Ubuntu Studio JDK & Browser Plugin Installation Notes

After way too much futzing, my system is back. Short story: replacing a stick of memory and installing Ubuntu Studio 7.04 (rather than 7.10) did the trick. I suspect something in xorg.conf (probably the depth setting) was messing things up. The next time I upgrade, I’ll save the working version of this file first.

While I’m rebuilding, I thought I’d capture my steps for installing Sun’s JDK and configuring the plugin with Firefox.

  1. Go to http://java.sun.com/javase/downloads/?intcmp=1281 and download jdk-6u4-linux-i586.bin
  2. Assuming the download went to your desktop, open a terminal and enter the following:
    sudo bsh
    cd /home/your-id/Desktop
    mv jdk-6u4-linux-i586.bin /opt
    cd /opt
    chmod +x jdk-6u4-linux-i586.bin
    ./jdk-6u4-linux-i586.binHold the enter key down until the yes/no line appears. Type “yes”, hit enter and wait for the installation to complete.
  3. Continue by entering the following commands:
    rm *.bin(This next one is all one line)
    ln -s /opt/jdk1.6.0_04/jre/plugin/i386/ns7/libjavaplugin_oji.so /usr/lib/firefox/plugins/libjavaplugin_oji.so
    cd /usr/local/bin
    ln -sf /opt/jdk1.6.0_04/bin/*
    exit
  4. Close all Firefox windows. Restart Firefox.
  5. To test the plugin, goto http://java.com/en/download/installed.jsp?detect=jre&try=1 and click “Verify Installation” At this point you should see: Congratulations! You have the recommended Java installed (1.6.0_04)
  6. To test java, open a terminal and enter:
    java -jar /opt/jdk1.6.0_04/demo/jfc/SwingSet2/SwingSet2.jar

Chain of Despair (Again)

I thinking of throwing in the towel.

Now, with the holidays are over, I was just about to get some time to exercise my creative side using the Ubuntu Studio installation which had been working really well for me. That is not going to happen. The sad tail goes something like:

  • I wanted to copy an audio CD.
  • serpentine didn’t work
  • I tried to update
  • update failed
  • I tried to fix the update problems but, after a day, i gave up, and just downloaded Ubuntu Studio 7.10
  • after installing the newer Ubuntu Studio. I get these single pixel dots all over anypart of the screen that has motion in it. The dots are mostly cyan and magenta but, there might be other colors. Who cares? Note that the login page looks fine. I’m thinking, hoping this problem could be solved by fiddling with xorg.conf
  • firefox wouldn’t run – it just dumped core. So I updated it.
  • Firefox was working again but, gnome preferences could not be set – keep seeing some error about bonobo.
  • tried fiddling with xorg.conf – fewer dots but, they are still there
  • probably other issues I can’t remember right now ’cause I’m running a Knoppix off a live CD to post this.
  • Oh here’s one: the “check CD for errors” failed for the Ubuntu Studio disk!
  • with knoppix I’m seeing the dots too!
  • What the freak happened?
  • On one of the reboots this morning, I ran memtest It failed.
  • diddled with BIOS settings, ran memtest again…failed!
  • Take a break and realize that the recent cold weather, low indoor humidity, and my Crocs conspired to wreak ESD havoc on the RAM in this system.
  • Days and weeks past
  • replaced a stick of memory
  • memtest passes
  • more days pass – let memtest run for days.
  • get excited about being back on track
  • Download Ubuntu Studio again, thinking that last one was possibliy bad. burn a new disk.
  • again the “check CD for errors” fails
  • Install any way and the dots are still there! I’m sure it nothing to do strictly w/Ubuntu ’cause my good old Knoppix live CD Shows very similar dots. linux random dots
  • Here what they look like if you scroll – they kinda turn in to vertical lineslinux random dots turn in to vertical lines

I really need help. This same video hardware was working fine before with 7.04. I suppose I could just try reinstalling that and see what happens.
