Ubuntu :: NetworkManager.state Changes Not Saving On Reboot
Mar 12, 2011
This is my last attempt at solving this issue before I have to return to windows as I need to contact family via web. I am unable to connect to the wireless network at home since upgrading to Ubuntu 10 desktop. It worked fine on v9. I reinstalled a full U 10 version but same issue. I am trying to enable wireless in the file mentioned as this seems to solve most posters issues but for some reason when I reboot it loses the update. I've tired logged in as su and sudo i but no joy.
I've always used the network init service to manage my network interfaces on headless servers and used NetworkManager on desktop installs. Lately it seems that NetworkManger is becoming more and more integrated into network management even on servers. I have a RHEL6 server in my lab that runs NM without any Gnome components installed and I've noticed in Fedora NM becoming more tightly coupled with the system-config-network related services.
I'm asking because this is a "highly connected" server, with two redundant NICs on each of two different networks with a bond interface associating each pair for redundancy. Every time the server reboots it fails to configure its default route correctly. I know how to configure the network using the standard /etc/sysconfig/network and ifcfg-* scripts. Is NM fully integrated with these configuration files?
I have been running Xubuntu Lucid for a couple of days and so far the only problem I have been having is with hibernation. When I hibernate, it saves the state, shuts off the computer, but then the computer starts again.
I have looked around a bit in the hibernation scripts (/etc/acpi/hibernate.sh) and changed some of the pm configuration files (added "HIBERNATE_MODE = shutdown" to the end of /etc/pm/config.d/00sleep_module) to no avail.
My computer is an IBM ThinkCentre. I am not exactly sure on the specific model, but I believe it is m51.
EDIT: If it makes any difference, this was an Ubuntu install that I changed to a Xubuntu install by doing "apt-get remove liborbit2" (I found this instruction on a website) and then "apt-get install xubuntu-desktop".
After updating from 11.3 to 11.4 the networkmanager stopped working for me. When I hover over the KDE NetworkManager icon it says Error: Invalid state. If I click it, it says Network Management disabled and checkboxes (Enable networking and enable wireless - both checked). I already tried removing /var/lib/NetworkManager/NetworkManager.state and restarting the network management (/etc/init.d/network restart). Also reinstalling the NetworkManager package.
I've got my ATI driver installed, now I am trying to configure it. I have a laptop plugged into a docking station with an external monitor. I would like to use the external monitor only
I run the admin ATI Catalyst control center (amdcccle) configuration GUI, set up my settings, just as stated above (i.e. laptop monitor off, external LCD on). Works great! Then I reboot... and I have to configure it all over again
Initially, Debian detected my M-Audio soundcard right off, and things were going great, until I tried to get a Logitech webcam working. Got video going, but no audio, so I installed cheese, alsa-base and alsa-utils, and played around with settings according to copious forum threads dedicated to the problem of Linux and webcams, all to no avail. Then I had NO SOUND, until I did a alsa-conf, which detected and (re)set my M-Audio card, until reboot, then again, NO SOUND. Settings were not saving through reboot.
So I purge removed alsa-base and alsa-utils, hoping that things would magically revert to pre-webcam experiment. Still no sound. I have given up on the webcam idea; I'll use my XP Pro laptop for that. But I need sound on this Linux box. Oh and when I'm playing ....., etc. the soundcard itself is making chatter noises to the beat of the music. This soundcard was working perfectly before I started the webcam debacle, so it's not a hardware issue.
Having openSUSE 11.2, Firefox (latest release) is having some issues when comes to "saving image as", it fails to offer "saving window"? Konqueror works normal, what could be the problem with Firefox?
I am using sda1 as /, which is a bootable drive. I do not know if my problem is that I did not create a /boot drive. After removing the iso dvd, I tried to reboot and I get this back: -bash: /sbin/reboot: input/output error Then it returns me to the terminal prompt.
My laptop keeps saying Checking battery state is that something to worry about? The laptop goes has a black screen on it saying Checking battery state then says ok.
I dual boot both Windows and Linux and I often put my computer to "sleep" at night so it's easy to wake up the next morning. In Windows I just need to press a few keys and my computer comes to life, in Linux this doesn't happen and I have to actually go for the power button. (This wouldn't be so bad if the computer wasn't in a hard to reach place in a cupboard) At the moment I have a USB hub which my keyboard and mouse plug into, but for the sake of testing I plugged a second USB keyboard directly into the machine itself, again neither wake it. Doing a bit of research I have discovered that the wakeup devices are stored in /proc/acpi/wakeup The contents of the file by "cat" are as follows:
Code:
monotoko@KatieIV:~$ cat /proc/acpi/wakeup DeviceS-state Status Sysfs node PCE2 S4*disabled pci:0000:00:02.0
[code]...
At this point I have reached a dead end, how do I tell the acpi wakeup to accept input from USB keyboard as a kickstart?
My experience with external monitors in Linux is harrying at best. It's getting better, but it still ain't perfect. My current experience (I have an nVidia card, with nVidia drivers, on a Vostro laptop):
Turn on computer (booting Karmic). Connect external monitor Click on System->Preferences->Display Redirect to nVidia's tool Perform at least 8 more clicks to enable secondary monitor. Realize resolution isn't optimal and set it with another few clicks. Click Apply Accept changes Quit, then really quit, the app.
I always have to set the resolution, it doesn't detect it automatically. The main screen is *always* on the external monitor no matter my settings. I'm screwed if I unplug the monitor but forget to go through steps 1-8, this time disabling the external monitor. I have to replug it in, then turn it off, then I can unplug it. If I unplug the external monitor and plug in another one (going through steps 1-8 twice more) with different resolution capabilities (e.g. a projector), the settings get all messed up again.
Why can't adding an external monitor be automatic? It nearly is on OS X for instance. I plug it in, and it automatically detects the monitor and makes it a secondary monitor, or mirrors them, or turns it on and turns off the laptop screen. All the while being consistent about it. When I unplug the monitor, it knows instantly that I've done that, and reconfigures the laptop screen once again.
I imagine the answer is because no one has stepped up to do it yet, or it's in progress. So my question: what *is* the state of external monitor codes in Linux, and are there any plans to implement them in Lucid? Further, what would be a project, with *user friendly* context, to which I could tune in?
Or, am I not aware of the "right way" to do it?
I define user friendly as roughly the level of kernelnewbies.org . That is, kn.org is my gauge of what I can understand.
I would like to save the state of my windows. I use many of them at once for programming. With the hibernation mode, I can do that, it work. I want to know how can I do that if I completely shutdonw the computer.
I have two computer systems at home (a laptop and a pc), one with ubuntu 9.10 and the other being windows 7. Since i recently discovered how awesome counter-strike:source runs on the latest edition of Wine, I no longer need Windows 7 on my system.
The question is, I have partitioned my laptop at least 5 times the last 6 months, and I want to find out if my hard drive could cope with repartitioning once more. Could you guys please give me the name of a tool for Windows to check the state of my hard drive?
My brother gave me a copy of Ubuntu 10, since my upgrade from 7.04 to 7.10 screwed up. Installed it easy. But strange problems occur. After a few minutes of starting the system, it enters a command prompt, regarding "Checking batter state" yet my computer runs on an adapter, no battery exists (except the built-in one on the motherboard), and I have to restart my computer.
I recently had a problem in Ubuntu 11.04. I had just installed GNOME 3, however, I didn't really like it as much so I decided to go back using GNOME 2,but then a whole bunch of things happened. I tried re-installing GNOME 2,but then I lost the Ubuntu enviorment and stuck only with GNOME and now I'm only left with a terminal whenever I log in. how to restore Ubuntu 11.04 back to its original state, like as if it had a fresh installation?
I have either ubuntu 9.x or 10.z.When the upper panel displayed double graphic postings of the icons (such as clock : clock ), I right clicked and selected remove. I was expecting one of the icons to be removed. Instead, the whole upper panel disappeared. Now I only have a GoogleEarth icon on my desktop main field. On the bottom panel, there are only two null desktop icons and one trash folder icon.How do I bring up a terminal window from this state?
i am currently trying to do software raid 1 on a running ubuntu 9.10 system with mdadm. I might have done something wrong and im trying to go back from the beginning. Does anyone know how to remove all the raid info from a harddisk and get it back to its original state.
Had a laptop with a Hardy install - my two year old knocked it on the floor and after that it no longer recognized the drive, and I could hear the hard drive read head hit the platter when it tried to read it.
I bought a new Kingston 128GB solid state drive to replace my old 40GB drive - figure it will be more robust.
I tried installing Lucid, and it stopped after partitioning the drive and was unable to format it. I attempted to use my old Hardy install disks, and had the same issue. I spent time with Kingston tech support, they had me try a few things, then RMA'd me a new drive. New drive still had the same error.
I figured something else must've broke and let it be for a while. Today, just for the heck of it, I attempted to install XP on it. Flawless. So, it's not a hardware issue.
Any known issues with the Ubuntu installer and Laptop SATA-2 Solid State Drives? (I'll put more details in a later post if needed, don't have them at this very moment)
Updated from 10.04 to 10.10 about 2 weeks ago and it worked just fine until today. After rebooting, it's stuck at "* Checking battery state" and nothing happens. I've tried with power cord inserted/out and without battery but with no success.
What I did before rebooting was that I tried to fix my iphone tethering problems with the following commands:
And also a system update. And here I am. Anyone knows what could have happened? I'm on a Acer Travelmate 8371.
I've recently upgraded to 10.10 and am having the same problems as with all the previous versions. I have no eth0 connection at this moment, only lo. I have an Hp pavilion about three years old with a onboard ethernet, connected to router and wired broadband. The thing is, when I am in Windows, the internet will also drop, going into "local only." I can always get that back though by running the network diagnose. Another thing. How to I get into the network.state file to make changes?
Every time I try to boot into Ubuntu, it never goes any further than Checking battery state. Once it gets there it pauses for about 2 minutes then goes to and doesn't go any further. I can still press CTRL+ALT+F(1-6) to get to a command line, but I'm kinda n00bish when it comes to the command line.
Is there a command I can implement into a script that I am working on to change the maximization state of a window (maximize/restore)? I know there is a keyboard shortcut (Alt + F10), and I'm not interested in doing that.
Today when I went to boot up my computer, it hung at "Checking battery state...". I have never had any problems before this, and have been using 10.10 for several months. The only change I made that I can think of was installing the Wacom Control Panel. I have no idea what to do, and really, really don't want to reinstall Ubuntu unless there's no other option.
