First of all, make sure you did not choose "minimal install" when installing the system
When starting, add "nouveau.modeset=0" in the kernel parameters
In the case of NVIDA dual graphics cards, https://elrepo.org/tiki/bumblebee + "optirun bash" is the most reliable solution I have seen. disable nouveau + official driver is prone to glx problems
I have encountered this problem. I couldn’t enter the system after installing centos6 before. Then I installed debian-7.8.0, and the screen still couldn’t be entered. The error message was also nouveau, which means that the compatibility of this driver is not as good as the official driver. Later, I added the parameter x11failsafe to the kernel line in Debian's grub menu, which means that the graphics card driver is not loaded, so that I can modify the system after entering the desktop; or I can also press ctrl+alt+F1 to switch to the console. I logged in as root and later reinstalled the system and it was also successful. Then delete all nouveau related packages and install the nv official driver (download it in advance and put it on the hard disk, it will be automatically blocked during installation/ Disable nouveau), and then restart and you can enter the desktop normally.
It should be noted that if you install the official nvdia driver, you need to terminate all Xorg processes and then install it on the console. For the gnome3 desktop, you can terminate the X process by ctrl+alt+F1 and then use the command /etc/init.d/gdm3 stop. Others You can probably use key combinations on the desktop. I don’t know if you need to search for details. In addition, before installing the n official driver, you need to install packages such as linux-kernel/kernel-source/kernel-header. The names are different depending on the system. If you don't install this, you won't be able to compile and generate the driver you need. You also have to search for the installation method corresponding to your system. Finally, when installing the nv driver, if you are prompted about the gcc version problem, you can choose to ignore it. Generally, it will not have any impact. In short, just follow the instructions to ensure everything is safe. I wish you good luck...
