I've been having this problem since I installed genuine Nvidia GeForce drivers for my graphics card.My system boots normally, but when the login screen should show only black screen shows.The only solution to start gdm3 is to restart X server by typing telinit 3; telinit 5. Then gdm3 starts normally.Did anyone had the same problem, and, if so, how did you solve it?
GDM doesn't start - Kali Linux
gnome;kali linux;runlevel;gdm3
what is your default run level, AFAIK to start gui you need to be on run level 5check via runlevel command.you can also insert runlevel in grub.cfg, open as root/boot/grub/grub.cfgfind line start withlinux /boot/... root=... ......insert 5 at last of it, likelinux /boot/... root=... ...... 5save, reboot.
