Known Issues

• There are reports of the open source ATI drivers being very slow. Be sure to not have Virtual size set to high and try with XAA instead of EXA; fixes it in some cases.
• Nvidia 64 computer chipsets still cannot boot kernel without pci=nomsi option
• Qt shows repaint bugs with some but not all Intel Gfx Chips. Using XXA or UXA fixes them in some cases, but hurts performance, please report UXA on this thread. Bug 338669.
• Qt repaint bugs also seen in some situations using the open source ati driver; XAA fixes this in some cases. Bug 350120
• Connection to non-broadcasting (hidden SSID) wireless networks with the network-manager widget isn’t possible Bug 330811
• Network Manager does not connect to some networks Bug 339313
• Network Manager is not added to the panel on upgrades Bug 349066
• KPackageKit (which is now the default package manager for Kubuntu Jaunty) doesn’t support installations which require a removal or updates which require additional software. The packages to be removed / installed will be shown as blocked. Bug 342671
• Kmail sieve functionality is buggy and causes CPU hang. You shouldn’t use it at the moment.

More issues are listed on the Ubuntu Release Notes.

Kubuntu Ports

Kubuntu 9.04 is now available for the lpia, and powerpc architectures, including the Sony PLAYSTATION 3. For those unfamilar with ports, the powerpc port is designed for Apple Macintosh G3, G4, and G5 computers, including iBooks and PowerBooks as well as IBM OpenPower machines while lpia is designed for devices using the Low-Power Intel Architecture, including the A1xx and Atom processors.

Live images are available for powerpc, and alternate images are available for powerpc, powerpc+ps3, and lpia.

Please note the SPARC, IA-64, and HPPA images are known to be broken, and are completely unsupported. We hope to add support for these architectures in future Kubuntu releases, if your interested in assisting, please contact Michael Casadevall (NCommander) in #kubuntu-devel on irc.ubuntu.com

The installation manual for powerpc: power pc installation
The i386 installation manual applies for lpia: lpia installation

These images are available at: Kubuntu ports images

In addition to the normal Kubuntu channels, three additional channels are available for port users support:
#ubuntu-ports – For general ports discussion and support
#ubuntu-powerpc – For {X|K}ubuntu powerpc discussion and support
#ubuntu-ps3 – For Playstation 3 discussion and support

Known Ports Issues

• On some PowerBooks with NVIDIA cards, usplash does not display while starting from CD. It remains at a blank screen for 1-2 minutes then starts up. Everything works, it simply takes time to startup
• On some PowerBooks with NVIDIA cards, usplash colors appear inverted. This is comestic and harmless.
• PlayStation 3 requires the alternate PS3 image to successfully install.
  – Please note that the PS3 barely meets the minimal requirements for Kubuntu
• On all port architectures, including lpia, there is no linux-restricted-modules package which means hardware that requires closed source blobs are non-functional.

Ports Support

All non-i386/amd64 ports of Kubuntu are community supported, and are not eligible for support from Canonical. Please note that while these architectures are community supported, normal updates available via jaunty-updates and jaunty-security are generally available. Backports and jaunty-proposed are also available.
