After installing the proprietary Nvidia drivers (GEForce 730), normal boot hangs during splash loading. Alternate boot selecting Recovery Mode / Resume normal boot takes me to the login screen. The behavior is identical to that described in these other issues:
New install of Ubuntu 15.10. I have literally done nothing but configure my drives and install keepassx2 before Nvidia installation.
I originally tried to install the drivers from Nvidia, but the install never started because I couldn't overcome the problem of nouveau being loaded. So I used the repository instead:
sudo add-apt-repository ppa:graphics-drivers/ppa
to install the 355 driver version.
That is when the current problem started. I also tried using the Additional Drivers app to change the 358 driver version.
I tried following the suggestion in the first referenced issue to slow down boot with a sleep command. But I think our systems aren't identical. I have a lightdm file, not a lightdm.conf file. And instead of
exec lightdm it is a paramaterized
lightdm start command. I may have done it wrong, since when it didn't work I changed from
sleep 2 to
sleep 90 with no effect. And by "no effect" I mean it doesn't fix the problem, and when I boot with Recover Mode / Resume it doesn't seem to add 90 seconds to the boot time.
/etc/init.d/lightdm [snip] else log_daemon_msg "Starting X display manager" "lightdm" #To fix boot hang / starts lightdm too soon sleep 90 start-stop-daemon --start --quiet $SSD_START_ARGS \ || log_progress_msg "already running" log_end_msg 0 fi
I also (inadvertently) tried setting the 'nomodeset' parm in grub, in that I had already added that parm earlier while trying to disable nouveau drivers. After I gave that up and went with the PPA installation, the parm was still set. In troubleshooting the current issue, I removed the 'nomodeset' parm from grub, but that hasn't made a difference.
Anyway, the drivers seem to work great...I just can't boot through the normal process. What is failing during boot, and what fix and or workaround can I apply?
