Now that Wiley has been released, development for Ubuntu 16.04 (Xenial Xerus) has begun. Daily images have already been posted. Both Lubuntu and Ubuntu-MATE have PowerPC images ready for testing. People over at the UbuntuForums have alreasdy begun testing the new images. Also there was hope that the radeon r300 bug was fixed if you looked at the Mesa 11.0.3 release notes. Xenial as of now comes with the Mesa 11.0.4 package. So here are my initial thoughts.
The install was pretty standard. There was nothing that stood out and to be honest this is a good thing. The installer should ask you the questions the app needs to build the system according to what you have requested. I noticed in Wiley that section the manages setting the timezone was broken and you needed to set the timezone after install. This has now been fixed.
The desktop had a realy nice default look to it. I made the panel dark using the Lubuntu-Dark theme. The panel apps I tried worked as well. I noticed in 14.04 that the weather panel app did not work. Now in 16.04 it is working. The system resource monitor worked as well. I like seeing the CPU and RAM usage plus the app launches lxtask when you click on it. A lot of the default apps that normall come with Lubuntu were not installed but this is something I expected since it is so early in development and there maybe changes as to what ships in the final release.
Sadly eventhough Mesa has stated this bug to resolved it is not the case. You cannot get 3D acceleration with radeon r300 driver with a default depth of 24. Graphics rendering has been an issue for PowerPC since moving to KMS. It is not a show stopper in using Linux on PowerPC, but it is annoying.
Browsing the Web
Firefox worked as expected. I install Midori, Qupzilla, Luakit, and Surf as well. Midori works great! It looks like even downloading files is working better. In the past there were times when that feature would crash. It is really good to see improvement there. Also uploading files is working as well. Luakit has gotten a little buggy. There were times when the browser crashed when I used it. It is something I have seen in 15.10 and I know there is an open bug report on it. Qupzilla has issues when trying to scroll down using the touch pad. Other than that it ran pretty well. Running Surf showed no issues that i could see.
My first impression of Lubuntu 16.04 are pretty optimistic. I will be checking in on it when the Alpha and Beta releases come to see how the distro is doing under PowerPC.
