Ubuntu Servers :: USB Drive Not Working - Renders System Unusable
Jul 26, 2011
I formatted a 1.5 Tb western digital external usb drive to ext4 for media streaming on ubuntu-server. I tried FAT32/NTFS before but it keeps unmounting itself for no reason. I tried everything I could find on Google but no luck. After formatting it to ext4, it worked OK for a while but for some reason it has stopped working. Running mount -a makes system unusable indefinitely. It works only if I restart it.
UUID=db261dd6-2edf-4020-a0f5-17613a6e94ea /media/wd ext4 defaults 0 0
Is ext4 not a compatible format for external drive? Since, I have I tried different formats and Ubuntu keeps unmounting them. Should I try a different distro?

After doing the standard sequence to go from 10.4 to 10.10 beta, the system is now unusable.There are no icons and no thees. The GDM login shows a big question mark where a graphics would normally be.When I log into the session, I get nothing: no desktop, no panels. Alt+F2 does nothing, so I can't even launch a terminal that way.After starting a terminal from a virtual console, I can start looking at what's wrong. Metacity crashes right awaywith:metacity:ERROR:ui/ui.c:752:meta_ui_get_default_window_icon: assertion failed: (default_icon)Aborted (core dumped)

I have a problem after running zypper up. Apparantly somehow it upgraded to current factory release.. Problems so farNo networkNo x - session(after a quick hack i have x started but no input devices work)I think there is something wrong with udev and my xorg.confx first complained about InputDevice not being recognised.. I moved away my /etc/X11/xorg.conf and got a quick running session (without input devices, so icannot log on) but after a reboot it gives me a "black" screenWhile troubleshooting is encountered the problem that my network card is not recognised.. This all points in the direction of udev or whatever to be badly configured during upgrade..

I have encountered the strangest bug, filled with so many inconsistencies that I am unable to comprehend why or how it is happening. It has only happened once and whilst it seems to resemble another bug that I found when looking for this one, it is fundamentally different. Here are the facts:1. I am using an Acer Aspire One netbook.2. This netbook is running Ubuntu 9.10.3. It has been running Ubuntu 9.10 since the first time it was released as stable.4. Yesterday, whilst I was engaging in an intellectually stimulating debate through the convenience of Pidgin, I encountered the said bug with the following attributes:The keyboard has the appearance of not working.
But if one applies a lot of pressure to each key, one is able to type.This bug is not resolved by a system reset.This bug does not affect my BIOS or even Ubuntu until I log into the particular account where it first happened.When I log out of the account and log into another one, my keyboard is perfectly responsive.When I log back into the "damaged account", the keyboard is once more unusable.The right click menus do work, in stark contrast to another, similar bug, the report of which I encountered in my search for this one.So, clearly, an undesirable workaround would be to migrate to a new user on my system. This, however, does not change the fact that I do not wish to do this another time if the bug repeats itself. Furthermore, if it is only active in a session of the "damaged account", it is likely that it is a configuration error of sorts, no? I have another strange configuration error on that account. The little icon that allows me to choose to which wireless network I wish to connect is random in when it chooses to appear or not, although the service is active (as I am greeted with a message directing me to click on the non-existing icon in order to select the network...). Yet again, this only happens when logged into a particular user, while other users seem completely unaffected.
What I conclude from this is that Ubuntu's configuration system is pretty erratic and it makes seemingly random yet seemingly irreversible changes to user configuration. I would not even know where to start when faced with reading through different configuration files. Furthermore, I would feel as though my PC were constantly working against me. It is a strange feeling, when I bought it with the intention that we might work together.

I am currently running squeeze with the 2.6.32-trunk amd64 kernel.
If I close the laptop lid the screen will not turn back on and the laptop becomes unresponsive. The only way to get it functioning again is to hold the power button down until it dies.

My mom's computer is no longer bootable. I was thinking of attempting to fix it later on this week and am thinking of doing a chroot and updating via a live CD hoping that an even newer update solves the problem but I have some doubts of success. Does anyone have any information about this issue so that I can be better prepared to fix it? Also, I thought I should mention that I tried the second newest kernel to see if that would make it work. It didn't. The error is something along the lines of having the /dev/diskuuid change. If I'm correct, Ubuntu changed the disk's name and is trying to boot the old name. It's dropping to an initramfs shell (not the regular terminal where you can work miracles ).

I have copied my Windows fonts to /usr/share/fonts/. While I understand that they can't exactly be rendered like they are on Windows, this Verdana rendering looks odd.(CSS style: font-family: verdana, arial, sans-serif;)Notice how that "N" in "Norton" and the "V" in "Virus" look obese? By means of comparison, here's the font viewer's rendering of Verdana:

I've installed Ubuntu 9.04 on my hard drive. The results are worse I keep getting segmentation fault errors, black screens, lock ups, etc. This time I can't get it as stable as on Wubi. It can't stay stable more than 3-4 minutes - then the interface blinks and goes to black screen or shows weird colored strips/squares, locks up or shows tons of errors in the terminal. I did the kernel recovery mode partition check, no errors were found. I installed 9.04 on my harddrive, everything works fine, I log in and it stays great for about 1 or 2 minutes, then it freezes.
It shows the terminal with 'segmentation fault' errors, or goes to black screen and locks up. Alt+SysRQ+B is the only solution and sometimes it doesn't work either. I got Ubuntu 9.04 running through Wubi before and it ran perfectly stable occasionally on few boots. But I can't get it like that on my hard drive installation It just keeps crashing. I did a long memtest (10 tests passed), ubuntu file disk check went fine, my current operating system Windows 7 runs great and another Live CD Linux based system like Knoppix runs perfectly stable. Should it be a driver issue?

I'm using 9.10 Desktop 64bit on a Dell Latitude D830. I have 4 gigs of RAM and a 7200 rpm sata hard drive. Everything works pretty well, video, sound, and network. Flash isn't as smooth as in Windows but I assume that's a Flash/64bit thing and not necessarily an Ubuntu thing.
However, one area of performance still lags far behind my Windows XP experience, and that's disk writes. For instance, when I'm copying a large amount of information from a USB drive or from my Windows partition to my native partition, I can barely switch windows until the task is complete, nevermind trying to surf the Web. I thought that that might be related to the slow performance of the ntfs driver, but recently I have been doing a lot of work with VMWare, and I get the same result when trying to pause virtual machines - it writes a largish amount of information to disk in a short amount of time and I can't do much until it finishes.
Here are some things I looked at based on other threads to try to debug my issue:
~$ sudo hdparm /dev/sda
/dev/sda:
multcount = 8 (on)
IO_support = 1 (32-bit)
readonly = 0 (off)
readahead = 256 (on)
[Code].....
That disk read speed is a little faster than average - several more tests showed it hovering around the 66 MB/sec range. Of the other info, I see that UDMA is on which I understand is good, but if there is something else there that I should fix I don't see it.
I know that my computer can handle these tasks (at least the vmware stuff) without such a significant interface slowdown because in XP I did it with less RAM than I have now. Is this just the way that the linux kernel scheduler fails to account for UI needs?

I had a working ubuntu 10 on my old laptop. Not sure what's happened but now whenever you start any app, the app starts in the foreground, then immediately the desktop gains the focus. This happens all the time on any app that is either already running or started from scratch. Thus making the system unusable.

I just bought a new HP desktop, and I want to install Debian on the hard drive. I ran the Windows program on the Debian CD to start the install.
I selected Manual drive setting, and resized the large C: partition to 50 GB. I want to install Debian in some of the free space, only their isn''t any free space! The 400+ GB I took out of the C: partition is labeled "unusable" instead of "free space."
If I double click the unusable space, I am just given the cylinder/head/sector numbers. How I can make that space usable?
I would boot my Gparted CD, but I don't know how to get to the BIOS. The boot screen goes right to Windows without showing me the key to get to the BIOS. I tried hitting DEL, but to no effect. Do you know what the HP computers use to interrupt the boot?

I have Kubuntu 10.10 64-bit, which was running fine until I did a bunch of apt-get software installs to permit me to compile YaWP weather plasmoid. In the process I am now at KDE 4.6.2, and my system is now non-functional, not able to start KDE desktop.
When KDE starts I get continuous krunner segfaults, krunner is taking 100% of the CPU, the desktop is there but the system is unusable. /var/log/messages is filled with the krunner segfaults, each line further indicating "error 4 in libkio.so.5.6.0". I tried reinstalling kubuntu-desktop, problem remains.
I expect I have created some software incompatibility with my installs, but I do not know how to diagnose/resolve.

I have just found a 120gb scsi drive which i would like to use as my system drive instead of my current 80gb scsi drive. I cannot simply plug the drive in for extra storage as i don't have a spare scsi slot! only have 2 and one is for the dvd-drive
is it ok just to dd the one onto the other? can i do this whilst the system is live? or should i use a live cd? or better still put both drives into a separate linux box?
its currently formatted to ext3.
plus would i need to use any special switches using the dd command? or would it simply be :
Code:
dd if=/dev/sda of=/dev/sdb
just trying to avoid a re-install!

I recently bought a second monitor and I had this set up perfectly fine with two panels on my primary display and one on my secondary. I've now gone away for the weekend (leaving the monitor) and I went to turn on my laptop and it didn't work.
When I login to a gnome session (or indeed a failsafe gnome session) I just got two horizontal white bars (where the panels would be). I switch to a terminal, login and run top and see that gnome-panel is on 100%. Running 'killall gnome-panel' does nothing (tried a few times).
I've had to install xfce4 just to type this message. Is there any way I can 'reset' gnome-panel or any other fix? Or even a workaround would be nice. I'm on 9.10 by the way. I am going to upgrade at some point but its not really an option yet.

My hard drive all of a sudden starts to read and write all on its own for around 15 seconds at a time while at idle or while I am just browsing the net. At first I thought it was from cron running but I have that disabled.

These are the settings on my server, which has a static ip:
Code:
[tim@computim ~]$ cat /etc/exports
/media/cavern 192.168.1.*(rw,sync)
Code:
[tim@computim ~]$ cat /etc/hosts.deny
portmap:ALL
mountd:ALL
rquotad:ALL
statd:ALL
lockd:ALL
Code:
[tim@computim ~]$ cat /etc/hosts.allow
portmap: 192.168.1.2/100
lockd: 192.168.1.2/100
rquotad: 192.168.1.2/100
mountd: 192.168.1.2/100
statd: 192.168.1.2/100
When I try to mount the disk from my client machine I get the error:
Code:
[tim@localhost ~]$ sudo mount -t nfs 192.168.1.10:/media/cavern /media/cavern
mount.nfs mount system call failed
Thinking the problem might be due to iptables I tried the following command as recommended by a book I found on google:
Code:
sudo iptables -A INPUT -i wlan0 -f -j ACCEPT
didn't help so tried disabling the firewall - still getting the error
Both machines are running FC11 - should i be using nfs4?

I am currently running a VPS with Ubuntu Server 10.10. I have been trying for a few days now to get some programs to run when the system starts, but with no luck. I am trying to use rc.local to do this, there is an:
/etc/init.d/rc.local - http://paste.monsterprojects.org/mpbjhwhbjzhbjrr (Was already on the system, I have not edited this)
and:
/etc/rc.local - http://paste.monsterprojects.org/mpbjhwhbkkkhwez
If i run the /etc/rc.local script manually all the programs start fine, and if i run /etc/init.d/rc.local start, all the programs start fine. But for some reason they just don't seem to be starting when the system boots.

I did a routine update of my ubuntu 10.4 (in wubi vista) to the latest kernel (something -26) and installed a java plugin for firefox. After a reboot, i open up the "Ubuntu" entry and i see a message flash accross the screen (something about hda,0,0 or sda im not sure) then it just reboots the PC. No command line or anything. No need to say im pretty screwed
My question is, is there any way to get my files off of wubi? Or even better can i restore Ubuntu to working again? P.S for some reason the two times i have tried to run a live CD on this laptop, it has corrupted vista.

I noticed (in my couple of days Debian experience) that most of my PDF files renders poorly in Evince. And poorly is gentle word to say, as they are unreadable: So I searched Software Center for some programs and installed XPDF, but this program does not belong in my time perception so I ditched it. Then googling, I found Foxit deb package, which shows fine: but I'd like to use something else if possible on Linux system I did not try to install Adobe Reader as I understand it's bloated and slow program, and I felt nostalgic towards SumatraPDF which I use on my Windows 7 OS. I guess there is no hope for such slick PDF viewer on Linux, as I googled as said, but knowing that SumatraPDF's PDF engine is MuPDF, I just feel sorry that developers prefer only Windows version I'm curious which program, experienced Debian users find appropriate for viewing PDF files

I am working on an application that will convert English text into equivalent Indian language text. Since Unicode is the standard, I will be using it. In most of the western languages each code-value directly refers to the glyph index and placing the code-values side by side will give the required display. This one to one mapping is not possible in Indian languages where rendering syllables is required rather than rendering just consonants and vowels. Many of the complex characters are made up by combining several unicode values.
My question here is: How Linux renders this Unicode text correctly? More specifically, what package is used? I believe in Windows they use Uniscribe for rendering.I believe there will be an operating system library for handling the text rendering. Or do I need to write my own rendering engine? How programs like Firefox, GEdit shows unicode text? Do they also have proprietary engines for correct rendering?

I recently installed Debian 5 04 AMD64, when I double-click on any HTML document it is rendered in very large characters.I guess one of the browsers installed (Iceweasel or Epiphany) is selected by default but I cannot find any clue as to which one.What puzzles me most is that I have not yet edited the Apache2 config files to give access to the directories where these files are stored, nor the user etc, and as far as I understand these HTML documents should not yet be available to Apache2 and the browser.

So I'm trying to copy some media from my main hard drive to an external drive.In particular, I'm clicking folders (each containing O(15 GB) in files) and dragging them into a folder on my external HD. Fedora pops up an error message saying there was an I/O error for some of the files I'm trying to copy.So, now, some of the directories copied right, and one seems to have gone haywire. In particular if I navigate to /media/China Disk/TV/Battlestar/ and then run ll, I get the following output
Code:
ls: cannot access Battlestar.Galactica.S03: Input/output error
total 12

I have minor problem with upgrading a hard drive. I am running an old pentium lll with two hard drives. On the first hard drive I have two partitions of around 90GB each. On the first partition is installed winXP and on the second partition I have Suse 10.3, both booted by grub and living happily side by side. My second hard drive (which is formatted for windows is only 4GB.
My problem arises when I try to replace the 4GB with a 80Gb hard drive. When I disconnect the 4GB drive the system fails to boot up and complains with error 21.
