Programming :: Detect Keypress Without Needing Return?
Oct 21, 2010I'm witting a piece of code that needs to read key presses. However I cannot use them as stream, but rather need discrete reads. The code is to simulate an io board interface. So When I press say "d" I need to read it in instantly, not wait for return. I've tried sdl, but no luck (I'm reading in a thread and it causes some problems) I'm using linux so can't use conio.h functions, I've tired gatch from cureses but this still waits for return.So in C/c++ is there a way I can read instant key presses.

Fedora :: Modify Ioctl TIOCMWAIT To Return The Same Thing That Ioctl TIOCMGET Returns?
Jul 4, 2011I want to modify ioctl TIOCMWAIT to return the same thing that ioctl TIOCMGET returns. Currently wait returns an int of zero or -1 when a change in status occurs. Why not make it return the new status?
This will make the operation faster by not requiring another call to ioctl.The extra call requires 2 to 16 uSeconds to complete on my x64 laptop. How would I make this proposal to the kernal people?
Ubuntu :: Run Fsck On Keypress During Boot?
Jan 4, 2011I am wondering if there is a way to manually trigger a file system check during boot by pressing/holding a key. Maybe there is already a keyboard shortcut built in to do this?I know that using tune2fs you can modify the number of boots (mounts) between file system checks, or even use "shutdown -rF" to reboot the system and force a file system checkAlso, I do not want to force the user to choose to run/skip the file system check during boot. For example, prompting the user with, "Do you want to run a file system check [y/n]?" each boot (or even each time the system thinks it should run a file system check),s not desirable

Ubuntu :: Simulate Keypress Via Keyboard Shortcut?
Feb 21, 2011I have a G15v1. After going through hoops and loops to get it working only to discover that you only needed to install g15daemon through the Ubuntu Software Center, I found myself with one big problem. I migrated from windows just now, and there, I had my macro keys(the extra ones) bound to CTRL+W, CTRL+T and to a simulated mouse-wheel scroll so I could navigate the web more easily. How would I go about doing that? I figured, if I used the System->Preferences->Keyboard Shortcuts thingy and bound my key, in my case XF86Launch5, to a command similar to "simulate keypress CTRL+W"(I know it's totally wrong, just to give you an idea), I might be able to get it working again. Only problem is, I can't find anything like that. Any of you has any clue about it? I googled but I only find C++/Java/coding related results, which are not exactly what I need to do.
View 4 Replies View RelatedUbuntu :: Grub2 Waits For Keypress After Failed Boot?
Jan 6, 2010Last week I installed minimal Ubuntu Karmic with XBMC live on my HTPC. I'm connecting to my fileserver thru a wireless interface and although that works like a charm most of the time, every once in a while the interface doesn't come up during boot and the PC 'hangs'.
I then press ctrl+alt+del and the pc reboots and the Grub2 boot menu appears, I suppose because the previous boot didn't go well. However, the boot menu doesn't have a timeout, I have to press <enter> to continue booting. My wireless USB-keyboard isn't working at that stage yet, so I'm unable to continue.
This is my /etc/default/grub
Code:
GRUB_DEFAULT=0
GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT="10"
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash xbmc=autostart,nodiskmount,setvolume loglevel=0"
GRUB_CMDLINE_LINUX=""
How can I get it such that Grub always times out, even after a failed boot?

Oct 9, 2010OS: Centos 5.4
VNC Viewer Free Edition 4.1.2 for X
Switching between two instances of VNC viewer in full-screen mode takes three key presses and two mouse clicks. How can the viewer be configured to pass a special key combination to the host operating system instead of the remote OS, so it's possible to switch between full-screen viewers in one key press?
e.g. With the default configuration, if I put the viewers in adjascent workspaces, then the sequence to switch is: F8 MouseClick Ctrl+Alt+Left F8 MouseClick If the key combination Ctrl+Alt+Left was passed to the host then it would be possible to switch workspaces (and therefore viewers) in one key press. When working on multiple remote machines, both physical and virtual, it's often necessary to switch between them frequently. I must switch over 100 times some days. Simplifying the key sequence would be both quicker and more intuitive.
General :: Execute A Program Based On A Keypress From A Specific USB Keyboard?
May 4, 2011I've been given one of these ubiquitous usb-sleep buttons which is basically a supersimple usb-keyboard. It's a big button that sends a SLEEP keypress to the computer when you slam it. But that is pretty boring. I'd love to remap it to do something more fun but I can't figure out how to bind to only the sleep press from the button and not from my ordinary keyboard.
The button identifies as
Bus 001 Device 035: ID 1130:600d Tenx Technology, Inc.
I'd like to know if there's either
a way of mapping a key from a specific keyboard to an action OR a way of remapping the sleep key from a specific keyboard to a new key-code or something like that.
Fedora Hardware :: RIGHT ARROW / INSERT Accidental Keypress Stops Mouse Buttons From Working?

I know I know, I should stop hitting those keys by accident, but it seems to happen at least once a day! This is on Fedora 12.

Feb 13, 2010I'm using Kubuntu 9.10 and I have a problem with my screen. I use the nvidia driver downloaded from the website, installed manually as I always do. I wanted to update it, but when I press ctr-alt-F1 to go to the console to stop kdm, I cannot see the usual black screen, but only a very strange blinking screen with lines and colours, strange symbols like $ & %. This happens for every F1 until F6, then F7 luckily brings me again on the graphical desktop.
I tried to install the drivers from the "Hardware drivers" manager in Kubuntu, but nothing changed. I don't know if it's an issue related to the kernel or to the driver. But I don't know how to update it without F1 console, and however it's a serious issue because I cannot do anything in case of desktop failure. The kernel is the last officially released (I don't use the proposed repos), that is 2.6.31-19.

Ubuntu :: PDF File Shows Math Symbols But Printer Does Not?

I have an HP Laserjet 2200 connected via USB with 64MB of memory. When I print page 2 of this document (for example) [URL] the delta-symbol and minus-signs do not show up, although I see them in Adobe reader version 9.3.

I'm testing these on the 2 computer. local and my vds. They both have Ubuntu 10.04. On the local machine all works fine, but on the vds it doesn't take chinese symbols. Where can I find the difference between machines configurations? I suspect it depends with X server configuration.

View 3 Replies View RelatedProgramming :: GDB (No Debugging Symbols Found)
Oct 19, 2010I'm running gdb across a network using gdb server. I've got it up and running. However I can't see any source or variables for my code (in ddd /gdb). At start up gdb says (no debugging symbols found). I've got a g in my make file,
CPFLAGS = -Wall -Os -g -pedantic
I've tried loading symbols in using "symbol-file testarm", this sort of works in that I can view symbols but not names, e.g. if I ask dd to show x y and z, rather than
x = 10
y = 20
x = 30
It says:
display
10/20/30
Also ddd does not show anything in the source window, is there a way I can get it to show this? I think it's because I've started ddd with ddd arm-linux-gdb, as I'm calling a crosscompiler gdb. So can I tell ddd to point to the correct folders? What commands I need to set in gdb/ddd to view variable names (it's hard to keep track when it bunches them all together) and how to view my source code.
Programming :: Parser Symbols With Different Types
Nov 27, 2010I decided to try making a programming language again after my last unsuccessful attempt, so now I figured how to write a good AST and it works great when the nodes are hard-coded into a test program. But to make a language out of it, I need a parser to build the tree according to an input file. I ran into a problem here:
YACC input file:
Code:
%{
#include "nodes/allnodes.h"
#include "Node.h"
int vars[26];
%}
%token SEMICOLON INTEGER VARIABLE IF WHILE DO OPAREN CPAREN OBRACE CBRACE
%right ASSIGN
%left NE
%left PLUS MINUS
%left TIMES DIVIDE
%% .....
As you might see, each nonterminal creates a Node* object and uses it as its value. The problem is that the literal tokens, however, don't return Node*'s and I don't know what to do. I would like to be able to convert literal tokens to nodes in the Lex file (which would avoid the problem), but the problem is with the assignment operator, which takes a Node* for the right-hand side and a variable name (not a Variable Node, because they just evaluate the the variable's value and you can't change the variable with them) for the left hand side.

To solve this I put sylfaen.ttf in /home/darksaurian/.wine/drive_c/windows/Fonts and this magically fixed the problem. I don't know why or how I figured it out. But now with Slack 13.1 I do the exact same thing, same version of wine, and the font trick does nothing. The mf, mp symbols remain unchanged and unreadable.
