Ubuntu 9.04 – KDE Cpu usage

Sunday, May 10th, 2009

Not sure why, but suddenly KDE4 has gone berserk on my ubuntu 9.04 machine.
Before I restart the machine, here is a screen capture of the CPU usage – 50% means one of my CPU is working 100% for KDE.

Ubuntu Jaunty and Android ADB

Wednesday, April 29th, 2009

I have recently upgraded my ubuntu machine to Jaunty. When I tried to work with my G1 Devphone, I found out that adb doesn’t seem to find the device.

Luckily, I am not the first one to find it, and could find a solution in an Android Group :

cp /etc/udev/rules.d/50-android.rules /etc/udev/rules.d/51-android.rules

/etc/init.d/udev reload

Just don’t forget to disconnect and plug-in the device again, and there you go.

MySQL Workbench on ubuntu AMD64

Wednesday, January 28th, 2009

MySQL workbench will help you design your MySQL Database.

The only problem is, binaries are not available for Linux amd64 machines. (Again, I kick myself for choosing amd64).
So, what a normal Linux guy does? – Obviously, download the source code, compile and try to run. I have done just that, created a debian package (after making sure all lib dependencies are met).

But, the workbench does not start. I get a very nice splash screen, but that’s it:

I must admit, after some more fiddling, trying, guessing, I started a Windows vitual machine (over Virtualbox) downloaded the windows installation, and it works perfectly.

Running Eclipse 3.4 on Ubuntu 8.10 AMD64

Monday, December 29th, 2008

Everyone rants that Ubuntu didn’t upgrade Eclipse in a long time. Still Release 3.2 is deployed, which is quite ancient in Today’s terms. I have also struggled with this issue for a while, till I found an answer (sorry, didn’t bookmark the source).

  1. Download the Linux 64 version from Ecplise.org – That’s quite obvious
  2. Check which Java application is the default- follow from /usr/bin/java to the /usr/lib/jvm directory
  3. From a terminal, in the eclipse directory perform the following:

export JAVA_HOME=’desired /usr/lib/jvm/’ directory’

./eclipse

Lexmark x610 on Ubuntu

Monday, December 15th, 2008

As it turns out, I cannot fully migrate to Ubuntu as my printer is not supported.

I guess I’d have to install the drivers on a Virtual machine running windows or buy a new printer…

I find it quite annoying that after so many years of Linux deployments, including the new EEE PCs and the likes, Lexmark didn’t find the time to implement a driver.

Hey, Lexmark, if you want I can do it for you, just provide the information (and some money).

Picasa on Ubuntu

Friday, December 12th, 2008

One of the best application created (actually purchased) by Google is Picasa, and there is a version for Linux. Downloaded and installed (the AMD64 version). Runs perfectly. 

The only annoying part was that it runs over Wine. Google, PLEASE, port your application to Linux, don’t just use Wine! 

Let’s not forget that Chrome does not have a Linux version.

Ubuntu – mission accomplished

Thursday, December 11th, 2008

I feel a bit humbled after I have ranted in my previous post. 

After I fixed all my HW installation issues, including a faulty CDROM, the installation ran perfectly INCLUDING the Ethernet driver. 

It is working perefectly, and now I can start my development

Ubuntu issues – Intel Core 2 Duo E7200 with Asus P5KPL-CM

Wednesday, December 10th, 2008

Bought myself a new computer, decided to be really “smart” and assemble one myself. 

I got: 
1) Asus P5KPL-CM
2) Intel Core 2 Duo E7200
3) 2GB memory – reasonable quality
4) Very bad case
5) Awful power supply

Too many problems for such a few components:

  •  The Heat Sink (CPU fan) did not install easily, had to force it for a long time. I have actually though I did, till I noticed a heat alarm during the boot… retried, and retried till it worked. 
  • Now, the heat sink cannot be installed when the motherboard is screwed to the case… since it need more height. Put in some brackets (did not have enough)… so it is not that stable
  • Ran and ubuntu live CD and noticed I don’t have ethernet – seems there is a solution – need to compile and install the drivers :)  
  • Getting errors during the boot before installation:  Buffer I/O error on device FD0, Logical Block 0 . It seems I am not the only one .
  • KVM does not seem to work – I am getting a keyboard error. Went to KSP and they claimed it is working- STRANGE. 
Getting too late. Will continue tomorrow. 
THIS IS WHY LINUX IS NOT READY FOR THE MASS MARKET! 
I can handle this, and in a wierd way, enjoy it, but not sure how many people out there can do the same.
