how do you enter into different modes of vmstat e.g-disk mode,disk partition mode and slab mode.going through man pages i figured out using "vmstat -p <partition> is for 'disk partition mode'.there is no info regarding diskmode and slab mode
View 1 RepliesI am trying to determine CPU usage on a radio controller running Linux. We have a script that another member of my work wrote using vmstat which I could not get any consistant results from. So, in an effort to understand what was going on I wrote a script using ps. Sadley after running several tests using both scripts, they do no match up at all, vmstat always gives me a much higher value. However, if I simply run the commands at any given time they do match up, therefore I believe that there is an error in one of the scripts. I am very new to linux and so Here is the vmstat script:
#!/bin/bash
declare -i total
declare -i tries

I m trying to store the output of vmstat 1 10 into a database.I have done the necessary homework to connect bash to interact with the database.Program logic.1)storing the output of vmstat 1 10 to a file named abc.txt2)I m applying a filter to vmstat to get desired output containing cpu(user),cpu(system),cpu(idle) values.3)
Code:
# cat abc.txt | grep -vE '(procs|free)'| awk '{print $13 " "$14 " " $15}'

I am analyzing memory usage on a Linux system. When I run vmstat -s, I see the following:
waffleman@waffle-iron:~$ vmstat -s
3549184 K total memory
3206708 K used memory
1918012 K active memory
1037320 K inactive memory
342476 K free memory
[Code]...
I know the system has 4096 MB of RAM installed, but why does it show only 3466 MB? Can this be interpreted as total "available" memory? Perhaps the missing 630 MB is being used by the kernel and cannot paged out?
I also tried this on on an Embedded Linux system and saw a similar result. The DRAM chip has 128 MB, but only 124 MB shows up in vmstat.
Simple question (I hope). What does the dot at the end mean?drwxrwxr-x
View 3 Replies View RelatedJust installed Ubuntu 10.04 via Wubi on my laptop. It's looking good so far but to cut to the chase, I only have 2 display modes. This is 640x480 and 800x600. Is there anyway to 'trick' the system into getting a 1200x800 display mode as I have found that graphic drivers for the SIS Mirage 3 are non-existent.
View 6 Replies View RelatedI am running a mainframe emulator on an old HP server in runlevel 3 text only. I have googled a bit but found no information on controlling the text video mode in runlevel 3. When I boot my Fedora 12 system chooses the highest resolution it can meaning my c3270 terminal emulator program (80x25) is in tiny font occupying a fraction of the upper left corner of the screen. I have looked everywhere but can find no mode setting commands for runlevel 3 text only.

View 3 Replies View RelatedI'm on Debian Squeeze, my PC has a Radeon HD4770 card. I honestly don't know if it's currently running on OS or proprietary fglrx drivers; I installed fglrx, but the control panel app insists the driver isn't loaded. I'm following these instructions to try to get my screen running at 1280x960x85. It's currently at 1280x1024x85, but it's an old CRT that, for some reason, works fine at 1280x960 but gets unfocused at 1280x1024. I'm following the step "adding undetected resolutions", and here's the result:
Code:
fallingwater@longcat:~$ xrandr
Screen 0: minimum 320 x 200, current 1280 x 1024, maximum 2048 x 2048

I can run xrandr and I get the various modes thatwill supposedly work with my monitor.Then, I run xrandr -s 800x600 and the command tells me thathat mode is unavailable, even though it claims that it is in xrandr -s.What on earth does that mean, then?
View 4 Replies View RelatedI use 3 computers attached to a kvm switch (not the hypervisor) and this works fine w/ windows xp and ubuntu 9.04 and earlier. However I am having a problem w/ Fedora 12. It seems that it cannot read the EDID block, so I am not able to set the display above 800x600. There is no xorg.conf file, so I had one generated by Xorg -configure :1. I also tried using the modeline instructions, but the Xserver would not start until I removed modeline. I have tried adding to Section "Screen"
Subsection "Display"
Modes "1280x800"
EndSubSection
but it seems that this is ignored. how can I get the Xserver to set display modes above 800x600 when it cannot read EDID (thru a kvm switch) and it seems to be ignoring settings in xorg.conf?

View 4 Replies View RelatedI had a problem with the old good ascii/binary FTP transfer modes. I transferred some files (SQL scripting files, in which carriage returns DO matter) using FTP from a windows system to a linux system using filezilla "auto" mode, that should have resulted in ASCII mode for my sql files. These files are well formed and identical to the originals.
Then, someone else picked these files and moved them to another ftp server. I finally found that all <CR><LF> couples have been transformed in <CR><CR><LF>. I guessed that the problem was in the ASCII transfer mode - but, how comes that <CR><LF> => <CR><CR><LF>? I would have rather expected <CR><LF> to become <CR>.
emacs has these 2 mode for spell checking.

I have 4 NICs and am trying to create 2 bonds. The first bond is mode 1, the second is mode 4. What happens though is makes both bonds mode 1. Here's my modeprobe.conf:
alias bond0 bonding
options bond0 miimon=80 mode=1
alias bond1 bonding
options bond1 miimon=100 mode=4 lacp_rate=1
Is there a way I can specify at what percentage i can make my battery to start charging? I guess the default it 95% which ends up wasting a lot of battery cycles.And my second question being can i have different modes like power saver,performance?

View 8 Replies View RelatedSwitching to and from insert mode in Vim is no longer instantaneous since I use tmux. After pressing Esc in insert mode, it takes a noticeable amount of time to actually get out of insert mode. After pressing Esc and any other key afterwards the switch is immediate, and the command for the key pressed after Esc is executed. Any idea what might cause this?The Vim configuration is not the problem as the delay does not occur when I run Vim outside tmux, so this is probably related to tmux somehow. I use gnome-terminal btw.
Also worth noting, it seems I can not define key bindings in tmux for Esc, my plan was to bind Esc to:bind Escape send-keys.Alas, it seems binding anything to Esc for tmux does not work. The same problem occurs in screen as well.

What should look like X Window System (X.Org) modeline to be put in xorg.conf, for high resolution (incuding recommended 1680x1050 @ 50Hz resolution) for 22" NEC LCD 22WV monitor? X.Org autodetect correctly only 800x600 and lower resolution SVGA modes,unfortunately.1,2
How can I generate proper "Modeline" line for xorg.conf? Is information included in NEC_Datasheet_LCD22WV-english.pdf enough (found on NEC LCD 22WV product info page)? What tools there are available to generate proper modeline for a LCD monitor for Linux? MS Windows (MS Windows XP Home) correctly detects and use 1680x1050 resolution; can I somehow get modeline information from MS Windows?
Footnotes:
1) It might be hardware problem with the monitor itself, as the same LiveCD Linux distribution that couldn't autodetect recommended 1680x1050 mode for NEC LCD 22WV monitor, correctly autodetects recommended 1440x900 mode for slightly smaller NEC LCD 19WV monitor from the same family, by the same producent.
2) Or it might be problem with graphics card (NVIDIA Riva TNT2 M64) not supporting such resolution, or with graphics driver not supporting such resolution.
After purchasing few wifi-usb-dongles for my jaunty and lost many hours, i had no success in bringing them to operate as master or ad-hoc.The devices were Belkin, Level1, and a TP-Link 620 Though the Belkin could work as ad-hoc, but very often disconnects due to buffers issue (though I couldn't build the zd1211b driver for jaunty and it seems that no one can really help with that).
Now I would like to consult with you ahead regarding new potential devices, whether you know it operates as master mode or ad-hoc mode under jaunty (9.04)?
My concerns are regarding:
1. Edimax EW-7318UG
2. Edimax EW-7318USg
3. Edimax EW-7711UMN

5. Edimax EW-7311USN

I tried to install OpenSuse 11.3 on my brand new pc, which already had Windows 7 proffessional in it, and I went step by step through the installation without changing anything. It didn't work. I tried for a second time and this error message kept popping up: "Creating device modes with udev 2.0436224] [drm: i915_diver_load]*ERROR*Detected broken BIOS with 262140/2644kb of video memory stolen. 2.0436224] [drm: i915_diver_load]*ERROR*Disabling GEM(try reducing stolen memory or updating the BIOS to fix)"
And then a lot of letters and numbers wich make no sense to me. Now the only way I can initiate OpenSuse is with the OSuse boot dvd and on failsafe mode.
