I’m having a few issues booting Ubuntu on my NC20. I’m not trying to boot the Netbook Remix, because it requires an Atom processor. I’ve downloaded the ISO, made a bootable stick with UNetBootin, and successfully booted from the USB by changing the BIOS. However, after I get the Ubuntu “loading” screen. My display starts painting colourful lines and flashing on and off, rendering my computer unusable. I’m wondering if this is a problem with my display drivers…. Has anyone else had this problem?
Hi, did you take a look at https://help.ubuntu.com/community/NC20 ? It says – among other things – “When you try to run the live cd the graphical login will not work and you’ll need to build the OpenChrome driver from svn or install a working package from the Debian distribution”. Did you try that ?
I installed Ubuntu (Karmic Koala, the latest) on my NC20 without any major problems. I’m also returning Windows for a refund from Samsung, but that’s another story… 😉
If you want to install it, use the guide linked to in the previous reply. I booted Koala from a USB CD drive. The bootup selection works fine, but as the computer booted, the screen started cycling through primary colours: red, green, blue; as well as white and grey. Wait until the boot process is complete, then press Ctrl+Alt+F1 to go to a console screen.
At the console, just go through the ‘Video / Graphics’ section of the wiki. It looks challenging, but it’s clearly explained and you just have to type each entry exactly as shown.
(BTW, you’ll need an internet connection for this: I used an ethernet cable connected directly to my broadband router.)
I finished with the wiki section ‘Restart GDM and install Ubuntu’ (the rest of the wiki refers to a previous version of Ubuntu). The liveCD worked from here on without a hitch. Ubuntu installed quickly, and the display worked perfectly when I rebooted. Everything else I’ve tested so far works ‘out-of-the-box’.
Ubuntu really is an excellent match for this computer. It’s a shame (I would even say OUTRAGEOUS) that Samsung don’t have an option for pre-installed Ubuntu!
The instructions mentioned in the Ubuntu Community for NC20 seem work, except that when I got to the following, it didn’t allow me to save. (Eventually I had to answer “No” to “Destroy all the changes” when I was instructed to save the file but couldn’t save it, nevertheless, it worked after GDM restart and the GUI showed up and I went on to install Ubuntu 9.10). After the installation is finished and my NC20 rebooted the screen started cycling through primary colours again. When I use the sudo nano /etc/X11/xorg.conf commend to edit as suggested below, again, I just couldn’t save my changes and it give me a [Error writing /etc/x11/xorg.conf: No such file or directory] message.
Anyone of you who get pass this please offer some help as to how to save the changes to make the GUI work, many thanks.
Quote:* Edit the Xorg configurationYou can use the nano editor or any command line editor that you are comfortable with to make the changes
sudo nano /etc/X11/xorg.conf
This is my configuration which is minimal but gives the full 1280*800 resolution with 32-bit colour. The key settings are specifying the openchrome driver and the activedevice option.
Section “Device”
Identifier “Configured Video Device”
Driver “openchrome”
Option “ActiveDevice” “LCD,CRT”
EndSectionSection “Monitor”
Identifier “Configured Monitor”
EndSectionSection “Screen”
Identifier “Default Screen”
Monitor “Configured Monitor”
Device “Configured Video Device”
DefaultDepth 16
EndSectionI posted these instructions that worked for me in ‘Linux and other OS’ a couple of days ago:
1. download LinuxLiveUSB for Windows
2. use a USB stick of 1Gb or more (I used a 1Gb stick)
3. run LinuxLiveUSB, select to download Ubuntu 9.10
4. in LinuxLiveUSB deselect ‘Enable launching LinuxLive in Windows’ to get some more needed persistent space on a 1Gb stick
5. select maximum persistant space (on a 1Gb stick about 300Mb). If you are using a bigger USB stick you can select more space but it isn’t needed
6. create the bootable stick
7. plug in an ethernet cable for network access for the remaining steps
8. boot your NC20 with the USB stick
9. at the end of the boot and during the Ubuntu login sound the screen will cycle through colors because a suitable video driver is missing – press CTRL-ALT-F1 to drop to the terminal
10. follow ‘Build from SVN’ instructions from Ubuntu NC20 wiki
11. when you get to the desktop you can play with the system or install to the hard diskFinally, my Ubuntu OS is working as it should… 🙂
It turned out that with the latest Ubuntu ver. 9.10, one only needs to “Build from SVN” RIGHT AFTER the installation process is completed, as suggested in the Ubuntu NC20 Wiki, for the GUI to work. NC20/Via users don’t need to modify the XORG.CONF as suggested in the Ubuntu NC20 WiKi. My screen resolution is perfectly aligned at 1280×800. This actually save some work for all the NC20 users who want to install Ubuntu.
Anyway, many thanks for all of your suggestions here.
