After the screen went blanc, it will intermittently not give a login prompt when you wake the screen.

I have Ubuntu 19.10 installed on a Dell Vostro 3670 (Intel® Core™ i7-8700 CPU @ 3.20GHz × 12 ). The system has a Nvidia video card and the Nvidia 435.21 driver is installed.

I found a potential solution for Unbutu 18 (18.04 Screen remains blank after wake up from suspend):

$ sudo gedit /etc/default/grub

(change line to - GRUB_CMDLINE_LINUX="nouveau.modeset=0")

$ sudo update-grub

This did not work. Any other solution? Best wishes, Gert Kruger

  • nouveau.modeset=0 won't work for your Nvidia card. Try changing your /etc/default/grub file to... find "quiet splash" change to "quiet splash nomodeset", then sudo update-grub. This change should be considered temporary, and only for testing. Your screen resolution may be messed up during this test. – heynnema Jan 22 '20 at 16:36
  • Thanks, I tried this. It still gives the same issue. Any other suggestion? – Gert Kruger Jan 29 '20 at 06:29
  • Is your video set to use the Intel video card or the Nvidia video card? What model Nvidia card? Also show me sudo dmidecode -s bios-version. In Software & Updates, Additional Drivers tab, tell me what you see... probably easier in a screenshot... load it to imgur.com if you don't know how to add it to your question. – heynnema Jan 29 '20 at 08:36
  • Thanks for your reply! When I use $ lspci | grep VGA I get the following output:

    01:00.0 VGA compatible controller: NVIDIA Corporation GP107 [GeForce GTX 1050] (rev a1)

    Bios version: 2.13.0

    Additional drivers: NVIDIA Corporation: GP107 {GeForce GTX 1050]. Using NVIDIA driver metapackage from nvidia-driver-435.

    Hope that helps!

Let's start with:

Please see https://www.dell.com/support/article/za/en/zabsdt1/sln171755/update-the-dell-bios-in-a-linux-or-ubuntu-environment?lang=en for how to do this in a Linux only environment.

  • Thanks! I managed to do both and after about 2 days I have not observed the same blank screen issue.

    It was a bit challenging to update the bios as one don't get a Linux option to download. I followed the instructions from https://www.dell.com/support/article/za/en/zabsdt1/sln171755/update-the-dell-bios-in-a-linux-or-ubuntu-environment?lang=en

    and just copied the Windows bios exe file on a flashdisk. Thanks a lot! Gert Kruger
