Ubuntu 12.04 Toshiba satellite L875D keyboard, mouse issues on login

I just bought a new laptop and then tried installing ubuntu 12.04 on it and ran into all sorts of issues from first wireless not working and then keyboard or mouse not working after installing the software updates.

The keyboard and mouse works fine on initial listing of operating systems but when the login prompt comes I cant enter anything on the screen. I was like WTF man.  Googling around gave me an idea of pluggin in an external mouse and usb keyboard and it worked. So I was even more frustrated.  Finally after combining things from various posts I figured out that I have to change grub2 config and add some more settings to it.

Open a terminal and enter

sudo vi /etc/default/grub

and then change the line GRUB_CMDLINE_LINUX="" to GRUB_CMDLINE_LINUX="i8042.nomux=1 i8042.reset"

then run

sudo update-grub

reboot the system and all issues were gone.

    1. Franco I forgot to mention that it was the laptop's native keyboard and mouse that weren't working, I plugged in an external keyboard to make change to the grub file.

Spring query timeout or transaction timeout

If you are using spring to manage transactions then you can specify default transaction timeout using

    <bean id="transactionManager"
        class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource" />
        <property name="defaultTimeout" value="30" /> <!--30 sec--->             
    </bean>

or you can override the timeout in the annotation

    @Transactional(readOnly = false, timeout=30)


or if you are doing it programatic transactions then you can do


DataSourceTransactionManager transactionManager = new DataSourceTransactionManager(dataSource);
transactionManager.setDefaultTimeout(30);

 or you can override the timeout for one particular transaction

TransactionTemplate transactionTemplate = new TransactionTemplate();
transactionTemplate.setTimeout(30);

Python adding pid file

I have a thumbnail generator that launches multiple processes and the correct way to shut it down is to send kill -HUP to the parent process. To automate I had to write a pid file from python, it was a piece of cake
def writePidFile(): pid = str(os.getpid()) f = open('thumbnail_rabbit_consumer.pid', 'w') f.write(pid) f.close()
