I installed Cinnamon on my Ubuntu 12.04, and it works well, but sometimes it just freezes for no reason. I can move my mouse but can't click on anything.

So I want to restart Cinnamon from tty, like I used to do with gnome shell. How do I do that?

I tried killall cinnamon and nothing happened.

Then I tried export DISPLAY=:0.0 , cinnamon --replace and still nothing.

I guess the command cinnamon is not valid. I don't want to restart the whole X server because then all of my windows will get closed. I just want to restart the window manager cause I believe it is causing the problem.

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!

When my computer goes to console mode (booting up, shutting down or Ctrl + Alt + F1)), the text is super big. I can't take a screenshot of it, but it looks like a 640 x 480 resolution. My monitor normally works at 1440 x 900.

I remember that the console text that appeared while installing from the CD was nice and small.

How can I make the console text look like it looked while booting from the CD?
