Why is my laptop so freaking hot?
Posted by evan in Uncategorized on August 26, 2010
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.
Notice the temperatures at the top. The first two are Core0 and Core1, the other 2 are other sensors. The CPU is running at 1.0 GHz due to SpeedStep and the temp is still 70°C.
Edit: I forgot I’ve been logging temperature via sensord. I just turned the computer on after having it off all night and within 10 minutes the CPU is back up to > 60°C.

Ripping a DVD on Fedora Core 13
Posted by evan in Uncategorized on July 2, 2010
I thought this would be a pretty straightforward task. It was, though it took several minutes to track down the CSS library needed for decryption of the DVD. All I want to do is copy Talking Words Factory to my phone so my kid can watch it in the car if needed. It looked like Brasero was the tool for the job, but I got some error about needing a plugin for it to be able to decrypt it. I found libdvdcss here and after installing the RPM, everything worked. Now I just need to encode it with ffmpeg.
Flash plugin on Firefox on Fedora 12 x86_64
Posted by evan in Uncategorized on June 9, 2010
I know I’ve been through this before because I’ve setup Fedora before and it’s working. But I just installed FC12 on my desktop at home (since my Seagate drive bricked itself a few days ago and I had to reinstall anyway) and while I finally got the Adobe Flash plugin working, it didn’t have any audio, which made YouTube kind of suck. Anyway, this of course was a solved problem, I just forgot where the fix was located… but duh, it’s on the Fedora website. A simple
yum install flash-plugin nspluginwrapper.x86_64 \
nspluginwrapper.i686 alsa-plugins-pulseaudio.i686 \
libcurl.i686'
and everything appears to be fine. Thank you Fedora!
Upgraded to Fedora Core 12
Posted by evan in Uncategorized on April 20, 2010
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!
The other problem I had was reinstalling VMware Workstation – I couldn’t. I got this error: /tmp/vmware-root/modules/vmnet-only/vnetUserListener.c:240: error: ‘TASK_INTERRUPTIBLE’ … etc. I ended up having to edit the vmplayer source files directly (!!!) to get them to compile – instructions found here
So far FC12 seems exactly like FC11. But that’s fine – I only upgraded because I didn’t want to be on a dead-end version once FC13 is released.
Everything works on my laptop except Bluetooth
Posted by evan in Uncategorized on November 6, 2009
This is pretty weird. Bluetooth worked fine under Win XP. The computer is an HP/Compaq nc8430. When I go to the Bluetooth control panel I get “Your computer does not have any Bluetooth adapters plugged in.” The weird thing is, sometimes I’ll see the bluetooth logo in the taskbar at the top, but then when I look again it’s gone and I have no idea how to get it back. When I booted it up this morning I noticed the icon was there so I ran some of the debugging tools for Bluetooth and checked dmesg and this time at least it looks like at least there’s proof that Linux CAN see the Bluetooth adapter, I just don’t get why it then stops recognizing it after just a minute or two, and a reboot doesn’t even consistently bring it back.
NILFS – A File system to make SSDs scream… in pain?
Posted by evan in Uncategorized on October 27, 2009
So I got this 128 gig Corsair SSD and put it in my laptop at work. After some fiddling I copied my old disk over to my new disk by booting to Knoppix and doing dd if=/dev/sda of=/dev/sdb bs=4k conv=notrunc,noerror. It’s a lot faster, but what’s really fast now is my Windows XP VM. Anyway, I was looking into other filesystems to try out on SSD to improve speed and I found this article claiming that NILFS is the best choice. So I decided to test it using the same ghetto test I always use for filesystem performance: dd!
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)
Posted by evan in Uncategorized on October 21, 2009
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).
That’s all it takes to get the Sun Java plugin working in Firefox on Linux.
I put Fedora Core 11 on my work laptop
Posted by evan in Uncategorized on October 21, 2009
My work laptop, which I got around the end of 2006, was starting to run like crap. Pretty sure it started around the time I put antivirus on it, which reinforces my theory that antivirus is a virus itself. Anyway, being bored with Windows XP and having already played with Windows 7 at home, I decided to install Linux. The last time I tried Linux desktop was around RedHat 7.3, which was a long time ago… pre-Fedora even. I’m pretty happy with CentOS on the server side and was set to try CentOS 5.3 on my laptop when someone suggested I go with FC due to more bleeding-edge driver support. Even though the hardware is pretty old at this point I figured it was worth a shot.
Generally everything works pretty well. Everything pretty much works out of the box – I had dual screens up at native resolution, it even recognized my phone as a camera when I plugged it in to charge it. Best of all, I was able to resize the NTFS partition (rather than blowing it away) so I can still boot back to XP when the need arises.
There are 2 problems I’ve had so far though:
- the computer now hovers between 76 and 85 degrees Celsius, whereas under Win XP it generally peaked around 68 C. I tried underclocking the CPU down to 250 MHz but the problem persisted.
- The Java plugin for Firefox … wtf? How can this not work? I downloaded Sun’s JDK and symlinked the libjavaplugin_whatever into /usr/lib64/mozilla/whatever/ and that didn’t work. Then I tried “yum install java-plugin” or something like that and that installed some OpenJava-ish plugin which looked like it was going to work, but when I logged into the Raritan KVM and clicked “Connect” it wouldn’t work. I booted up Win XP in a VM and Firefox with Java works fine. Really annoying and dumb.
I’ll probably try Ubuntu tomorrow as several people suggested it runs cooler than Fedora. If that fails then I guess I’ll go to Win7 after all. I also want an SSD for my work laptop now… my Windows VM seems to spent eternity spinning my crappy 5400 rpm drive. Plox.
