Anyway, I downloaded a package by accident a while ago which provided a graphical display of the filesystem in with cool colored blocks showing the files and directories. Does anyone know what this is called?

I am accessing a firewire camera using the libdc1394 library and saving the image as a PPM file, using the code below:
[Code].....
My question is whether the above code is portable. I presume it is, since the result is a binary PPM file which should be capable of being read across multiple computers with different architectures and different operating systems. But at the same time, all that the above code is doing is just saving the binary representation of unsigned chars on the harddrive, and there does not seem to be any reason why the binary representations of the unsigned chars will be identical across multiple computers.
I know how to manage them from a commandline but I was wondering if there are any graphical partition editors that understand and work with lvm2?
View 1 Replies View RelatedI am very new to linux, and I have a question regarding the filesystem check (fsck). The power recently went out and when I tried to restart linux the following error appears:
*/dev/sda1 contains file system w/errors, check forced it then goes on to say..
*An error occured during the file system check. Dropping you to a shell; the system will reboot when you leave the shell. Give root password for maintenance (or type Control-D to continue) I wasn't sure what to do, but checked some other online forums and they suggested running fsck manually - so I typed in the root password - and used the command, "fsck -A -V ; echo == $? ==" it then gave the following message
*WARNING!!! Running e2fsck on a mounted filesystem may cause SEVERE filesystem damage
*Would you like to continue (y/n)
Again, I wasn't sure what to do so i just checked no. I then manually turned off the computer and was prompted at the beginning to press Alt-3. I was brought to another screen and it informed me one of the drives was degraded and suggested rebuilding the array. I tried doing this, but it still brings me back to the original error of, "/dev/sda1 contains file system w/errors, check forced," and the process continues.
Also, when I tried to rebuild the array, I didn't backup any of the data on our home directory before doing this (which was probably a big mistake). After being prompted to type the root password, I was able to give the ls command and look at all the directories...the home directory where our data was stored was empty and I am afraid I may have lost some information. Is there a possibility that data was lost when I was trying to rebuild using the old drives?
I'm not a Linux noob, but I am far from guru. I'm running a single board computer with a slightly customized Debian Etch (customized by the SBC vendor). No Gnome/KDE/X installed. My application is a control application which uses SDL (Simple DirectMedia Layer) to paint some basic graphics on the VGA. I need to run it as root because the application calls iopl() to access an IO port.If I run my application manually from the command line, life is sweet. From Googling around, I found http://www.debian-administration.org/articles/28, and hence I:1) Created a script in /etc/init.d2) Executed "update-rc.d scriptName defaults" to link the script into the boot sequenceAll very straightforward. My application starts at boot. But when I try to SSH/SFTP into the SBC, I get "Connection refused". So I can't manage the SBC anymore, and this is a big problem. I am not sure if it's relevant, but my application starts before the SSH daemon.My script looked like:
case "$1" in
start)
echo "Starting my application"

I have a following problem: Recently my drive with Ubuntu 9.4 has mysteriously stopped working, i.e. when I switch the computer on it informs me that GRUB didn't find the filesystem. Well, I suppose it happens.
First, I though it was due to the drive dying, but I popped it in an external enclosure and HDTune told me the drive was fine. Wanting to recover the files on the drive before reinstalling I first tried to mount it in said external enclosure under Windows (I have Win Ext2 driver installed which used to work just fine). This time, however, drive gets assigned a letter but upon opening it Windows popped up an error saying that the drive was not formatted and whether I would like to format it then.
Unfazed by this streak of failures I tried to mount it under Linux but, alas, to no avail. I might have tried every single -t operator under mount command but it still won't budge and let me mount.
When I try to boot to OpenSUSE I get the following error during boot-up: unknown filesystem type 'reiserfs' could not mount root filesystem - exiting to /bin/sh$
This only started happening quite recently - before this I could boot to Linux quite happily.
I am trying to mount a file image, like this
mount -o loop /tmp/apps.img /media/apps
But I get the following:
mount: you must specify the filesystem type
I try ext3:
mount -o loop /tmp/apps.img /media/apps -t ext3
dmesg says:
error: can't find ext3 filesystem on dev loop6.
I've also tried ext2, vfat etc. How can I detect the filesystem type of apps.img?
I've had a look at some similar threads but as I'm very new to linux they're already a bit technical for me. Sorry, this calls for someone with patience. I gather from other threads that disconnecting an external drive without unmounting is a no-no, and this seems to be the likely cause. Now the disk is read only and I'm unable to change any settings through the usual control panel on ubuntu. I'm just not familiar with the terminal instructions. I tried to cut and past a few command lines from other threads but I got some warnings that proceding could damage data. Like this one: WARNING! Running e2fsck on a mounted filesystem may cause SEVERE filesystem damage.

He wants to use Linux because of wine, ktorrent, xchat, the virus thing, and because of the gui package manager.

because 'at' is such a common word. i found this bug [URL] but the mentioned work around doesn't work.
i can make at work with command line if i enter the a tty to make the output to.
example of what i do is:
Code:
$ at now

ive edited my xorg and now when i start up ubuntu I cannot see the login interface
View 9 Replies View RelatedRecently my Ubuntu has started dropping to bash shell instead of starting the graphical login. It first asks me login name and password(in the shell) then gives me a command line. I can then type startx to start it. It seems to start alright but that is not how it is supposed to work.
Doed anyone know how I can get it back to default behavior?
I am using 10.04. The grub is working properly but i can't login in graphical environment because the system stops at the ubuntu boot logo. However, TTY is working properly and i am able to login in all the tty [F1-F6]. I think the problem is with xserver but I don't know how to fix it.
View 4 Replies View RelatedI would like to start the x graphical interface without using GDM. I may be using the wrong terms here for x. Maybe it is called xdm or x11 or something.) I have set GDM to login without asking me for a password (I am the only user of this machine.) Sometimes, it still pops up the GDM login screen and if I select "actions" "reboot" (my memory tells me that is what it was,) it will reboot without asking to login, but the fonts are all wrong. If I select "apps" "restart" and it DOESN'T ask for my login, all is OK.
I would like to uninstall GDM, and place whatever GDM uses to start the graphical interface into the /ect/rc2.d startup scripts. I know GDM does other stuff then just logs me in and starts the graphical user interface, and I think I would like to maintain some of that, but I think I would like to manually insert the startup sequence in the startup scripts. Question one, can someone tell me where to look to find out what GDM is doing now so I can attempt to replicate it?
#2, does someone know the startup script line(s) to start the x server and graphical interface without GDM? I think this has bees asked before, but it seems hard to search older posts.
I'm trying to run multiple Graphical sessions. How can I do this? I have read the forum article from 2006 but I get an error when executing startx --:2 [URL]

Fatal server error:

If this server is no longer running, remove /tmp/.X0-lock and start again.

I installed the newest Flash player in an update a few days ago, and now ever since last night, every time I watch a Flash video I get graphics problems. It looks as if the Flash video is stuck in the centre of the screen and if anything black (text, notifications) are in the way, they show the video behind them. Hard to explain what I mean Nothing shows up when I run ps ax.
In addition, all Flash videos are now jumbled up with pixels and weird looking glitches.
- Happens with Firefox, Minefield, and Chromium.
- Using latest proprietary NVIDIA drivers available in Jockey
- NVIDIA Geforce 8400m graphics
- Restarting or using Ctrl-Alt-Backspace always fixes the problem.
i saw few themes in some demo videos.in those themes after pressing close button window collapses or breks into pieces.in some themes window closes with a flash light.it gives a look of disappearing.what are these themes called?where can i download them?or can we get those effects by changing settings?

View 9 Replies View RelatedIt used to be that this was a service that could just be disabled in System>Preferences>Startup Services, but this is no longer the case it seems. I've tried tinkering with the runlevels in gdm.conf, but haven't had any success with it so far. I've tried commenting out the startup code in the gdm.conf as well. Also no luck.
Most of what I've found are older guides for Karmic and earlier, so if anyone has a more up-to-date solution for how to disable the gdm so I can auto-login to a terminal in Lucid

View 1 Replies View RelatedI have a really old Dell computer (Dell PowerEdge 1300) that I am wanting to use as a small server (samba file server and apt-cacher-ng). I installed Ubuntu server and then did "sudo apt-get install --no-install-recommends ubuntu-desktop" which was a bad idea because it killed the performance.So here is my question.Ive read you can split the X client and server. Would that let me run a graphical program (like Synaptic) over X without installing any sort of GUI on the Dell?If that is the case, how would I go about doing so?If I would still have to install a GUI on the Dell, what are other options since the on-board display adapter seems to struggle with graphics?

View 2 Replies View RelatedI've been having trouble trying to install ubuntu (and mint linux too) - I have the same problem with either version.
It's an Acer T180 tower PC, when I come to install it'll go through the motions of setting up the drive, copying files and then downloading/installing language packs. Randomly though between copying files and downloading/installing language packs it will just sit there and freeze. Sometimes it will just freeze and stay on the same image, other times it will freeze and what's best described as a window blinds effect will go across the whole screen. Either way the PC stops responding.
I've tried multiple downloads of iso files (ubuntu and then mint) - running on usb and also running from cd and dvd - same issue each time. I've made sure that the username is lowercase too (just in case).
The other thing I've tried is removing the separate nvidia graphics card and using just the internal one (again an nvidia card). Ubuntu will prompt that there are restricted drivers available - doesn't matter whether I install them or not - it still freezes just the same.
