== Troubleshooting == |
|||
=== Keyboard and Mouse === |
|||
A typical case is that their keyboard and mouse don't work. A solution to the problem is: |
|||
#Make sure the the window has the focus (label should say <tt>QEMU - Press Ctrl-Alt to exit grab</tt>). |
|||
#Press <tt>Alt + Ctrl + 3</tt> to enter the terminal mode of the OLPC. |
|||
#Make sure that you're logged in. |
|||
#*If not, just hit <tt>enter</tt> and it'll ask you to. |
|||
#*Login as <tt>root</tt> (no password is required) |
|||
#Type <tt>modprobe i8042</tt> (oddly, you may need to try this multiple times before it works, so ''keep trying!'') |
|||
#Press <tt>Alt + Ctrl + 1</tt> to return to the graphical mode of the OLPC. |
|||
#Your keyboard and mouse should be working fine. |
|||
#*Usually the result is a continuous series of 1's will flow (as if the key is stuck) |
|||
#*Just hit any key (to stop it) and delete the offending 1's |
|||
=== Network === |
|||
Chances are that the network will not be enabled. Following are two possible ways to enable it. |
|||
==== Enabling the Network Alternative #1 ==== |
|||
#Make sure the the window has the focus (label should say <tt>QEMU - Press Ctrl-Alt to exit grab</tt>). |
|||
#Press <tt>Alt + Ctrl + 3</tt> to enter the terminal mode of the OLPC. |
|||
#Make sure that you're logged in. |
|||
#*If not, just hit <tt>enter</tt> and it'll ask you to. |
|||
#*Login as <tt>root</tt> (no password is required) |
|||
#Type <tt>dhclient</tt> |
|||
#Press <tt>Alt + Ctrl + 1</tt> to return to the graphical mode of the OLPC. |
|||
#Your browser / network connection should be working fine. |
|||
==== Enabling the Network Alternative #2 ==== |
|||
The steps below work on QEmu regardless of which operating system you are running. |
|||
'''If you are having trouble getting an internet connection inside QEmu:''' |
|||
Get the image running in QEmu so that you can see the normal view with the XO icon in the middle. |
|||

|||
Make sure your mouse is active in QEmu, then press ctrl+alt+2 together. |
|||
This will bring up a screen like a command line, called the QEmu monitor. |
|||
Type the following: |
|||
sendkey ctrl-alt-f1 |
|||
And press return. |
|||
Then with the keyboard hold down the following keys: '''ctrl+alt+1''' |
|||
Another text based screen will appear, asking you to log-in. Sometimes there can be an extra "1" after the word "Login:", just delete it. Type '''root''' and press return |
|||
Then type: |
|||
dhclient |
|||
You should see the screen fill with text. |
|||

|||
Some of the numbers have been removed from the screenshot above - they're not important. |
|||
Then hold down the following keys on the keyboard: '''ctrl+alt+2''' |
|||
and type the following: |
|||
sendkey ctrl-alt-f7 |
|||
Then using the keyboard, hold down the following keys: '''ctrl+alt+1''' |
|||
Now open the browser and you should have internet access. |
