Ubuntu :: USB Not Detected & Shutdown Not Working
Oct 4, 2010
I am listing both problems on one post because what I have read, they may be related. I am working on a Compaq Presario SR1603WM. I have installed 10.04 three times thinking I may have gotten a poor install. The computer has two issues and everything else appears to be working properly. The main problem is that the USB's aren't detected. There are 4 on the back and three on the front. They have power, but the computer doesn't detect when a drive is inserted. The card reader does not work either. The second problem is that when you shutdown the computer, it hangs on the "purple Ubuntu" screen until you press and hold the power button. Restart works just fine.

I run ubuntu 9.10. I recently convinced my wife to give it a shot. The problem is, the bluetooth dongle is detected and the icon appears when its plugged in, the mouse is found and says it is pointing in bluetooth manager but it does not move the cursor on the screen. I have tried 2 different dongles and both work correctly and control the mouse on my asus laptop. She is using a toshiba satelite. Both dongles show up in lsusb as hci0. I've tried everything on the forums and everything I could think of but no go. If she doesn't have use of the mouse for farmville I will be in trouble.

I am running Karmic on a Compaq Presario V3000 and this morning my wireless card is not being detected by Ubuntu's NetworkManager. I have no idea what caused this... literally, it was working when I shutdown my laptop last night. When I right-click the NetworkManager icon in the panel it does not show "Enable Wireless" (only "Enable Networking"). When I run ifconfig in terminal it shows my wireless card as being there (UP Broadcast Multicast). One weird thing - on the front of the laptop there is an LED which lights up blue when the card is working (ie normally), but right now it is orange (ie, if you flick the switch on the front of the laptop to toggle the wifi on or off... I have toggled it back and forth but nothing changes!)

I am using Ktorrent 3.3.4 (compiled - using KDE 4.3.2) on Ubuntu version 9.10 (Ubuntu 2.6.31-19-generic)
I have tested the shutdown plugin to shutdown when all torrents stop downloading and also tested by selecting when events below happen and manually selecting the torrents.
I have the shutdown button selected.
However on both occasions my PC does not shutdown after the downloads have completed.
What am I doing wrong? Or is it because I am on Ubuntu and using the Gnome desktop and this only works for KDE?

Recently xsane has stopped detecting my MFP (HP Deskjet F2280). My setup has not had any hardware changes and the only software changes in that time have been the periodic Synaptic updates. Before this hiccup all had been well for over a year. If I run xsane it thinks a while (10 sec?) and tells me in a little panel no devices were detected. If I run lsusb, it finds the device, but after all it is a printer/scanner and the printing function continues to be OK so this is not a surprise.
I do not know enough to understand all the lsusb output to know if anything is amiss in the detail. What is it that xsane needs so that it detects the device as a scanner? Is there a file or specific stuff in a file which I could get from an old backup or edit (carefully!) by hand? I don't need the scanning function often enough to pin down what might have done the mischief.

I started on ubuntu 8.10 and my wireless card has always worked,Since i did a fresh install of ubuntu 10.04 it still seems to work to a point.I can see networks, click them and use a password to connect but it never seems to carry on, I typed the password correctly and after a minute it asks for it again.I have read a post about problems other people are having and that i need to install a different program.But i cant install another program if there is no wireless as apt-get doesn't work without internet connection.So... I need to download something that will fix it (possible update if one has been released) to xp (partition) then access xp partition from ubuntu and install it.

i installed a linux flavor (Ubuntu 10.04 LTS, Ubuntu 11.04, and then Linux Mint).. They all gave this same problem about the wired network (see the picture). The connection seems to be fine but i can't connect to internet or even to my router. Which is weird since it knows my router IP 192.168.1.79. Wasted the whole night trying to figure it out but i just can't understand why. I have a separate partition on this computer to run Win7 also and confirmed that the network connection is working.

I'm running Ubuntu server 8.04.3 with eBox on a Dell GX280. I want to power off my box automatically every night, so as root I added a crontab entry "05 1 * * * /sbin/shutdown -P now". The command runs on schedule but most days the PC goes into a coma instead of powering off. It doesn't respond to key presses or mouse movement or Ctrl-Alt-Delete, I have to push its power button to complete the shutdown. I have tried a variety of alternatives such as "/sbin/shutdown -h" and "runlevel 0", they all behave the same way

i'm using Ubuntu in my office. I have to report two issues with network connectivity.1. Wireless doesn't work if come back after suspend/hibernate the computer. The work around I follow is,a. Turnoff the wifi and restart the computer. (It won't shutdown. have to do force using the power button)b. Reinstall the network-manager_0.8-0ubuntu3_amd64.deb and network-manager-gnome_0.8-0ubuntu3_amd64.debc. Restart the computer (Again it won't shutdown. Need force.)d. Now wifi will detect the networks and shutdown works fine hereafter.2. Sometimes the wired gets disconnect frequently (thrice in 2minutes). Physical connectivity is good and working well in Windows.

I am new to Linux and after a lot of research I settled on CentOS to be my OS for Linux. But I am having trouble with sound right now as I can not play audio. The command system-config-soundcard opened a gui for audio configuration saying following device is detected - Intel Corp. 82801(ICH9 Family) HD Audio Controller.
Ouput for some commands are given below::
[root@localhost ~]# lspci
00:00.0 Host bridge: Intel Corporation Mobile 4 Series Chipset Memory Controller Hub (rev 07)
00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07) .....
[root@localhost ~]# uname -r
2.6.18-164.el5
[root@localhost ~]# cat /etc/redhat-release
CentOS release 5.4 (Final)
Clicking on the volume icon gives me message that either Gstreamer plugins are not installed or sound card is not configured.
While Trying to install gstreamer using YUM, I got following message:
[root@localhost ~]# yum install gstreamer
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile .....
Setting up Install Process
Package gstreamer-0.10.20-3.el5.x86_64 already installed and latest version
Package gstreamer-0.10.20-3.el5.i386 already installed and latest version
Nothing to do
[root@localhost ~]#
So I guess gstreamer are installed but how to configure the sound card or is there any other problem.

After NFS mounting some system folders (i.e. lib, usr) of a slave cluster node to /lib & /usr located on the master cluster server I got into some problems: I forgot Ubuntu 10.04 was installed on this particular slave node, while the master node runs 9.10. Now, I am not able to unmount these folders using umount, or restart the system using shutdown, I get some error: " /lib/libblkid.so.1: version `BLKID_2.17' not found". Is there an alternative way to unmount these NFS shares, or to restart the system to undo the mounts? The systems are located elsewhere, so just physically restarting the system would not be the preferred option.

I'm trying to make my system automatically shutdown once the battery level is low, but still without success. I've tried kpowersave, gnome-power-manager, kpower, klaptop but none of these worked for me. Well, I can't imagine I would be that stupid, but simply it doesn't work. In all cases mentioned above (kpower, klaptop, gnome-power-manager) I've tried to setup the laptop to shutdown once the defined level is reached, but the laptop never actually switched off unless all the battery was drained.
Btw. I think all the above mentioned apps only work once the user is logged in. But I'd like the solution to work also when the PC is on without anyone logged in. I thought I could write a bash script based on parsing of acpitools output and define it as a service, which would monitor the battery level, but I simply don't believe there isn't any functional solution to this.

I have installed a cluster computer with 10 nodes . The manufacturer is HP . All nodes and the master node have redhat enterprise linux installed in them . When I shutdown the nodes from the master terminal using "shutdown -h now" they get shutdown . But they dont get completely turned off . This issue bothers me when the power supply is given , all nodes boot up simultaneously generating a huge heat .
Thing to note : When we shutdown our PC they get completely turned off . When the power supply is given , a press on the Power On button is required to boot the system. But , why does it not happpen in the case of cluster? Is there any other way of completely turning off the nodes from the master terminal ?

I installed Mythbuntu 9.04 about 9 months to a year ago and (for the most part) I haven't had any problems with mythwelcome, automatic shutdown or the system clock. The "for the most part" relates to the fact that the clock on mythbuntu has always been 4 minutes fast. Then, just last week, the system started acting up - for some reason the system clock changed to 8-10 minutes fast (6 minutes faster than it was previously). To fix this problem, I have tried manually setting the "time and date" setting, and I have also tried setting the "time and date" setting to sync with an internet server. Lastly, I tried changing the system time through the motherboard bios. In each situation, mythwelcome would initially start up with the correct time. Then, several seconds later, the time shown in mythwelcome would change to being 4 minutes fast (as I described above). The time would also be 4 minutes fast when I enter the frontend.
I was willing to live with this, but the weird part is that when I start the system now (assuming I don't have any programs scheduled to record), mythwelcome boots up fine and I see the indication that "MythTV is idel and will shutdown in XXX seconds". Then, it flashes to "MythTV is idle" - like it used to; except now, it doesn't flash back to the countdown for shutting down mythtv. One time when I started the system when I was adjusting the time as mentioned above, I noticed that mythwelcome went to the "MythTV is idle" around the same time it changed the clock to 4 minutes fast - I think there is definitely a correlation here.
I checked out all the settings and nothing else has been changed that would otherwise affect MythTV from shutting itself down. The other interesting part is that I can get the shutdown countdown back if I go to "Utilities / Setup", "Setup", and "Mythbuntu". In the popup screen I choose "MythTV Configuration" and select "Launch MythTV Setup". I get a popup box that says that the mythbackend must be closed (as expected). Then I immediately exit mythtv-setup and the system runs "mythfilldatabase". I exit the Mythbuntu Control Centre and exit the frontend. When I get back to mythwelcome, the shutdown countdown comes back.

Recently I installed vncserver (tigervnc) on my desktop. Ever since my computer refuses to shutdown normally. At shutdown the following message pops up: Quote: System policy prevents stopping the system when other users are logged in Then I have to enter the root password to shutdown. If I stop vncserver before, the computer shuts down normally.

Hi everyone,
Encountering several problems with ubuntu. I have managed to burn iso to cd - I decided to bot ubuntu off the cd, I have been struggling with a couple of problems all to no avail. I have heard ubuntu is pretty damn good, and I was quite enthusiastic about it. But if I can't get this sorted...
Oh I should also say I have never used a command line and I have not a clue about xorg or whatever you call it.
anyway my first problem is Display settings. I can go to System > Preferences > Display, and the largest I can set my resolution to is 800*640 and the monitor is unknown...?
Problem number 2 - the ubuntu software centre is not working... Applications > USC > Could not launch Ubuntu Software Centre..
Problem 3 - In the bar at the top of the screen beside time and date etc, "Crash report detected" keeps popping up?
Problem 4 my @ and " keys have swapped places??? also my Pounds sign (I live in UK) has been replaced with # while # has been replaced with
I have been working for a couple of hours on it but nothing makes the slightest bit of difference. I will probably have some more problems soon to be honest - but your help with the above problems would be honestly fantastic.
edit: Yea I cant install flash player to watch videos on .....?
Applications > Acessories > Terminal will not bring anything up anyway!
Open office does not work

I cannot locate shutdown log for Linux shutdown to check various activities carried out during shutdown. I can view Startup Log which is availble on console>Applications>System Tools>System Logs.
I have included Shutdown/Startup in dbora, so that Oracle 10gR2 Shutdown/Startup will be automated during OS Shutdown/Startup.
I want to check Shutdown log because Oracle Shutdown was not running, as from $ORACLE_HOME/shutdown.log contains no entries, where as startup log contains latest startup details.
That means here 2 issues are there. One, I want to locate OS Shutdown Log and the other being Why Oracle Shutdown not getting executed.

I did a live upgrade from 11.3 KDE and observe a following issue.When I press the shutdown button on the laptop it initiates the shutdown and shuts down fine but after a significant delay of time (something like 30 seconds). When I click the shutdown button in KDE it initiates the shutdown instantly. This was not the case in 11.3 where the shutdown worked the same regardless of the method that triggered it

Further to this LQ thread which Tinkster solved by suggesting the last command (thanks Tinkster) I have been exploring last -x reboot and have found that the reported duration is incorrect for the last reboot and shutdown when a old wtmp file is used. Not having a record for the following shutdown, last assumes that the system has been up until the current time and similarly for the shutdown.
The output comes in time order, latest first, each line showing the time of the reboot and the uptime from then to shutdown. Using last -x reboot shutdown to show the shutdown time, here's an illustration
Code:
shutdown system down 2.6.29.6-smp Sun Mar 7 15:35 - 03:02 (11:27)
reboot system boot 2.6.29.6-smp Sun Mar 7 09:35 (05:59)
09:35 until 15:35 is 05:59.
When the uptime exceeds 24 hours it is shown as (<days>+<hours:minutes) like this
Code:
shutdown system down 2.6.29.6-smp Sun Feb 21 12:39 - 13:20 (00:40)
reboot system boot 2.6.29.6-smp Sat Feb 20 09:39 (1+02:59)
09:39 until 12:39 the next day is 1 day 02:59.
The time in parentheses at the end of the shutdown lines is normally the time until the next shutdown.
So far so good. The incorrect output is for the last reboot and shutdown of an old wtmp file. Here's the output of last /var/log/wtmp -x reboot shutdown; last -f /var/log/wtmp.1 -x reboot shutdown
Code:
[snip]
reboot system boot 2.6.29.6-smp Fri Mar 12 07:42 (01:54)
shutdown system down 2.6.29.6-smp Fri Mar 12 01:31 - 09:37 (08:05)
wtmp begins Thu Mar 11 08:25:26 2010
[snip]
reboot system boot 2.6.29.6-smp Wed Mar 10 14:12 (15+01:42)
shutdown system down 2.6.29.6-smp Wed Mar 10 12:41 - 15:54 (15+03:13)
[snip]
The boot started at "Wed Mar 10 14:12" which had an actual uptime of 1 day 11:20 is reported as 15 days 03:13 which is the time from then until the last -f /var/log/wtmp.1 -x reboot shutdown command was issued. The time from shutdown to shutdown is similarly affected.

I'm new to Ubuntu and have spent several days trying to make a few simple alterations to my Myth 9.10 installation. My biggest task was to get the MCE "power" and "start" buttons working, which they now are - sort of.
The problem is with the shutdown command that the power button activates seems to be different to the shutdown command from the taskbar shutdown menu i.e. when I switch off the computer with the remote it restarts with the "recovery" menu as it wasn't shutdown properly. Same thing happens with the shutdown command from a terminal window. Shutting off from the desktop menu is fine.
