I currently have ubuntu 12.04 and the settings -> Details does not detect the graphics card, however I get the graphics card info with:
lspci -v | grep -i vga 00:02.0 VGA compatible controller: Intel Corporation Xeon E3-1200 v2/3rd Gen Core processor Graphics Controller (rev 09) (prog-if 00 [VGA controller])
I want to upgrade Ubuntu but I get the following message:
Your graphics hardware may not be fully supported in Ubuntu 14.04.
Running the 'unity' desktop environment is not fully supported by your graphics hardware. You will maybe end up in a very slow environment after the upgrade. Our advice is to keep the LTS version for now. For more information see https://wiki.ubuntu.com/X/Bugs/UpdateManagerWarningForUnity3D Do you still want to continue with the upgrade?
Is it safe to upgrade anyhow, would this graphics card give me problems as it states in the message or is that message displayed because it doesn't detect the card? Any help appreciated

I tried to upgrade skipping the warning and it didn't do the upgrade do to another error "An unresolvable problem occurred while calculating the upgrade.".
So I turned off my computer and this morning when I turned it on there was a red forbiden sign on the top right corner of the desktop, I selected from the list 'check for updates' and the computer started upgrading to 14.04, however after one hour and almost at the end of the process the upgrade halted with a new error. I opened the terminal and did apt-get update, apt-get upgrade, it has been upgrading now for another hour and I see messages like "Unpacking ubuntu-docs (14.04.5) over (12.04.6) ..."
at the end: Errors were encountered while processing: /var/cache/apt/archives/autokey-common_0.90.4-1_all.deb
I tried to do sudo apt-get install mesa-utils and it did a lot of things for a while ending with this:
Errors were encountered while processing: nvidia-340-updates
