SuSE 11.2 = 2.6.31, ntpd 4.2.4p7. My offset and jitter are large compared to what I see on the internet. I have also been trying to use a GPS+PPS but that doesn't seem to matter one way or the other. They usually start out with offset and jitter in the single digits and drift / move to something like -400 and 80 over a couple of hours. I have tried various remedies under ntp.org like HZ=100, setting clocksource to tsc, hpet, or acpi_pm. I do not know what to do with acpi so i didn't test that. One of my systems has drift of < +-20 which is good. I have tried it on another identical system and also an 11.1 system. One of the systems is not behind my firewall. They do not run a firewall themselves or VM or pretty much anything as they are not being used.
I have used ntp.conf with/without 'prefer'. Here is a recent ntpq -p:

Is there something wrong with 11.1 and 11.2 ?
Here is the ntp as run from /etc/init.d/ntp start (also with yast):

I'm having trouble keeping NTP synchronized and able to provide time updates to other devices on the private network. I believe this is because the server has a too large of offset, that causes all NTP clients syncing through the server to fail.
I have two setups, one working, one failing, with mostly identical installation and settings.
Setup A is the working setup, as I will name it, is ubuntu server edition 8.04 with kernel 2.6.33.1. ntpd version is 4.2.4p4.
ntpq -p outputs this information: remote refid st t when poll reach delay offset jitter ================================================== ============================ *europium.canoni 193.79.237.14 2 u 925 1024 377 101.851 0.194 0.328 ntp.conf is:
I seem to have had this problem in kubutu as well, but my screen's image is offset downwards, such that I can barely see the bottom "task bar".I haven't been able to find any resolutions to this problem, except that the refresh rate might be wrong. Unfortunately, the "Display" program only gives me two options -- 60Hz, and Auto
I used K3B to rip some of my DVDs (using the Xvid codec) onto my laptop to take away on holiday with me. This worked fine for 2 of the DVDs but the 3rd one ended up with the audio out of sync with the video. Fortunately VLC comes to the rescue with the ability to offset the video and audio tracks.Is there a way to re-encode the ripped files to permanently fix the offset.
since i did a system update followed by install of akonadi and after a second reboot i'm getting a kernel segmentation fault. i've tried repairing the installed system and i've tried doing a fresh install but all to no avail.
I've notice that cairo dock has jitter when you move the mouse over the Dock. Indeed if you install Gnome Do (Docky) you notice that when you move the mouse over the bar the effect is very smooth. I don't understand why cairo dock is less smooth in movement but i finally found a solution:
1- Close cairo-dock bar;
2- Go to ~/.config/cairo-dock/current_theme/
3- Open the file cairo-dock.conf with gedit
4- Now press ctrl+f and insert in the search: refresh frequency
5- Now you have to modify the line:
#i-[5;60] Refresh frequency when mouving cursor into the dock : #{in Hz. This is to adjust regarding your CPU power.} refresh frequency=35 in thi s way: #i-[5;120] Refresh frequency when mouving cursor into the dock : #{in Hz. This is to adjust regarding your CPU power.} refresh frequency=120
6- save the modification;
7- start cairo-dock;
This is an example of bad programmation, a lot of possibility to configure the dock but no one of this it's adequately cured.
After having used fc5 for years, I installed fc10 in order to be able to run the newest versions of some of my tools. Under fc5, my monitor (Dell 2407FPW) and adapter (ATI Technologies Inc RV380) have happily coexisted at 1920x1200 76Hz. During the fc10 install, the monitor flickered a few times, then settled down (an auto-detect by the installation?) Now, after installation is complete, if I display a window with a lot of small text, the text is nearly unreadable because of horizontal jitter. If I move the window part-way off-screen, so that there is less small text on-screen, the jitter is somewhat reduced.
My hunch was that the installation got the ModeLine settings wrong, but when I went to edit /etc/X11/xorg.conf, I couldn't find it. I also ran a case-insensitive search for any file containing "ModeLine", starting in /etc, but nothing turned up except /etc/prelink.cache, a binary file.
I tried running Computer/SystemSettings/Display, but every time I do this, the monitor immediately goes into sleep mode, and nothing will recover it out except an X11 reboot (Ctrl-Alt-Backspace).
Is there any way to tweak the display settings other than the gui ("Display") program?
I'm getting some jitter when capturing via RCA or S-Video from an em28xx device. Input type is PAL, other than that I haven't fiddled with mplayer or vlc's options (vlc only sees the RCA input, mplayer sees both)
I use Brasero/K3b but both of them showed that the ISO is too large (4.7GB) - while the DVD capacity of the disk I'm using is 4.3 or so GB (Princo). Then I figured I'd try to extract the files and burn them like that (extracted iso being 4.2 GB). So then I encountered another issue, usually one would find boot.catalog, which wasn't the case here. Any ideas on how I should burn my DVD ISO ?
I've been a happy Arch Linux user for years now. Recently, on my eee 1000he (an Atom netbook with intel GMA graphics) I've been seeing strange things. After it has been on for some time (usually hours), the screen starts to jitter, just for a fraction of a second, every now and then. After this has happened some times, the screen goes black (one time it went red). The backlight is still on and I can still ssh to the machine which reacts normal appart from the black screen. I can only regain the screen when rebooting. What could this mean? Is it hardware or software? X logs don't shown anything weird, where should I look? I haven't found anyone with the same problem on the net.
how big and widespaced the fonts on Clementine playlist are and how good they look on the appmenu (where my mouse pointer is). This is not because Clementine is QT4, I've got the same problem with Chrome, Opera etc. I've been messing with system-settings (KDE settings tool) a day before the fonts become that widespaced in order to make my KDE apps look more native on my GNOME, but I haven't touched the fonts settings there.
Problem is with files greater than 4G onto dual layer or BD disks.mkisofs crashes. I believe the problem to be when this requires udf filesystem and disk does not get written to. As yesterday version is suse11.3 patched to date. k3b writes standard dvd disks ok. I am seeing a lot of searches saying this is because of cdrkit rather than cdrtools, can I replace this easily? Is this the case? Tried setting the k3b options when burning to udf same error. Other searches show k3b has fixed probs with these issues, so appears to point to underlying mkisofs stuff full error log in yesterdays post if it helps. I will also try on ubuntu to see if it works there
1. An external hard disk with VFAT32 file system has a continuous 23GB file (old HD disk image). It is too large to 'remove to wastebasket' and unlike MS Windows remove to wastebasket does not sense file size and wipe file index .
I am so sorry but this is not for me. I cant make this work. I want to install windows xp back in my pc, i just give up with Linux, I lack the expertise to do anything here.
I have a problem with burning some disks. I believe the problem to be when the file sizes are large. using suse 11.3 x 64 and updates done. k3b version 2.0.1-1pm 2.7 burned normal dvd yesterday with3.5 Gb + 1.5Gb files. Tried burning to BD-R disk with 11.5 Gb file. I have burned blu ray disks before with my machine but used nero, I would prefer to use k3b as should do this. I get error of mkisofs crashed and following error log
I've got a strange sendmail problem I've never come across before...Messages less that 2500 lines (approx 169kb) are sent correctly - anything else goes straight into the queue and is never delivered. The server sits in a intranet, is not connected to the outside world, and forwards its mail to a smart host.All configuration has been done through yast, so there are no unusual settings. I've run sendmail on SuSE from version 6 upwards, and this is the first time I've come across this - it's driving me potty
i have a problem here whereby some 20 over servers in my network is having regular Offset values. The configured threshold is 55, but whenever it exceeds 55, i have alerts coming in. My questions are;
1)how do i find out what is causing the Offset value to be high?
2)i have workaround in mind, that is to create a cronjob to restart the ntp daily, or hourly - is this workaround an acceptable practice?
My main concern is to find out what is causing the frequent offset spike/increase. real example from my servers:
When I installed opensuse 11.2 64-bit (KDE) the installer set the root partition to 20GB by default. That seemed unnecessarily large, so I reduced it to 16GB. I then completed the install (basically a default KDE install minus games & educational stuff) and still had more than 8GB free. I'm aware that these days hard drive storage space is quite cheap, but it's not so cheap for me as I have an SSD. Would it not be reasonable to reduce the default root partition size to 12GB, or perhaps vary it according to the software package load selected?
Running Opensuse 11.4 (but had same problem on 11.3). During startup and shutdown, the text messages are displayed using a very large font (characters are > 1 cm high). How can I specify the font and font size it uses ? Presumably it is doing a bad job of detecting the monitor (its a Samsung SyncMaster P2250). Which config file contains a suitable entry, and what is the entry ?
I've started having problems with large file downloads. A download will start and after a while freeze. The downloads window reports the correct connection speed and gives an estimated time to complete, but it stays frozen. Small downloads, torrents and surfing are not affected. I can do everything else normally even when the download is frozen. I've checked with my ISP and everything with my equipment checks out.
When accessing an NFS mount for a large (200MB+) file transfer, the transfer starts rapidly, then becomes slower and slower until it hangs. On several occasions, it has frozen the client machine. Both client and server are set to default to nfs version 3. Slowdown and hang also occur when connecting to FreeBSD NFS mounts.
Presumably (I hope), there is some sort of configuration for the client that needs to be set. what should be changed in the configuration? This worked out of the box in OpenSUSE 11.0.
Problem: In Fedora 7 picture offset about 5 mm to righ on screen. I solved this with xvidtune and insert modeline in xorg.conf. In section Monitor..... I'm not sure. Why I can't use this trick in Fedora 12?
For instance, using dd, you create an image of a whole hard drive, all partitions. The script then comes and mounts the partition located at offset 63 (or whatever the user picks).I do not see this option in the mount command.No other searches turned up anything meaningful. So I am bowing to the gurus.
I am using OS 11.0 Every time I boot my laptop (dell inspiron 9300 - ati video M300). I get the desktop display as 1920 X 1200. This is too large for my default. I use KRandRTray to resize back to 1024 X 768. How can I set 1024 X 768 as the default but still have the option to go to 1920 X 1200?
I have a new installation of Karmic 9.10 up and running but for some reason my Nvida Quadro NVS 280 SD graphics card can not align my Sony SDM-HX73 monitor correctly. On the left I'm missing 10 or 15 pixels and on the right I have a thin black strip of unusable screen.
One of the main things I need Nagios to do is check the servers for time drift. I have all my servers running ntp against an NTP server, but I still get some nasty drift on some of the systems. I want Nagios to monitor this drift and inform me when the drift reaches a certain point then I can go in to reset the time on the system. My question is the accuracy of the check_ntp_time function or am I reading it wrong. Running "check_ntp_time -H time01" produces the following output
[Code]....
You can see the offset returned by check_ntp_time is -0.0006129741669 whereas the offset from ntpq -p is -0.292 I don't see a match from the check_ntp_time function, they are not even what I would call close. Am I misunderstanding something or is there a large difference in values between the ntpq command and check_ntp_time function?
I'm looking for a function (prefer POSIX, but Linux specific would do if it has to) to get the current timezone offset. For my location, eastern USA, that should be -14400 when daylight time is in effect, and -18000 otherwise.
I'm using pyqt3 for my app and am lost on even how to attempt this task... On a vinyl cutter to have the blade pivot it must be offset from the center of the shaft it's on so say for example a .25mm offset would leave a .25mm unwanted vinyl attachment when the cutting is done. I somehow have to average or extrapolate that .25mm xy coordinate and add it to the hpgl plot file as a PUx,y; command? I have enclosed a simple sample file that has three images in it. In the corresponding hpgl file everything between the PU commands that are starting with PD are the code for that image (star for eg the pu to move to next image and then all PD for the next image and so on, so once the formula or procedure is figured out it can be applied to as many images there are in the file. Placing the new command at the head of each image PD group. Since there are absolute and relative cutters I enclosed the same exact plot for both types as the coordinates on relative can be negative numbers. Only PU and PD commands and a ";" as a command delimiter as sometimes many commands are on one line.The offset variable will come from a spinbox but .25 is good for an example.
