OpenSUSE Network :: Networkmanager Causing Freeze On Resume?
Jul 23, 2011
i've been able to narrow down a freezing issue on my laptop, down to NetworkManager when i have a cifs share mounted in fstab.removing the cifs mount, or using 'ifup' method appears to fix the issue.the problem is when my laptop resumes from sleep, and when using NetworkManager with cifs share, then i get a 20second freeze when using the launcher while the network sorts itself out. this happens on either wifi or wired connections. this freeze only occurs when using the Launcher for the first time after resume. if i dont use the launcher then everything is fine untill i do (ie: i have network access and desktop shortcuts work fine)

We have an old Zonet 10/100 switch in our home network that locks up whenever there's a power glitch longer than about a microsecond. (OK. It's not that bad but if the lights flicker, I usually end up going down to the basement to see if the switch is hung.) None of the computers or peripherals are affected by the glitches, BTW. Power-cycle the switch and everything starts working again. After putting up with this for months I finally picked up a Netgear 8-port 10/100/1000 switch to replace the Zonet. Unfortunately, when the Netgear switch is in the network, everything slows to a crawl before completely freezing up. Pinging other systems barely worksname would not work.Pinging another system by its IP address worked a little but packet losses of 70%-80% were the best I saw. At first. Then it gets to where the loss is 100%.
All systems were rebooted after the Netgear switch was inserted into the network. The systems that were capable of gigabit connections autosensed the new switch and set their port speed accordingly. And that's about all that works when the Netgear switch is present. (The Zonet is back in the network now.)One thing I have not tried is forcing the port speed on the gigabit-capable systems to 100Mb and re-inserting the Netgear switch into the network to see if the problem if due to running some of the ports at 1000Mb.The systems on the network are running various versions of Linux (with different kernel versions, of course). Most are due for upgrades to get them current but I was planning on hitting the systems that had gigabit-capable ethernet interfaces thinking that a.) 100Mb speeds have been around forever and no problems have been seen when everything was running at 100Mb in the past and b.) the gigabit support for the older kernels should be better (one system only supports an MTA of 1500 max at 1000Mb).

I've been having trouble lately with firefox freezing. For awhile I couldn't figure out what was causing it as it seemed random. But I think I narrowed down the problem to the mplayer plugin. Whenever I go to a site that has streaming video, the mplayer plugin would start reading the stream, but then display "stopped". Now sometimes when it does this firefox would freeze, but sometimes it wouldn't freeze till I start mousing over my bookmark tabs, then it would freeze my entire desktop. I can move my mouse but not much else. I can do a ctrl-alt-backspace to reload the xserver. Has anyone else noticed this? Also, can some help me troubleshoot this. I've removed and then re-installed firefox and the myplayer plugin; deleted my .mozilla directory; changed profiles. Is there anything else I can do?
Here are the package details:
Code:
Repository: @System
Name: MozillaFirefox
Version: 3.6.15-0.2.2
Arch: x86_64

I'm having a few problems with XOrg freezing while playing World of Goo (not the worlds most intense game for graphics, but seemingly too much for my rig). I initially posted on the developer's forums, but they said a full X freeze wouldn't be the game. Testing with BZFlag got me a full Xorg freeze even quicker than with WoG. Later I even tried glxgears to see how well it ran and even that froze the system! My only way of recovering is SysReq-REISUB.
Specs/system details:
2.4GHz Core 2 Duo (E6600)
2GB RAM
Radeon X1950XTX using the open source drivers
openSUSE 11.2 (64-bit - patched up to date and without an xorg.conf)
[code].....
So, is there a fix for the huge instability with 3D graphics, or am I stuck between a rock and a hard place with the options of outdated official drivers that may not work with the latest kernels (and would need manually rebuilding even if they did) or flakey open drivers that are guaranteed to freeze at some point, it is just a matter of when?

There is an intermittent problem with resuming from s2ram. Occasionally, the power button is pressed to resume, the screensaver comes on but the animation is frozen along with the mouse and KB. Sometimes the desktop will show although with the same frozen condition. My swap parition is 2GB. I read in the forums that a small swap partition may cause a somewhat similar condition. I also read a recommendation to disable powersaving and screensaver, again not for my exact symptoms. I would like to find the root cause even if it takes some doing. Otherwise, the system rocks (except Amarok never worked but Kaffeine works for sound). Here are the system specs:
openSUSE 11.3 x86_64
KDE 4.4.4. rel 3
HP xw9400 Workstation AMD 64 Opteron
OCZ Vertex 60GB (dedicated system drive-single boot)

I have a very simple bash script that just runs a series of backups using tar; for example, one of the lines reads:tar -czvpf /srv/backups/backup_home.tar.gz /homeThis script is scheduled to run every Friday, but occasionally I will schedule it to run before using 'at'. The script is located on the same disk as the backups are saved, I then transfer them off the machine manually (I've yet to automate this). I am only compressing files that are located on the server's disk, no files are being transferred over the network at all.
The problem is, occasionally it appears to be causing the 'server' I have running all the time to completely freeze. When this happens the machine does not power down and there are no entries in the log that indicate a problem. Everything simply stops until I press the reset button. Note that this issue also happens when you run the script manually and not just when it is run via cron or at.I *think* this might be happening when a large file is being compressed, but I'm not certain.

I'm experiencing constant system freezes, and was wondering which log file to view in order to determine what is causing it. I switched over from linux mint as it was giving me the same issues now being experience on my debian setup.
When my system does freeze, the keyboard is unresponsive (caps lock won't even turn on) and I have to use the power button to get out of it. The only thing that does work is my wireless mouse which I can still move around.

So I have recently been making attempts at setting up my RTL8192SU chipset usb wifi. After struggling to set it up by following the steps on this link: [URL]../url?sa=t&jUyXQukrfIw After doing this I had no idea what it was supposed to look like but It did display several warnings along the lines of "warning: cast from pointer to integer of different size" I continued following steps as another error occurred "cp cannot stat autoconf.rtl8712_usb_linux.h" I then entered sudo modprobe 8712u and my screen went black i was forced shut down . Upon rebooting I found it also would lock up if my usb device was plugged in It will boot with it unplugged but as soon as it is plugged in again it will lock up my system and send it to a black screen.

I had a google of this but can't find anything useful. I use networkmanager to configure my wireless card. Currently this only works when I'm logged in to KDE. If I log out the system loses the network connection. Is there a way to make it persistent using NetworkManager?

since a few weeks I have a problem connecting to other hosts when I'm using another wireless network, which has a different DNS IP than I have in my network. I have to change /etc/resolv.conf to change the nameserver. Can NetworkManager control the nameserver? If yes, how?

I'm having some trouble hooking my external flatscreen monitor up to my Toshiba Tecra's docking station and having Mint (or Debian) be happy with it. The laptop uses a widescreen monitor but my external is a 4x3; I wonder if this is causing problems. Of course, it may just be the Intel 82801G graphics adapter.et things up properly in the Display Preferences config window (I'm using Gnome, btw) but when I hit apply, the system locks and I have to hard boot. I've never set up a linux box with multiple monitors before, let alone multiple monitors that require different resolutions.

Whilst watching my system boot I see the following error:
'drm: radeon pci probe error kernel requires firmware non-free'.
When I install the ATI graphics driver, sure - I get all the screen resolutions I could possibly want, but the cost appears to be that it makes it causes my system to freeze at the user name and password screen. Sometimes the cursor blinks teasingly, but nothing appears as I type; sometimes the cursor itself is frozen.
My question isn't about the myriad of theoretical key combinations that might work - none of them have thus far.
I'm wondering whether I can simply continue using the default driver that the debian installer (ver. 8 stable 'Jessie') installed on my system. It's true that I only get 3 choices of screen resolution - 1152x864, 1024x768, and 800x600 - but my system seems so much more stable than when I install the proprietary ATI driver.
Aside from the login screen freezing - more often than not, strange things were happening keyboard wise - especially when composing posts for forums - the cursor would suddenly jump to another line of previously composed text for example!
So, can I keep the default driver or is it best to install the ATI driver and attempt to troubleshoot it? Is it even possible to troubleshoot a problematic driver - I knew how to do such things in Windows, but still learning about linux.
Also, when my system freezes at login (for whatever reason), if I'm obliged to simply hit the laptop power button to power down and press it again to restart - is this potentially damaging/corrupting my system - Debian, or indeed my hard drive?
Going forward, is the ATI driver issue likely be addressed in future Debian releases? Obviously, I would prefer to have the proper driver installed so as to have more screen resolution options - since I will be using my laptop for developing and testing web sites.

I am experiencing troubles when connecting to my new private network under Linux (works fine with Windows). I cannot get an ip address and the logs tell me a bit more, but I would like to know how to proceed to resolve this issue. My network adapter is an Intel Wifi Link 5100 using the iwlagn driver. Connecting to other WEP APs usually works flawless, it's the first time my system won't connect at all to this particular WEP encrypted access point.

I seem to have somehow messed up my repositories and now NetworkManager isn't working.
I have two errors happening, which I'm sure are related. First of all, when I try to load knetworkmanager, I get the error:
Code:
knetworkmanager: error while loading shared libraries: libkminterminals.so.4: cannot open shared object file: No such file or directory Second of all, when I restart my computer, upon loading I get a message from Akondi Server Self-Test saying several databases failed. I've never seen this before, so I think fixing these errors would be best? Some of the errors are MySql failed, akondi not registered at dbus, etc.
Lastly, I don't have a wired connection so currently my machine has no internet. I'm using a second laptop to get necessary files and I transfer them with usb.

I find that the new KDE4 notification icon is not very easy to see.The "progress" indication is a microscopic vertical progress bar, that I find very difficult to interpret.OK, it is a minor annoyance, but I do find that I regularly try to use the network on my laptop before the connection has been established.It is also a regression over the icons in 11.1 or before, which were very clear.If people agree with me on this point, I will post a bug, with the aim of getting a clearer icon.

I installed OpenSuse 11.2 LiveCD. I'm currently running patch download and installation so maybe this will fix my problem. When I use NetworkManager, WPA or WPA2 are not an option. I'm give four encryption methods (WEP 40, WEP 128, LEAP and Dynamic 801.x) Is this a problem with my Thinkpad T23's 802.11b wireless card? Do I need to install a patch?

I have a successfully connected VPN connection. When hovering on the networkmanager applet it show beside the wireless connection also the connected VPN. The icon also changed from staircase-bar to staircase-bar with forelock. Oh yeah I'm using GNOME desktop.However when right-clicking on it and choose Connection Information I can only found tab for the wireless connection. How can I have the information tab also for the VPN connection, showing like IP address and gateway used?

I just tested Networkmanager on OpenSuSE 11.2. I tried with my wired connection and it works.
I thought I test to connect with network sharing with my Android phone. The Android phone connects according to Networkmanager, but I'm not sure if it actually works as the wired connection is still active.
I tried to figure out how to disable the wired connection, but eventually gave up and just pulled the wired network plug.
But surely, there must be a way to disable connections from Networkmanager?

On fresh install of 11.4 everything worked fine, but after some updates networkmanager stopped working properly on my netbook (intel atom n270 based).When I log in, network manager shows that networking is disabled and I can't connect. Checking/unchecking the checkbox does nothing. All settings in Yast are OK.To make it work, run "/etc/init.d/network restart" and then plug in the wire OR (in case of wireless connection) I restart network from console, unchecck and check the checkbox in networkmanager and only then it starts to work as it should.

Installed opensuse 11.4 and wireless network started automatically. Then I changed the name of the computer in YAST, and restarted. Now I cannot get NM to start automatically at boot. The red X shows up on the panel app Network Management and settings buttons do not activate the wireless device. I have to start NetworkManager from the command line. After about 30 seconds the wireless hardware symbol turns on and then I can connect to the network.

The good news: 11.4 seems to have much better support for my radeon graphics driver which makes many of my workarounds for 11.3 unnecessary
The bad news: whereas previously for 11.2, 11.3 using traditional ifup meant that I could easily restore internet (either wlan0 or eth0) with ifdown/ifup now this seems to have no effect. I haven't investigated further yet since without internet on hibernate or suspend 11.4 is not my grub of choice at the moment
There seem to be quite a few glitches with the 'stable' release of 11.4 but this seems to be the main problem for me. (Minimizing the beta 4 Firefox windows closing them is another...)

I'm currently struggling with the following problem: Connecting to a wired network with NetworkManager (0.7.1) is no problem at all: Everything is set up automatically, including the default route:
[Code]....
When I now add the route manually it works. But as soon as the cable is plugged in, the NetworkManager overwrites the routing table entry again (which makes it quite annoying). Does anyone know a way to avoid this behaviour?

I've run into a situation where knetworkmanager tells me networking is disabled. If I switch to the ifup method in Yast then I can get online but when I switch back to user controlled knetworkmanager tells me that networking is disabled.I've actually had this happen twice.The first time I somehow managed to get it working again (I thought it was by right clicking on the icon in the system tray). This time I don't see the same option.Has anybody got any suggestions on how to get knetworkmanager working again.

I'm having some trouble with my networkmanager on openSuse 11.2. I want it to get the DNS Server from DHCP, but it notices that I had another process modify it (dhcpcd to be exact) and it just won't overwrite it, resulting in an out of date DNS server to be used.

Just installed OpenSUSE 11.2 and I have to say it feels great.Only gripe I currently have is the NetworkManager that is starting up very slowly. When I have logged into KDE KNetworkManager applet says that NetworkManager is not running and hence I have no network connection. This is fixed if I start NetworkManager (as root) or just wait a couple of minutes. I have one ethernet interface only, no wireless
