Suggestion: increase the VM dirty writeback time from 5.00 to 15 seconds with:
Echo 1500 > /proc/sys/vm/dirty_writeback_centisecs
This wakes the disk up less frequently for background VM activity
Q - Quit R - Refresh W - Increase Writeback time
If I wait it decreases to 50000, but it is still huge!
Situation is duplicated after complete F12 re-install. All defaults are used and no changes performed after install. Just checked again and let computer run idle for a while. Powertop reports 79604 wake-up per second, even more than before. Again, the top cause is "pata_atiixp". Also, performing suggestions of powertop shown at the bottom of the program does not help either. That decreases wake-up by a few hundreds only. Wake-ups are still well over 50000.
I installed Fedora 15 twice last night because I thought I had screwed up the installation somehow when I ran a df -h and found that it reported all my LVM partitions twice (/, /home, and /var) and it also showed /var/tmp mounted on the same logical volume that /var was mounted on (lv02 = /var AND lv02=/var/tmp). I've never seen this before and it definitely didn't appear like this in Fedora 14. Is this something new to Fedora 15?
incoming connections are not being reported to my /var/log/secure. I can't see if people are trying to connect. I can't troubleshoot because I can't do anything.
I installed Powertop after reading a number of threads of threads about power consumption issues in Lucid. Though it would be good to know what I was doing. But when I run Powertop it tells me "now ACPI power usage estimate available".
I was reading the forum yesterday, and saw a thread about powertop. Needless to say I tried it on my Toshiba NB305, and thought it might be good to see if I could also get better power usage from my wife's Toshiba A665. The problem is that when I run it on her laptop, it just totally hangs the system, and the caps lock light just sits there blinking. I am not sure why. Is it not designed for x64 systems? Any ideas, or similar problems? I think this laptop has an Intel i5 540M processor, and I am running Ubuntu 10.04x64 kernel version 2.6.32-29-generic.
I have run powertop to see if I can streamline my system but have one problem, the mouse now seems to go into a sleep state if I don't use it for a few seconds. this is VERY annoying and I have to press the mouse button every time to get it to work again. anyone know how I can restore this back to how it was?
Judging by the number of responses (close to zero) to other threads about powertop on this forum, I have little hope in getting any answers. However, I do not know where else could I ask. PowerTop tell me that even after applying almost all the tips and tricks from lesswatts.org, my laptop still consumes over 72 Watts while idling.

Suggestion: Enable USB autosuspend by pressing the U key or adding usbcore.autosuspend=1 to the kernel command line in the grub config This is when I am not touching the laptop. When I am surfing the web or listen to music, it goes up to 2000+ wakeups! How do I cut it further? I am getting like 20-30 minutes max on battery and this is unacceptable cause in Windows I get at least 3 times that.
Was wondering if this is normal. I have a laptop which is about a year old. Recently my battery died (it last 10-15 minutes instead of 3-4 hours as it was before). I ordered a new one. While waiting for the new one I started to investigate power consumers (processes) on my machine. I run slackware64-current. with 2.6.33-rc4-git7 kernel. config - is slightly modified config-generic from -current. I attach t here for any case. Here is the output of powertop:
I am running a Fedora 12 installation in my bedroom as a slave mythtv frontend. I have set it up to be able to put the PC to sleep and wake up with a MCE remote. This has been working for near on a year now with no issues. Yesterday I did a yum update and ended up with kernel 2.6.32.16-141.fc12.i686.PAE (up from 2.6.32.12-115.fc12.i686.PAE)
Now everything seems to work fine however I can put the PC to sleep with the remote but I cannot wake it up with the remote. a cat of /proc/acpi/wakeup shows
At the grub prompt if I select the old kernel 2.6.32.12-115.fc12.i686.PAE then the computer will start up with no graphical prompt (need to figure out how to work kmod-nvidia i guess), but I can use the remote to put the pc to sleep and wake it up again. Also using the old kernel and telneting into the PC I see that /proc/acpi/wakeup is no different. Does anyone have any clues on hoiw to get wakeup to work with this new kernel? Or how do I roll back everything to the older kernel and get my graphics driver back (i tried to reboot with old kernel and then yum erase kmod-nvidia-PAE and then yum install kmod-nvidia-PAE but no luck.
Another thing worth noting is that I can wake the computer with the power button, just not the USB remote. THere is also nothing in the motherboard bios for setting wake on USB.
I been a windows guy forever, and wanted to make the switch. Anyways, I am hoping to do a wireless wake-on-lan from a windows box. I have an older laptop that has a dead screen and I am trying to use it as a server. So, I want to be able to VNC the linux box from my vista machine. I think that's going to be straight forward. But, the linux machine doesn't have a builtin wireless card, so I am using a USB wireless deal. If I let the laptop hibernate/sleep after being idle, can I wake from my vista box over my network?
I've configured my F12 system to go to sleep when idle for a period of time and so far everything has been working out well except that it appears that the USB ports are completely dead with the system is put into sleep. I can't wake it using keyboard or mouse. only with the power button. Anyoen else experience this or know how to allow sleep from keyboard/mouse?
goes to sleep just fine but won't wake up... in Windows, I see that it only supports Sleep Mode S3, which it calls hybrid sleep. I know that the video driver is the key to getting it working properly in Windows, I can get the exact name of the driver if needed but I do know it is nVidia.
I have a feature that keeps me going back to Mac every night, and I was wondering if there was an equivalent. I have a nice app called alarm clock on Mac that plays music from my library on specified days of the week and times AND can wake the computer from sleep to do so. I was wondering if there was a Linux equivalent, such as crontab, that could do all those things. It's the last barrier to almost full time Linux use.
I have a Fedora server at home. I don't want it to be running all the time to reduce the power usage and be more green It only works , whet it is really needed. So when it is not in use (no ssh or http connections have been active for some time), a custom python script suspends it. I have set it to wake up on unicast messages, so when somebody connects to it, the server wakes up.In Fedora 12 everything worked fine: when the server was sleeping and you connected to it using ssh or a web browser, the client waited for couple of seconds until the server was up and then connected (actually it worked even when server was turned off: the command "ssh [user]@[server]" just waited until server was booted up and then connected.)
Now I installed Fedora 13 on the server. When I try to connect to the server when it's sleeping, the client waits for some time (and server wakes up), then the connection just times out. When I try to connect again, it works. When server is up and running, I can connect to it. So when it is sleeping I have to connect twice: first to wake it up and then connect again to log in.Do you have any ideas what is causing this problem, as it is really annoying for me and I don't want to have it running all the day.Also, I have not set up the network in the best way, I think. To start the network at boot, i have put the command
Code:
ifup eth0 to /etc/rc.local.
To start the network when resurming from suspend, I have creted a script with the same command in /usr/lib64/pm-utils/sleep.d. It works, but it does not seam to be the *right* way to do this. Maybe this is also causing the first problem. So how have you managed to get a working network connection on your Fedora 13 headless server?
I have installed fedora13 OS on it recently,earlier it has both windows and linux but now only fedora13. My laptop's harddisk has probably some bad sectors and a software package "Automatic Bug Reporting Tool" has reported kernel crash,gnome-panel crash. I reported them upto some extent but in totality all I can't report. How to deal with it, why is it happening, and will it be harmful for any part like CPU,RAM,HardDisk of my laptop?
I have two problems. I installed a RHEL variant (scientific linux) on an already dual boot system with ubuntu and vista.
It replaced GRUB with (I think an older) GRUB version and to add to that I cannot see my ubuntu ditro anymore. is there a way of reinstalling the GRUB that came with ubuntu then adding the RHEL distro to it?
my second problem is that I cannot figure out how to enable wake on lan in scientific linux (RHEL). on ubuntu I would just write a small script and update all runlevels to run it at startup. what is the alternative on redhat?
I have noticed this now for the 125 time that when you mount a volume and use mount to see if it is ro or rw, it says rw, but actually is read only.
Why is mount reporting it wrong?
systema3:/vol/mysql_vo2 on /mnt/mysql2 type nfs (rw,addr=192.168.10.82)
vs
failed to change ownership of `/mnt/mysql2/.snapshot/hourly.5/v240-2-bin.058' to mysql:mysql chown: changing ownership of `/mnt/mysql2/.snapshot/hourly.5': Read-only file system
I was struggling to find the information so I thought it would be easier to ask here. What does the load average as reported by top mean ? To me those are 3 mysterious values, which most likely refer to some average CPU usage and this is all I know about it (not sure if it's true).What is the maximum value for this parameter (I guess the minimum is 0.00) and what does it mean ?
Today, someone who had problems with his usb flash drive showed it to me. I plugged it in my linux box.
Code: cat /proc/partitions only showed Code: sdb
and no partition name (sdb1, etc.). So I ran fdisk on it I deleted all the partitions (4 in all) and recreated a single partition taking up the whole drive and marked it as c (win32 vfat) I exited fdisk (w) and formatted the new partition
I inherited a centos 5.2 server at my work. I didn't know anything about it when I got it except that the fate of the organization rested on my ability to manage it. I've gotten along fine with it. I don't really like it, but it mostly works. I learned a lot in the process. Anyway, I went bought some more ram for the box because, hey, it's a server and it will serve faster with more RAM. So it had 3x512mb and I took out one of the 512mb and put in 2x1gb (it's only got four slots). I rebooted and and top reports 1585152k of ram. It should be 3gb. So I haul out a monitor and keyboard because I want to see if the BIOS sees more. Sure enough, on boot I arrive at a grub/centos boot screen and it says somewhere that I have 3gb, I boot and top still reports 1585152k.
How do I make this computer realize it has more RAM?
I'm doing an distro upgrade from 11.2 to 11.3 and for the DVD drive, the repo URL comes up as dvd:/// in ast and zypper. However medium not read is being reported, forcing me to find out exactly what "dvd:///" is pointing to.
My DVD drive is certainly readable and mountable and sits at /dev/dvd (symlink for /dev/sr0). I usually mount it manually, but the problem here is I don't know how to find out what "dvd:///" represents.
When I setup Intrepid (upgraded to Jaunty now), I chose to create a swap partition. I don't remember the size I specified. Here's what I'm confused about When I do 'cat /proc/meminfo' or 'free' or use the system monitor, it reports my swap size as 1262304 KB (i.e. 1.2GB). But if I do a 'fdisk -l', the partition size is reported as 746991 blocks (of 1024 bytes) and if I use the partition editor it says it's 729.48MB. XP disk mgmt shows it as app. 700MB too
Currently I am running Ubuntu on my laptop however my desktop is still XP pro. I want to move from XP to a Linux (Ubuntu) or Unix distro (BSD). My desktop is used as my ftp server, music/network storage, and for syncing my iPod with iTunes. The only thing that is keeping me from totally reinstalling the OS on that computer is iTunes. I know there are tons of applications out there that will sync your music to your iPod however I want to still be able to use itunesu and some other features in iTunes. My plan is to run a *nix os but have xp running in virtual box for iTunes. Has anyone else done this and if you have is it a huge pain? Is there a better way to go about what I'm trying to do? I have tried to get the newer iTunes installers to work with wine but I haven't gotten it to work yet. I get errors and the errors are reported bugs on winehq.
My MP3 Player (Zen:Vision:M) has roughly 60 GB of space and yet Ubuntu insists only 3.6 GB is available. I know this is not true because in Windows the correct amount of room is displayed and can be filled up. Because my music collection is stored in my Linux partition I need to solve this issue if I'm going to actually use my MP3 Player. What is also interesting is the fact that the device doesn't show up in Gparted, System Monitor or fdisk.
When I attempt to look at the Zen's contents through Nautilus I get this message:
Error initializing camera: -1: Unspecified error
And when I update through Banshee every song gives an error of:
I am running CPU tests on a radio controller to determine max simultanious calls. A tool using top was developed so that we could get a good look at what exactly was happening on the process level, however we are mainly interested in one object running on the box.The box has a single core Celeron processsor running the Wind River Linux platform. The CPU usage from my object is frequently spiking over 100%. Doing some research online so far has led me to the fact that a multicore processor can do this however I have found no mention of a single core processor displaying this behavior.
I am having a strange problem on my private nameservers registered with godaddy. There are around 10 domains right now which are using my nameservers ns1 & ns2. After the setup of my nameservers, domains. I checked that the domains are resolving good to the mentioned IP addresses which I mentioned in the zone files but when I am checking the domains on it is showing "Missing nameservers reported by parent" error. I don't know why it is reporting me this error.For example I checked one of my domains spurstone.com & I got the above mentioned error. Although whois database is giving correct results with nameservers NS1.INDEPENDENTADVISORONLINE.COM & NS2.INDEPENDENTADVISORONLINE.COM
