I can boot the usb live Ubuntu 12.04, but when I try to launch the installation program from the desktop nothing happen. I don't know how to proceed to check what is going on but I also tried to use the system monitor and everything works except when i click on the "system" tab, in this case the monitor stops and disappears.

Does anyone know the solution for this issue ?

Is ubuntu compatible with Dell lattitude laptops?

There might be some problem with the ISO image you downloaded. Please compare the md5sum of the image you have with the checksum provided on the server.

To do this:

1. Note down the md5sum from the Ubuntu which you can find on .

2. Calculate the md5sum of the iso image you downloaded using the command md5sum filename.iso where filename.iso is your image file.

3. Compare the two sums.

If the checksums are same, you might want to check out the installation instructions on .

To know more about checksums, check out the wikipedia article on Checksums.

You can also compare the sha1sum or sha256sum.
