I made a little applicaton in MonoDevelopit works fine and does what it's supposed to when I run it inside of MonoDevelop itself.butwhen I try running the output exe file from either the debug or release folders it just won't do anything...s is because my system assorts exe's with wine or is it something else?I can't really figure it out...and now we're at it is there a way for me to change the output format in MonoDevelop??? I pretty much just got it
I have just installed the package monodevelop on Ubuntu 10.4 and wanted to try it out.I'm a long-time .NET developer using Visual Studio 2005/2008 on Windows so I'm familiar with the concepts.I created a new Gtk# project in MonoDevelop, but the empty project already won't compile because almost all referenced assemblies are missing. Here's the build error messages:

I am brand new to openSUSE (coming from Fedora then Kubuntu then Linux Mint) and I must say I am very impressed. Unfortunately I am also a C# developer and I need Mono (and more specifically MonoDevelop) to function correctly. I installed MonoDevelop from YaST and started with the simple "Hello World" command line project that is included by default. I then added Tarball packaging to the solution and attempted to build the package. It spit out the following error:
"Package creation failed. Object reference not set to an instance of an object"
I then tried double clicking on the Tarball package in the solution and it gave me an Unhandled Exception error dialog with a stack trace. Does anyone know what could be causing this problem? It's as if I am missing a required package or something. I have tried to install automake but that didn't change anything.
i'm trying to run some code i had written a couple of weeks ago in windows :$, the program has to create and copy some files and when i try to run this code in monodevelop this error:Unhandled Exception: System.UnauthorizedAccessException:Access to the path '/tmp' is denied.i've tried to change the path where i know i have read/write permissions but it doesn't seem to work, the code was originally written to create a file in the Temp folder in windows.
I have a project built on Silverlight 2.0. I installed Fedora 13 (KDE) a few days ago since I'd like to brush my Linux skills after a long Windows-only time.I installed the monodevelop package and it's dependencies. But while building this project I got the following error:
Code:
Error: Framework 'Moonlight / Silverlight 2.0' not installed.
But I can't find a Moonlight package in PackageKit. Does one exists? Should I download it from Mono Project and build it manually?
When i was in Windows, i had absolutely no problem creating and running basic terminal C++ programs. I came to Ubuntu, and now I've got a big problem: I can't run any program that i make. I have tried making programs in Code::Blocks, CodeLight, MonoDevelop, and NetBeans. All 4 four are free IDE's from the ubuntu installer. I've created 4 programs, 1 on each, and they're all the EXACT same program. When i build it, they build just fine and run. When i release and compile it so it becomes an .exe program, i can't open it. I find the thing, double click, and nothing happens. I rightclick and choose Run, and nothing happens. I made a basic Hello World program, and i couldn't even run that. Is there an extra thing im supposed to install to allow me to run .exe or something?
I have a home movie that is currently in Video_TS format (.bup/.vob files). I burned the movie using K3b and it works awesome in both Ubuntu and on my DVD player with the television. BUT the thing will not play in XP! I understand this is because XP is the work of the devil, but that is not important. The disc shows 4Gb used (in XP) but only gives the title. I even made sure hidden files were visible, just in case somehow the movie was invisible. I have tried burning my DVD directly from the video_ts files in K3b, and first making an .iso file, then going over to XP to burn the DVD using Nero...annnnnd same thing. I can watch them on the TV and 'buntu but not XP.
What have I done wrong? Advice? Need more info? invariably someone wants to ask the irrelevant question "Why do you need to watch it in Windows?"
Back in July I bought an Acer Aspire ONE KAV60 with Xubuntu installed on it. I used to run Linux a long time ago but had not messed with it for a couple of years and I was surprised to find out how much more "user friendly" Linux had gotten (With Ubuntu anyways). There are more and more GUI programs/processes now days which makes everything easier to do, however there are a couple of things that I have found in the last few months running Linux only on my little netbook.
When I downloaded Ubuntu 10.04 LTS Lucid and installed it from the Xubuntu, I was quite satisfied with the general desktop setup and ease of the operating system. I loved it, it was like going from OS/2 to Win95 all over again! (I'm not that old, I just started young). Here recently, I ran into a little problem with 10.04 and had to re-format, but when I went to re-download it the new 10.10 was available instead. I threw it on a flash drive and installed it on my netbook only to have "problem after problem" upon installation and had downloaded and installed 10.04 from the archives in a matter of a few hours after messing with 10.10.
There were plus sides and down sides to both right off the bat. I am a nerd I suppose and I have started to play a game called Runescape. After installing 10.10, I opened up Runescape and was able to use the "Re-sizable" screen option! That's an amazing option with Runescape on a netbook. I then opened up my favorite and most used program suite called aircrack-ng. I had the apparently infamous problem titled "fixed channel mon0: -1" and was completely unable to get it working (even after reading the SOLVED article on here.) I spent probably 2 hours trying to figure out that problem and was unable to do so. I cannot be without the aircrack-ng suite so I decided to revert back as I fore mentioned.
Upon reverting back to Lucid LTS from the archives, I was happy with the smoothness of how it runs on my netbook compared to 10.10, but as soon as I logged onto that damn game Runescape, I was on a mission to figure out how to correct the "fixed channel mon0: -1" issue on 10.10 so I could have the re-sizable screen option again.
I finally figured out that I needed (from a fresh install on 10.10) to do apt-get install patch and apt-get install gcc before I could complete the steps of the SOLVED issue guide. This was never mentioned and it made me realize I still need to know what I'm doing if I'm going to run Linux and then maybe I won't have all these issues.
Out of all this, I have a couple of questions and would like to learn more about Linux so I do not have these problems in the future. Here are a couple of questions I would like to mention first: What is gcc? I had all that trouble just because I didn't know to install gcc to do the tutorial.
I believe the re-sizable screen option is available for me in 10.10 and not 10.04 because of Java. I did not have to install Java in 10.10 at all, I just opened up Runescape "out of the box". In 10.04, I use Sun Java with the apt-get command in Terminal. Does anybody have any information to confirm or deny this?
Once I got aircrack-ng working in 10.10, I was surprised to find out that it is amazingly fast compared to 10.04. I believe this has to do with drivers. I was able to use aircrack-ng (after install) "out of the box" with 10.04 so I did not download the "compat wireless" drivers that had to be used in 10.10 to get it to work.
If I were to revert back to Ubuntu 10.04 (I much prefer Lucid for my netbook, runs much better), would I theoretically be able to download a different Java and use the re-sizable option on Runescape? Would I also be able to use the "compat wireless" drivers in 10.04 to make aircrack-ng send and receive arp's and ack's so much quicker?
Last but not least, I would like some sources if possible to better learn Linux from. I mean Terminal type Linux, I do appreciate (as I said earlier) the new GUIs that are available now and I didn't have before, but I still feel the need to know my way around the system and I just don't have that knowledge.
I recently installed a base system from a 10.10 alternate cd and then selected a few packages to build myself a light install. I'm using lxdm as my login manager (desktop manager) and openbox as my window manager, with lxpanel and nm-applet autostarting after loading openbox. that's it so far.
My problem is that almost any changes I make as a user are not saved. ie I tried to make a wireless network available to all users with network manager but it immediately reverts. I tried to make changes to permissions through the gui 'users and groups' tool, (with i installed visa gnome-system-tools package in synaptic) but all changes are immediately forgotten. I also cannot mount another partition using pcmanfm. I get the response 'authentication is required.' These sound to me like permissions issues. what groups do I need to be a part of? update: I checked my groups and I wasnt a member of any so I googled around for whats normal and added myself. Im now a member of the groups:
Code:adm disk dialout cdrom sudo audio www-data video plugdev games users fuse lpadmin admin netdev But still nothing. changes are not remembered.
I had burned a DVD in Windows Vista from a friends home and then tried to brows it on my Ubuntu 10.4 System. But as soon as i pop in the DVD I get an error alert saying:
Quote:
Unable to mount UDF Volume Error mounting: mount: block device /dev/sr0 is write-protected, mounting read-only mount: wrong fs type, bad option, bad superblock on /dev/sr0, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so
So i later tried to mount from command line and got the error.
Code: sudo mount -t udf /dev/cdrom1 /media/cd mount: block device /dev/sr0 is write-protected, mounting read-only mount: wrong fs type, bad option, bad superblock on /dev/sr0, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so
Is there a way to permanently mess up a pre-made dvd? i would like to be able to mess up a dvd through software, that way there would be no proof of tampering. (i want a few new movies on blueray ) i would like it to run in ubuntu, but a windows program is fine. these are factory dvds btw, not dvdrw.
I'm running a virtualised backupserver. This makes backups to an LVM volume on the host. /dev/mapper/system-backupserver is put through as a block device to the KVM-based, libvirt-managed backupserver and there it's mounted (obviously) rw.
I've also mounted the same volume, as ro, on the host, so as to get at my backups more easily. So now the same partition is mounted on two different machines, both thinking they've got sole access.
Now when the backupserver VM alters the contents of this partition, it sees this happening normally on its df report, but on the host machine, this remains mostly unseen. I tried doing a mount -o remount, but that doesn't help, although umount/mount will do it.
Meanwhile I seem to be able to get at all the data just fine, and it's just the total used/free that gets out of whack. Is there any way to regenerate/reread those totals without doing a full umount/mount cycle?
How come mozilla lightning did not made into the repos for Lucid? My only chance is to download it from mozilla? I am using Lucid 32 bits. So. I did it, downloaded lightning-1.0b1-tb+sm-linux.xpi and installed fine: Code: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.1.9) Gecko/20100423 Lightning/1.0b1 Thunderbird/3.0.4 However, none of the calendar functions are working, calendar itself opens, but no grid lines are displayed. When I click on an invitation for an event, nothing is shown as body, no options to accept or decline, and the message is not marked as read. How can I workaround it? I tried mozilla daily ppa but no luck, erased .thunderbird profile, no luck. What else can I try?
Against my better judgement (since it's an MLC device) I ran scrub on the free space of my SSD, which writes dummy data to all the remaining space on the drive and then deletes it. After I ran it, I went from 250MB read to 267MB (the original benchmark when I first got the drive). I just depleted from the drive by writing all that data to it
I backed up my windows hard drive using dd and turned it into one huge image file. I didn't realize this beforehand, but this image is not an ISO equivalent type. However, it would be nice if I could access everything on the image just by mounting it instead of having to transfer it back to /dev/sda or something.
I recently installed Acetone ISO in the hopes of installing a program, but alas it doesn't do what I need it to (run the MDF file like a disk rather than showing all the files in it, and because this is a multi-disk thing I'm installing I'm kinda stuck now) and I noticed it would make a new virtual drive every time I mounted an image, and I wound up with four of them, and each one had its own shortcut on my desktop. Well, I removed the program and deleted the folder it created, but these shortcuts are still on my desktop. And they are UNTOUCHABLE!
The command line ls -al ~/Desktop/ will show everything on the desktop BUT THEM, they have no permissions, and cannot be moved, copied, or deleted, because Ubuntu can't find volume information on them. I reinstalled the program to see if anything would help, and I noticed that the drives would go away if I unmounted the image (I coulda sworn I told it to before, but it didn't want to...) but now these drives are errors to the program, and I still can't remove the shortcuts.
I have a dvd that was made on windows and acidrip rips about 75% of it then stops.All others that was made on ubuntu ripped but not the one made on the windows pc.Can someone tell me how to rip it or maybe a software better then acidrip.
I recently installed Ubuntu 9.04 and later it got updated to 10.04 via automatic upgrades.
Previously, I having Windows. My HDD had 3 partitions. I installed Ubuntu in the C drive of Windows partition, left D drive as it was (in NTFS, because it had crucial data), and wanted to extract some part of E to be used as Swap. I marked E to be used as swap, but it took all of the drive as swap space, and later when I corrected it so that it takes only 2 Gigs and went ahead with the install, it made that partition unusable.
Maybe because it doesn't allow more than 4 physical partitions.
I am attaching two screenshots of Disk Utility results and Disk Part too.
So I just found out how to install Ubuntu, and found something wrong. I made a partition for the install and when I went to install it, it already had 4 partitions. The recovery and other stuff, so that means the partition I made cannot be used. D: How do I fix this?
My computer originally had Vista installed on a sata hdd, and I added a second hdd (IDE) to install Ubuntu 8.04 and had been working great. Everything installed easy. few months ago I downloaded and reinstalled 9.10. That also worked good. I have been telling others about how well it has been working for me. I haven't had any trouble fixing any of the minor problems that I did come across like playing encrypted dvds.Well last week I upgraded to 10.04 using update mgr and it wanted to update grub. so i went ahead and let it.
after rebooting to Ubuntu (which is now a little slower than 9.10), the login screen page was shifted to the right. everything else was fine after logging in. windows also booted up ok. I found some info on a forum that helped me change resolution for grub, and I think I may have done more custom changes that I read online. everything seemed ok until this week. I try to boot into windows but after selecting the windows loader, the page just goes black and does nothing (cpu fan is working hard and doesn't slow) im not sure if i moved grub to wrong partition or if its configured to boot the right windows partition.I have two partitions on sata hdd. one is just the windows recovery. the IDE has Ubuntu only.
my old pc died not long ago so I retrieved its hard disk and bought a USB enclosure. that HD had a ubuntu 9.04 partition and an XP one. Something must have gone wrong somewhere as, although i could still boot from jaunty, I was not allowed to upgrade.
It therefore seemed to me natural perform a clean install, so here's what I did:
- on a win7 computer, I inserted a 9.10 bootable disk
- with usb-disk creator, I wanted to install via a spare image so re-formatted the HD
- I couldn't install a mythbuntu 9.10 after that as I giot an error message ("can't mount the drive" or something similar). yet, in win7 the HD is recognised.
So, what am I doing wrong? Are USB HDs not included as USB devices that you can make bootable? Or should I be installing a !straight" ubuntu version, then install MythTV?
I have a HDD that I was using as temporary storage (ext4) though I knew it was close to failing. Upon retrieval of the data, I found some of it was corrupted.
I unmounted and ran gddrescue on the whole device (/dev/sdd) using this command:
Code:
The image took ~24 hours to complete, and I can mount it using:
Code:
Of course, some of the files are still slightly corrupted, so I would like to fsck on the image to try and correct anything that can be. However, when trying this on the image, I get:
Code:
Here are some other interesting pieces of info:
Code:
gpart finds no useful info it seems, and trying to fsck using the -b option and the backups suggested by mke2fs results in the message above or (using a very high block):
Code:
As I said, the image can be mounted and the filesystem accessed. Many of the files seem ok and can be directly copied off of the mount, but I'd like see if some can be recovered or at the very least copy everything off the image, skipping the corrupted files (perhaps with a log of those skipped).
None of the data is critical and will be ok if lost, but I'd still like to try recovering it just as a proof of concept. The original disk can still be used (very slowly), but I'd rather recover the data only using the image if possible.
Alright I have just got done installing Ubuntu 10.10 and Lamp, now I know I need to move all my website files to Var/WWW. Well there is a little problem, when I try to delete the two test pages or even edit them. Ubuntu tells me i do not have permission. And what confuses me the most is i installed the damn OS and i was the first account made one it i am an admin and i still cant delete
