Ubuntu on samsung 9 series thin laptop

Has anyone tried loading ubuntu 11.04/10.10 on new Samsung Series 9 (NP900X3A). It looks pretty thinner and similar to Macbook Air. Does it has good support with ubuntu ?.





How can I change the folder where VLC stores its streams?

Stream records of VLC (by pressing the red "record" button) are stored in ~/Downloads/.



vlc record



Can this be canged, and how? I couldn't find this option in settings.





How do I get Ubuntu to connect to my Android tablet?

What I'm doing is trying to run a software called gMTP, which is apparently what I need to do to transfer files back and forth to my Android Galaxy 10.1 Tab device.



I've asked about it on the Android SE site, but it seems the problem might be on the Ubuntu side. I followed these instructions to get Ubuntu to support MTP.



However, when I run the software, I get "LIBMTP PANIC" and other errors.



$ gmtp
Device 0 (VID=04e8 and PID=6860) is a Samsung GT-P7510/Galaxy Tab 10.1.
PTP_ERROR_IO: failed to open session, trying again after resetting USB interface
LIBMTP libusb: Attempt to reset device
LIBMTP PANIC: failed to open session on second attempt
Detect: Unable to open raw device?
LIBMTP PANIC: Trying to dump the error stack of a NULL device!
LIBMTP PANIC: Trying to clear the error stack of a NULL device!


It seems that the problem is on the Ubuntu side, so is there something I can do to fix it?





Where can I change the webpage showed by apache?

I have ubuntu 10.10 installed, and when I hit my IP I see:



It works!

This is the default web page for this server.

The web server software is running but no content has been added, yet.


Where should I look to see where this is being served from?



The strange thing is, I just installed nginx and setup a static page that is served on port 80 also (should be conflicting with the default apache that is serving the 'it works page'), when I restart nginx I don't get bind error sayign port 80 is already taken.



I dont' use apache, and don't want it but the default install seems to have it. I ahve no idea where it is, I don't see it in /opt or etc/apache .



thanks!

On version 11.04 Ubuntu I have access to my Wifi, but after I upgrade to 11.10, I can never get wifi at all. If I'm wired then it works, but if I'm not then it doesnt work.





How to access "Applications" menu in Ubuntu Unity Desktop (Ubuntu 11.10)

I've installed Ubuntu 11.10 with the new Unity Desktop. I understand that I can access the classic "Applications" menu by switching to Gnome. However, I was wondering if it's possible to access the menu thru the Unity Desktop. If not, then what is the best way to access the installed programs?





what is a better hard drive to install ubuntu 11.10

I have a 40 gig drive and a 200 gig drive. Which one should I install Ubuntu on, and which one should I use for my normal files ie: music, documents, etc...





easy backup solution from windows to ubuntu server 11.10

Well for the last week I tried setting up amanda on my Ubuntu server 11.10. I should start out by saying that i'm fairly new to Ubuntu. Well I googled and read guides and tutorials and no matter what I kept running into issues all over the place. I'm way too frustrated and ready to quit. Is there something that's easy to setup that can backup my server, backup network shares(windows server 2003) and also help me backup windows desktop clients. Hopefully something that use ubuntu specifically on it's installation guide. For now I setup scripts to backup the shares and stuff on the server, but I would really love to be able to get everything in a single place and be able to backup windows clients.





If a key press doesn't trigger anything in xev, is it still possible to use it for a key binding?

I'd like to register keypresses that aren't visible on xev. These are basically "special" keys on my keyboard. If the event does show up on xev, is it possible to get at?





Virtual box doesnt have files machine and help tab

This is the second time im asking this question because someone had to close my question for a reason which i still dont understand.



this is the original question Why is my files,machine,help tab missing in ubuntu 11.10?



Most importantly, I cannot access the machine menu that should be there but isnt.
I am using ubuntu 11.10 with Oracle Virtualbox 4.1.10



enter image description here



The reason why I am asking, is because I would like to run a USB key inside my virtual box,but since I cannot access machine, I can't access the devices manager either.



Just for your information,ive already installed the guest additions.





Can't suspend on Acer Aspire One 722 using proprietary AMD drivers

I have an Acer Aspire One 722 netbook with a C60 CPU and a ATI Radeon™ HD 6250 GPU. I am trying to decrease the power usage and have tried Jupiter and Powertop, but the lowest power usage has been by installing the proprietary driver. I installed the most recent driver from the amd website (amd-driver-installer-12-3-x86.x86_64.run) and the power consumption is very, but now the system won't resume from suspend.



This site says suspend works (I tried editing the /etc/X11/xorg.conf mentioned, but it didn't fix the issue)

but this site says it doesn't

how to switch beetween users using kde,gnome and unity without enter everytime password only on kde?

I can switch between Gnome and Unity after login without retyping my password, however I have to retype my password when switching to KDE.



Can I switch from Gnome or Unity to KDE without retyping my password? Alternately, is there a way to log in to all three simultaneously?





How to quickly and thoroughly use a LiveCD to test for hardware incompatibility?

Often people wanting to know if Ubuntu will run on a potential hardware purchase are advised to use the LiveCD, perhaps in-store, to check hardware compatibility. For example, this answer suggests drivers will usually not be an issue if they work off the LiveCD, but it also says to test "extensively".



Given that if you do this in-store, you'll have a limited time period to do the testing, what is the most efficient way to test the computer? For example, after running a program like vlc to check video and audio...is it then necessary to try a music player too? What settings should be checked?



Let's assume I am interested in all the usual laptop functions (suspend, hibernate, wireless), in addition to things like built-in webcam, microphone, etc.



Also, if the laptop doesn't have an optical drive (like some of the newer thin laptops), then I would have to boot from USB. Is this just as reliable as testing from the CD? (I feel silly asking this, but I know some laptops behave differently booting from USB, e.g. Apple)





Vaio VPCS136FG boots to just a black screen

Hi all I've recently bought a Vaio S series laptop, in case S136. the problem is that when i try to boot from live disc to install or test, just a black screen appears. the problem, as addressed in many threads, is that xorg can't find the EDID of monitor, thus fails. I've tried several solutions described in several forums, but still no success; except that before trying these solutions, the monitor was absolutely off, but now it has the backlight but it is still black. this is my situation:




  • my vaio is VPC S136 FG with a GeForce 310M.

  • my xorg log file doesnt say any error about the edid file. you can find it in the following.

  • i can boot up ubuntu in failsafe mode with
    1280*... resolution, but it doesnt
    use nvidia driver.

  • I've installed Nvidia driver, version 260.19.06-0ubuntu1.

  • I've recently installed xorg-edgers from the ppa,
    but it just adds a thin line of
    light, up in the monitor.



this is my xorg.conf:

Which Ubuntu-list for feedback on 11.10 to 12.04 upgrade issues?

I upgraded to Ubuntu 12.04 beta2 via sudo do-release-upgrade -d and have identified a few... glitches and issues in the process/script, mostly from an end-user's perspective. There seems to more than one list that might fit, in the Ubuntu-devel- or perhaps Ubuntu-qa- or even Ubuntu-desktop- hierarchies.



I know about Launchpad, Brainstorm, BugSquad, etc, but am looking for the mailing-list where the people who develop this specific process discuss it.



In my experience, asking the person who knows the answer is much quicker than doing your own research. :)



Cheers, Alec.

How to run .sh file

I want to download JDownloader from the internet for Linux. But the file is .sh and when I tell ubuntu to open the file it uses some text editor. I searched Ubuntu Software Store and there was no application to open it. Is there any way I can get it installed?





Getting a new PCI card to work in 11.10

I just installed a new PCI video card on a HP/Compaq Presario sr1010z desktop (AMD64). When I play a video, the colors are right, but when I make it full screen, the video is choppier and worse than before I put the card in.
So I inst alled the latest nVidia through (System Settings > Additional Drivers), and the video smoothness improved, but the colors all became strange, almost like a film negative.



Another question, the audio from the old card is no longer working, and the current card only has HDMI out for any type of audio. Is there a way to do a mix? Meaning, disable the audio in the new card, while keeping its audio, and conversely using the audio of the old one? Or any suggestions on some connector that can split audio/video from the HDMI out to speakers and monitor respectively?



Thanks





When I attempt to remove g++ why does apt-get attempt to install it?

Note: Originally I had a long background explanation leading up to why I was trying to perform apt-get remove g++. I have deleted that as irrelevant after trying this in a clean install of 11.10 (32-bit) and then, after upgrading, in 12.04.



It appears to be a problem only 12.04. Time to change focus and see if this is a reported bug.






I did not find anything that looked related so I reported this as Bug #982716.






While attempting to get rid of a problem compiling Octave I removed all the packages needed to compile Octave so I could then re-install them. While doing this I ran into an unexpected response from apt-get in 12.04.



When I attempt to remove the g++ package, apt-get instead attempts to install g++-4.6. I expected to get the message Package g++ is not installed, so not removed. Why didn't I?

Is there a modern tutorial for setting up SSL on apache2?

I've been running apache2 for ages on my ubuntu server without SSL. Now that I want to have some directories delivered by SSL, I can't find any straightforward tutorials that were written recently. The best I've found is http://vanemery.com/Linux/Apache/apache-SSL.html but it tells me to put stuff in /etc/httpd/conf I don't want to guess that that should translate to /etc/apache2/conf because guessing based on old tutorials has ruined my web serving before.





Creating an icon for indicator applet in Vala

I'm writing a program that uses a panel indicator, and I want to use an icon I've created. I can package the application so it installs my icon in usr/share/icons but I can't get the icon to show up in the panel when I run the program, and the indicator ends up not having an icon. Any advice?

Minimisation animations look strange in Gnome Classic 12.04

When I minimise a window, all but the borders and title bar disappear and I can see the wallpaper. The animations only look strange when I minimise, they're just fine when I restore. I've never had this problem until I updated to Ubuntu 12.04 Beta 2 last night. Any idea how to fix this?





10.04 keyboard randomly stops working. Switch to console mode and back fixes it

AS the title says I'm on 10.04 and sometimes the keyboard will just plain stop working. Mouse still works fine. A quick <Ctrl> + <Alt> + F4 then <Ctrl> + <Alt> + F7 and the keyboard works again.



Is this a known issue? Am I just doing something dumb and not realizing it?



Thanks.





bash terminal/console strange overlapping behavior

I am using gnome-terminal in Ubuntu 11.10 and seem to get long lines overlapping
in the terminal window.



When I copy a long command line and paste it into the terminal, the text gets overlapped
to the start of the line and often covers the user prompt.



If I resize the terminal window, making it wider the overlapping gets undone and everything looks normal. In previous versions of Ubuntu, if a line was too long
it would continue on the next line below.



Another problem I have noticed that may be related, is when using the up arrow key
to show previously typed commands, sometimes instead of the output command line
being replaced by the previous command each time the key is pressed, the lines get
partially merged. A portion of the old line remains, and the next command gets
joined onto the end.



This leftover part of a command is persistent and does not get replaced next time the key is pressed, although the insertion point or blinking cursor is at the end of the
latest recalled command, and the leftover has no effect if I press enter.



Is this problem a bug or some setting that needs fixing?
Where do I look for the cause?
keyboard? gnome-terminal? bash?



Thank you for any help or suggestions offered





Windows on SSD; Ubuntu on HDD

In my System I have a 120GB SSD and a 1TB HDD.
I have Windows 7 installed on the SSD and I partitioned the HDD in 2 Partitions on for Windows programs and files. And one for Ubuntu.



But after I installed Ubuntu beside Windows 7, Grub hasn't recognized my Windows 7 install on SSD.



What can I do now to be able to access/boot Windows 7 again?





Problem installing drivers for Brother DCP-1400

I have a problem installing drivers for my DCP-1400 printer. I am using Ubuntu 11.10 and am new to Ubuntu and Linux in general.
I downloaded the lpr and cupswrapper files from the Brother linux site into my Download directory.

I next run Terminal and switch to the Downloads directory.
At the prompt I type in the following:



sudo dpkg -i --force-all dcp1400lpr-1.1.2-1.386.deb


It asks for my password which I type in and press Enter.
I get the following errors:



(Reading database ... 155195 files and directories currently installed.)
Preparing to replace dcp1400lpr 1.1.2-1 (using dcp1400lpr-1.1.2-1.i386.deb) ...

dpkg: error while cleaning up:
subprocess new post-removal script returned error exit status 127
Errors were encountered while processing:
dcp1400lpr-1.1.2-1.i386.deb


I now notice when I open the Synaptics package manager I get the message:
E: The package dcp1400lpr needs to be reinstalled, but I can't find an archive for it.
E: Internal error opening cache (1). Please report.
Any help provided would be appreciated.
Thank you

best command line tool to join videos

I have used ffmpeg, but with it you have to first make mpg videos then do cat video1.mpg video2.mpg > joined.mpg and then convert to joined.mpg to joined.mp4 with ffmpeg to be able to upload on youtube.
I heard there's mencoder which can join avi files without converting to mpg and using cat command.
I'm making videos to upload on youtube so it needs to be avi mp4 or flv format.
Which tool is the best to join videos from command line?

How do the Software Center / Repositories / PPA's work?

I've been using Ubuntu for a while and have been wondering this for as long. There are several things that I am unsure of, and I'd appreciate it if anyone could help me out. This is what I want to know:

  1. What is Ubuntu's online software hierarchy? In other words, from where does the software come when you install it from Software Center / Synaptic / apt ? Are these methods equivalent?
  2. Who makes the software? I understand that some of it comes from Canonical itself, but what about third-party apps and packages like Chromium or pdfcrack or DropBox? How do companies / developers get their software into the Ubuntu repos?
  3. What is a PPA and how does it work?
  4. Who manages the repositories, and are they the same for all chronological Ubuntu releases and variants like Kubuntu?
  5. Any other insight that anyone wants to share.

Thanks a lot!
