Java for PPC

Anyone out there with an older Fedora/Fedora-based distro (or RHEL-based, in fact) looking for an up-to-date Java Runtime or JDK? I thought, up until this point, that the only answer was the OpenJDK (Sun doesn't supply JREs or JDKs for the PPC anymore).

Of course, then last week, a Java developer told me about how IBM makes and maintains a JDK specifically for the Linux/PPC platform. I went and downloaded it, and it works fine on both my Fedora 9 and my Yellow Dog 5.0.2 (Fedora-Core 5.0) installs.

Fans running at full speed all the time on G4 laptops

You can disable the module therm* in /etc/modules. People have reported the following:

Got it. It is working now. I disabled the Therm* module, and the fans returned to their normal behavior! That is, they no longer run full tilt all the dammed time, and instead come on only as needed, as the systems' temp rises.

Solution was found here.

Shutdown & Reboot Freeze after Karmic Upgrade

I have an old powerpc iBook G4. Upgraded to Karmic today and all is well aside from the shutdown and reboot freeze. This appears to be a widespread problem for both pc and ppc users from searching for a solution today.

Last messages on the screen are:
init: usplash post-start process (1944) terminated with status 1
* Shutting down ALSA...
* Asking all remaining processes to terminate...

tweaked xorg.conf for emac with compiz!

After much experientation, digging around the internet and sifting through mountains of forum posts both here and elsewhere, I have found the magic line that will allow my eMac to use the default xserver with default ati driver using the internal display under intrepid. Under the "Device" section for your video card, you need to add the option "monitor-DVI-0" and point it to the name you gave for the monitor. My revised /etc/X11/xorg.conf file:

CPU Frequency-scaling for openSUSE 11.1 fix!

Bummer - the standard cpufreq just leaves my G5 iMac running at full speed at 1.8ghz, and no amount of cpufreq-util commands would make it actually scale. I could change it from performance down to powersave, but any attempt to use ondemand or even conservative would fail - due to the apple hardware taking too long of a transition, so it would default back to performance.

To make matters worse, there are no cpudyn or powernowd packages in openSuse afaik.

So, I just compiled and installed cpudyn, one of my favorites for ppc cpu frequency scaling.
