OpenSUSE Hardware :: USB Randomly Disconnects
Oct 8, 2010
I'm not sure if this started with the 2.6.34.4 or 2.6.34.7 update, but one of those.At random intervals the USB subsystem disconnects. When that happens the monitor screen goes black (no input signal) and then returns 1 - 2 seconds later. This was happening every once every 1 - 2 days; today the count is 10 times. It's gotten really annoying.There is a topic about USB mouse and keyboard becoming unavailable due to recent kernel updates. That is not the issue here; I have tried disabling USB auto-suspend with no observable change in behavior.Or could it be that I have a defective mouse?

I have a hp dv3 2110eg laptop with OpenSuse 11.1 (KDE 3.5.10) and Windows 7 dual boot. My wireless disconnects and connects automatically at random intervals. I do not observe this behaviour when operating my laptop under Windows 7. Following some suggestions given in this forum , I uninstalled networkmanager and installed wicd. However, this does not seem to solve the problem. Given below are the relevant information.

I just upgraded from 10.10 to 11.04 but other than that the most annoying thing I've found is that my wifi will randomly disconnect from the network...like it will say its still connected but pages wont load and all my torrents just stop, and then I have to manually disconnect from the network and then reconnect and it works for about a min and then happens again. I couldn't even get enough internet to post this from my laptop so I had to post this at school from a windows. Idk whats going on but it sucks because I cant really use the comp without the internet..

After upgrade to Lucid I have experienced intermittent wireless disruptions. The wireless just cuts out and reconnects.And I was hoping to continue or follow up on the same thread however with the released version.I tried replacing network manager with wicd and I tried the other driver options both without success.I'm currently using the Broadcom B43 driver, when I tried the Broadcom STA driver wireless would not work. I use the 64 bit OS, and this problem did not appear prior to the upgrade.

Hey all, I have got this strange problem with my Slackware server acting as router and gateway to my internal network. It randomly disconnects the WAN connection after X days ( it is between 2-7 days ). This error messages occured in /var/log/messages just before it lost its WAN connection:
Feb 20 14:36:00 tml dhcpcd: eth1: failed to renew, attempting to rebind

I'm having a problem with my wireless connection. When it runs, it's perfect, but every once in a while (and increasingly more often) it randomly disconnects and doesn't reconnect when I click reconnect, even if I manually disconnect it. Every time this happens, I have to reboot the system, after which it works perfectly. Then it dies again.
I've checked around the forums, there are some similar threads but they seem to be specific to the wireless card. The reboot method works, but I'd really like to find a way to solve the problem without having to resolve to the Vulcan nerve pinch. I'm a real newbie to Linux and the more complex side of computers in general, and I hardly know what is what, so please excuse me if I seem a bit thick.

I have an Ubuntu 11.04 Server set up for my small office whose sole job is to run as a samba file server. The problem is that it randomly hangs. For example, I can connect the clients just fine, however if left idle it tends to take a few moments to work when you try to go back into the shared folder or drive. The client will behave like it is disconnected and is trying to search for the drive only to a few moments later, go right back to normal behavior.
If I ping this server while this is happening my requests will time out for a little while and then just start working. The same thing happens when I try to connect with Putty or through WebMin. One second its unreachable then the next its fine.I have already tried swapping out patch cables (which actually seemed to work for about 2 weeks) and I have patched it to an alternate port on the switch. The only thing I have not done at this time is to change the NIC.All the clients are running Win7 with the exception of two XP machines.Simply put, its like the machine just goes dormant for a while until you ping at it for a while to wake it back up.

When I first turn it on to the desktop, it automatically connects and disconnects automatically 5 times then sometimes it would disconnect a few times randomly out of the blue.
This ia an external single usb wireless adapter you plug in the usb port on my desktop tower.

I'm running openSUSE 11.1, with KDE 4.3.00. My Kopete, version 0.70.90, disconnects and reconnects to my jabber server several times a minute.
The jabber server, running the latest version of Openfire, is on the same gigabit subnet as the openSUSE machine in question. I can successfully connect to other IM services (MSN, Yahoo, etc) with no trouble. I also have no trouble with any other network service, from NFS to IMAP. I have other (Windows / Miranda IM) clients connecting to this same jabber server, all without trouble.
It drives me nuts, and it drives everyone else on my buddy list nuts too, as they see constant offline/online notifications for my user.

It's a bit unnerving.The monitor suddenly goes black, the keyboard resets, the mouse resets. And after about 2 - 3 seconds all is back to normal.My USB setup is a bit complicated (mostly because I could). A 7 port hub is connected to a USB port on the computer. Among other things, the 7 port hub is connected to a four port hub on the monitor (Viewsonic). The mouse is connected to the 4 port hub. The PS1 keyboard is connected to the PS1-to-USB convertor which is connected to the 4 port hub.

I am trying to run VNC server on a standard OpenSUSE 11.2 Gnome Desktop installation.I have done this succesfully with SLES for sometime, however, my experience with OpenSUSE 11.2 is that it doesn't work out of the box!!
I am using XP Pro VNC viewer Free Edition 4.1.2 to connect.
I have removed "localhost" from the # special IPv6 addresses in hosts. This fixes the black screen issue for me. All appears well until I disconnect and retry the connection after 5 minutes or so. Then VNC client makes the connection and then immediately disconnects. It's a no go from then on. If I reboot OpenSUSE 11.2 it works again but then reconnect fails again after the same period of time.
I am trying NX now as an alternative. However, I would much prefer to use VNC.

While in Internet my connection seem to be off after some time when I stop browsing. I connect via DSL modem and I turned off network manager control over my DSL connection. I set up my connection on boot. Where can I fix it? Or where can I see the conf files for network connection setup?

i just installed open suse 11.3 after using linux mint 7(based on ubuntu 9.04).i am currently using two internet connections at home, the first is a vodafone mobile modem, which is workind excellent, and the other is a LAN network, that on windows uses a *.exe program to run. i managed to make all the IP, NETMASK, DNS settings and the internet connected, but without the .exe program it just disconnects after 10 minutes.this is the same thing that happens with the connections on windows if i start the computer and not run the "net.exe" program, but if that program is running the internet connections works just fine. i tried using wine to run net.exe, but it just gives an error message.

I have a embedded computer running 10.3 (stuck with that version) that has USB device issues. In reality, it has two USB devices attached, both FTDI FT232 USB to Serial Uart driven hardware. Both usually are at /dev/ttyUSB0 and 1 when everything goes right. The latest FTDI driver is already in the kernel. Randomly however, when it boots one or both will be missing in dev. If we only leave one physically attached before booting, sometimes it comes up ok, the other times there's no listing in /dev/ or lsusb. But when we do run lsusb once and watch the system log, suddenly the device is found and 'attached'. Then it works fine.
I've repeated this with another test USB device (and old cell phone that gets installed as a ceullar modem) and the same thing can happen. It will randomlyy be missing from lsusb listing till lsusb is run once. IE, run it once, no listing, run it again, then it shows up and the system log saya it was just attached. If we leave both, sometimes one device (Call this one A) is ready to go, but device B is missing. If we unplug B, A dissapears from /dev/ and the system log says A was unpluged. The when we reattach B, both show up in /dev/ and the system log reports two USB devices were attached. running lsusb doesn't fix one or both missing when they are both physically attached.

My machine seems to randomly hang, and I am not sure how to work out what is causing it. Are there some logs I can examine that may help me first that I can look at?
My mouse stops, keyboard stops and cpu monitor on screen doesn't move so no idea if its some kind of X thing, os thing, or hardware.

I installed open suse 11.2 yesterday stock Education edition DVD.
I changed the keyboard because it was generating garbage instead of english chars. (everything was stock from the CD)
The replacement kb is a newer one (I favor the old kb's).
eventually the language and layout of the keyboard changes - usually to Arabic or some Eastern alphabet.
I was really starting to like open suse, but if this persists it is unusable.
Something is misbehaving - any Ideas would be appreciated.
I'm running the default desktop env - gnome.

I just installed openSUSE 11.2 KDE via LiveCD on my desktop computer and have been loving it. The problem is that it will randomly freeze and requires a restart. I've tried booting up in safe-mode, but it still does it. Also, when it does, the screen flickers and flashes in and out before it freezes. And before anyone asks, yes, I have my NVIDIA drivers.

We are experiencing a rather odd issue with SSH access to our opensuse linux server. When accessing it via SSH on the local network everything works fine and there are no issues. However, when accessing it via SSH from an external location it hangs randomly. We can log in without issue and some commands seem to work ok. If we attempt to run a command such as "top" the SSH session simply hangs permanently. using "strace" the process hangs at different points so it is not a particular part of it's execution that appears to be the problem.

Opensuse 11.4 gnome/fglrx/compiz Something strange happens when I launch yast2, the controlpanel appears invisible. Meaning that if I ramdomly click around the desktop, the relevant yast modules will start. But I cannot see the controlpanel at all, alt-tab does nothing to remove it, it just stays on top of everything.

My pc freezes when firefox is running not only to open a new tab but also to browse some pictures and flash video. The screen freezes, no Keyboard response. Only mouse pointer can be moved but it cannot execute any program. That means I can see the mouse pointer moves but it cannot click on any icon. I have to ssh from my laptop to my PC and kill firefox process but can't get any improvement. The screen is still freezing. Then I have no choice but to use root right to restart the pc. This system freezing has happens many times since the PC system was updated from openSUSE 11.3 to 11.4 one month ago.
It's really random and I don't know when it will happen next time. But when it happens then I have no choice but to restart computer again. I notice that every time when PC freezes, the Xorg occupies 100% cpu resource and as long as keeping this status. Even when the PC dose not freeze, I feel the mouse point does not moves so smoothly. It could stop for a very very short time in its moving. I did not find this moving problem when I was using openSUSE 11.3. I guess it may caused by the video card driver which may not installed appropriately on my openSUSE 11.4.
Using "lspci |grep VGA" I get the following video card information:
01:00.0 VGA compatible controller: nVidia Corporation GT218 [GeForce 210] (rev a2)

Since the update to 11.3 i'm getting kernel panics randomly. Because the X server freezes and I can only force an "unexpected reboot", there is not much information I have. I installed kdump and activated it with the Yast module. I'm collecting dump files, now. But I'm not sure what to do with does files.

I just upgraded my system from oS 11.2 to oS 11.3 on Thursday. I've chosen the network-CD and booted from an USB-pen-drive, as my netbook doesn't have a CD-drive.I new experience that my computer freezes obviously randomly. It's not just a programme crashing, but the whole computer just halts. Nothings working anymore - mouse is not moving, keyboard doesn't respond, I can't even switch to another tty.I tried to remember what I was doing right before the crashes. Once I used the new netbook-desktop of KDE and had typed for an application in that "cool" new desktop. The desktop wend "blank" (the application folders disappeared and I was waiting till the results were shown) and then the computer froze. Just right now I used Okular, selected some text and opened the context-menu when the computer died, the other time I closed the Yakuake with F12 and the computer didn't respond just right before the window was minimized at the top and last but not least I had that "Expose"-like window arrangement opened and clicked at the black background when everything hang up.
What could be the reason for it? oS 11.2 worked perfectly - I hadn't had any crash during 5 months of intense use. I suspected the new graphics driver, but I can't find any reported bug about the Intel 945 GMA* or anything about the new KDE 4.4.4 on atom processors.

Since I started to use Suse 11.3, I've been having problems with my sound card. It starts normally and I can use it without further problems, until it randomly stops working. I don't know what causes it to stop working, it just does. Then, if I go to YaST>Hardware>Sound (it shows I have a 82801G (ICH7 Family) High Definition Audio Controller), press edit then reset, it works again!
I've been doing this for like 4 months, but I'm growing tired of doing it and not being able to just sit back and enjoy music on the amarok. I don't know what should I report, so that's why I only say the sound card identification.

I have openSUSE 11.2 with default GNOME desktop and i'm facing issues with keyboard layouts, which are changing randomly. Problem is that i have GNOME in Slovak language and therefore has openSUSE set durring installation my keyboard layout to 'Slovak' but i always change it to 'Slovak QWERTY' which suits me better.
Problem is that randomly system adds back to my layouts which are 'Slovak QWERTY' and 'USA' also original 'Slovak' layout which was previously removed.
I must always manually remove this third layout and it's very frustrating. Many times on fresh system boot it's anyway back and so on and on... Where may lie the problem? Why is GNOME not respecting my settings? In Ubuntu i never have these basic issues. Are there on system boot some specific SUSE triggers which are overwriting my configuration?
