisk to a windows computer, and more important: will this be the same uuid as linux will se.
