My pc, gtx 750 with nvidia 347 driver ubuntu gnome 14.04, boots only to black screen. When I look into the /var/log/syslog I get this error with the nvidia driver.
nvidia: module license 'NVIDIA' taints kernel. nvidia: module verification failed: signature and/or required key missing - tainting kernel init: plymouth-upstart-bridge main process (223) terminated with status 1 gdm-simple-slave: Failed to give slave programs access to the display. Trying to proceed.
I installed the drive by hand stopping gdm and the install process did not create any error. The plymouth error is very strange since I define "noplymouth" in grub.
I am not very familiar with error messages. What do those messages mean and more importantly how do I fix it? Is there a way to get rid of plymouth all together since it only displays the ubuntu logo at the beginning.
thanks for reading
Update: Just read that the kernel taint message is normal and nothing to worry about. The plymouth message is still strange and it is multiple times in the syslog file.
