I'm just installed ns 2.31 in my cumputer:fedora 12 (this is the first time working with ns2 and fedora) but I don't know commands to run an example of tcl script and show the graph in my screen.
View 9 RepliesI long while ago (when I was in collage) I used VIM a bit. I have not used it since and would like to get back into using it. I remember there being a way to split the screen within VIM to show common commands on the bottom portion of the screen. I've searched a while and cannot find how to set this up.

My question is related to the log in screen in Fedora 11, Gnome desktop, installed on my laptop. I currently have an account with the name Octav. When my computer starts-up i have a window with <my name> and <other> showing to choose from. When i click on my name, i type my password and i'm logged in.
Now my question, can i have my log in window, without my name written there, so i have an extra security if i may say. What I want is for me to type my username and then password to log in. I don't want my name been written on the screen.
I was wondering if there was a way to show all current actions I am doing in a terminal window? For example if I left a terminal window open on one of my desktops, could I make it display everything I am doing so that when I receive some general error in a program, I could jump over and get some more details. I could also use it to see what commands are actually run when I do certain things.

View 2 Replies View RelatedI just installed the latest updates for Fedora 14, and a restart was necessary so I did. Then, it didn't reboot! It hung when the cursive Fedora "f" was there for about 15 minutes. I had guessed that maybe it was doing an automatic fsck disk check, but I'm not sure.
Anyway, I couldn't change to tty2 etc while this was happening and for all I knew, the system was frozen. Is there a way to see the load progress (the text) while booting?
FYI, after 1 extremely slow but eventually successful boot, everything is back to normal with rapid boot times.
I have an ATI Mobility Radeon x1800 graphic card and I am trying to install it to Ubuntu 10.10. I managed to install Ubuntu with nomodeset but the resolution was very bad and that's why I am trying to install the ATI drivers. I have deleted the xorg.conf file, installed the ati drivers through package manager and changed nomodeset to radeon.modeset=1 but when I am trying the commands glxinfo | grep render and glxinfo | grep vendor they don't shown the ATI drivers and the resolution is still bad. Does anyone what to do?
I am providing the results for the 2 commands above.

I'm wondering if there is an option to not show specyfic user on login screen in my gnome desktop - so f.e. I've got 3 users: "a", "b" and "c" and I want only "a" and "b" to be shown in login window.

Recently i had migrated from windows 7 to fedora 15. i have lot of flipbooks with me and unable to open those flipbooks in fedora. finding a suitable solution to open those flipbooks. is there a software to open these books linux. in windows there is no requirement for special softwares to open flipbook, since it is similar to flv or swf files. i had already tried with wine. with wine the file is opened but do not displays the contents or pages, show a blank white screen. @people who dont know about flipbooks: flipbooks are flash objects usually created from pdf files used for reading, flipbooks simulate the reallife book actions(page turning).
View 1 Replies View RelatedI just installed Fedora 12 on a rack computer. I know my screen has the ability to show 1600x1200 pixels. But I don't know what my video card can do. Right now my screen is stuck at 800x600. When I had Fedora 11 I remember it could go to 1024x768 or maybe a little larger. I can't really find a driver for the ATI RageXL, How to make the screen resolution as high as possible.

View 2 Replies View RelatedI have several screen sessions running, one of them named 'test'. I want to send a simple command to there without attaching the screen, so I do:
screen -S test -X ls
But when I attach the screen to see if it has done something, nothing is different... How can I send commands then? Of course the 'ls' command is not what I want to do, but it's just an example in how this is not working.
I'm running a Counter Strike 1.6 Game server on my centos 5 VPS. I can get it to run by simply switching to the directory, then doing: ./hltv Now, when I do that, it obviously closes when I exit Shell. So I do the following and it gives me errors then. screen -A -m -d -S hltv ./hltv My question is, do I need all of those commands after screen? I just simply want it to not close once I exit Shell.

View 3 Replies View RelatedI am learning linux commands. I just wanted to see what happens when I type
Code:
The screen became blank. Keyboard was not responding. I couldn't do a proper shutdown. I switched off computer by pulling out the plug. When I restarted, I heard a series of beeps (approximately 10 beeps). Then I was dropped to the grub prompt. The problem now is I can not type anything into the grub prompt, because the character 'c' is continously printed across the screen like this:
Code:
I couldn't stop the character 'c' from printing (I tried pressing Esc, Ctrl+C)
The solution is easy. I can reinstall grub from a livecd. Or even reinstalling the entire operating system wouldn't take more than 30 minutes. But I want to know:
1) What exactly happened to grub? What stage does this error belong to (1, 1.5 or 2)? What is the error number?
2) How can running "sudo kill -9 -1" affect grub?
So I pressed ctrl+alt+F3 and now my whole system is basically one big terminal - black screen and only accepts terminal commands. How do I go back to the 'normal' Ubuntu desktop screen? Rebooting only takes me back to the terminal command page described above. I can access root commands with sudo bash and my password, if fact all terminal commands seem to work. Is there a command I can use to go back to the regular desktop?

View 3 Replies View RelatedOS: Windows 7Problem: Want to dual boot Ubuntu and Win 7, but OS screen won't show after POST.I need some assistance in installing Ubuntu 10.10. This would be my first Linux installation, all I have done otherwise was virtualize Ubuntu 9.10.I have tried installing two times now but I can't get the boot screen to pop up for when I dual boot and check my OS.So here is what I did, not ever partitioning a drive before for duel booting:1. Go into Disk Manager and shrink the volume of the main HD by 25GB (I was going to use this for Ubuntu)2. I then inserted the Live CD with Ubuntu 10.10 on it and proceeded to install, however when choosing where to install it, I chose the advanced options and chose the partition that I set aside as free space for Linux (25GB -- 25600MB).
3. I set the boot loader to this partition, as the other partitions are the w7(windows 7) loader and the label of the HD. The partition was labled dev/shd5 or something like that. But when I am done installing and try to boot normally the screen where I am to choose which OS to boot does not appear.Question:What should I do to dual boot? I also tried selecting boot alongside another (or similar) and set the same settings as using the dev/shd5 free space that I allocated (25GB) and placing the boot loader on the same partition, which is not the main partition.I do not want to overwrite the Windows Partition as I have things on there that I will need,
I'm a beginner with Linux. I'm using the version of Ubuntu 10.10 installed in a notebook HP Pavilion tx 2000 (Turion 64 x2). My Ubuntu is 32 bits.
I'm passing for the following situation:
When I turn on my notebook, if it is running on battery (even with the battery has 100% of charge), a login / password screen does not appear, and the screen goes dark and nothing more I can do (that I knew!). So I re-start the machine.
However, if the notebook is plugged into electrical energy (with or without battery), a login / password appears normally.
If, with the notebook plugged into electrical energy, I log in Ubuntu operating system, then great. After loaded the operating system, I can turn off electrical energy and the notebook works normally (only with battery). In other words, just the login screen that is with this electrical energy problem.
I used StartUp Manager in Linux to change to "0" the time GRUB shows the "Select OS screen" now I'cant choose which OS I want to boot. Since WinXP is selected as the default OS, I can only log into Windows.
I've already tried to press the UP ARROW several times when the machine starts up but has no effect and the GRUB selection screen won't show up (This used to work on a desktop PC with GRUB and dual OS's). I'm on a laptop, is there any way to get to the GRUB select OS screen again?
My laptop screen goes blank right after the bios is loaded. Live CDs have no effect either.I installed arch linux to my whole HDD today. Last time I installed ubuntu linux to my whole HDD, the same problem happened.The way I fixed the problem last time was by formatting the HDD with an internal HDD dock and then installing windows with linux dual boot.As I do not want to go through the hassle by installing windows again, and I would be very delighted if anyone had an alternate way. I really want my laptop to be windows free!It seems to me that my laptop is somehow constructed to crash / go blank if no windows partition / boot loader is detected. I have no idea why they would do that, maybe you have a better explanation?
