Keyboard not working as expected

I woke up this morning and suddenly found a few problems with my keyboard:
The caps lock light is reversed so that the caps is off when the light is on and vice versa
The placement of some of the symbols are moved around. The @ is to the right of the P button and Shift-2 produces a ". Shift-9 is ), shift-8 is ( and many other switched like this.
Resetting PRAM or the computer doesnt fix this

Hello there, morris152.
The following Knowlede Base article provides some great information for troubleshooting your issue with the keyboard:
One or more keys on the keyboard do not respond
http://support.apple.com/kb/ts1381
Particularly:
Some keys don't work as expected
From the Apple menu, choose System Preferences.
From the View menu, choose Speech.
Click the Text to Speech tab.
If "Speak selected text when the key is pressed" is enabled, the key or key combination set to speak text cannot be used for other purposes or used to type text--click Set Key and change it to a less-commonly used key combination (try to use modifier keys such as Shift, Command, Option, and Control). Or, disable the "Speak selected text when the key is pressed" option.
Click the Accessibilty or Universal Access pane in System Preferences, then click the Keyboard tab.
Make sure that Slow Keys is turned off. With Slow Keys on, you need to press a key for a longer period of time for it to be recognized.
In the Accessibilty or Universal Access pane, click the Mouse tab, and make sure Mouse Keys is turned off. With Mouse Keys enabled, you cannot use the Numeric Keypad to enter numbers--instead the keypad moves the pointer (cursor). (There is an option to enable Mouse Keys with five presses of the Option key; you may want to turn that option off to avoid accidentally enabling it.) If Mouse Keys is enabled and you are using a keyboard with no numeric keypad or Num Lock function, see Unable to type while Mouse Keys is enabled in Mac OS X.
If the function keys on the top row of the keyboard are not working as expected, see Mac OS X: How to change the behavior of function keys.
If the issue persists, use Keyboard Viewer to help isolate the issue:
Click the Language & Text pane (Mac OS X v10.6) or International pane (Mac OS X v10.5.8 or earlier) in System Preferences.
Click the Input Sources tab (or Input Menu tab in Mac OS X 10.5.8 or earlier).
Click the Keyboard & Character Viewer "On" checkbox to select it (click the Keyboard Viewer "On" checkbox in Mac OS X 10.5.8 or earlier).
From the Input (flag) menu, choose Show Keyboard Viewer.
If the keyboard is connected and detected by OS X, the keys you type will highlight in the Keyboard Viewer window. Open TextEdit (or any text application), and try to type something using the keys that were previously not responding to see if they highlight in Keyboard Viewer.
Start from the Mac OS X Install Disc, choose Terminal from the Utilities menu and test the keys which were previously not working. If the keys work while started from the Install disc, then the keyboard itself is working correctly. Use How to troubleshoot a software issue to isolate the software issue that may be causing the keys to not respond.
Thanks for reaching out to Apple Support Communities.
Cheers,
Pedro.

[SOLVED] Brightness control over keyboard not working, but it works...

Hello,
I recently got a new laptop at work and I put a fresh Arch on it.
Almost everything works perfectly, but I have one weird issue.
I can control backlight of my display via ACPI; I wrote a simple script for it:
pabre@pbr-laptok:~$ cat /usr/local/sbin/brightness.sh
#!/bin/bash
DEV=/sys/class/backlight/intel_backlight/brightness
MAX=`cat /sys/class/backlight/intel_backlight/max_brightness`
ACT=`cat /sys/class/backlight/intel_backlight/actual_brightness`
MIN=0
STEPS=10
STEP=$((MAX/STEPS))
if [ $1 == "+" ]; then
if [ $((ACT+STEP)) -le $MAX ]; then
echo $((ACT+STEP)) > $DEV
fi
elif [ $1 == "-" ]; then
if [ $((ACT-STEP)) -ge $MIN ]; then
echo $((ACT-STEP)) > $DEV
fi
fi
exit 0
I put myself a sudoers entry for it:
root@pbr-laptok:~# cat /etc/sudoers | grep pabre
pabre ALL=(ALL) NOPASSWD: /usr/local/sbin/brightness.sh,/usr/bin/pacman -Sy
And it works like a charm, when run from a terminal:
pabre@pbr-laptok:~$ sudo /usr/local/sbin/brightness.sh -
So, my next step was to bind that script to appropriate keys on my keyboard (Fn + UP/DOWN - which are XF86MonBrightnessUp and XF86MonBrightnessDown)
My window manager is Awesome, so I put to the config:
awful.key({ }, "XF86MonBrightnessUp", function () awful.util.spawn("sudo /usr/local/sbin/brightness.sh +") end),
awful.key({ }, "XF86MonBrightnessDown", function () awful.util.spawn("sudo /usr/local/sbin/brightness.sh -") end),
among others like touchpad toggling, volume control, etc (which are working without issues)
And now, guess what... Those keys fire that script, change the brightness and after second or less - it comes back to old value! You can see that display blinks (for example gets brighter and moment after - it goes back to previous state).
I tried to debug it, putting to the script something like:
if [ $1 == "+" ]; then
if [ $((ACT+STEP)) -le $MAX ]; then
echo $((ACT+STEP)) > $DEV
cat /sys/class/backlight/intel_backlight/actual_brightness >> /tmp/br.log
sleep 1
cat /sys/class/backlight/intel_backlight/actual_brightness >> /tmp/br.log
fi
And the first entry was that what it was supposed to be, while te other (second after) Was again the old value.
Does anybody have any idea what "reverts" my changes to the /sys/class/backlight/intel_backlight/brightness and why it works without issues when simply run from a terminal?

I think that I've found partial answer.
When I changed key binds to another keys - it works!
But even then, when I press XF86MonBrightnessUp or XF86MonBrightnessDown, the brightness level gets reset. And now they are not bind to anything (at last not explicit).
So it looks that I have to found how to decouple the internal, not working as expected, bind to these keys.

Silverlight 5 binding on a property with logic in its setter does not work as expected when debug is attached

My problem is pretty easy to reproduce.
I created a project from scratch with a view model.
As you can see in the setter of "Age" property I have a simple logic.
public class MainViewModel : INotifyPropertyChanged
public event PropertyChangedEventHandler PropertyChanged;
private int age;
public int Age
get
return age;
set
/*Age has to be over 18* - a simple condition in the setter*/
age = value;
if(age <= 18)
age = 18;
OnPropertyChanged("Age");
public MainViewModel(int age)
this.Age = age;
private void OnPropertyChanged(string propertyName)
if (this.PropertyChanged != null)
PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
In the MainPage.xaml
<Grid x:Name="LayoutRoot" Background="White">
<TextBox
Text="{Binding Path=Age, Mode=TwoWay}"
HorizontalAlignment="Left"
Width="100"
Height="25"/>
<TextBlock
Text="{Binding Path=Age, Mode=OneWay}"
HorizontalAlignment="Right"
Width="100"
Height="25"/>
</Grid>
And MainPage.xaml.cs I simply instantiate the view model and set it as a DataContext.
public partial class MainPage : UserControl
private MainViewModel mvm;
public MainPage()
InitializeComponent();
mvm = new MainViewModel(20);
this.DataContext = mvm;
I expect that this code will limit set the Age to 18 if the value entered in the TextBox is lower than 18.
Scenario: Insert into TextBox the value "5" and press tab (for the binding the take effect, TextBox needs to lose the focus)
Case 1: Debugger is attached =>
TextBox value will be "5" and TextBlock value will be "18" as expected. - WRONG
Case 2: Debugger is NOT attached =>
TextBox value will be "18" and TextBlock value will be "18" - CORRECT
It seems that when debugger is attached the binding does not work as expected on the object that triggered the update of the property value. This happens only if the property to which we are binding has some logic into the setter or getter.
Has something changed in SL5 and logic in setters is not allowed anymore?
Configuration:
VisualStudio 2010 SP1
SL 5 Tools 5.1.30214.0
SL5 sdk 5.0.61118.0
IE 10
Thanks!

Inputting the value and changing it straight away is relatively rare.
Very few people are now using Silverlight because it's kind of deprecated...
This is why nobody has reported this.
I certainly never noticed this problem and I have a number of live Silverlight systems out there.
Some of which are huge.
If you want a "fix":
private void OnPropertyChanged(string propertyName)
if (this.PropertyChanged != null)
//PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
Storyboard sb = new Storyboard();
sb.Duration = new Duration(new TimeSpan(0, 0, 0, 0, 100));
sb.Completed += delegate
PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
sb.Begin();
The fact this works is interesting because (I think ) it means the textbox can't be updated at the point the propertychanged is raised.

Use the trackpad to scroll, thats what it was designed for. The scroll bars automatically disappear when not being used and will appear if you scroll up or down using the trackpad.
This is a user-to-user forum and most people will post on here if they have problems. You very rarely get people posting to say there update went smooth. The fact is the vast majority of Mountain Lion users will not be experiencing any major problems with the OS, or maybe with apps which are not compatible, but thats hardly Apple's fault if developers don't update their apps.

Subtraction of two key figures normalized to result not working as expected

Hello SAP Community!
I am having problems with getting the right result from a subtraction of two KFs which are "normalized to results" which means the KFs really have values expressed as percentages. The substraction that should be performed is of two percentages (e.g.: 87.298% - 85.527% = 1.77%) but my report prints out the result as "number of units" instead (e.g.: 87.298% - 85.527% = 71,514.00 EA). The two normalized KFs actually "point" to two stock KFs, hence the "number of units".
In order to explain the problem I am facing please analyze below text:
1) Let's assume I have below data:
LOAD MONTH PLANT    MATERIAL HORIZON MONTH     FORECAST UNITS
200805         PLANT-A MAT-1            200805         510,235.00
200805         PLANT-B MAT-1           200805          74,240.00
200805         PLANT-A MAT-1           200806         438,721.00
200805         PLANT-B MAT-1           200806          74,240.00
200805         PLANT-A MAT-1           200807         356,981.00
200805         PLANT-B MAT-1           200807          74,240.00
200806         PLANT-A MAT-1           200805               0.00
200806         PLANT-B MAT-1           200805               0.00
200806         PLANT-A MAT-1           200806         510,235.00
200806         PLANT-B MAT-1           200806          74,240.00
200806         PLANT-A MAT-1           200807         438,721.00
200806         PLANT-B MAT-1           200807          74,240.00
2) Then, assume I have a comparison report, restricted by load month for two months May and June 2008 (filter restricted by two month variables) with FORECAST units spread accross columns for whole horizon (two months also in this case).
Material Plant                                 2008/06     2008/07

                   Comparison Units (June 2008) 510,235.00 438,721.00
          PLANT-B
                   Base Units (May 2008)         74,240.00   74,240.00

3) Now, let's suppose we want to know the proportions (%) of Base vs Comparison units, so
we normalize forecats to results an we get the below report:

                   Comparison Units             584,475.00 512,961.00
4) Finally, let's suppose we want to know the deltas (differences) of Base vs Comparison
units, for both number of units and %. The report now look as below:
Material Plant                                 2008/06     2008/07

                   Comparison Units %(Jun 2008) 12.702%     17.216%
                   Delta base vs. comp. units % -1.77%      -2.74%
                   Delta base vs. comp. units         0.00        0.00

                   Comparison Units             584,475.00 512,961.00
5) PROBLEM:
In my report, the "Delta base vs. comp. units %" is not working as expected and
calculates number of units just as "Delta base vs. comp. units" does instead of calculating the % difference.
So my report looks as follows:

b) Delta base vs. comp. units
Delta base vs. comp. units = Comparison Units - Base Units
The KFs
- Comparison Units %
- Base Units %
Are RESTRICTED key figures (restricted to Base and comparison month variables) which
are setup as:
1) Calculate Result As: Summation of Rounded Values
2) Calculate Single Value as: Normalization of result
3) Calculate Along the Rows
The KFs
- Delta base vs. comp. units %
- Delta base vs. comp. units
are FORMULAS setup to:
1) Calculate Result As: Nothing defined
2) Calculate Single Value as: Nothing defined
3) Calculate Along the Rows: user default direction (grayed out)
Thanks for the time taken to read in detail all of this. Long text but necessary to understand what the problem is.
Any help is highly appreciated.
Thank you.

Hi,
The subraction will be carried out before doing the normalization of your KF's. So, it is displaying "number of units". Create a calculated keyfigure and subtract the KF's and in the properties of this calculated keyfigure, change the enhancement as "After Aggregation".
I hope this will solve your issue.

S P.

Events in SubVi not working as expected

Hi, I am reposting this question as my previous one didn't resulted in any satisfactory conclusion.
I have attached my Vi's which are not working as expected. If I remove ONE subVi and its associated 3 controls and two indicators, the other one works just fine, but when I add two SUB Vis, it goes messy. I am trying to learn this way, I am sure it can be done many other ways, but please help me finding out the problem doing it this way as in my final MainVi, I would like to use 8 such sub Vis. Thanks.
Solved!

Your main problem is DATA FLOW. A loop cannot iterate until EVERYTHING in it has completed. So, as you have it, you have to have both event structures execture before you can go back to look for the next event. So if you insist on having these subVIs, they need to be in seperate loops.
BTW, you can get away with a single subVI. Go into the VI properties and make it reentrant (preallocated clone). Then each call of your subVI will have its own memory space. A lot easier to maintain that way.
And I know you said you didn't want alternatives, but here's how you can do it all with a single event structure in your main loop.

My MacBook Pro keyboard not working correctly after Win7 bootcamp installation.
Installation went well but when I boot either with OSx or Win it always keeps Windows keyboard.
How can I have Mac keyboard in OS boot and Win keyboard in Win boot?

Hi - I have the exact same model as your MacBook and had a few questions as mine is acting up. I upgraded the ram to 8gb (2x 4GB ram) and ever since then my computer has not been running as smoothly and the start up time is horrendous. Have you encountered this problem? And if so how did you fix? What would you advise me do?
I was thinking of reverting back to the original factory 4GB then rebooting the entire computer. Any suggestions?
Thanks in advance!

AFS ARUN Size Substitution Not Working As Expected

Hi All,
I need help with this. If any one of you have worked with AFS ARUN size substitution, kindly provide me with some details on how can I set it up. I am specially interested in setting up size substitution with two-dimensional grids.
I have setup some examples but it does not work as expected.
Here is a small example:
Say I have a size 28/30, 28/32 .........29/30....
What I want to achieve is that during ARUN if there is a shortage of stock in 28/30 then the remaining requirement qty should be confirmed from size 28/32.
with my setup after 28/30 it goes into looking for stock in 29/30, which is what I do not want.
Any inputs will be really appreciated.
Thanks!!

Stephanie, thanks for the reply.
I am very sorry to state that I made a mistake.
VAL_SIZE_TO_IMAGE indeed works.
What fails to work is VAL_SIZE_TO_PICTURE. (Second option in Fit Mode attribute in control editing panel)
I tried with JPEG and it's the same.
I am attaching an example.(Load_Image.c & ONEP_3Trow_POS1.JPG)
A panel with two picture rings.
- SW_1 remains at the intended size and the loaded picture is not clear.
- SW_2 will fit to picture size and looks OK.
Appreciate your support,
YOSsi Seter

USB Keyboard not working after running Monolingual

Okay, I'm not a Mac person and should have known that I was going to mess up my mother's iMac, but here it is -
In an attempt to improve the mac's performance I performed all of the actions described in the following article: 11 Ways to Optimize your Mac's Performance ( http://lowendmac.com/eubanks/07/0312.html ). Basically, I cleaned up files and 'other' system preferences. Things seemed to be fine and the computer did run much better. However, after running Monolingual and deleting what I understood to be 'unnecessary' PowerPC files the standard USB keyboard is no longer working.
I've tried to search for various remedies, but have come to a dead end. So I'm left with reinstalling the Snow Leopard OS (I think it is 10.6.8?) BUT I can't because it is asking to input the account password (which I know) to make the change and I can't figure how to do that when the keyboard not working.
Any help would be great!
*feeling like a bone head*

How are you trying to reinstall Snow Leopard? If you're booting from the Snow Leopard or iMac Install DVD that came with the system then that should eliminate any of the issues you may or may not have caused when you deleted did the clean up work on your mom's system.
I suggest trying the following:
0) Verify that the caps lock key is off. It can make inputting passwords difficult if you don't realize it is ON.
1) Reset the PRAM by restarting the system then quickly press the command-option-P-R keys before the gray screen appears. Wait until you hear the computer restarts two times as indicated by the startup chime. For more info refer to http://support.apple.com/kb/ht1379.
2) If the issue persists after the PRAM reset then boot from the Snow Leopard or iMac Install DVD, whichever you have. Once you see the menu asking you to choose a language try using the arrow keys on the keyboard to move the language choice selection. If the arrow keys are working at this point it indicates your keyboard is at least partially functional. Go ahead and select the language then proceed to step 3.
3) Once the next screen appears move the cursor up to the menu bar area and pull down the Utilities menu. Select the 'Terminal' application. Once the Terminal application launches try typing the various keys on the keyboard and check to see if the correct characters are displayed. Please let us know if you detect any errors. If there are no errors then you should be able to quit the Terminal application and proceed with reintstalling the OS.

Notification "Launch the app and go to the library" not working as expected

Hello,
we are sending notification "Launch the app and go to the library" - but it's not working as expected, it's still just launching app with last open folio.
Whats wrong there? Do we need v30 app? We have V29, but this is not mentioned in documentation.
Thanks
Martin

Ah.
Ok, now it's clear.
Anyway i would appreciate possibility to force viewer to switch to library view after new issue is detected, even without notification. Quite often requested feature - "there is new cover in Newsstand, but customer don't know how to download new publication easily".

DB Adapter polling as singleton process is not working as expected

Am using poller DB adapater to control the transaction per seconds to the downstream system and i want this poller process as singleton (One instance should be in running state at a time).
As suggested in oracle documents , below is the parameters configured in composite.xml file.
<service name="polling_Mange_Alert_Events"
ui:wsdlLocation="polling_Mange_Alert_Events.wsdl">
<interface.wsdl interface="http://xmlns.oracle.com/pcbpel/adapter/db/Application1/int_app_manageAlerts/polling_Mange_Alert_Events#wsdl.interface(polling_Mange_Alert_Events_ptt)"/>
<binding.jca config="polling_Mange_Alert_Events_db.jca">
<property name="singleton">true</property>
</binding.jca>
<property name="jca.retry.count" type="xs:int" many="false" override="may">2147483647</property>
<property name="jca.retry.interval" type="xs:int" many="false"
override="may">1</property>
<property name="jca.retry.backoff" type="xs:int" many="false"
override="may">2</property>
<property name="jca.retry.maxInterval" type="xs:string" many="false"
override="may">120</property>
</service>
Below is the JCA file parameters configured :
<adapter-config name="polling_Mange_Alert_Events" adapter="Database Adapter" wsdlLocation="polling_Mange_Alert_Events.wsdl" xmlns="http://platform.integration.oracle/blocks/adapter/fw/metadata">
<connection-factory location="eis/DB/vff-int-fus" UIConnectionName="PT_APPINFRA" adapterRef=""/>
<endpoint-activation portType="polling_Mange_Alert_Events_ptt" operation="receive">
    <activation-spec className="oracle.tip.adapter.db.DBActivationSpec">
      <property name="DescriptorName" value="polling_Mange_Alert_Events.ManageAlertEvents"/>
      <property name="QueryName" value="polling_Mange_Alert_EventsSelect"/>
      <property name="MappingsMetaDataURL" value="polling_Mange_Alert_Events-or-mappings.xml"/>
      <property name="PollingStrategy" value="LogicalDeletePollingStrategy"/>
      <property name="MarkReadColumn" value="TRANSACTION_STATUS"/>
      <property name="MarkReadValue" value="Processing"/>
      <property name="PollingInterval" value="10"/>
      <property name="MaxRaiseSize" value="5"/>
      <property name="MaxTransactionSize" value="5"/>
      <property name="NumberOfThreads" value="1"/>
      <property name="ReturnSingleResultSet" value="false"/>
      <property name="MarkUnreadValue" value="Pending"/>
    </activation-spec>
</endpoint-activation>
</adapter-config>
This poller process is running on clustered environment (2 soa nodes) and it is not working as expected as singleton process.
Please advise to solve this issue ?

Hi,
1.Set Singleton property outside   <binding.jca> like this:
<binding.jca config="polling_Mange_Alert_Events_db.jca"/>
<property name="singleton">true</property>
<property name="jca.retry.count" type="xs:int" many="false" override="may">2147483647</property>
<property name="jca.retry.interval" type="xs:int" many="false"
2.Also you can try setting these values in jca file:
<property name="RowsPerPollingInterval" value="100"/>
<property name="MaxTransactionSize" value="100"/>
3. try to increase the polling interval time.
Regards,
Anshul

TCP Window sizing not working as expected for Windows server 2008 R2 SP1

Hi ,
TCP window size is not working as expected. It is varying . Aplied the hotfix suggested by Microsoft and set the multipliccation factor as 1.The window size is not getting auto tuned based on the client machine. The data transfer rate is getting degraded.
Please help.
Thanks,
Pro1962

Hi,
I think window auto-tuning is enabled.
You can disable it by running the following commend.
netsh interface tcp set global autotuninglevel=disabled
Hope this helps.

Container-Managed Transaction Type Attributes not working as expected

I am having a problem with the container-managed transactions not working as expected. I have 2 methods that work as follows:
MethodA{
for(a lot)
call MethodB;
@Transaction Type = RequiresNew
MethodB{
EntityManager Persist to database
I want the code in MethodB to be committed to the database when methodB returns. The problem is that I am running out of memory and MethodA is failing. When methodA fails after numerous calls to MethodB nothing is persisted to the database.
It is my understanding that when using requires new transactions that a new transaction is started for each call to the method and ends when the method returns while the calling method transaction is suspended.
How am I misunderstanding the requiresNew transaction attribute. What can I do to make a batch insert into my database that will not run out of memory (commit when a methodB returns)?
Thanks in advance.

The problem is that EJB invocation semantics for security, container-managed transactions, etc.
only apply when an invocation is made through an EJB reference. In your case, you are directly
invoking the implementation method from within the bean. The EJB container has no idea that's
happening. It's no different than invoking a utility method.
In order to get the behavior you'd like, you need to retrieve a reference to your own bean and invoke
through that. You can use SessionContext.getBusinessObject() to get the EJB reference for the
business interface through which the method in question is exposed.

Namespaces not working as expected

Hi, I've got problems with namespaces not working as expected. When I isolate a process into a new network and mount namespace, a newly mounted file system will be visible to all processes.
Steps to reproduce:
$ sudo unshare -mn bash
bash# mount -t sysfs sysfs /sys
bash# exit
$ cat /proc/mounts
Result:
/proc/mounts will contain a new line for sysfs. This means the /sys/fs/cgroups directory will appear to be empty as the new sysfs is mounted over the old However you can undo it by
sudo umount /sys
Expected result:
The /sys directory will only be new inside the bash process started using unshare and not anymore once you exit bash.
Did I understand something wrong? Or might this be a bug in the kernel?
Note that when using
unshare -m bash
without isolating the network namespace it will refuse to mount sysfs as it is already mounted or busy. Strange.

Hello, because sysfs is shared, see unshare(1) for more details.
