VT1708/A workaround for Ubuntu 10.10

I got this old mainboard (ASUS M2V-MX SE) which I need to install a newer version of Ubuntu (10.10 in this case) from previously 8.04.  Decided to have a clean install and found that there’s a current bug in kernel regarding the VIA VT1708/A audio card. Here’s what I’ve found in the net

https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/664785

After few minutes of searching for possible solution, finally I’ve  found one that works:

https://bugzilla.kernel.org/show_bug.cgi?id=16921#c5

Here’s how:

1. Modify your grub default boot options

$> sudo vi /etc/default/grub

2. Add “pci=use_crs” on your current grub option, which looks like this:

GRUB_CMDLINE_LINUX_DEFAULT=”quiet splash pci=use_crs”

3. Then update your grub.

$> sudo update-grub

4. Reboot and done.

LibreOffice / OpenOffice Base Slow

Made my initial setup for a basic database using LibreOffice Base, on my old workstation with OpenOffice 2.4 it works fast, then brought it home to continue the design, using my better specs laptop with LibreOffice 3.3.1. Tried to run it if it works fine, to find out the form open very slow and even navigating records.

Tried to remove LibreOffice and restore the normal OpenOffice 3.2 package from Ubuntu 10.10, still got the same problem. Then tried to add up some memory for the graphic cache in the OpenOffice option. (Tools -> Options –> LibreOffice/OpenOffice.org -> Memory). Hoping everything will work fine then but still a failure.

Lastly I tried to change the java settings, tried it on both openjdk-6-jre and sun-java6-jre (1.6.24), still not working in good performance. Nearly giving up, lastly I tried to use lower version of java runtime.

Here’s how:

1. Download the java-sun-jre-1.6.21 from http://java.sun.com/products/archive/j2se/6u21/index.html

2. Move the file to your $HOME/bin and make it executable

$> mv jre-6u21-linux-i586.bin
$> chmod a+x jre-6u21-linux-i586.bin
$> ./jre-6u21-linux-i586.bin

4. After extracting the files, configure your LibreOffice/OpenOffice.org to use the older java runtime (Tools -> Options –> LibreOffice/OpenOffice.org –> Java). Add the path from where the extracted files currently located.

5. Restart your LibreOffice/OpenOffice.org and verify if your database now runs smoothly.

6. Done.
