Ubuntu how to right click and scroll

I have not been using my Ubuntu laptop touchpad for ages, but recently i have been traveling and i am taking my laptop out every day, so i have to use the touchpad way more frequently.

A wrench got thrown in my thinking process when i saw i cannot right click or edge scroll but it looks like this behavior was just changed. If it’s simpler or not it’s for you to judge:

Right clicking in Ubuntu is now achieved by using 2 fingers to click on the touchpad.

Edge scroll seem to not be working anymore, however you can scroll by using 2 fingers instead of one, anywhere on the touchpad.

Happy Ubuntu-ing!

Shared object “libstdc++.so.6” not found, required by “arcconf”

The error below, happens usually on FreeBSD10:

Shared object “libstdc++.so.6” not found, required by “arcconf”

The problem with this, is that the binaries are compiled by Adaptec. The solution is pretty easy tho:

cd /usr/ports/misc/compat9x && make install distclean 

Done, your arcconf utility is now working.

cups-client-1.7.2 conflicts with cups-image-1.5.4_1 (installs files into the same place)

If you are getting the error below while trying to upgrade ports:

cups-client-1.7.2 conflicts with cups-image-1.5.4_1 (installs files into the same place)

This happens because of the cups-image dependencies have been changed. The fix is pretty easy:

pkg delete -f cups-image\*

Now you can upgrade the cups-client and ghostscript ports without issues.


freebsd mounting from failed with error 19

So yesterday i got a new server with an Adaptec 6405e card inside.

When trying to load FreeBSD 9.1, the install script would not see the raid10 array that i created.

I went about this by booting from the install disk, via ipmi, and then on the install screen, went to the shell prompt. I enabled the network card and gateway, and i downloaded the drivers for the 6405 card from the Adaptec website. Then i uploaded the drivers to one of my servers, and used ftp to download them into /tmp, and load the FreeBSD9 driver via kldload :

kldload /tmp/freebsd9/driver/aacu64.ko

Now, the raid array is fully recognized, and i installed the FreeBSD 9.1 business as usual.

Upon booting up, i forgot that i loaded the drivers only on the live cd, but not on the actual OS itself, so i got freebsd mounting from failed with error 19. This means that the system doesn’t have the drivers for the raid array, and doesn’t recognize the filesystem.

I am just booting now from the live cd once more, i will be reloading the drivers, mount the installed OS, and download and unpack the drivers there. Afterwards i will be rebooting, and at the boot prompt i will manually load the drivers, boot the system, and add the drivers to the OS, and be good to go. At least that’s the plan. Will update later with progress.

nagios not sending mail

I just checked my nagios logs, and i found that my email notifications were not working.

[1250176586] SERVICE NOTIFICATION: nagiosadmin;sql01;/dev/sdb1 Free Space;OK;notify-service-by-email;DISK OK – free space: /var/lib/mysql 478954 MB (89% inode=99%):

Easy fix for this one also:

yum -y install mailx
