I want to install debian 8.2 (Jessie) on my msi GT70 2PE Dominator pro computer (which at the moment is running linux mint). The install went smoothly, apparently (after resolving some problems with help from this site!). But, when rebooting after the install, the reboot seems to go well, but it only shows the debian 8.2 blue artwork, without any icons or menus, so I am not able to get anything done. What went wrong, and what can I do?
Maybe I should add that I installed debian with the mate desktop.
Graphics card: nvidia GTX 880 M
EDIT Trying to answer the questions in the one answer. Yes, I see the grub screen with two lines: debian gnu/linux, and advanced options for debian gnu/linux. I choose the first, enter. Then some grub output flashes by (takes some time), and so appears the blue debian screen with a white menuline on top. It has one menu option for default Xsession, or for MATE. I choose MATE, types my user name+password, enter. Then---nothing happens, almost. Well, the white menuline disappears, and the screen appears frozen. The mouse do not work anymore (either the touchpad), the muse marker do not move. But I can hear the cooler works! more than usual. Nothing to do but restart.
