Ubuntu :: 10.10 Environment Acting Squirelly?
Jun 16, 2011
I don't know any other way to describe it. I have Ubuntu 10.10 installed and before yesterday everything was working flawlessly. Then my mouse started acting erratic and after a few battery changes I narrowed it do to adobe. This is because I was experiencing freezes with my desktop as well as my browser. I use firefox as my default and I couldn't open up tabs or even close the browser. Only way for me to close the browser as to use the windows command ctrl d to minimize firefox, right click and close it. After running ubuntu tweak and then update manager I noticed it pulled down a new version of adobe. Everything worked like a charm until today.
Now I have the same problem. I looked to see what updates were being pulled down that could be causing this weird behaviour. The only thing I can figure is jitsi. However, I've never really used this application. It's frustrating to use ubuntu right now cause I can't do any work. This browser is open in another workspace and if I open another application this will freeze. My taskbar is basically frozen so after I post this I'll have to use ctrl d to minimize this and then right click to close it again.

The iso file I downloaded passed the md5sum check. However, the cd I burned from it seems to bypass the usual Ubuntu menu where you get to choose what you want to do (run the live cd without changing your computer, check the cd for errors, install, etc) and it attempts to install itself!! The installation process halts when some sort of error is encountered.

Just like the title, my Ubuntu 9.10 audio acts really weird to me. Sometimes I can't record anything using the sound recorder and the immediate muting of the loud speaker when i plugged in my headphone doesn't work, but then all of sudden it worked and then the problem might occur again. It's like, in some period the audio works perfectly well as if there's not bug, and then it goes wrong.What I noticed is that the problem reoccur when I shutdown/restart my PC and after few minutes/hours/days it works fine again. Does anyone know why this happens and help me solve this problem?

Recently I had (and am still having) a lot of trouble with my Fedora 12 installation.First, 3D acceleration and sound stopped working. This was solver by adding my account to the "video" and "audio" groups (I wonder howcome it worked before?).Then, my keyboard stopped working in X. It would work fine in CLI mode, but as soon as I start X not even the Num Lock LED worked! I think I glimpsed that it might be due to a missing keymap or something, but I don't know. I got my computer back by making Xfce's keyboard settings override X, but it still isn't right, and I can't use anything other than Xfce.Recently I tried to burn a CD/DVD but neither Brasero, K3B, nor cdrecord could detect the DVD burner.

If I right-click a file and select VLC, I get immediate playback from VLC. Everything seems fine until I hit Ctrl+O to select another file. It seems to freeze, but it actually just takes a few minutes to get going.So I opened VLC via a terminal, then hit Ctrl+O,

This just started happening, but I haven't logged out or rebooted in a while, so I'm not sure what could be causing this. I have setup some keyboard shortcuts to use the Win modifier key (Mod4, Super, whatever). The keyboard shortcuts utility in KDE list it as the Win key so that is how I will refer to it. Some example shortcuts: Win+t starts a terminal, Win+m toggles windows maximize mode. I had these setup and they were working fine on this install that I've had for about a month, but they stopped working today. I can still use Ctrl, Alt, and Shift as modifier keys and they work fine.
I open the keyboard shortcuts utility in KDE Control Center (kcontrol) and start to set a new keyboard shortcut. i.e. I click on the button to "build" a keyboard shortcut. I can press the Win key and it shows that it detects it, but when I press the 't' key, the shortcut is just set as 't' instead of Win+t. I can also push shift+win and that shows in the builder but when I press the 't' key, the shortcut is now set to 'shift+t', so it seems like the Win key is acting funky.

I recently bought a pair of Leadtek Winfast DTV Dongle Golds for use in a xbmc/tvheadend based htpc. I'm trying to use the remote, but It appears it is outputting keyboard presses. It also repeats the button presses, as if you were holding down the button on a keyboard, until you press another button (which will do the same), or if you press something on the actual keyboard.
The first issue isn't as mch of a problem, as I can configure xbmc to use it, but the second problem makes it completely unusable.Also, when trying to watch certain channels such as one hd or ten (australian freeview), I get the error "descrambler unavailable".

I have just upgraded from 10.04 (where everything was working fine) to 10.10...I am able to boot in recovery mode (graphic mode is working ok this way), but not in normal mode: just after the purple Maverick boot screen, I get a black screen where my computer stucks, possibly for ever (although I can't be definitive on this point )Do you guys have any thought on what is going on here?I boot once in recovery mode, updated my graphic driver (ati, which was not working well anymre according to catalyst), and then I thought everything would be allright, but it is not the case: still black screen at boot.

On a windows system I installed xampp, and let web applications on the computer be acceseable via internet . On a forum I was firmly instructed that it was an unsecure pracsis.Now I saw on utube, that it is possible to install apache and php on ubuntu 10.04 lts desktop edition.
q1: What shall I install to get apache and php and sql databases?
q2: Is runnings web applications that are acceseable via internet on a ubuntu desktop edition with the above descripted software also unacceptable in terms of security, or is it a productive secure platform. I was told that productive platforms are ok to connect to the internet.

I am pretty new to Linux, but I've been installing it on different systems for a month or so, using different distro's, and this is the first problem where I absolutely can not find a single relevant answer in Google. I recently bought an IBM Thinkcentre and set it up to dual boot Mint and windows xp, it worked great everything works except usb's.
#PROBLEM: The ports only recognize devices of any kind (controllers, mouse, flash drive, external hd) if they plugged in before booting, or if they are plugged in while the computer is sleeping.
- The usb's are recognized normally in Windows XP I tried running different live cd's (Fedora, openSUSE, ubuntu) and they all had the same problem (could this be an issue with the defualt linux 2.6 kernel not working properly with my hardware? if so I dont know what to do next) I reinstalled a newer version of Mint... same problem.

I was working on our PC and screwed up my logical partition. Not much of a concern there but the problem starts when I was trying to repair them. My gparted says that my whole HD is empty. In fact, when I try to install an OS, it wanted to install it on the whole HD (80-G).

We have a nameserver which we moved over from an old server & ip a couple of weeks ago and updated all our dns records.Currently, our dns provider shows the proper records for our server, and if we dig the server at our dns provider we get the results. However, if we ping the server, or dig it and don't specify our server we get the old ip address.An opendns cache check also sporadically returns the proper results from some of its locations but generally returns the old ip address. Does anyone have any suggestions because this bewildering me.

by now I have 10 servers for hpc, power computing oriented. My users need to launch several processes using qmake. The users are used to work with ubuntu 9.10, and the software from the repositories is switable for them. I've deployed ubuntu 9.10 to all 10 servers (pxe rocks). By now we work with parallel-ssh and cluster-ssh, which allows as to launch the same process to all servers. With this tools this tools the servers remain as independent but with the same software and the same launched command. Now we would like to go to next step and see all the servers as a single one with all the resources from the other 9 as if was its resources. The difference would be substantial in time to process and also time to design the command to launch.

I just changed my password now every time I start my computer the keyring wants my old password and it keeps doing weird things even after I type it in. Like Ubuntu will say No keyring found or something to that effect anyway.

All, This is a x-post from the Linuxmint forums. I did this testing on Mint 11 install - but also tried the exact same thing on an Ubuntu 11.04 release and had the exact same output to deal with..Follow along: I'm having trouble with MDADM.... It's not acting like I expect it to.... hopefully someone can enlighten me.
Code:
MintRAID aaron # mdadm --create --verbose /dev/md0 --level=5 --raid-devices=3 /dev/sdb /dev/sdc /dev/sdd
MintRAID aaron # mkfs.ext3 /dev/md0
Added this line to /etc/fstab:[code]...........
I update my fstab with /dev/md127 instead of /dev/md0 and it seems to be working ok.What in the heck is going on? Why all of the naming descrepencies? Can someone help me understand what's going on? I have used the same steps on other (and older) distros and haven't had these troubles. (Ubuntu 9 or 10 something and Cent/RHEL 5.5) I've always named the first array md0, and it's always stayed md0 through reboots, etc etc etc...

after some hard times, I finally managed to have my Orange Huawei E1752 HSPA modem running (a USB modem enabling you to surf the net) the only thing is that I have 2 "problems" with this: I cannot find a clean way to eject the stick when I am done using it. when I want to run it, I plug it, it asks me for the PIN code, which I give, then I do the following manipulations: I first run:
usb_modeswitch
it "creates" 2 files /dev/ttyUSB0 and /dev/ttyUSB1, what I check with:
ls -l /dev/ttyUSB*
then I use the usbserial module to handle the stick: modprobe usbserial vendor=0x12d1 product=0x141b then I check that the stick is working with: dmesg|grep GSM that outputs something like: USB Serial support registered for GSM modem (1-port) option 1-5:1.0: GSM modem (1-port) converter detected usb 1-5: GSM modem (1-port) converter now attached to ttyUSB0 option 1-5:1.1: GSM modem (1-port) converter detected
usb 1-5: GSM modem (1-port) converter now attached to ttyUSB1 option: v0.7.2:USB Driver for GSM modems
finally I choose the "Orange Default" in the list of available connections in the network manager icon on the panel and I am finally connected The thing is, that when I am done, I just go to the same list and then click "disconnect" I go on "Computer" and left click on the SD 4Gb storage (the SD card also in the stick) safely remote drive or something like this. Then I thought that unmounting the device would work,
[Code]...
As a newbie (and especially regarding the use of those modems) I am running out of ideas to "eject" it cleanly, I also checked in the /dev/ file to see that the ttyUSB0 and ttyUSB1 files are present

On my system Firefox 4 seemed to be taking its sweet time "looking up" addresses, but when it found the page it blazed on the render. I poked around on the net and found a few suggestions to speed up the "look up". So I thought I would share... I aimed for the fewest changes, so not to break too many things or make a big mess. (Warning moving and changing things that you don't know about, in the about:config can goof up Firefox so double check your settings) place about:config in the address bar and hit enter
You should get a really long list of things
In the search bar put
network.dns.disableIPv6
My default value was set to false, go ahead and set it to true. Right click and Toggle. Clear out the search bar where network.dns.disableIPv6 was, and put in network.http.pipelining You should have three listings Right click on network.http.pipelining and Toggle so "true" shows for the value. Next, right click on network.http.pipelining.maxrequests and Modify, a box will pop up, replace the default 4 with 8. Close the about:config
Now test your Forefox performance. These three small changes, made a world of difference for me. Its now comparably fast as chromium. If you disagree with what I did, or want to let me know of any other "safe" speedups let me know. PS. If you don't see any improvements performance-wise or your from the future and do use IPv6, it would be best to go and take these settings back to the default Firefox settings.

I'm a new user of openSUSE and just installed it on my HP DV6 computer. I've upgraded to Tumbleweed although the problem exists in base openSUSE 11.4 as well, whenever I'm typing sometimes it seems that a particular key(Most likely the last one) get's sort of "stuck" automatically and gets repeated 10-12 times. This problem did not exist in Windows, Ubuntu or Fedora.

switched recently to 11.2 and it works fine for me as workstation I want to set up a router separating a part of the network and also acting as a firewall/proxy... Configured 2 Ethernet Interfaces, checked Ip forwarding in Yast but it does not forward the packets from the "internal" to the "external" network. Hovewer after I set up my router as default for machines on internal network I can ping the external interface but no adress on external network (particularly the one of the default router) !!! From the router I can reach both networks and the net via default gateway on external. Tried to:
a) switch firewall completely off
b) iptables -P FORWARD ACCEPT
c) masquarading internal adresses to the external network
my interfaces configuration looks like:
eth0 Link encap:Ethernet HWaddr 00:13:D4:E3:A2:7B
inet addr:192.168.1.34 Bcast:192.168.1.255 Mask:255.255.255.0
inet6 addr: fe80::213:d4ff:fee3:a27b/64 Scope:Link

I want to use 2 network cards on a notebook (one internal and one by USB). I don't want the typical "internet sharing", so I want it to act really as a switch:
Other room <== 1Gb/s ==> Notebook <== 100Mb/s ==> network switch with more computers.
I want to do it because i want to use the 1Gb/s link from the other room to the "servers" room, and then the rest of servers will run at 100Mb/s. I wanna all my computers in the same network, like there's no notebook in the middle, so the Notebook will act as a switch (and a server). i wanna (assumming all of this is possible): Code: > [network switch] 1Gb/s
> 192.168.2.1 [router] 100Mb/s
> 192.168.2.2 [wi-fi AP] 100Mb/s
> other room 192.168.2.50 [new notebook] 1Gb/s

I am setting up a server and trying to access its partition over the nfs on a client machine. Our server has 4 1.5TB disks and the idea was to make a RAID 5 out of it.Now here is the problem:When I used only 1 disk that is nfs partition was of 1.5TB, I got fine speed(30MBps), but with multiple disks whether I am making 3TB (Raid 10) or 4.5TB (Raid 5), I get a really poor speed of 5-6MBps. I/O just waits.But for all above cases, disk I/O locally works fine.Does anyone knows any NFS limitation that is causing this problem?

I have an EPIA M10000N (VIA Nehemiah 1GHz integrated CPU) motherboard (square MB each side 17cm) in a GA610 case. These last two links show the situation quite well.I have neither a CD/DVD drive, nor a floppy drive in the case. Only a hard drive, the motherboard, and the power supply.As you can see in the pictures, the whole thing is cooled by a 4cm fan on the CPU heat sink, and another 4cm fan at the rear of the power supply.This is rather noisy (and unbearable in a living room!).After looking (not that hard, though...) for a solution, I did not find a proper (less than 20dB, and good quality) solution. So the living-room PC became a server. It's either that of throwing it away, anyway. Having nothing to loose, I want to try something. And I'd like to have your opinion, dear reader.I want to:
- remove both 4cm fans,
- remove the cover from the power supply,
- cut a round hole on top of the case,
- fit a 12 or 14cm fan on the lower side of the round hole, right above both the CPU and the power supply.
I'm new to this cooling stuff. I saw that a 4cm fan can extract up to 5 CFM of air, whereas a big fan can extract at least 60 or 70 CFM!Changing two noisy 5 CFM fans with a single silent 60 CFM fan seems OK to me.What do you think of the idea?Next, for better reuse, I may buy a Noctua 14cm NF-S14 FLX. It is big and silent, and 71 to 110 CFM seems a lot! And its fixation holes match those of a standard 12cm fan, thanks to the unusual shape
Do you approve?
I still hesitate a bit because:
- the Noctua NF-P12 1300 might be more sturdy due to its regular shape...
- the Enermax Magma UC-MA12 might be a better choice because it can be washed... on the other hand, because of that, it may get loose with time...

I have a Debian 5 system with two nics. eth0 is set up with dhcp-client which will receive a public ip address from my isp. The eth1 will be for my local network and I want to use dhcp-server daemon to serve addresses to my internal network. The area I am confused about is how transmissions are getting sent between nics. I've been told to enable tcp forwarding but I don't understand how that would work since the nics have different network addresses... unless tcp forwarding is basically nat or something..

We have a samba server with a couple of shares defined as follows:
Code:
[Storage]
comment = Storage
browseable = yes
path = /home/samba
writable = yes
[Backup]
comment = Backup
browseable = yes
path = /mnt/hd2/home/samba
writable = no
[Administration]
comment = Administration
path = /home/adm
valid users = adm
public = no
writeable = yes
browseable = no
We have two samba users: samba and adm. The first is used to connect to Storage and Backup shares, and adm is used to connect to Administration share. There are two problems:
1) If Storage and Backup shares are connected to a Win7 box, the Administration share cannot be connected. All we get is an error saying that that share is already connected with different username.
2) We have managed to work around this by connecting the Administration share with the IP-address of the server instead of it's name(?!). The problem then becomes that sometimes connecting Administration share this way makes Storage share read-only. Not always though.
Wrong "security" type in smb.conf (was "user", needs to be "share"). For some reason the Storage share still occasionally gets connected read-only. Win7 also tends to forget the passwords/usernames for some shares upon reboot (not all of them, though).

Whenever I am busy reading or writing large files, or large sum of files, my computer is unresponsive. Screens are getting greyed-out and I just can sit there and wait until the reading/writing is done.
This is not caused by the CPU which is overstressed because it is not. Look at the attachments and you will see the CPU is used for about 20%. When these pictures were captured the computer was using hellanzb to unrar a long list of rar-files.
When you look at my signature you see the computer is not bad at all, just disk-access is slow. I can transfer files with a maximum speed of 30MB/s. Is that normal or is it very slow? I don't know the numbers. I have 2 SATA disks.
O.S. is Mint 9-Isadora, based on Ubuntu 10.04 and I use the 64-bits version.

Just updated, downloads and install complete. I closed laptop. Fan kept running. I rebooted. Black screen. Rebooted again. Screen resolution messed up (800x600 or whatever). Changed resolution in System/Prefs. Better, but the look is not the same as before update. The Gnome fonts and icons are too small, but the resolution is same as before update! My machine has been acting buggy lately...colored text in IceWeasel browser search field, where normally black. I have Firestarter running. How to tell if machine is hacked? I just logged out/in and all normal now. I still think the machine is acting weird.

I have been having some odd issues over the last day or so while trying to get a raid 5 array running in software under Kubuntu. I installed 3 1TB drives and started up, my sd* order got all messed up( sda was now sdc and so on). This wasn't entirely unexpected, so I fixed up fstab and booted again. I found all three of the drives I installed, set them to raid auto-detect and used mdadm to create /dev/md0. I then created mdadm.conf by piping the output of mdadm --detail --scan --verbose into /etc/mdadm.conf.At this point, everything was still going swimmingly. I copied over a few hundred GB of data from another failing drive and everything seemed ok. I went to reboot once the copy was done and everything just went weird. All of the sd* drives went back to the original. Of course, this meant that the mdadm.conf was wrong. I tried to just change the device list, but that didn't work. I then deleted mdadm.conf and rebooted. The drive list stayed in the original order this time, so I just tried manually starting the array.
By erasing the partition table of the 3rd drive, I've been able to get it to the status of spare, but it says it is busy when I try to add it to the array. A grep through dmesg makes me think that md has a lock on it. I'm not sure where to go with it now. If anyone has any pointers, I would like to hear them.
Device List(original):
/dev/sda => boot drive, /home /
/dev/sdb => 1.5TB media storage, failing
