I want to be able to start a movie on my ubuntu 10.4 machine and then hand it to my daughter (it's a netbook). Is there a program (or setting) to lockdown the keyboard and mouse so she can't change the movie?
Obviously there would have to be a hidden password or something.
After a 4 to 5 minutes after a succesful instalation of Ubuntu 10.10 the mouse and keyboard freeze. I increased the memory and installed a 500 gb hard drive and still have the problem. a second problem. How do I find this post after a day or so.
View 9 Replies View RelatedI am running Ubuntu 10.4 and using Virtualbox very intensively to develop under windows. This is the perfect combination: Virtualbox is excellent and gives great speed, functionality and connectability. However, I keep getting a keyboard and mouse 'lock-up' and find that I have to power-down my PC in order to get things working again. The strange thing here is that Ubuntu seems to continue working fine: for example audio keeps playing and the system once successfully finished burning a CD even though keyboard and mouse were frozen.
This happens only very sporadically but is a serious problem because I can't have things freezing when I am in the middle of development or am demoing functionality to a client.At first I thought it was Ubuntu but it only seems to happen when VirtualBox is running so I am wondering whether there is a problem with the keyboard and mouse capture for Virtualbox and that this is causing the problem.I have de-installed and re-installed Virtualbox but this didn't help.So does anyone have a idea how I could either fix this problem or how I could get the system to free the keyboard and mouse when I get a lock-up.
Running Landmarq Intel Atom DC330 Desktop I have just attempted to upgrade my desktop machine from Kubuntu 10.04 to Kubuntu 10.10. I used KpackageKit to do the upgrade which proceeded smoothly until the install packages phase, which seemed to complete and then repeat. I don't know the detail of what happened as I was out of the room.
The repeat almost completed, but then I got a set of error messages, which basically told me that KpackageKit was unable to install the upgraded packages. I closed KpackageKit, and closed the machine and tried a reboot. This time, I got as far as the splash screen, but although the cursor flashes, I can't type anything in the password box. In addition, the mouse pointer won't move. Using a different wireless mouse works, but I still can't type in a password.
However, the command ctrl+alt+sysrq+RSEIUB works, so the machine is accepting some keyboard input. I also know from using a live disc that my home directory is intact. I would like to revert to my 10.04 installation, and re-try an upgrade to 10.11 afterwards.
I'd lie to leave the display intact and updating while locking the keyboard and mouse. Ideally, a password would unlock the keyboard but hot keys would work as well. Is there already software to do this? Or a Gnome "screen saver" that doesn't effect the monitor?
View 1 Replies View RelatedI've been using Mint9 on my Laptop from some time, so far so good. However one problem troubling me from some time, is whenever I lock the screen and then unlock it, the mouse pointer/curser gets locked for an indefinite time. Then there lefts no option for me except a forceful shutdown/reboot.
In fact, for the synaptic touch-pad that my laptop has, I always have to press fn key + f8 twice to unlock the mouse pointer at every start up but even the same trick doesn't work in my above mentioned problem.
I have a doubt about signals in C programming. I have done this little program to explain it. It creates a child process with fork and, when the child ends, receives the SIGCHLD signal and wait for its termination.Ok, quite easy, BUT when I execute this code the SIGCHLD signal is received twice, first as an error (returns -1) and the second one to finish the child process.I don't understand the meaning of the first received signal. Why is it generated? Is the code wrong? (if you add the SIGINT and press Ctrl+C during the execution it also receives two signals instead of one)
Code: #include <stdio.h>
#include <unistd.h>
#include <string.h>

I am troubleshooting something and I got this problem.
If I do "pstree -p"
It shows,
Code:
[code]....
However, it does NOT show up in "ps -elf"
Code:
ps -elf | grep soffi
0 S whho 7734 1 0 80 0 - 36435 - 11:14 pts/2 00:00:03 /usr/lib/openoffice/program/soffice.bin -splash-pipe=5
0 S whho 7833 7759 0 80 0 - 751 - 11:21 pts/3 00:00:00 grep soffi
I was wondering if 7735, 7736, 7737, 7743 were really processes. Then I checked /proc, I could cd to /proc/7735, /proc/7736, etc, but I could not ls them out. I looked at the man page of "pstree", it says,
Code:
Child threads of a process are found under the parent process and are shown with the process name in curly braces, e.g.
icecast2---13*[{icecast2}]
So, what does all this mean? Does it mean that 7735, 7736, 7737, 7743 are just threads but not processes? If so, why could I cd to /proc/<id> but not see them in "ps -elf".
I upgraded from 9.10 to 10.04. The Caps lock indicator on my keyboard is not working (always off). The Num lock indicator works fine. I have the same problem with other keyboards. The other keyboards work with Windows & DOS. This isn't a show-stopper, but I'd like to get it corrected as it's problematic when typing in passwords, etc. that have hidden fields.
View 2 Replies View RelatedI just upgraded to 10.04 (and a new machine) from 8.04 and I can't seem to find a way to have the middle button on my mouse act as a double click like I had it on my old machine. I tried putting the input stanza from my old xorg.conf but then X would not come up. The new tab thing it does in Nautilus is driving me nuts. I see the xorg.conf isn't really used anymore, and there is something about making rules in udev but I can't seem to find the exact wording that I need to make that one rule. I would also like to disable the CAPS LOCK key if anyone knows how to do that without xorg.conf. Maybe someone can point me to a udev tutorial?

Had xp before on the Dell, but I don't like it. We're a Mac family, but if this works ubuntu could change our minds!
View 1 Replies View RelatedI purchased a lighted keyboard, on the net.
Black LED Lighted Keyboard W-9868BK USB
The scroll lock key is the key that turns the back light on/off. Num light works/caps light works, but the scroll lock light does not on F12 or Ubuntu Thinking it may be a soft ware problem after trying different usb slots, I dug out an old XP machine and it works.
I've got myself a a Filco Majestouch Convertible 2 which is a USB/bluetooth keyboard.
When I use it in USB mode it works perfectly. I would like to use it in bluetooth mode and I've found that it has problems. When I hit either Numlock or Capslock it stops responding.
I'm running Debian Testing and it was last updated a few days ago (02/05/2015). I've tested the keyboard using Ubuntu 14.04 live cd and it worked flawlessly even hitting Numlock & Capslock didn't stop it.
If I run btmon to monitor the keyboard it shows that after I've hit capslock or numlock it still sends signals to the computer. So there is information being sent to the computer but these characters do not make themselves to my application. I'm just testing with a terminal window.
Here is the output from btmon whilst the keyboard is connected and working:
Hitting the 'a' character

When I running fedora the caps lock & shift LEDs blinking continuously and system was hang.
View 1 Replies View RelatedI keep starting up Fedora and I'm not able to get far (although it's not always at the same time) before my screen will go black, except it shows the mouse/cursor - but it's frozen, and thhen the caps-lock light starts blinking and I can't do anything or get it to recover. Sometimes it happens after 30 seconds, sometimes 40+ seconds and sometimes within 15 or so seconds.
How do I stop this and diagnose this?
I've tried, in the boot-startup to choose an older kernel version, butt the same thing occurs!
I have:
Fedora 11
Kernel: 2.6.29.6-217.2.16.fc11 i586
Asus EEE PC 1002HA
One other thing, it does always seem to happen after I've turned on wireless. And I've been using F11 for months now with no issue.

View 1 Replies View RelatedI'm running fedora 13 on a Dell Latitude E6500. It's a dual 64-bit system.
It was working, but then I tried to swap caps lock and control.
I used:
System->Preferences->Keyboard
Layouts->USA->Options
Then, under Control Key Position, I selected swap caps lock and control.
Now, my keyboard won't work in the Keyboard Preferences test area or in any other window or when the screen-lock comes on.
I tried logging out. I tried rebooting. I tried deleting my .gnome2 directory. Nothing seems to work. I can use the keyboard on other accounts, so the keyboard is not the problem.
I installed the new 9.12 cat drivers in the usual way (init 3; rpm -e the old drivers; generate new rpm; rpm -i new drivers; init 5), but instead of starting like I expected, I got a blank screen and what appeared to be a hard lock (keyboard lights don't toggle, Ctrl + Alt + Backspace and Ctrl + Alt + F1 don't do anything).
I switched back to radeonhd, but I'd like to get the proprietary drivers working if possible.
The usual listings
Code:
[nathan@ebisu ~] lsmod | grep fgl
fglrx 2323096 0
[nathan@ebisu ~] modprobe -l | grep fgl
extra/fglrx.ko
Looks like the driver loaded OK...
Code:
[nathan@ebisu ~] dmesg | grep fgl
code....
Consider the following code:
Code:
int main()
{
int i=0;
pid_t pid;
for(i=0;i<2;i++)
[code]....
I get the following output:
Parent: chid_pid=4356 i=0 parent's pid=4355
This is child 4356 i=0
This is child 4357 i=1
[code]....
I can observe instead of two children(as I expect) processes there are three. This is because child process 4356 creates its own child. Why all the messages of the type "This is child X i=Y" are concentrated one under another? How exactly fork works? Is affected by the fact that I have a dual-core processor?

(I'm putting a computer in my car running Ubuntu and have decided to do away with both the mouse and keyboard and control it from a joystick on the steering column. This has been wired to the circuit out of an old keyboard to mimic the arrow keys on the numeric keypad.)

View 2 Replies View RelatedI just upgraded from 9.10 to 10.04 using the distro upgrade feature. Everything was upgraded without errors.
However, my mouse/keyboard now freezes after 10+ minutes of use. Both are unresponsive, and the keyboard lights does not change with the use of caps-lock, etc.
The system didn't crash though. I had a download running which was completed despite the mouse/keyboard hang.
The computer is barely usable now, I really wished I didn't upgrade...
I'm having some weird problems with my mouse and keyboard. I'll be moving the mouse and keyboard about and all of a sudden the keyboard won't respond and the mouse moves and is fully working, but it seems to be a problem with the desktop, more then the mouse, because it'll highlight stuff and certain stuff will open when I click them, but when I go down to the toolbar, and try to click applications, places, and system, it'll highlight it but not respond when I click it. This happens about every 45 Minutes, to 1 hour of time with ubuntu running [10.04] [Additional details]
- I'm using an HP Pavilion Dv6000 Laptop, 64 Bit Ubuntu 10.04
- My drivers are all up to date
- Could it be because my Laptop gets really hot? But it dosen't happen ever when I'm running Windows, so I'm not so sure about that.
what I can do to configure one of the keys in my keyboard to act as the left click? having mouse issues at the moment.
View 5 Replies View RelatedSo my computer was slow with Karmic Koala, so I tried upgrading my build to Lucid Lynx 10.04.
Now I can't login because neither my keyboard nor mouse (and touch-pad) work. However, I can access the command mode (terminal?) though through the grub boot menu.
how I can get my mouse (and touch-pad) and keyboard to work with Ubuntu 10.04? My machine is an Acer Aspire 4730Z. I dual boot with Windows 7, and I'd prefer not to have to clear out the partition for Linux and reinstall.
