|style="text-align:left" width="80%"|Most desktop systems have on-board network capabilities. Sometimes, this hardware can be bad.  In the case that you have the ethernet chord properly connected to the ethernet plug in the on-board outlet and you don't get a connection, check the BIOS settings to ensure that the on-board networking feature is enabled (there are several types of BIOS environments, so you may have to do some investigating).  If all looks well and you still don't have a connection, try installing a network card.  You will be able to find one in the middle island with other cards, tools and drives. Installing a network card will usually disable the on-board, but reboot and check the BIOS setting to ensure that on-board networking is disabled, and also ensure that the network card is recognized in BIOS.

Miscellaneous Troubleshooting

Steps

Notes and Detailed Instructions

When there is no Internet connection while updating software (i.e. no network connection)

First, double check that your ethernet cable is securely plugged into both your system and the wall jack.

Next, right-click the Network icon on the top panel, next to the time and date, and ensure that Networking is listed as Enabled. Then left-click the Network icon and see if an option appears under Wired Connections (it should say something like auto eth0). If nothing shows up, check the BIOS settings to ensure that the on-board networking feature is enabled (there are several types of BIOS environments, so you may have to do some investigating). If all looks well and you still don't have a connection, try installing a network card. Installing a network card will usually disable the on-board, but reboot and check the BIOS setting to ensure that on-board networking is disabled

"I have optical drive issues"

In most cases, if an optical drive isn't being recognized in a system, or isn't being responsive in some way, the most expedient thing to do is shut down the system, yank out the optical drive, and replace it. If it's a rewritable drive (CD/DVD-RW), mark a small X in Sharpie on the drive and put it back into its appopriate crate. If it's just a readable drive (CD/DVD-ROM), go ahead and put it in the recycle bin underneath the workbench.

If you are still having issues after having replaced the optical drive, then grab a build instructor to look over your connections and help you further troubleshoot the problem, or look through the Optical Drive troubleshooting page on the wiki.

"The system will not complete a reboot. It just hangs on the Ubuntu screen. Shutdown works fine."

GRUB is the boot loader package responsible for starting up and shutting down your computer. Try editing the following GRUB configuration file and see if it makes a difference. HINT: if you hit the Esc key while your computer is booting up or shutting down during the Ubuntu splash screen, you may get more text information about what your computer is doing. If you're not comfortable working in a terminal, grab some help on this one.

In a terminal, type: 

sudo gedit /etc/default/grub

Find the line 

GRUB_CMDLINE_LINUX_DEFAULT="splash quiet"

and edit it to read: 

GRUB_CMDLINE_LINUX_DEFAULT="reboot=bios splash quiet"

Save and exit. In a terminal, type: 

sudo update-grub

Shut down the computer, power on again and try rebooting. Is fixed, no?

"In BasicCheck, I see less RAM reported than I have installed."

If you have are working with the Ubuntu OS, 32-bit extension, and your system has more than 4G of RAM installed, the basiccheck script will not recognise the additional RAM beyond 4G. Open a terminal and type the following command: "sudo apt-get install linux-generic-pae linux-headers-generic-pae" and press enter (enter default password to confirm.) Reboot the system, run basiccheck again and the memory check should recognise the full amount of RAM.

"The XUbuntu splash screen does not show because of a Nvidia chipset"

If the computer just displays a blank screen and then the Display manager you can try the following to add a boot progress splash screen.

STEP 1: 

   apt-get install v86d hwinfo
   hwinfo --framebuffer

STEP 2:

edit /etc/default/grub and after the GRUB_GFXMODE= line add another line containing: 

 GRUB_GFXPAYLOAD_LINUX=1280x1024x24

or 

 GRUB_GFXPAYLOAD_LINUX=1024x768

or something that matches a mode provided by hwinfo.


STEP 3: 

  echo FRAMEBUFFER=y > /etc/initramfs-tools/conf.d/splash


STEP 4: 

  update-initramfs -u
  update-grub2


STEP 5:

reboot


Notes:

You might also need to put something like the following line: 

uvesafb mode_option=1280x1024-32@60 mtrr=3 scroll=ywrap

into /etc/initramfs-tools/modules and run update-initramfs -u again.
