I have just installed Ubuntu 11.10 on my PC and when I saw that the Software Center has Arduino 0022 now, I was hoping that it would be as easy to install as on Windows.
Unfortunately, this was not the case. I installed from the Software Center and when I connected the Arduino,it was flashing the Pin 13 LED and the TX LED was on constantly. The IDE was very slow and when I clicked on “Tools” to set the serial port, it took several seconds until something happened! Then I found only the port “tty0”, while when I followed the “Complete Numpties Guide to Arduino on Ubuntu” I could see with dmesg that the Uno was recognized as ttyACM0.
I uninstalled the IDE and went according to this blog post: http://mattgreensmith.wordpress.com/2011/11/24/installing-arduino-0023-on-ubuntu-11-10-oneiric-ocelot/ . Still no success. I then tried what is given in the Arduino Playground:
if you use the USB port to dialog, you should add yourself to the group ‘dialout’ in order to have write permissions on that port: sudo usermod -aG dialout
That also didn’t work. What can I do now?
