Ubuntu Installation :: 11.04 PXE Shuts Down Ethernet On Hotplug
May 1, 2010
Trying to install Natty 11.04 via PXE. The ethernet is a Realtek RTL8168d/8111d gigabit. It DHCPs and configures just fine. Then it downloads what it needs for partitioning and does that. After partitioning, it runs net/hw-detect.hotplug which discovers the interface as new, then strips it of any configuration so it can not proceed further. Is there any way to disable this secondary hotplug detection of the ethernet interface?

I've only recently switched to Ubuntu and overall I'm loving it. When i first installed it shut down perfectly from the GUI. After updating from the Update Manager, I've had problems. Now it shuts down but my PC doesn't power down.
I can manually make it shut and power down from the terminal with the command:
sudo shutdown -h -P now
or:
sudo poweroff
The fact that it works from the Terminal but not from the GUI suggests there might be a coding problem with the GUI but discovering and fixing that is way beyond my capabilties.

About two months ago my Ubuntu desktop computer (running Ubuntu 10.04) started giving me trouble. The monitor would occasionally shut off after booting up and logging in and using it for a few minutes. Then this started happening every single time I booted up the machine, making it effectively useless. I decided to try a fresh install of Ubuntu 10.10, and, luckily for whatever reason I was able to get the monitor to *not* shut off long enough to get this new installation to actually install. But now, after installing 10.10 the computer is doing the same thing, shutting the monitor off after boot up and/or login. Sometimes I can get to the login screen, sometimes I can even actually log in, but even after I log in, the monitor shuts off after a few minutes. I can access the BIOS just fine, of course, and I can get to the GRUB menu just fine by pressing ESC on boot up, but I cannot even get the root access on recovery mode to work for more than a few seconds before the monitor just shuts off - usually it shuts off right before I can even arrow down to select root access from the menu when I boot to recovery mode. In terms of hardware, I tried installing a new power supply, but that hasn't worked.
I also tried changing the GRUB command for the boot, where you go to the GRUB editor and add nomodeset, i915.modeset=1, i915.modeset=0 or xforcevesa after splash quiet, but that also doesn't work. The video/graphics card is just the built-in Intel video (PCI-E or something like that, part of the motherboard basically). It's an MSI motherbaord from a couple of years ago, American Megatrends, but the BIOS appears up-to-date. Anyway, I've tried everything and I am just about to give up. Ubuntu had been working fine for me for a couple of years on this machine, with no hardware changes, right up until that first week of November, 2010. Could there have been some automatic software update that ruined my machine? The OS is Ubuntu 10.10, and the Linux kernel is 2.6.35-22-generic. Also, if it matters, this same machine has had that hda-spurious response warning thing that appears on boot sometimes because of the Intel built-in audio configuration. That's been happening since a few versions of Ubuntu ago, so I don't know if it is related.

I have a NVIDIA Geforce 6150 LE video card and it is on the motherboard. I vaguely remember something on some site about nvidia cards, but can't remember what. It gets to the part where it says something like "Boot Ubuntu from the CD." I hit enter and it shuts my monitor off.

The machine I'm running is a Sony Vaio VPCCW290X notebookIntel Core i5 processorNvidia GeForce 310M video cardI am planning on making Debian my main OS but I am experimenting with installing it on a usb drive first. I am new to linux so this has been a learning experience so far. I finally got the grub installed correctly for the external hard drive to boot up into Debian. I installed the minimal network install so I should just be going to a console prompt. After booting it it goes for a short time and then the screen shuts off, not just black. I tried ctrl-alt-f1/f2 which didn't do anything. I am able to reboot by ctrl-alt-del though. If I try to boot into the second option it goes further before shutting off. Using a live cd it does the same thing unless I choose the fail-safe option. When I choose that it boots up correctly. If I hook up an external monitor it will switch over to it when the screen shuts off, so I know it's not the video card

I have downloaded the latest version of Debian for PPC to run on my iMac G3 600MHz 1GB ram. The problem is, is when it is partitioning the HD the computer just shuts down and restarts from the beginning. I don't understand this. I chose it to erase and use the entire disk. The HD is 80GB. I really want to install this OS!

I'm running Linux 2.6.35.4 on a Kontron COMExpress board. The device has 2 battery slots so that a user can hot swap batteries while the device is running.The problem I'm having is that battery information is never updated in /sys unless I read /proc/acpi/BAT[12]/state.When booting the device, the battery state is correctly detected by the kernel but after that it seems like nothing happens.
My current solution is to poke at /proc from time to time, it works but I'm forced to compile my kernel with CONFIG_ACPI_PROCFS_POWER which is marked as deprecated..

Current stable Debian runs on both machines. I connect a digital camera to the USB on the server ("a") and the camera's filesystem is mounted automatically.I want that same filesystem to be made available to the other machine ("b") through nfs.What should be in fstab for that filesystem, or is something else needed in the configuration for "b" in order to access the filesystem which is physically on "a"?

Hotplug of USB not working after yum update.Fedora 11, with KDE4.3.4-1 Kernel 2.6.30.10-105.fc11.i686.PAE.This problem occurred after I ran "yum update" on 28th December 2009, which updated the kernel to the current above version, from 2.6.30.9-96.c11.i686. PAE.Prior to this update, when a USB device(either a scanner, printer, pendrive or camera) was plugged in (hotplug) the device was detected and could be used by the appropriate application. The camera and pendrives were reported by the KDE Device Notifier.
I can mount the pendrive and camera manually, but I cannot use the scanner or printer applications as the devices are not seen.Interestingly if the printer and scanner devices are plugged in/switched on at boot time,they are seen and are usable, eg the Scanner-Tool sees the scanners and the printers print.Logging in as root, exhibits the same symptoms.This feature has occurred on two machines, both after running yum update.Please what has broken with this yum update.How can I overcome this "feature".

The following config works and creates a good VM in Xen:
Code:
# Kernel Setup
kernel = "/boot/vmlinuz-2.6.18.8-xenU"
# Memory
memory = "256"
# Disk
disk = [
"file:/opt/xen/domains/110/sda1.img,sda1,w",
"file:/opt/xen/domains/110/swap.img,sda2,w"
]
# container name
name = "110"
hostname = "boo"
# Networking
vif = ["type=ieomu, bridge=xenbr0"]
# VNC
vnc = 1
#vfb = [ 'type=vnc,vncdisplay=2,vnclisten=0.0.0.0,vncpasswd=110' ]
# Behavior Settings
root = "/dev/sda1"
extra = "fastboot"
But when I uncomment the VFB line, I get the following error after it hangs for at least 30 seconds:
Code:
[root@customer 110]# xm create boo.cfg
Using config file "./boo.cfg".
Error: Device 0 (vkbd) could not be connected. Hotplug scripts not working.
Part two of this question:
Sometimes it actually works, and a port is opened. When this happens, nmap shows the VNC ports open and I can connect via the VNC client, but it just hangs at "Connection established." and no VNC display shows up. I've tried multiple VNC clients (TightVNC, TightVNC Java Console, RealVNC), but they all fail to connect. Does VNC through Xen require X to be started in order to function? I was under the impression that it would show the console screen.

I was just wondering if there's any point having both auto and allow-hotplug against the same interface in network/interfaces as allow-hotplug seems to bring an interface up at boot on its own.

My Ubuntu laptop gets docked into a few different locations per day with different hardware and use cases. I'd like to automate the preference settings for each of these locations:
Work computer, dual head 1280x1024
External USB audio and bluetooth audio
Home computer, dual head 1280x1024, 1080p
External USB audio
Basically, when I dock the box in either (1) or (2), I want to automagically get the right xrandr settings for the different screen geometries and the right audio routing.
What scripts, etc. are responsible for the inscrutable default behavior?
Are there packages for customizing this?
If I wanted to roll my own, what is the right library to use to catch the hotplug events?

I'm having trouble getting a PCIe device to show up in lspci using pcie hotplug.
After booting the system I load the pciehp module, I then plug-in my PCIe card. After that I do an lspci, but I don't see my PCIe card. When I cold boot with the PCIe card installed the system sees it fine, i.e. it show up in lspci.
Does anyone know of an easy way to figure out if my hardware even supports pcie hotplug?
When I load the hotplug module I just do a modprobe pciehp. Is this all I need to do prior to plugging-in my pcie card?
I will try running pciehp with debugging turn on to see if that gives me any additional info.

I am running Fedora 12 on a T400 Thinkpad. When connector my external monitor prior to powering on the computer or if I restart it, I get a lot of resolution choices from xrandr. See below.
Code:
$ xrandr
Screen 0: minimum 320 x 200, current 1440 x 900, maximum 8192 x 8192
LVDS1 connected 1440x900+0+0 (normal left inverted right x axis y axis) 303mm x 190mm
1440x900 60.0*+ 50.0
1024x768 60.0
[Code].....
Is there some daemon I need to restart to detect the monitor resolutions correctly, or is there a module I can reload?
There seem to several variables to reproducing the behavior. If I restart without the laptop without the monitor plugged in, log in, and then, plug the monitor in with the monitor powered on prior to plugging, all resolutions are detected properly. However, if I plug the monitor in with it powered off, then power it on, I only get the few options shown in above. Once I get the reduced number of options, it seems to stay that way till I restart regardless of how I unplug the monitor.
I have found a work-around by just forcing the modes with xrandr --newmode and xrandr --addmode, but I would much rather have the modes autodetected.

I have a new 64 bit workstation (Dell Vostro i7) which I usually keep running for extended periods (read; days and weeks). I have realized that the system completely ignores when I insert a USB stick (LaCie 8Gb USB Key). By ignore, I mean it doesn't get mounted, and /media/ is empty. Interesting enough if I go into YAST and probe for Hardware Information, I find my USB stick there under the USB section. There is no specific entry for the key in /etc/fstab by the way, as far as I know I don't need to specify how a USB stick should be mounted. Auto-mount, when it actually works, is perfectly fine.

OpenSuSE 11.3/KDE4 32-bit
Kernel 2.6.34.7-0.7-desktop
It's been a while but I just hit a brick wall. Well, this has been building for a week or so, I can't figure out what's causing it. I thought there was a sudden conflich with the bluetooth dongle, since that one piece of hardware is not listed right from boot (sometimes has a dmesg error related to loading the module), but I find now this is not the case. Today I ran the full update to the current kernel hoping to fix the problem, but to no avail (caused some interesting issued with the video (intel 945) which I ironed out). Symptom: With the exception of the bluetooth, all devices hooked up to the USB ports at boot are recognized and usable. No device that I plug in after booting is recognized, period. lsusb output does not change. Plugging in a USB flash drive produces no output for dmesg.

I am basically wanting to use my Ubuntu 10.10 computer as a router. Note: Before you say just get a router please note that I am poor/cheap. I have two ethernet connections and one wireless connection on my netbook. I want to share the internet connection that is going into one of the ethernet cards through the other ethernet card and the wireless card.
DSL-->1sr Eth --> 2nd Eth (currently works)
DSL-->1sr Eth --> Wireless Card (Adhoc) <--(connects with limited connectivity AKA no internet)
The 2nd Ethernet card already has working internet, but when I connect to the Wireless card (through an Adhoc network), it cannot get an IP (I believe).

I've installed VMware server 2.x on my windows XP SP2 and installed Ubuntu 9.10 on the VMWare. I have noticed several times that the ubuntu machines shuts it down (not sure the time pattern but it could be that it shuts down after a certain minutes idle). As a result of that, I always have to restart it.
I checked the event log viewer, it looks like there's always a segfault just before it shuts down. I've pasted the last few lines of event log below.

After so recent updates, I find the network connections has changed.
I see now that it connects to the network (dsl) by default. I unchecked the box 'connect automatically', yet it still is connected by the time the monitor turns on when awakened from sleep or hibernation.
How can I get the auto network connection turned off without physically pulling the plug?

Ubtuntu 10.04. I'm simply trying to run through this fix [URL]. But I'm not getting very far. Where do I unpack the files to? And once I've edited the wl_linux.c file, how do I compile it? I'm new to Ubuntu and I've been at this for days now, here's my previous issue before I ended up with this one [URL]. I thought Linux based software was supposed to be reasonably trouble free? I've been trying to get my laptop up and running for close to a week now, I had less trouble with Windows!

I've been using Ubuntu on my desktop for a while and it worked like a charm. Three months ago, I decided to put a new cpu fan because the old one was gathering dust and I wanted to have lower cpu temps. I decided to buy an Scythe Kabuto, nd installed it with no problems. Windows XP works perfect, but the problems come when I try to start Ubuntu, both from a Live CD or from the HD. Ubuntu starts normally, but in a short period of time (2~15 minutes) the PC randomly shuts down. I've seen some errors when I restart and try to start Ubuntu again mentioning high CPU tempetatures. The fact is that the CPU temperature never reaches more than 65, so my guess is that there is some problems with the ACPI and temp reading.

Ubuntu shuts itself down and displays message that it is running low on graphics, giving me options to run in low graphics mode or to troubleshoot. I have been given the following advice but have no idea what to do:
You are using the open driver i915 as you are using an intel based video
chip.
Sounds like you need an xorg.conf file to define the display a little better as udev is not detecting. Here is a sample file you can start with: (Refers to a URL that led me to this forum)
You can ignore any sections and entrys regarding keyboards as udev is
pretty awesome at picking those up

I'm trying to install a second NIC on a computer running 10.10 x64 server edition, but am having a bit of trouble and hoping someone can help. I got a used gigabit PCIe ethernet adapter and hooked it up, but it didn't display when I ran ifconfig, so I assumed that it was broken. However, when I plugged in a known working 10/100 adapter from another machine it also wasn't configured.
I then did a bit of investigating and found that both cards ARE detected, but are unable to work for an unknown reason. Here's the output of "sudo lspci | grep -r Ethernet"

If I then unplug the ethernet from the switch and then replug it in, eth0 will get a steady connection, at which point I have to run the following command to get everything working.
Code:
sudo dhclient eth0
After running the command I have no issues with the ethernet connection.
