Files in /dev
Hello all I have a simple question - why are there more files in the /dev directory then actual existing devices on a particular machine ? In particular, on start up, why does not the system interrogate the hardware and only create files corresponding to the actual hardware present ? - in order to avoid confusion.

Window Managers for Kubuntu and Ubuntu
Dear All I hope that this does not sound like a big whing but I do not like how the presentation of the later versions of Ubuntu and Kubuntu are going I have been using Ubuntu 10.04 with Gnome interface and I find it very good. Then upgraded to 11.10 and I really don't like Unity at all. I then switched to Kubuntu 11.10 and the interface while better than Unity, is still not as good as Ubuntu 10.04 What are my complaints ?? The philosophy that the computer /should be a functional working tool/ - easy to use, fast in operation and requiring minimal resources. These ideals seem to be being abandoned and the /'graphic arty types' /are taking over. Flashy interfaces ( which of course must be /'original'/ ) seem to be the go, causing bloat, slows down operations and demands more RAM and CPU power. For my part, I am not at all impressed by fancy interfaces - I want a machine which is minimal in presentation, quick in operation, easy to use, in other words /totally utilitarian/ /in design and presentation. / The ideal interface in my opinion is that used by Apple; lots of drop down menus; icons which can be placed on the Desktop if required AND /the tool bar with the sliding magnifier /- truly brilliant !! Does any know of a simple window manager like that of Apple's which can be used to replace Unity - especially the sliding magnifier tool bar I would be quite happy to stay with 10.04 window manger but that will be phased out in the future. Does anyone else out there feel this ? Hope that this does not put too many noses out of joint.

Installing Open Office 3.3.0 in Ubuntu 10.04
Hello All I downloaded the following from 'Ubuntu Geek' - it specifically deals with the installation of OOo3.2, but I have downloaded but not installed the similar file for OOo3.3.0 I now have a file 'OOO330_m20_native_packed-1_en-US.9567' after unpacking. Every thing below is clear except for the number 9472 which occurs in point 4 below - where did this number come from ??? Thanks David ** This tutorial will explain how to install latest version of openoffice in ubuntu You can check what is new in openoffice 3.2 from here http://www.openoffice.org/dev_docs/features/3.2/ First go to the OpenOffice website http://download.openoffice.org/other.html and download the Linux .deb file (On your desktop) 1 - Once you have done that, extract the .deb file, OOo_3.2.0_LinuxIntel_install_en-US_deb.tar.gz Run the following command from terminal or just right click select extract tar xzvf OOo_3.2.0_LinuxIntel_install_en-US_deb.tar.gz Then you'll see a file called OOO320_m12_native_packed-1_en-US.9483 2 - You can remove the existing version of OpenOffice if you wish with this command: sudo apt-get remove openoffice*.* 3 - Copy and paste OOO320_m12_native_packed-1_en-US.9483 onto the desktop then open Terminal and paste this command: sudo dpkg -i ~/Desktop/OOO320_m12_native_packed-1_en-US.9483/DEBS/*.deb 4 - Then paste this command: sudo dpkg -i ~/Desktop/OOO320_m12_native_packed-1_en-US.9483/DEBS/desktop-integration/openoffice.org3.2-debian-menus_3.2-9472_all.deb Once you've done that you'll find OpenOffice 3.2 in Office. -- ubuntu-au mailing list ubuntu-au@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-au

Right click on that icon and select Edit Connections, then select eth0 (or whichever one she normally connects with) and hit the edit button.

Re: Question for GCC programmers
Thanks Lisa for your reply, my requirement I gather is not that unusual.
Since you enlightened me on the concepts of 'raw' or 'cooked'
terminals, I have found several other sources on this as follows:
http://osr507doc.sco.com/en/OSUserG/_How_to_get_a_character.html
http://stackoverflow.com/questions/421860/c-c-capture-characters-from-standard-input-without-waiting-for-enter-to-be-pre.
There are others as well.
I wish to be able to compile the code to run under MSWindows (ugh!) for
friends to use, so the solution must satisfy this.
Thanks again for your invaluable help.
Regards
David Bowskill

Hello Fellow Ubuntu Users
I have been writing some programs using GCC and I wish to have a
program receive a character from the keyboard immediately upon
pressing the key ( not buffered or held until 'enter' is pressed) and
with no echoing to the screen.
Is there a simple way to achieve this?
Thanks in anticipation

Hi David,
There's 2 options for this in C, firstly and probably the easiest is to
use ncurses. Something like this will do what you want:
#include unistd.h
#include stdio.h
#include ncurses.h
#include ctype.h
int main(int argc, char** argv)
{
initscr();
cbreak();
keypad(stdscr, TRUE);
int ch = getch();
endwin();
printf(you pressed %c\n,ch);
return 0;
}
make sure to add
-lncurses
to the compiler command.
Secondly, you can manually set the tty to raw mode, wait for the
keypress, read from stdin, and reset the tty to cooked mode, which
would look something like this:
#include stdio.h
#include stdlib.h
#include termios.h
#include unistd.h
#ifndef STDIN_FILENO
#define STDIN_FILENO 0
#endif
static struct termios termattr, save_termattr;
static int ttysavefd = -1;
static enum {
RESET,
RAW
} ttystate = RESET;
int set_tty_raw(void)
{
int i;
i = tcgetattr (STDIN_FILENO, termattr);
if (i 0) {
return -1;
}
save_termattr = termattr;
termattr.c_lflag = ~(ECHO | ICANON | IEXTEN | ISIG);
termattr.c_iflag = ~(BRKINT | ICRNL | INPCK | ISTRIP | IXON);
termattr.c_cflag = ~(CSIZE | PARENB);
termattr.c_cflag |= CS8;
termattr.c_oflag = ~(OPOST);
termattr.c_cc[VMIN] = 1;
termattr.c_cc[VTIME] = 0;
i = tcsetattr (STDIN_FILENO, TCSANOW, termattr);
if (i 0) {
return -1;
}
ttystate = RAW;
ttysavefd = STDIN_FILENO;
return 0;
}
int set_tty_cooked()
{
int i;
if (ttystate != RAW) {
return 0;
}
i = tcsetattr(STDIN_FILENO, TCSAFLUSH, save_termattr);
if (i 0) {
return -1;
}
ttystate = RESET;
return 0;
}
unsigned char getch(void)
{
unsigned char ch;
size_t size;
while (1) {
usleep(2);
size = read(STDIN_FILENO, ch, 1);
if (size 0) {
/* manually handle Ctrl-C (EOT) */
if (0x03 == ch) {
set_tty_cooked();
exit(0);
}
printf(%c, ch);
break;
}
}
return ch;
}
int main(int argc, char** argv)
{

Suddenly very slow to start
Hello Fellow Ubuntu Users For some strange reason my Ubuntu 10.04 has suddenly become very slow to boot. I tried to repair the system at boot ( pressing escape) and then selected 'repair broken packages'. I have tried the above several times but still keep getting error messages as follows: usb 1-4 device descriptor read/64, error -110 unable to enumerate usb device on port 4 unable to enumerate usb device on port 5 It also thinks that there is a program still running, although it has started from cold.

Re: Suddenly very slow to start
Many thanks to the two David's who replied to me. The command 'lsusb I was not aware of, and with the '-v' switch, provides a mass of data (not sure what it all means) about the USB connected devices. This is the great thing about the Linux (especially Ubuntu) Community - the great sense of camerade and willing help that is shared around. I belong to a 'Mens Shed' and we have a computer club which at present is based on the 'dark' side. My aim is to convert as many as possible to the 'light' (Linux). To this end I am very much interested in what Paul Whipp is suggesting to promote Ubuntu - more strength to his elbow !

If so, try removing that before boot up. There are ways to boot in safe mode or recovery mode or something too, which shows all the startup messages scrolling up the screen.

Peculiar effect with keyboard -solved
Hello All Thanks to all who have replied on this curious problem, for which I have found the cure on the internet. The effect was that I could login on the GDM screen but when Xwindows started, pressing any key would only produce an alert sound. This effect suddenly appeared one day. Postings on the Ubuntu Forum (from where I got the cure) showed a few people have experienced this before. The cure was; within Xwindows press Ctrl+Alt+F1 (worked within X despite the 'alert'). Now in command line mode, run 'sudo aptitude install sandwich'. I would appreciate if anyone could explain to me as to what 'sandwich' is and how it works?

printing control- again
Hello All Does anyone know of a program which can intercept the stream going to a printer, such that it would allow only odd or even (user selectable) numbered pages through to be printed. This would be useful to facilitate double sided printing. Many programs in their printing dialogue require you list the pages as 1,3,5,7 etc,then 2,4,6,8 etc.and don't offer the facility of odd/even printing - although a few do.
