I did an update-grub but it didn't work. To do bootrec, I'd need to be able to use the console from the Windows 7 DVD, but remember that no menu appears, it just shows the background and stops...

Ok, from Super Grub I can get to Win 7. But the problem persists: when booting from the Hard Drive without any help from Super Grub, the PC reboots, and, in Ubuntu, I can't access my Windows...

Hello. I'm using Windows 7 and Ubuntu in two differents partitions in my hard drive. I was on Windows 7 and decided to reboot. When the grub screen should have appeared, instead the computer rebooted...

Hello. I installed the alsa-driver from this page: http://www.alsa-project.org/main/index.php/Download. After that, I got no sound. I tried running alsamixer but it said "cannot open mixer: No such...

Hello. I have a NVIDIA graphic card which became damaged yesterday. I had to remove it and now I'm using my Intel GMA 3100 which came with the motherboard. Everything works fine, but when I try to...

It gives me Segmentation Fault in either case. Perhaps the solution is somewhat similar but I can't see it

Hi. Let's say I have to strings in C:


char *c1 = "Hello";
char *c2 = "Bye";

Hi. I installed Ubuntu 9.04 with the intention of dual-booting with Windows XP (SP3). I have a 500GB Hard Drive and chose to install Ubuntu "side by side" with XP, giving Ubuntu a little less than...

I wrote the programs as you did and everything worked fine. Thank you!

I'm not exactly sure if there's some overwriting involved but here is what's happening exactly:

This is the reader program:



#include <stdio.h>

Hello. I wish to have two processes communicating with each other by named pipes. I create the named piped in process 1 using mkfifo(), and then I open it in process 1 and process 2. Process 1 shall...

Thank you. You were right, I needed to set up a signal handler for the process that was receiving the signal. Also, I know that other ways of communications such as pipes are better, but I was...

This is the signal handler function:

void signalHandler (int sig) {
printf ("PRINT\n");
}

This is where I install the signal handler (I do this in main):

signal (SIGUSR1,...

Hi. I'm having quite a headache trying to communicate two processes which have no relation (one is not the child of the other). I use SIGUSR1 for this purpose. i just want to send one signal from...
