Have you done the nutso and “upgraded” or tried out the development release of Ubuntu’s Hardy Heron? I did. I decided to use the command “update-manager -d” to run Gutsy Gibbon’s Update Manager with the flag to update the distribution to the next release. Currently Hardy is at 8.04 alpha 3. For those Debianites, this would be like changing your /etc/apt/sources.list file to point to the “testing” sources and doing the “apt-get dist-upgrade” command after “apt-get update”.
The upgrade went reasonably well with only one temporary show stopper. Java GUI apps stopped working when I upgraded. It seems that there’s a bit of a bug in Sun’s Java 6 that doesn’t agree with the new x.org server (from what I gather). They will fix it in Java 7, which will be a while yet. Thankfully, I found this ubuntu forum post, that helped me solve the problem. I used the sed line:
$ sudo sed -i ’s/XINERAMA/FAKEEXTN/g’ /usr/lib/jvm/java-6-sun-1.6.0.03/jre/lib/i386/xawt/libmawt.so
I hope that this will help you too!
ADDENDUM:
- One thing that you will find is that after every Java update and many X.org updates, your java will stop working again. Adding the “replacement” string “FAKEEXTN” again should fix the behavior.
- As noted by jazz in the comments (Please read the comments on this post), there are different paths for x86 and x64.
- You may or may not require the additional hacks to the /usr/bin/<java application> script to make it work. I didn’t for Azureus or Frostwire.
- Any time someone says to “paste” or write a command with the SUDO command or to do “as root“, think before you copy
- Read the MAN PAGE for SED (and AWK) before using it. Its a powerful command.
Addendum 2: (this is a short one)
Don’t expect anything big with Firefox for this one, at the moment, as Firefox 3 is the designated upgrade from the 2 branch (whether I approve or not - I’m testing and submitting bug reports) ad there seems to be a problem with java and FF3. If you know how to get it working, let me know. There are a few little things about FF3 that are great, but, mostly, I hate FF3. It sucks the biggest moose appendage at the moment. I yearn for the simple days of Phoenix 0.1…
