Pc: Dell Precison 5510

Ubuntu version: 16.04

Graphic cards:

  • Intel Corporation HD Graphics P530
  • NVIDIA Corporation GM107GLM Quadro M1000M

I updated the microcode firmware for Intels graphic card with their tool. Then I installed the nvidia-370 driver with nvidia-prime like so:

sudo apt-get install nvidia-370 nvidia-prime

At reboot I had a login loop. Then i switch in TTY the GPU to use like suggested in the comments:

sudo prime-select intel

I can login again. If I look at /etc/modules I see this:

 i915 
 bbswitch 
 nouveau 
 nouveau

When i am opening NVIDIA X server Settings, i don`t see any GPU to select.

I posted a question about another problem that affects me. Maybe they correlate with each other?

what can I try?

How should i set GRUB_CMDLINE_LINUX_DEFAULT in /etc/default/grub?

if I sudo apt-get update I receive this massage at the end: W: https://download.01.org/gfx/ubuntu/16.04/main/dists/xenial/InRelease: Signature by key 09D6EF97BFB38E916EF060E756A3DEF863961D39 uses weak digest algorithm (SHA1)

  • When Nvidia drivers were installed Nouveau drivers should have been blacklisted this might have caused a conflict but probably something else is going on. You didn't need to purge nvidia* in TTY, you could have used sudo prime-select intel in TTY and kept your drivers around for later. – WinEunuuchs2Unix Oct 05 '16 at 10:50
  • should i blacklist Nouveau before i install the nvidia driver? – sepplhans Oct 05 '16 at 11:13
  • @WinEunuuchs2Unix Now i did it like you said. Intalled nvidia-370, reboot and there again the login loop. Then TTY and sudo prime-select intel, reboot and i can login again... If i open etc/modules i see i915; bbswitch; nouveau; nouveau. So why two times nouveau? And should there a 'nvidia' also? – sepplhans Oct 05 '16 at 11:26

    You should purge and blacklist nouveau to remove it from the equation forever. Eliminate the clutter... Don't have time to fully answer your question now, will look later. – WinEunuuchs2Unix Oct 05 '16 at 11:49
  • @WinEunuuchs2Unix Can you provide me please a full description how to proceed to get everything clean? – sepplhans Oct 06 '16 at 09:55
  • I wish I knew how. I haven't setup Nvidia drivers successfully myself. Try this link: [http://askubuntu.com/questions/481414/install-nvidia-driver-instead-nouveau] Please pay attention to last answer! – WinEunuuchs2Unix Oct 06 '16 at 10:25
  • @WinEunuuchs2Unix last answer says that there is no need to blacklist nouveau. Tried now nvidia-367, same login loop. Im using ligthdm as windows manager and grub setting GRUB_CMDLINE_LINUX_DEFAULT="noplymouth". – sepplhans Oct 06 '16 at 11:48
  • Unfortunately I'll be away from my computer all day and can't research anything. :( – WinEunuuchs2Unix Oct 06 '16 at 12:23
  • It actually says you don't need to blacklist nouveau IF you install the drivers using 'System Settings', 'Software & Updates', 'Additional Drivers' but you used 'sudo apt-get install' – WinEunuuchs2Unix Oct 06 '16 at 17:33

    I have the same issue! Since I don't urgently the nvidia card under linux, I just purged the nvidia drivers for me the moment, but this is far from ideal. When I first installed ubuntu 16.04 (last april) I also installed the nvidia drivers with the systems settings GUI and everything was fine for a while... I can't exactly tell which update broke things – justmyfault Oct 10 '16 at 12:22
  • @justmyfault it would be interesting to install the old dated drivers, but i dont know how... simply taking drivers lower than nvidia-370 ? for examle nvidia-367? – sepplhans Oct 10 '16 at 13:22
  • @marsUbuntux at the moment I have the problem WITHOUT any nvidia driver installed... But since ubuntu 16.10 came I think I'll try to update in a few days and see what happens – justmyfault Oct 21 '16 at 10:51
  • @justmyfault it would be nice if you can report here after update. thanks – sepplhans Oct 21 '16 at 12:25
