Shrinking partitions, installing/upgrading to FC15, and systemd/chkconfig.

Why is my laptop so freaking hot?

Thu, 26 Aug 2010 14:07:07 +0000

HP Compaq nc8430, Core 2 Duo T7200 2.0GHz. Fedora Core 12 x86_64, kernel 2.6.32.19-163.fc12.x86_64 (just updated via yum).

At idle, with nothing running in the foreground, the CPU is around 70-72° Celsius, and the other sensors are 80°+. Why is this? It seems like every time I run yum update the machine gets hotter. I wonder if there’s any way to figure out what’s causing this. In any case, it’s pretty annoying. It’s uncomfortable putting the thing on my lap for any length of time.

Upgraded to Fedora Core 12

Tue, 20 Apr 2010 17:24:14 +0000

I upgraded my work laptop from FC11 to FC12 yesterday using the “preupgrade” tool. It was pretty simple, though it took a lot longer than I expected. There was some funkiness with my screen going crazy after the upgrade - my external monitor and the laptop’s LCD both did this crazy wavy-line thing. I tried changing the refresh rate, running system-config-display, nothing worked. I found a post that suggested passing “nomodeset” to the kernel boot options - that solved it. Yay!

How to install the 64-bit Sun Java plugin on 64-bit firefox on 64-bit Fedora Core 11 Linux (which happens to use 64 bits)

I’m giddy! I found this post on mozdev.org which was magical.

[evan@ehoffman ~]$ java -version
java version "1.6.0_17"
Java(TM) SE Runtime Environment (build 1.6.0_17-b04)
Java HotSpot(TM) 64-Bit Server VM (build 14.3-b01, mixed mode)

[root@ehoffman plugins]# uname -a
Linux ehoffman 2.6.30.8-64.fc11.x86_64 #1 SMP Fri Sep 25 04:43:32 EDT 2009 x86_64 x86_64 x86_64 GNU/Linux
[root@ehoffman plugins]# pwd
/usr/lib64/mozilla/plugins
[root@ehoffman plugins]# ln -s /usr/java/jdk1.6.0_16/jre/lib/amd64/libnpjp2.so

The main thing I was missing was that the plugin isn’t libpluginjava_oji.so, or whatever I thought it was, but libnpjp2.so. Once I created the symlink into /usr/lib64/mozilla/plugins it worked (as verified on http://www.java.com/en/download/help/testvm.xml and http://www.java.com/en/download/installed.jsp).
