after newset updates (recently ) sddm blank screen

I rebooted my laptop and I get blank black sddm.
I notices the optimus led on my laptop was white (meanin the desicated gpu, nvidia, was running)
removed the nvidia 390xx (recently my gpu went from new to old wink ) and rebooted and it fixed the issue.
I also noted that when in blank screen ,if I try to restart bumblebeed service it give the error that nivida_drm.so (or something like that) is in use and cant restart.

any way to get nvidia working again?

if I keep nvidia and disable sddm, after reboot I can restart bumblebeed and the optimus led goes blue (meaning intel gpu is working) and I can startplasmacomposer (weirdly I cant use startkde because it gives the error $DISPLAY not set or cannot connect)

Please specify all the package version involved and include the pacman.log for the update that produced the issue onwards.
Edit:
Also the exact error from bumblebeed,  the xorg.logs and the journal output for sddm.

Re: after newset updates (recently ) sddm blank screen

wow this escalated quickly.
I removed sddm and installed gdm and updated system again(new mesa and xorg)
and then I couldnt even login anymore.:( 
the tty1 was busy and switching to tty2 would switch back and forth between tty1 and tty2 so fast I couldnt even enter my password.
using a usb with archlinux boot I tested many combination and the now only with nvidia-390xx removed I can login.
tried again with sddm and it was like gdm again.
so it is not a sddm or gdm issue.
it is a nvidia issue

If I find out how to switch kernels I will test with kernels.

this all happended after nvidia moved the support of my GT 550m from 391 to 390xx legacy

UPDATE:
it also happens with linux-lts and nvidia-390xx-lts


yaourt -Qs nvidia
community/bumblebee 3.2.1-17

Re: after newset updates (recently ) sddm blank screen

@rezad This may help you, I recently got my bumblebee working after like 2 months of it bring broken:

sudo systemctl stop gdm
sudo pkill -f X -9
sudo modprobe -r nvidia_drm ; sudo modprobe -r nvidia_modeset ; sudo modprobe -r nvidia_uvm ; sudo modprobe -r nvidia # keep running this until modprobe doesn't complain about anyting being loaded)
sudo tee /proc/acpi/bbswitch <<< OFF
sudo pacman -R xf86-input-mouse
sudo systemctl start gdm

If you're wondering why you need to uninstall xf86-input-mouse:

[ 2437.363642] [DEBUG][XORG] (**) <default pointer>: always reports core events
[ 2437.363645] [DEBUG][XORG] /usr/bin/X: symbol lookup error: /usr/lib/xorg/modules/input/mouse_drv.so: undefined symbol: xf86GetOS
[ 2437.373896] [DEBUG]Process with PID 29061 returned code 127
[ 2437.373913] [ERROR]X did not start properly
I'm running with the following packages installed:
bumblebee-git bbswitch-dkms-git acpi_call-dkms nvidia-dkms

Hopefully something I posted can get you up and running again.

Likely a similar cause and issue as: https://bbs.archlinux.org/viewtopic.php?id=237045

so It is not bumblebee related but nvidia/xorg related?

Re: after newset updates (recently ) sddm blank screen

I downgraded xorg-server to 1.19(last version before 1.20) and it fixed it (I had to restart lightdm after reboot, but it worked.)

UPDATE:
it seems that even with downgraded xorg-server sddm has the same issue as before.

so I upgraded the xorg-server to 1.20 again and used lightdm and it works with some caveats. First , I have to restart bumblebeed service after reboot. 2nd the graphical login is started on tty7 not tty1.
