after upgrading my machine to 18.04 from 16.04 I noticed that my Nvidia driver is no longer installed and after I reinstalled the driver I'm getting a black screen I've got such a problem before and fixed it with manually installing the Nvidia driver instead of using autoinstall or apt-get install Nvidia (number goes here). I've tried all the method of installation mentioned here and read almost all topic about this problem on askubuntu, its almost 2 weeks now and I'm unable to find a solution to this problem

edit i fixed the problem by updating the kernel

i've spent 3 weeks now with this and the problem was the grub boot loader needed to be updated after the linux-header update i used update-grub every time but i fail to notice that the main grub boot loader was on another distro so i needed to update that grub and that fixed my problem. all thanks to @BarBar1234

  • when does the black screen appears? during boot, after boot? or else? – Jastria Rahmat Feb 24 '19 at 22:52
  • black screen appears after I select Ubuntu from the grub and a few seconds later the keyboard num pad light start working which means ubuntu has loaded but i can see nothing other than a black screen even ctrl + alt + f1 / f2 --> f12 goes no where – LeLouch Feb 25 '19 at 09:20
  • 16.04 -> 18.04 upgrades rarely run smooth. I can't get mine working as well. Consider a fresh install. – Pilot6 Feb 25 '19 at 20:32

    Upgrades typically want you to disable 3rd party repos. If you did (the graphics ppa?), did you re-enable them, since 415 is not in the standard repos. – ubfan1 Feb 25 '19 at 20:48
  • @Pilot6 fresh install is not an option – LeLouch Feb 25 '19 at 22:42
  • @ubfan1 yes I did re-enable them and tried with and without the repo auto and manual install and getting always the same problem – LeLouch Feb 25 '19 at 22:44
  • Check all files in /etc/modprobe.d for blacklist nvidia lines (except OK to blacklist nvidiafb) -- remove them if any. What happens when you add the nvidia driver with modprobe nvidia (presuming you have the driver, and it's not getting used)? Post the output of lsmod | grep nvi (four nvidia... modules expected). Did you ever try booting an older kernel? – ubfan1 Feb 25 '19 at 23:07

disable Secure Boot in BIOS, as Secure Boot blocks the nvidia modules from being loaded in this case.

  • found secure boot already disabled – LeLouch Feb 25 '19 at 22:57
  • Ok, and have you tried the grub option nouveau.modeset=0 already as well? – NetIceGear Feb 26 '19 at 00:11
  • YES , i used that to uninstall all the nvidia drivers and log back to my desktop – LeLouch Feb 26 '19 at 00:27
  • Ok, could you provide the printout of glxinfo -B when you have modeset set to zero. I can't recall if glxinfo is already included, but if not you should be able to get it from the main repo. Also, please add uname -a output for additional reference – NetIceGear Feb 26 '19 at 01:19
  • thanks for the reply nouveau.modeset=0 didn't help at all but i sed nomodeset=0 to go back to desktop and i've updated what you asked for – LeLouch Feb 26 '19 at 20:21
  • Ok, I see that you have a whole selection of drivers you attempted to use, can you remove all nvidia drivers, and load only the xserver-xorg-video-nouveau one and then try the nouveau.modeset=0 grub parameter. also make sure your linux-headers are up to date! – NetIceGear Feb 26 '19 at 20:45
  • after I removed all Nvidia driver and made sure I was booting properly using nouveau I tried nouveau.modeset=0 on the grub parameter and went back to the same black screen . – LeLouch Feb 26 '19 at 21:21
  • Sorry, I edited the last comment I posted right after posting, but didnt realize there was only a 5 min window for editing and it didnt get updated. The nouveau.modeset=0 will of course cause a black screen when nouveau is the only nvidia driver in use. MY updated comment went something like this: purge all propriatary drivers and use nouvedau and test reboot, then re-check to make sure that the lshw -numeric -C now lists driver=nouveau in the line with configuration: latency and glxinfo -B updates the driver information as well. – NetIceGear Feb 27 '19 at 02:14
  • However, I just noticed the last part of the shell output you provided namely $uname -a . How do you have such an outdated kernel version if running Ubuntu 18.04? The 18.04 uses 4.15 kernel version. Please post output of $sudo apt search linux-headers-$(uname -r) because your headers seem very outdated and your gpu is a recent model. I would just proceed with header update and then let dkms build the nvidia driver accordingly: $sudo apt-get update && sudo apt install linux-headers-$(uname -r|sed 's/[^-]*-[^-]*-//') nvidia-driver – NetIceGear Feb 27 '19 at 02:26

I tried countless solutions found on the internet, the only thing that worked for me was to:

  • backup /etc/X11/xorg.conf to /etc/X11/xorg.conf.old
  • similarly backup /etc/X11/xorg.conf.d/ directory, if it exists
  • and then cp -r /usr/share/X11/xorg.conf.d /etc/X11/
