Ubuntu on a Samsung X05

My laptop is a Samsung NXO5. This was not made available to Portugal by Samsung. This is a very classy, lightweight and thin laptop.

Specs:

  • Processor: Intel Pentium M 1.4 GHz
  • Chipset : Intel 82855 GM (Montara)
  • RAM: 512 MB DDR
  • Graphic adapter: Intel Extreme Graphics 2
  • Interfaces: PCMCIA/Card Bus, USB (2x), VGA, LAN, modem, Wireless-LAN (802.11b), S/PDIF, analog sound, Memory Stick

OS:
The advised OS for this Intel Based laptop is MS Windows XP (go figure why!). I have it running in Ubuntu 5.10 (also known as the Brezzy Bagger), without any problem, every thing worked right out of the box (only the modem and the Memory Stic wheren't tested yet….)

The only problem that i found was that my Teac DVD Multi-Recorder did not had the DMA activated. So what i did was:

  • On my terminal:

~$sudo hdparm /dev/hdc

note:

  • This command let's you check the state of a certain drive, in this case my DVD drive.
  • Hdparm let's you get/set drive parameters (for more information check this link or wright "man -k hdparm" on your terminal).
  • To execute it, you will need super user (sudo) permission.
  • The /dev/hdc is the path to my DVD drive.
  • you should get something like this:

/dev/hdc:
IO_support= 0 (default 16-bit)
unmaskirq= 0 (off)
using_dma= 0 (off)
keepsettings= 0 (off)
readonly= 0 (off)
readhead= 256 (off)
HDIO_GETGEO failed: Invalid argument

  • If you have the DMA off (using_dma = 0 (off))then let's activate it

~$sudo hdparm -d1 /dev/hdc

note: This command will enable the DMA, but you would need to do it again every time you reboot the computer, if you wanted to enable DMA.

  • To activate the DMA every time you reboot the computer you need to edit the hdparm.conf file so on the terminal window:

~$sudo cp /etc/hdparm.conf /etc/hdparm.conf.enable-dma.backupnote: This command will backup the previous hdparm.conf file. This is always a good politics. Only Super User can edit the files on this OS folder , that is why you will need sudo

~$sudo gedit /etc/hdparm.conf

note: Gedit is the default ASCII text editor for Ubuntu. Something like Notepad, but far better.

  • Then you just need to add this lines to the end of the file

/dev/cdrom {
dma= on
}

note: the information on the file is very good to learn more about setting a drive configuration.

    I have the same laptop and I am running Debian Sarge. I was wondering if under Ubuntu the battery monitor works well, because I haven’t been able to set mine up yet.

    Good documentation for the dvd dma!

    hi there:

    fist of all thanks. and sorry for the delay to respond, i had some problems with my ISP, that seems to be over now.

    if you are refering to the laptop battery monitor (fn+f2), well i never been able to put it to work under linux, but i really don’t care and it does not make me any difference.

    to measure my laptop battery i use the Power Manager 2.14.3 for gnome, it is the default aplication on ubuntu 6.06, and it works very well right out of the box.
