OpenSUSE Install :: System Reboot Fails During 11.3 Installation

Aug 3, 2010

I am trying to update my OS from Opensuse 11.2 to 11.3 using the installation DVD (checked OK). Everything is OK during the installation process until the message "System is going to reboot" is displayed with a countdown : when the countdown is finished, the screen becomes black and the screensaver starts, but the system does not reboot. When I reboot manually, after selecting "Opensuse 11.3 desktop" on the first menu, the screen becomes black and the screensaver starts.

So the installation seems incomplete and I do not know how to finalize it. When I select the failsafe option on the first menu, it seems to work but some behaviours are quite "strange"... When I choose update instead of installation at the beginning, the behaviour is the same.

I do not know if it is linked but the firmware tests started from the installation DVD show the following errors :

Memory tests are OK.

Ubuntu Networking :: Wireless Fails After Reboot / Suspend

Dec 30, 2010

I recently installed Ubuntu 10.04.1 LTS and have it set to dual-boot with windows 7 on my gateway tablet PC. Since installing, sometimes when I suspend or reboot, my wireless does not work. To be more clear - it is working fine, then I either suspend/reboot, then I come back and no wireless networks show up at all. I can still connect with ethernet cable though. I can solve it by rebooting multiple times (usually around 1-5 times) and then it (magically) seems to work again. I have also tried switching from network-manager to wicd, but the problem persists. With both network-manager and wicd, I've tried simulating a reboot for the wireless by using the command 'sudo modprobe -r iwl3945 && sudo modprobe iwl3945' (network-manager) and 'sudo /etc/init.d/wicd restart' (wicd), but these do not seem to work.

Ubuntu Networking :: Bluetooth Keyboard Fails To Survive A Reboot?

Aug 18, 2011

I have successfully managed to connect a Razer Orochi bluetooth mouse with no issues. This also connects automatically when i start up the machine.

I also have a Logitech MX5000 keyboard that i can connect but it never survives the reboot. I have to manually connect it each time.

The only difference i can see between the two is the keyboard asks for a passkey whereas the mouse doesnt.

Ubuntu 11.04 32bit.

Ubuntu Networking :: 10.04 Kernel Update - No Ethernet Connection On Reboot

Sep 18, 2010

I updated to the latest available kernel for Kubuntu 10.04 today (2.6.32-24). When the system rebooted, it refused to connect to my wireless network. So far I have been unsuccessful in persuading it to connect. ifconfig shows the existence of the ethernet connection as eth0, and Network Manager also seems to accept the existence of the ethernet port - so why has it suddenly chosen now to stop connecting to the wired network?

Ubuntu Networking :: Wireless Connection Requires Router Reboot?

Feb 11, 2011

I was having an issue with my wireless connection last week, and sometimes even my hardwired connection. It had seemed like every time my PC went into standby, or any low-power mode, the WiFi would stop working. I used the "power off" command and got it back and running. When I boot up the computer in the morning, I am unable to connect until I reset the wireless router. Unfortunately, I did not have the presence of mind to get iwconfig first thing in the morning, but I did reboot the laptop and grabbed iwconfig before I connected and after I connected. Now, for some reason, the router worked when I rebooted, but I had to reset it this morning. Any ideas? iwconfig below:

****Before Connect****
jake@jake-laptop:~$ sudo iwconfig eth1
[sudo] password for jake:

Ubuntu Networking :: VPN PPTP Connection Fails When Downloading?

Sep 20, 2010

I am using relakks.com VPN Service and set it up with gnome's default nm-manager interface. Everything is just perfect when I'm browsing the web. I can do it for hours and nothing happens. On the other hand, when I open up a torrent client - after 15 seconds to 2 minutes - I get a nice kick off the VPN.

It goes like this:

Ubuntu Networking :: Wicd WiFi Connection Fails / Bad Password Wpa2

Nov 27, 2010

I am running Ubuntu 10.04 on a PackardBell notebook and have just got an Orange Livebox 2 for broadband connection(after years of dial-up as no adsl in my area).I am trying to connect via WiFi to the Livebox to configure, but neither NetworkManager nor Wicd will connect. NM sees the Livebox but simply fails to connect after trying; Wicd says "Bad password".The WPA2 password I have entered is definitely correct, and I have connected without any problem from an AcerOne under Linpus.I have also tried to connect using Wicd and an ethernet cable, and this doesn't connect either, returning "Connection Failed: Unable to Get IP Address"

Networking :: Connection From FTP Client To PURE FTPd Server Fails At MLSD

May 13, 2010

I have a "friend" who hosts a couple of websites that I maintain. I have always used filezilla client to connect and update the files on the website.I lost access for a little while and he said that "The profiles had accidentally been dropped".He reinstated everything but now I cannot complete a log on session. I maintain several other websites which have the same PURE FTPd server at their end and I can connect to these OK.The delicacy of the matter is that, with no changes at my end, and my other sites working, logic suggests that something has changed at his end. I have very patiently worked through all his suggestions but to no avail.I can't suggest that he is at fault when he claims expertise in the field and I am a complete lamer when it comes to FTP.

I wonder if anyone would be kind enough to review the log on result below and see if they can throw some light on the situation for me.(I have anonymised the IP address and other information for security reasons)

Networking :: Cable Modem Connection Fails - Static Route Disappears

Jan 24, 2011

Running Gentoo with kernel 2.6.29 on a Sparc Ultra 10. I'm having problems with my cable modem connection failing, so I've added a static route that enables me to log into the modem's diagnostics page at when the connection drops; my /etc/conf.d/net looks like this (with the comment lines removed).

config_eth1=(" netmask broadcast")
" via"
) dhcpcd_eth0="-N"

This works but after a period of several hours to several days, this static route disappears from the routing table.

Ubuntu :: Wubi Fails On Reboot

Aug 22, 2010

When I try to use Wubi to install Ubuntu it fails on reboot. It seems to run a script on reboot then nothing. I get a command prompt window with the script and the laptop seems to lock up. Only a hard re-boot will restart the system. I do get a dual screen boot prompt Windows/Umbutu but if I choose Umbutu, I get the same command prompt screen and the system is locked up again. Chosing Windows at the boot screen works fine.

Ubuntu :: RAID1 Array Fails On Reboot?

Sep 8, 2010

I did a search and couldn't find anything pertaining to this - if I've missed something please direct me in the right direction We have an Ubuntu box set up as a headless office server (latest desktop install of Ubuntu) and we recently set up two 1TB HDDs in a RAID1 array using mdadm - as far as I can tell it worked successfully and created /dev/md0 with an ext3 file system. After sharing the drive I can see it from the other office computers and could transfer data to and from the RAID array just fine.

I didn't figure out how to get it to automatically mount on boot so I restarted it to see if it would do so by default - however, when I restarted I couldn't see the RAID array any longer on the desktop and it came up as a 0.0kb RAID array in Disk Utility, saying it was broken. It wouldn't let me check it until I stopped and restarted the array.

After restarting I hit "check array" and it appears to be repairing the drives. What have I missed? What happened here? How can I fix it? What other info can I provide to assist:

sudo blkid shows:

/dev/sda1: UUID: "<snip>" TYPE="ext3" (system HDD)
/dev/sda5: UUID: "<snip>" TYPE="swap"
/dev/sdc1: UUID: "<snip>" TYPE="linux_raid_member"
/dev/sdb1: UUID: "<snip>" TYPE="linux_raid_member"
/dev/md0: UUID: "<snip>" SEC_TYPE="ext2" TYPE="ext3"

Ubuntu Servers :: Clean Install Fails To Reboot

May 17, 2010

I'm installing 10.4 x64 on a Dell PowerEdge R610 RAID 1 and the install goes fine until I have to reboot the finish it. On reboot after about a minute it gives the error

Gave up waiting for root device. Common problems:
-Boot args (cat /proc/cmdline/
-check rootdelay= (did the system wait long enough?)
-check root= (did the system wait for the right device?)
-Missing modules (cat /proc/modules; ls /dev)
ALERT! /dev/mapper/mysql1-root does not exist. Dropping to shell!

what to do and my co-worker who knows a little more about Linux can't get it to let him check any of the above common problems.

We're tried letting GRUB manually configure itself at the end og the install before we reboot and we've also pointed it to /dev/sba partition which is what should be the boot partition.

EDIT: in the code tag it's ALERT! /dev/mapper/mysql(one)-root.... the L and 1 look the same

Ubuntu :: Fails To Reboot After Updates Gets Stuck In Grub?

Mar 9, 2010

Just installed Ubuntu a month ago (installed within windows), and for the 2nd time it has gotten stuck in grub upon restart after doing an automatic update. Last time, I reinstalled from the CD, but I can't do that every time. Learning how to start up from grub would probably be worth learning so I don't have to use the CD. But fixing the problem is most important. It makes me wonder if it was a mistake to install Ubuntu from within Windows (does this mean I have "wubu"?). I did find a webpage on booting Ubuntu from grub, but I could not get the kernel to load, regardless of if I used the instructions for wubu or not.

Software :: Sound Fails In SOME Applications Until Reboot?

Jul 28, 2010

I am having a HARD, PARTIAL FAILURE OF SOUND on my Linux system (Slackware 13.1, the latest, with a kernel and KDE 4.4.3). The failure is "HARD" in the sense that once it occurs it remains broken until I reboot the system. It's a "PARTIAL" failure in that it affects ONLY SOME sound software on my system. Here is a list of what fails and what doesn't. (I'm sure there are other programs I could use to test with, but I don't know what they are since I am "just an average user" when it comes to multimedia software.)

These don't fail:

KDE event notification

These do fail:


In the things that fail it is only the sound portion of whatever (flash, mp4, etc) which goes away; the video portion plays normally.n I leave my system up for days at a time. The failure occurs some "long-ish" time (days) after I reboot. I have no idea what triggers it. I do not use sound most of the time, but when I do it's music through Amarok (which doesn't fail) so I do not notice the failure when it occurs.

It seems clear to me that it is NOT the failed programs which are at fault but it is, rather, some underlying set of sound libraries and/or servers used in common by all the programs which fail, and that the failure occurs when something happens which affects that set of sound libraries and/or servers. I don't think this is specifically a Slackware issue since I've seen a few other problem reports on the web where the sound simply stops on non-Slackware Linux systems. Some of the problem reports I've seen suggest that playing sound from one program stops sound from other programs. I've tried various combinations of sound-producing programs but none have triggered the problem.

I've looked at /var/log/{messages,debug,syslog} and see nothing relevant. I've gotten process lists from ps before and after the failure and no "relevant" processes have gone away. (But note, as before, that I am NOT a Linux "multimedia guy" so I can only make intelligent guess at what is "relevant".) Does anyone know what this problem is and, better still, how to solve it? Or where I could look for additional clues? Is there some way to "reset" the sound system without having to reboot?

Ubuntu Networking :: Slow Internet Connection Only With System / Speed It Up?

May 5, 2010

I'm running Kubuntu 10.4, and I'm having a really slow Internet connection, with Windows everything works fine.

When I upload a file to an internal Ubuntu server the speed is ok ~15MB/s.

The problem is only with Internet Firefox / synaptic, any program using Internet. Last download done with synaptic display 18KB/s when normally it should be 500.
