I have Ubuntu 19.04 with Linux 5.0 (also Linux 4.15-oem installed). I use NVIDIA Proprietary driver. I have i7 6300hq (I think it does not matters) and NVIDIA GTX960m. I added to kernel acpi_osi=Linux. On kernel 5.0 when I suspend on Intel profile when I'm waking laptop starts rebooting (but the led is blinking before wake). When I change to NVIDIA profile It suspends and starts normally but wallpaper changes to black and some purple and pink pixels noise (???). When I change to 4.15-oem kernel It suspends normally on Intel profile without any bugs but the NVIDIA PRIME profile don't work. I can change to NVIDIA but after reloging it does not make any change, I am still on Intel.

I've searched to this issue but I found that it was bug in kernel 4.4 and it was on older Ubuntu versions.

PS. I'm using NVIDIA 418.56-0ubuntu1 driver. It is signed in 19.04 as proprietary, tested.

  • What version Nvidia driver? – heynnema May 2 at 18:04
  • @heynnema, I've added post scriptum to question. It's 418. – patrykbajos May 2 at 18:45
  • If you open Software & Updates, select the Additional Drivers tab, what choice do you see? – heynnema May 2 at 19:06
  • @heynnema I can see NVIDIA 418 (proprietary, tested), 410 (proprietary), 390 (proprietary), nouveau (open-source). – patrykbajos May 2 at 19:25
  • Now I switched to nouveau and as inxi -G says nouveau module is not loaded, I have only i915 driver. Now suspend works as it should but I want to have fully working proprietary driver. – patrykbajos May 2 at 19:27

From the comments...

There seems to be a problem with the Nvidia 418.56 driver and Ubuntu 19.04. The user will contact Nvidia support.
