Sddm fails to open in hybrid and nvidia mode.

[candyclaws]

I am using void linux, and it began after installing and switching to integrated for the first time. Now I am completely unable to use my nvidia gpu. I have tried reinstalling all of my nvidia drivers and dkms, I have checked all of the blacklists, and while I can access my nvidia gpu in other modes, sddm will not launch.

Have you tried with --reset-sddm?

[candyclaws]

I tried --reset-sddm, I tried deleting all the files it created, I tried everything I could think of to get it working so in the end I just backed up my home folder and reinstalled, maybe it's a void linux thing, they do seem to do things different than other distros

Is SDDM causing a black screen with frozen text cursor (not blinking) on boot?

I used to be able to use envycontrol on my previous system install without a display manager or desktop environment. Now with SDDM and Plasma 5, I can't use any of integrated/hybrid/nvidia. It just freezes on boot. I have to chroot and run envycontrol --reset to be able to boot again. Not sure if SDDM is causing this, but maybe one of you know.

What distro are you using?

[gavsiu]

Arch Linux.

@gavsiu can you switch to Nvidia mode using --verbose flag?

PD: you can --reset again before rebooting but I want to see the output

What happens if you remove this line from /etc/modprobe.d/nvidia.conf ?

options nvidia NVreg_UsePageAttributeTable=1 NVreg_InitializeSystemMemoryAllocations=0

[gavsiu]

I also have this in my /etc/modprobe.d/nvidia-power-management.conf

options nvidia NVreg_PreserveVideoMemoryAllocations=1 NVreg_TemporaryFilePath=/var/tmp NVreg_DynamicPowerManagement=0x02

Does this need to be removed?

Try to rename it to .bak instead of deleting it, I'm just trying to test something

[gavsiu]

Renamed to .bak, deleted line from nvidia.conf. Still froze the same way.
