Ubuntu 10.04 (lucid) 2.6.32-22-generic

Intel(R) Core(TM)2 Duo CPU E4500 @ 2.20GHz
Whenever I try running ANY screen recording program, my desktop runs too slow to use. I don't think this is a problem with my hardware capabilities, as I used to be able to record my screen perfectly in Windows, whilst doing multiple other tasks. I've installed the ATi/AMD proprietary FGLRX graphics driver.
I've been using Linux for a good six months now, and I'm loving it. I've recently upgraded from Ubuntu 9.10 to Ubuntu 10.04. When I was using 9.10, I couldn't use ANY screen recording software (Trust me, I tried a lot), as it made my desktop 'lag' so much but I just thought it was a problem with my OS, because when I was running Windows Seven I could record my desktop perfectly in HD, whilst running a lot of other applications.
My computer isn't exactly amazing spec, got a dual core 2.20ghz processor, and 256mb ATi Raedon graphic card.
Since recently upgrading to 10.04, I still can't record my desktop due to 'lag'.
Will this be a problem with my hardware? Is my computer just not powerful enough to record my desktop on Ubuntu? Or is another problem which I haven't even thought about?
I know that pressing ctrl+alt+shift+R enables me to record my screen, but I can't merge my voice with it. Is it limited to video recording without audio? If that's true, how can I merge two separate an audio file with video file (Gnome produces *.webm videos by default)

View 7 Replies View Relatedi want to create a command that can be typed in any old terminal window that would display a message on screen for anyone who typed it. is this possible? i just want to do this for the randomness of it.
and cuz i need to get used to messing with terminal windows.
for example i would like to have "rawr" setup as a command to display a message on screen in a popup window with an "Ok" button to close the popup. i googled it but all i came up with was creating commands to launch applications without having to type the full path/command. not what i'm looking for. thanks in advance!!!
I want to do a screen capture with audio and video. I use Ubuntu 10.04 64-bit.I have now spend about half a day trying various tools, most of which seem to be half finished or abandoned. I have not found any usable docs for any of these.gtk-recordmydesktop and xvidcap will both capture video, but seem unable to capture audio from a microphone. The mic is connected and the sound preferences "input" tab shows the input level jumping up when I speak, so it must be working.
I tried the pulse audio device chooser app to make sure the mic is selected, but the choices for input are DEFAULT and "other", which shows a blank input with no choices.xvidcap multi-frame dialog has dev/dsp pre-selected as the input device, with no other options. It does not work.If I enable audio with gtk-recordmydesktop, it refuses to start and says it cannot open the sound card. There is no apparently no way to do this using the "advanced" dialog which has DEFAULT preselected as the audio input device and no other options. /dev/dsp also fails to start.I spent some time searching google and the forums here, to no avail. So should I give up trying to do this with Linux or is there some obscure method I only need to discover?I prefer xvidcap, since the ogg format output by recordmydesktop seems to be a write-only format.
I've noticed that there are a lot of different programs out there to record your desktop (screencast), and it can be tricky to understand the differences between them, their limitations, and how to use them, so i made a video where i show how to choose between them, what their features are, how to USE them, and how to get the highest quality video from them.

View 3 Replies View RelatedI'm using 10.04, and gnome-terminal GNOME Terminal 2.30.2 . I have irssi running on screen session on remote host. And I've been struggling for quite many days to configure it to produce either visual feedback or ring terminal's bell when I receive a private message or one of those that are highlighted.
My compiz settings window in General tab has 'Audible bell' checked.
My GNOME terminal has 'Terminal bell' checked.
I also added 'set bell-style audible' to my ~/.inputrc
And I also tried to manually load pcspkr module into my kernel.
No of the above helped or at least I haven't been able to notice any difference.
I also used some commands for irssi to produce bell sign.
Whats the code in terminal to reset the video drivers? when i try to boot this is what happens.

I have a favorite REXX program called fv2. When I was a Windows user I had an icon for fv2 on the Quick Launch bar. Click that icon, and the program ran. Now, as a Linux (Ubuntu) user it is necessary to go through several steps to run fv2.
1) Launch a terminal by clicking on the terminal icon at the top of the screen. What's that area called? The GNOME panel?
2) Enter: ~/Desktop/RexxScripts
3) Enter: regina fv2
I run fv2 several times per day and would really like to have the convenience of a clickable icon.
I have a problem in programing pseudo terminal. In the book APUE (advanced programing in the unix environment) in chapter 15.4: coprocess gives an example of using pipe to operate another program, that provide its input and read its output: Figure 15.18. Figure 15.19 is filter to add two numbers using standard IO. The author said that you must flush the IO buffer in the program which are operated through pipe by another program, however, we cannot add fflush to the source code and re-compile the whole program if we need to use it in another process. It said that pseudo terminal can solve this problem, but I have tried in fedora12 with forkpty call and fail. Source code as follows:
The main process:
Code:
#include "common.h"
#define LINESIZE 256
int main()
{
int fd[2];
pid_t pid;
if( socketpair(AF_UNIX, SOCK_STREAM, 0, fd)<0 ) {
perror("create socket error");
exit(1);
}
int master;
struct termios tm;
if( tcgetattr(STDIN_FILENO, &tm)<0 ) {
perror("tcgetattr error");
exit(3);
}
struct winsize size;
if( ioctl(STDIN_FILENO, TIOCGWINSZ, (char*)&size)<0 ) {
perror("ioctl error");
exit(4);
}
setbuf(stdout, NULL);
pid=forkpty(&master, NULL, &tm, &size);
if( pid<0 ) {
perror("create process error");
exit(2);
}
else if(pid>0) {//parent
close(fd[1]);
char line[LINESIZE];
memset(line, 0, LINESIZE);
while( fgets(line, LINESIZE, stdin)!=NULL ) {
write(fd[0], line, strlen(line));
memset(line, 0, LINESIZE);
int n=read(fd[0], line, LINESIZE);
if(n>=0) line[n]=0;
printf("%s", line);
memset(line, 0, LINESIZE);
}
} else {//child
close(fd[0]);
if( fd[1]!=STDIN_FILENO ) {
if(dup2(fd[1], STDIN_FILENO)!=STDIN_FILENO) {
perror("dup2 error");
exit(1);
}
}
if( fd[1]!=STDOUT_FILENO) {
if(dup2(fd[1], STDOUT_FILENO)!=STDOUT_FILENO) {
perror("dup2 error");
exit(2);
}
}
close(fd[1]);
if(execl("./add", "add", (char*)0)<0) {
perror("exec error");
exit(3);
}
exit(0);
}
//parent
wait(NULL);
return 0;
}
The add program reads a line and get two numbers and return the sum of them.
Code:
#include "common.h"
int main() { int n1, n2;
char line[256];
memset(line, 0, 256);
while( fgets(line, 256, stdin)!=NULL) {
sscanf(line, "%d%d", &n1, &n2);
printf("%d", n1+n2);
fflush(NULL); /*the program does not work without this sentence why?*/
memset(line, 0, 256); } return 0; }
I have installed a Virtual machine.I use Virtual Box for the same. My host OS is Windows XP SP3. I have assigned it 500mb of Ram and it works fine. But my problem is that my Keyboard does not work in Ubuntu terminal whilst writing a source code.
When I use the arrow keys it gives me alphabets A B C D. And also when i press a . it acts as a backspace.I have a cordless Logitech Keyboard.I don't know why my keyboard isn't functioning inside the Terminal (& that to only whilst typing in source codes) I have tried changing the Character Encoding but thats not helping.

View 1 Replies View RelatedHow can I make terminal applications immune to terminal emulator close, but still able to use all virtual terminal features?
egin{UPDATE}I want my terminal application remain alive and accessible if I accidentally close terminal emulator. This functionality is provided by screen and tmux, but they have issues with colors and they flush screen.Yes,I can run the shell inside screen, but I do not want the shell remain alive unless there is some other program running.
end{UPDATE}I see this must be something like screen, but without VT100 terminal emulation, something which will just apply whatever application does with "terminal proxy"'s terminal (like outputting something to stdout/stderr or using stty to set terminal options) to the terminal this proxy runs in.
// I know about screen and altscreen on, but it makes either this (screen with TERM=screen):
or this (screen with TERM=rxvt-unicode):
while I want this (rxvt-unicode without screen):
I have figured out that everything looks fine if I compile rxvt-unicode with USE=-xterm-color (in fact vim looks like on the second picture even without screen if I add this USE flag) and set TERM=screen-256color, but I do not like this workaround because it actually changes colors and I can't be sure that it will always change them only this way:
I would like to replace gvim with vim in the terminal. One of the nice things about gvim is that it is able to display text using italics.
Vim allows setting an ANSI escape code for italics (e[3m), but this does not work in gnome-terminal. Is there a terminal emulator that supports the ANSI escape code for italics?

I have Ubuntu 10.04 running kernel .26 installed on my Dell Dimension 2350 with 512mb of memory. The problem I have been having is, When I am using the computer mostly Internet stuff for no reason the monitor will go black then on the screen it will be at a terminal screen, kind of like when you start up the computer, I don't remember what is all on it but the last thing in the list was: checking battery state: OK after that the screen will flash in multiple colors and then it goes into a loop of just black screen than a colorful flash and back over to a black screen. the only way I can fix that is by holding down the power button. this will happen mostly on face-book on the games and just on the profile page, but it does happen just checking my gmail or play solitaire it does this around 4-8 times a day.
