I had installed Yoper 3.0 on my PC, without additional software installation option. After installation, I try to add CDROM as channel through smart GUI tool. While selecting CDROM/DVD option in channel selection dialog, it was showing “no local media found!” message. It was applicable for command line smart also. Note: I checked the media, it was perfect with checksum. I attempted the CD with both CD Driver and DVD Combo drive. No use.

To my surprise, “system:/media/hdb” on location bar on konqueror was showing the content of installation media CD. But there was no such directory (/mnt/hdb) available. I confirmed the same with shell. Then I created /media/hdb manually and mounted the CD. that is it! all problems solved. I have installed ykde-standard from CD. Thanks a lot for the wonderful support from Musikolo in Yoper forum!

Today’s The Hindu report on IT Trends talks about 3D Printing. You can make 3D plastic objects at home as per your design. This printer makes you to capture the existing object like cell phone casing, boxes, plastic casing for fragile materials which are more common in households. Though this technology is used in Industry for prototyping, it has become available to lay man also with the cost around $5000 from http://www.desktopfactory.com/ .

Dr. Adrian Bowyer who is behind this technology has promised to release the technology under GNU license. That’s great! This price tag will come down to $400 since other manufacturers too start manufacturing the 3d Printer based on open sourced technology.

I keep upgrading my Home PC with better peripherals to make it to breathe better for long time. The recent one is a nVidia Graphics card of model 6200A – 256MB – 8X from Zebronics. I got it from ebay for Rs.2000 ($47) which is 7 months old. Now my PC configuration is

Intel PIII/850MHz, Intel 82815 Chipset, PC133 450MB, nVidia 6200A 256MB, 20+10 GB HDD

I have installed Ubuntu 7.04 (Feisty Fawn) for home productive purpose. Here is the steps I did to install this Graphics card in Ubuntu.

1. Plugged-in the Graphics card in AGP Slot of motherboard. (This card is AGP 8X speed, though my motherboard (Intel 82815) supports upto 4X AGP only. Since nvidia cards are backward compatible, it fits perfect with my motherboard) Connected the monitor to D-SUB connector of this card.

2. Booted the machine. Bios automatically detected the AGP Card and switched over the default display to this card.

3. No GUI desktop login manager. X windows failed due to mismatch between current display hardware and existing /etc/X11/xorg.conf. xorg.conf has entries for Intel i810 driver which is built-in graphics chip.

4. Looking into the xorg.conf, I came to know the following command to reconfigure the X server.

5. $ sudo dpkg-reconfigure -phigh xserver-xorg

6. $ sudo /etc/init.d/gdm restart

7. Just logged into my gnome desktop. At this stage this card is driven by open source driver called “nv”.

8. I wanted to check the power of this card. So clicked System->Preferences->Desktop Effects. I was offered to enable and install proprietory nvidia driver to get better performance. I said yes. It installed “nvidia-glx” driver from restricted repository.Then it prompted for reboot.

9. Upon reboot, it is performing wonderful. I checked both compiz and beryl window managers, both work well.

Note: If Ubuntu is able to detect the newly plugged-in graphics card and configure the xorg.conf accordingly, it would be wonderful. Hope in the future version we can expect it.
