Maverik's questions

I have an Ubuntu 11.10 system with 2 users:

• The first was created during the installation
• The second instead was created after. It belongs to the sudoers group.

Now the problem is that when the second tries to use a device ttyUSB0 the following error is returned:

"Could not open serial port /dev/ttyUSB0"

I was able to fix it by using:

sudo chown :second_user /dev/ttyUSB0

However when I disconnect the device and reconnect it the problem comes back.

Is there a way to allow different users to access the devices? I suppose I have to add the user to a specific group. Currently the owner is root and the group is dialout. However I'm not sure about the group and I don't know how to add the user.

Thanks!

I'm trying to make a screencast in Ubuntu 11.10. I need to insert some text for explaining all the steps. Something like this.

I looked for older questions and I saw that one of the few software that allows you to insert some text in the screencast is wink.

However it doesn't work for me on Ubuntu 11.10. When I try to start the screen cast all the wink Icon disappear from the sidebar and so I'm not able anymore to stop the registration.

Is there a way for fixing it? Otherwise, is there an alternative software?

Thanks!
