Sometimes I am a bit over motivated. Thats the reason I upgraded my Ubuntu to 9.10 RC1 yesterday.
Nearly everything worked fine and after 90 minutes downloading and installing Ubuntu 9.10 booted the first time.
The disillusion followed today: What happened with my Eclipse installation?
The LogCat view has no logging type buttons, the Devices view has lost its button for stopping processes and some windows don’t accept a mouse click on their buttons (mostly the OK button). I have to press Enter to get them work.
After a short search I found this bug report for ubuntu: https://bugs.launchpad.net/ubuntu/+source/gtk+2.0/+bug/442078
A workaround is also mentioned there:
Create a launch script for eclipse with the following code:
#!/bin/sh GDK_NATIVE_WINDOWS=1 /path/to/eclipse
I am not sure if Ubuntu is responsible or Eclipse, but after using this launch script, everything worked fine.
