Mouse Pointer Madness

Due to a "thermal issue*" I had to upgrade my core Linux box today. I ended up with an AMD3000 and nForce2 motherboard from Maplin as that was the current bundle on sale.
Linux did a magnificent job of just getting on with the new hardware on the reboot (in contrast to the XP partition which ended up in a re-install), the only issue was that once the new nvidia drivers had launched the mouse developed a personality all of its own. Whilst under my control for much of the time, it would occasionally have a moment where it decided to go and do its own thing. Random clicks and a preference for either the top right or bottom left of the screen can really spoil your day.

It turns out that this little gem is a combination of running a KVM switch (mine is a Belkin) and a faster processor. Adding the kernel boot param of

psmouse.proto=imps

on the end of the kernel line in /boot/grub/grub.conf is the solution.

*"thermal issue" - defn - allowing an internal cable to foul the processor fan overnight, don't try it bad things happen!

Fedora Core 2 - Oracle Upgrade Fun

After waiting for a while, I finally upgraded my Fedora Core 1 box to Core 2. In general fairly painless and I've noticed some general increases in performance - the GUI is snappier and my Java applications are benchmarking 10-18% quicker.

My only real problem was that my original 9i instance will not start up under Core 2 whatever I do. I jumped through every hoop I could find on google for looking at how to deal with the dreaded shared memory issues, but nothing worked for me.

In the end I gave up and installed 10g instead, the normal install issues apply like -IGNORESYSPREREQS to get around the distribution name. The install worked for me aside from the default database generation, this trick fixed that issue for me eventually.

It also imported my dumps from 9i seamlessly and the new enterprise manager web console is very cute.
