Usually I am careful when it comes to upgrading. I had my share of Gentoo updates which caused severe problems when updating files it should not replace. So I usually wait some weeks until new releases are sufficiently tested by enough people as I rarely do I need features right way. The last Kubuntu upgrades though went pretty smooth. No big issues, and only cosmetic ones. So I dared to upgrade on the day after Ubuntu/Kubuntu were released. And hey, no big issues!
On my Dell 3700 everything continued to work. I had to remove my home directory’s .kde and some other directories, and Flash on Firefox was awfully quiet. And that was it already. Dual screen worked fine after re-configuring (I actually put back the old xorg.conf). Network was ok from the start.
After testing and finding the low volume in Flash very annoying, I tried a fresh re-install. But I could have saved those 2h: no difference. which means the upgrade worked just fine.
Some small issues though, but not a fault of Kubuntu:
- Eclipse is upgraded to 4.0 (Galileo). The AVR Eclipse plugin is not yet updated to handle this though, so I cannot install it.
- Flash audio is quiet. In Firefox and Chrome.
