LTS 6.0: black blocks obscuring desktop after login

I just d/loaded Zorin LTS the other day to try on my wife's new laptop that comes with an i5 and nVidia chipset.

Whether I run the live install or install it, after logging in the desktop is obscured with black blocks. Whenever I click to open the "Z" menu or an app, the menu/app opens and is initially visible ontop of the black blocks, but then seconds later the black blocks cover over the menu/app. But if I hover the mouse over where the menu/app was displayed then parts of the menu/app become visible again on top of these black blocks.

I looked to see, expecting perhaps there might be some proprietary driver, nVidia specifically, issues that needed resolving by installing some updates in system setting, but additional drivers icon showed no flags. I thought perhaps a full upgrade/update might well do the trick, but I use a very slow (but free) inet connection and so put off d/loading the additional 200-400Mb of additional d/loads required to update the install for the time being.

I did, however, install both #! (crunchbang) as well as an older xubuntu 13.04 spin I still have kicking around and both distro live installs run fine on the laptop.

Fortunately, for testing purposes at least, there was a problem with the new laptop's bios that would not allow me to boot anything from the boot menu other than the default choice. That is, whenever I would try to hit the down arrow (or any other key for that matter) to select an alternate option, like safe mode, the bios would simply reboot to the boot menu again. I say fortunate because we took the laptop back to the store for an exchange (it was an Acer Aspire) and the staff at the store let me play with several alternate brand laptops with similar specs.The exact same problem with black blocks happened to me with all the laptops I tried to run the Zorin LTS live install on. All of the laptops save one had the nVidia chipset, with the exception having a Radeon chipset instead. Yet, when I ran the #! live install from usb pen, it worked as expected on the three additional laptops I ran it on at the store.

That would suggest to me there was a problem with the Zorin .iso I d/loaded, except I installed Zorin on my main PC as a virt machine in virtbox and it runs fine. Looks good. Exactly what I want for my wife's hopeful gravitation to linux from winblowz.

In the meantime I will d/load cinnamon to see how that runs on the laptop as a possible alternative. I have never personally tried it out, but the screenshots look windows-like enough I suppose, but not as close as the windows-look Zorin has achieved, so I would really prefer to get my wife going using Linux with Zorin if at all possible. So if anyone has any suggs or ideas I would be happy to read them.

OK, first off, did you burn to DVD? Or were you trying through the USB root when installing?

Starting from scratch:

1. Download from here:

http://ftp.nluug.nl/os/Linux/distr/zorin/6/

2. Only use Firefox or Opera to download to ensure a non-corrupt download.

3. Check the md5sum of the downloaded file using winmd5free from http://winmd5.com - how to use it here:

If you downloaded in GNU/Linux, open a Terminal (Ctrl+ Alt+ T), navigate to where the .iso was downloaded to - if 'Downloads' then:

Code:
cd Downloads


Code:
md5sum zorin-os-6-core-32.iso


and wait for the resultant md5sum

Next if in Windows, use 'imgburn' at the slowest possible speed your burner will support: http://imgburn.com - use imgburn.com's own mirror - last in the list!

Finally if you did burn to DVD, have you ever used one of these on the optical drive?

We have had members having issues and it was down to a dirty optical lens! :D
