I installed the current IDE on my EEE PC running easypeasy ubuntu and while the IDE works and interfaces with my new Arduino UNO, there is the number "1" flashing on and off on the bottom of the IDE window. It's maddening since this causes the dialogue box on the bottom to jump up and down and ultimately the whole IDE slow down. Anyone seen this before. Any suggestions for a fix?
The value is the cursor's line number.
The only suggestion I have (and it is a weak suggestion) for fixing the problem is to ensure the Java run-time is up-to-date.
Good to know what it is. I'll try removing the openjdk and installing the SUN versions. After your post I finally found this reply on the old forum which shows that I'm not the only person to ever experience this flickering. The original poster noted that removing openjdk completely did not solve the problem. I'm hoping to reach out to him/her to see if s/he found a solution!

If you have a standard Ubuntu 10.4 installation you will get openjdk-6-jre installed by default, but arduino-0021 doesn't work with openjdk-6-jre, it needs sun-java6-jre.
Removing openjdk-6-jre by Synaptic packet manager may not remove the openjdk-6-jre configuration files.
It is important to have openjdk-6-jre completely de-installed, which means also the configuration files, otherwise the arduino program may not work.
Check the installation of sun-java and openjdk:
dpkg -l | grep -i java
…
rc openjdk-6-jre
rc openjdk-6-jre-headless
…
ii sun-java6-bin
ii sun-java6-fonts
ii sun-java6-jre
ii sun-java6-plugin
If you find openjdk-6-jre* entries like above you have to remove the configuration files too, try:
sudo dpkg -P openjdk-6-jre openjdk-6-jre-headless
After I did this I got the Arduino IDE starting up without flickering.

I have to revise my last post regarding the flickering, this is not solved with removing openjdk configuration Sad
Good or bad, please report back with the results.
Gave it a try but it didn't work. Removed openjdk and all config files. Installed sun-java6-jre. No go. Window still jumps up and down with number "1" flashing. Been at this 4 nights... driving me a bit nuts 
Hopefully someone with Linux (especially Ubuntu) will offer suggestions.
Man, I tried just about everything but no go so... the real solution was a bit drastic but worked perfectly. I dumped easypeasy (which was getting to big for the available memory on my eee pc 702 anyway and installed Peppermint Ice. From there, followed the normal directions "Complete Numpties Guide to Arduino on Ubuntu" http://www.pluggy.me.uk/arduino-ubuntu/ and it's up and running with no screen jiggles. Few points... the screen is too narrow and tall for the oddly shaped screen on the 701 but if you hit F11 the IDE does a great job of jumping to the rust the right screen size. Also, I couldn't "choose" the USB port but after connecting the Arduino the OS (or IDE) helped by providing a dialogue indicating that the serial port couldn't found but looky here I found this one... want to use it? Selected the only choice and Voila I'm in business. So far Peppermint Ice also looks quite sweet
Thank you for the follow-up. I'm glad you got it working.
