First off - thanks for taking the time to read and answer.
okay.. after about 18 hours of work (with a sleep of 5 hours) - I got it to work after about 5 installs & I was able to install only ubuntu 12.04.
My Laptop: HP Pavilion g6 Core i3 with Intel graphics (think it is the 3000 series if not mistaken, 64 bit) & wide screen (1366x768 resolution).
Here is what I did to install. Flashed the live usb with ubuntu 12.04. Boot the ubuntu with the "nomodeset" option. If I tried the install directly, it will not work. So you have to boot and then install. Then start the installation and have a good internet connection. The linux mint always stopped at the configuring hardware even though my internet was good and I allowed it to download all the packages
It installs everything. But then there were two issues. One - there was always black screen when it boots & second the resolution was 1024x768 which was awful for my wide screen.
Then go to the Intel Linux drivers website and download the drivers. Make sure you have all the pre-requisite set and install the same. You have to reboot a couple of time. So ensure to update the grub with the nomodeset option. If you are unable then keep on pressing the shift key to get the grub loader, edit it ('e' key) and add the nomodeset option.
Once the installation of drivers is complete, update using the Update manager. It will also provide the Intel graphics driver. I have updated my maching with xorg. Then add a couple of lines in the grub with following options
Make sure this is between the quite and splash. If I had the acpi_osi at the end of the grub it did not work. So let it be inbetween the quiet and spash. With this I was able to get rid of the nomodeset and I have a resolution of 1360x768 which was better and the fonts are also good. I had also copied the true type fonts to the usr/grub to make it work.
Now - the issue is the function key combinations which is not working (e.g. Fn + brightness). I am yet to figure that out. I think I will do another post if that is not working. I am once again not sure why Linux Mint failed to install (which is version of Ubuntu if I am not mistaken) to proceed with installation.
Hope this helps people.
