Lower resolution (960x540) on video-hybrid-intel-nvidia-390xx-bumblebee

uninstall the bumblebee drivers:
mhwd -r pci video-hybrid-intel-nvidia-390xx-bumblebee
then provide output from:
pacman -Qs 'bbswitch|bumblebee|optimus|gpu'
pamac list -qm
mhwd-kernel -li

[manjaro /]#  pacman -Qs 'bbswitch|bumblebee|optimus|gpu'

[manjaro /]#  mhwd-kernel -li
Currently running: 5.15.60-1-MANJARO (linux515)
The following kernels are installed in your system:
   * linux515
   * linux515-rt
[manjaro /]# 

remove these:

pamac remove manjaro-documentation-en manjaro-firmware

these packages are dropped, you dont need them…


also remove the linux515-rt kernel if you are not needing it:
pamac remove linux515-rt


now post output again from this, to remove the leftover configs:
find /etc/X11/ -name "*.conf"
ls /etc/modprobe.d

and no need to create new post for every output, put them all in one

ok, so install linux510 as a backup kernel:
pamac install linux510
and install video drivers, for now without nvidia:
mhwd -i pci video-linux
mhwd -i pci video-modesetting
exit chroot:
exit
reboot and see if the resolution is correct and you have no issues you mentioned above

Not correct resolution… and Plasma not working, I cannot see Plasma taskbar.

Again with chroot.

Any comments?

and was it working normally before?

Since tuesday… yes…I had bumblebee running ok, and I installed prime switch, since that, became the disaster.

do you still have it installed?
pacman -Qs 'prime|switch'

[manjaro /]#  pacman -Qs 'prime|switch'
local/usb_modeswitch 2.6.1-3
    Activating switchable USB devices on Linux.
[manjaro /]# 

Also, in normal mode, I have autologin. I create another user, but, without path, it was on the konsole.

May be desktop will fix entering with another user?

so its no longer there…
thats a good idea, to create a new user… can you open system settings when you boot back into your installation?

No. I haven’t taskbar or quick access or anything.

Neither access to konsole.

and the mouse cursor is working? right click on deskop shows the menu?

Yes, mouse is working. Righ click don’t work.
