Software :: Kubuntu 11.04 - Enable Playback Of Line-in
May 14, 2011
I can capture line-in audio fine via recording programs, Audacity reads it as "default: Line:0", but I can't seem to find any way short of leaving Audacity constantly recording with software playthrough enabled to actually enable playback of my line-in, and quite obviously that's not a very preferable solution. Any simple apps or terminal commands that would do the trick? Was fiddling with aplay seeing if I could get it to pull it off, but no luck, and I can't seem to find a working device name for VLC to do it. On a small aside, I can't find a way to enable the same with a microphone either.

I have an old laptop that used to run on Vista. It got so bogged down with excess software etc that it was barely running. There was no sound and it was unbelievably slow.
I know its supposed to be more stable (almost uncrashable!) and generally faster so I've done a complete reinstall with kubuntu (I tried a few different distributions with live discs and this was my favourite). All I need it to do is play DVDs - I have a netbook for everything else but the screen is too small for watching movies.
The reinstall worked perfectly and I love kubuntu. The sound now works fine and its MUCH faster.
Except ...
Half way through watching a DVD the system seems to suddenly slow down. The DVD playback becomes choppy and unwatchable and even when I close the player, the whole OS is painfully slow. Programs take ages to open. Even selecting shut down or restart takes over a minute.
And here's the weird part. A restart doesn't fix it. If I restart the system and try to watch the DVD again its instantly choppy. And the whole OS is slow. I actually have to leave the whole system off for a while (I usually give up for the night!) before it calms down.
The laptop is not noticeably hot. Leaving the machine on for a long while doesn't cause problems. It seems to be only when watching DVDs. The spec is not especially low (1GB ram and a reasonable processor) and it doesn't matter whether I use VLC, Dragon or Movie Player.

Using Kubuntu Maverick. It's probably all my fault but I cannot get CD's to play.
Amarok: for the life of me, I cannot understand how to get CDs to play. In Lucid Lynx CD playing was unusable because it would crash by the second or third song; now, I cannot even get the program to start playing my CD.
KsCD: worked in Lucid Lynx, crashes in Maverick.
KPlayer: it does play the CD, but it does so jerkily, that is, it stops every 10-15 seconds. Unusable.
Kubuntu is not a crappy OS that cannot even play a CD.

I've been trying to enable DVD playback ever since last night now and I've been following the instructions on this page: [URL]. And I've downloaded the xubuntu-restricted extras. But every time I run the command:
sudo /usr/share/doc/libdvdread4/install-css.**** works, but Connecting to packages.medibuntu.org|88.191.82.11|:80 always times out. I'm using xubuntu 9.10.

I've installed Ubuntu 9.10 and the prime reason for giving it a go is due to the media center capability with apps such as Moovida and LinuxMce.
Unfortunately during video playback [either divx or flash] there appears to be a random line or lines which flickers on the screen when the video is in fullscreen mode.
I'm using an ATI x1900 video card and have tried using both Tote and VLC, and I have also tried installing the fglrx.
But, both with and without flgrx installed, under the section 'Device' in xorg.conf it says that the driver is 'vesa'.
I don't know how to disable the default ATI driver to enable fglrx, or whether I am going off on completely the wrong tanget and should be looking at something else.
Or is there better support for my type of card in Ubuntu 10 as I don't want to go back to Ubuntu 8 which is the last supported version of the os that ATI developed a driver for my card.

I have been running ubuntu lucid for awhile now and a few days ago added the kde environment. I walked away from the computer earlier to comeback to a frozen screen. So... I did a hard reboot and bios is fine and then I get a blank screen for about 10 seconds, a few things flash very fast( cannot reAd ) and the monitor turns off. I did reboot like a billion times and once was able to get a kubuntu screen that says somehing along the lines of " error initializing .. Files missing. /tmp would you like to fix auto or manual" but igot a response saying cannot fix and it went back to a blank screen. I've rebooted many more times to get this message to appear again, but it fails to do so.... So, after that long story I hope Someone can help. I would greatly appreciate it!!!
Thank you,

I cannot install Kubuntu 8.04LTS. When I run the Live CD and click to install it gets me the box that should show me my hard drives and possible partitions but the box is empty. I get the same when booting to the Live CD and clicking on install. I have had this CD since Kubuntu 8.04 was released. So not knowing what might be wrong I figure I will ask here for what to type in a command line to install it. I know it is an old version but it is the last one with KDE 3.5.

Couple of days I go I setup VLC using Kubuntu's graphic software manager, and installed the 3 plug-ins, one of which was related to pulse. After doing this sound stopped working in flash videos. I had read, not sure where, that Kubuntu didn't use pulse (which slipped my mind when setting up VLC).
So I make the mistake of removing everything which had pulse in it's name (again, via the graphic software manager). A message popped-up saying that some packages needed to be removed/edited (a LONG list, a big clue that I was doing something stupid I guess). I let it run it's course and after that it won't boot properly.
If I boot it normally it hangs at the Kubuntu screen with the five dots filling endlessly. If I press F1 it's stuck at "checking battery status."
Recovery mode boots, but the recovery option does nothing.
So I was wondering if I could boot into recovery mode and go into the terminal and add a live USB as a repository for apt, and try to salvage the install?
Or should I admit defeat and reinstall?

Since I wasn't able to figure out how to enable ctrl alt backspace in kde I thought I would explain how to do it from the command line. Open /etc/X11/xorg.conf as root. Then add this to the file.
Code:
Section "ServerFlags"
Option "DontZap" "false"
EndSection

I'm having problems with my Nvidia card. X doesn't work after installation (9.10), only command prompt. I've read the instructions at http://www.psychocats.net/ubuntu/nvidia on how to enable Nvidia drivers, but the instructions are only for GUI, which I don't have.
Anyone knows how to enable Nvidia drivers from command line ?

I have a Sony TZ270N running Ubuntu 10.04 splendidly. The Sprint Mobile Broadband works great, but it's a bit cumbersome to activate. Specifically, to get it to work I need to:
echo 0 > /sys/devices/platform/sony-laptop/wwanpower
sleep 5
echo 1 > /sys/devices/platform/sony-laptop/wwanpower
Then I wait another five seconds, right-click on the networking icon, choose "Enable mobile broadband", then left-click on the networking icon, and choose "Connect to Sprint Connection". I do this multiple times a day, and it's just a bit of a pain, especially when in a hurry. Accordingly, I'd like to script it so I can do the whole thing with a single command.
I've already put the above echo statements into a script and it works great; is there any way to script the actual start of the PPP session itself -- with the caveat that I'd like the networking icon to accurately reflect the latest state?
(In other words, I don't want to bypass the networking icon and just launch the PPP session in the background -- I want it to show that I'm connected, and still let me manage the connection via the icon after connected.)

I recently installed Deluge 1.2.0 from the following PPA:[URL]I using this on two different Linux computers. One is running Linux Mint 8 and the other is running Ubuntu Netbook Remix 9.10. The first time on either computer when I enable WebUI in the Deluge GUI it works fine. However if I ever disable it in plugins section I am subsequently unable to re-enable it (doesn't appear in the side panel again). Rebooting or reinstalling Deluge seems to have no effect.Is this a bug or am I doing something wrong?

Tri-booting. They were installed in the order I listed above. I ran into a few bugs with Kubuntu, so I no longer want to use it. I want to use GParted on a LiveCD to format Kubuntu and expand my Ubuntu home partition to sit on top of Kubuntu's space right now. If I nuke Kubuntu, will Grub still exist with my Ubuntu/XP entries to boot?

I would like to apply KDE on my Kubuntu because the current one blew up. But each time I to sudo get-apt it seems to be fetching from the cloud. Is there a way I can make it to read from my local Kubuntu CD? I have both Ubuntu 10.04 LTS and Kubuntu Live CDs.
I believe the local disk read should be faster to translate than to bite the bytes across thousands of miles over the wire right?

I have two files, file1.traj and file2.traj. Both these files contain identical data and the data are arranged in same format in them. The first line of both files is a comment.
At line 7843 of both files there is a cartesian coordinate X, Y and Z ( three digits ). And at line 15685 there is another three digits. The number of lines in between two cartesian coordinates are 7841. And there are few hundreds of thousands of lines in a file.
What I need to do is copy the X Y Z coordinate (three digits) from file1.traj at line 7843 and paste into file2.traj at the same line number as in file1.traj. The next line will be 15685 from file1.traj and replace at line 15685 at file2.traj. And I dont want other lines (data) in file2.traj get altered. This sequence shall be going on until the end of the file. Means copy and substitude the selected lines from file1.traj into file2.traj.
I tried to use paste command but I cant do for specified line alone.
Here i showed the data format in the file. I used the line number for clarity purpose.
