Fixed watching flash video in ubuntu 10.10

I had difficulty watching Emmaus video lately, and also video in facebook. It shows only white region and nothing else. Strangely, I can watch youtube as usual. Then I checked my flash whether it’s working. The page from adobe shows I have flash installed. After much searching I suspect that it is because ubuntu use gnash for its flash, and not adobe’s version. I checked I have installed adobe flash, so the next thing I did was to use Adobe’s flash instead of gnash one. To do that, I went to terminal and check the update-alternatives version.

cd /etc/alternatives
ls *flash*

It shows The following files:

firefox-flashplugin
mozilla-flashplugin
xulrunner-flashplugin
xulrunner-addons-flashplugin

So now I run update-alternatives:

sudo update-alternatives --config firefox-flashplugin

And then I chose the adobe version as the default plugin. I did that with the others, but I am not sure whether it is needed. But now it works, I can watch the flash video again
 

Fixing touchpad error (running wild) after upgrade to Ubuntu 10.10

I finally managed to fix my Dell laptop’s touchpad after upgrade to Ubuntu 10.10. The mouse went crazy and start to run all over and open windows here and there. hehehe. After trying several solutions, I got it fixed, by enabling the SHMConfig, following this link.

The step is to edit this file:

sudo vi /etc/hal/fdi/policy/shmconfig.fdi

In my case it turns out it has come content already. which is something like this:

True

All I need to do is to replace the word “True” to “on” following the link above. That seems to solve my problem. If it gets crazy again. I will update this post.

UPDATE: I also disabled the scrolling from “Preferences”->”Mouse”->”Touchpad”, and disabled touchpad when typing. I don’t know whether it affects or not :p

Changing SU password in Ubuntu

My company has a VPN where you simply need to login to a certain URL, it then ask to download an app to start the VPN. However, the program prompt me to enter the “su” password to install it in my laptop. Ubuntu locked the root password, and for daily operational use, we would use “sudo”. However, this program cannot install unless I provided the su password. To reset the su password, I did the following:

  • Open terminal.
  • Type:
  • sudo passwd root

  • And then reset the root password.
  • After that, I installed the vpn program from the web, and after successfully vpn to my company, I disable the root password again by typing:
  • sudo usermod -p '!' root
