# MODULES
# The following modules are loaded before any boot hooks are
# run.  Advanced users may wish to specify all system modules
# in this array.  For instance:
#     MODULES=(piix ide_disk reiserfs)
MODULES="nvidia nvidia_modeset nvidia_uvm nvidia_drm"

# BINARIES
# This setting includes any additional binaries a given user may
# wish into the CPIO image.  This is run last, so it may be used to
# override the actual binaries included by a given hook
# BINARIES are dependency parsed, so you may safely ignore libraries
BINARIES=()

# FILES
# This setting is similar to BINARIES above, however, files are added
# as-is and are not parsed in any way.  This is useful for config files.
FILES=""

# HOOKS
# This is the most important setting in this file.  The HOOKS control the
# modules and scripts added to the image, and what happens at boot time.
# Order is important, and it is recommended that you do not change the
# order in which HOOKS are added.  Run 'mkinitcpio -H <hook name>' for
# help on a given hook.
# 'base' is _required_ unless you know precisely what you are doing.
# 'udev' is _required_ in order to automatically load modules
# 'filesystems' is _required_ unless you specify your fs modules in MODULES
# Examples:
##   This setup specifies all modules in the MODULES setting above.
##   No raid, lvm2, or encrypted root is needed.
#    HOOKS=(base)
#
##   This setup will autodetect all modules for your system and should
##   work as a sane default
#    HOOKS=(base udev autodetect block filesystems)
#
##   This setup will generate a 'full' image which supports most systems.
##   No autodetection is done.
#    HOOKS=(base udev block filesystems)
#
##   This setup assembles a pata mdadm array with an encrypted root FS.
##   Note: See 'mkinitcpio -H mdadm' for more information on raid devices.
#    HOOKS=(base udev block mdadm encrypt filesystems)
#
##   This setup loads an lvm2 volume group on a usb device.
#    HOOKS=(base udev block lvm2 filesystems)
#
##   NOTE: If you have /usr on a separate partition, you MUST include the
#    usr, fsck and shutdown hooks.
HOOKS="base udev autodetect modconf block keyboard keymap consolefont filesystems fsck"

# COMPRESSION
# Use this to compress the initramfs image. By default, gzip compression
# is used. Use 'cat' to create an uncompressed image.

#COMPRESSION="xz"

I think you need to add

GRUB_CMDLINE_LINUX="nvidia-drm.modeset=1"

then run
sudo update-grub

Again, not quite sure, but you missed the plasma-wayland-protocols package too, and reboot after that.

Last time i tested on another install, was “working” but not quite usable for some tasks, and IMO is not there yet for daily usage.

Thenujan · 16 March 2022 08:28

tried both didn’t work it reacts the same way.

you mean wayland on nvidia or simply just wayland?

anon89812132 · 16 March 2022 08:36

Wayland with Nvidia in KDE Plasma …
You might want to check also the sddm configs … Options like

[X11]
ServerArguments=-dpi 0

for example, should not be there i guess under /etc/sddm.conf.d/kde_settings.conf

Also, some installs seem to have a particular 00manjaro conf or something … not sure if needed tho.

Then there should be EnableHiDPI=true under /etc/sddm.conf for both X11 and Wayland.

Will take a closer look at my other install, later this evening, and see if i can still log in with wayland session.

Thenujan · 16 March 2022 08:50

It isnt there.

both were set to false but changing them to true didnt fix it

anon89812132 · 16 March 2022 09:18

Don’t know, will check more later, as this are just “surface” observations i had … Also, after a quick look, the other install has also wrapland and python-pywayland packages installed and the ~/.config/kwinrc on the install that i’m able to log in wayland sessions does not have the Backend=OpenGL in the [Compositing] options.
Anyway, hope someone else will pass by with more solid information.

rvc · 16 March 2022 09:26

did you try to go to another tty [ Ctrl+Alt+F2/F3/F4 etc] and try running executing “startplasma-wayland” ? perhaps you can get some verbose on whats wrong

Thenujan · 16 March 2022 09:45

it showed no backend specified through command line argument
which led to
https://bbs.archlinux.org/viewtopic.php?id=255447

setting KWIN_COMPOSE=0
does make walynd session work but its not a great experience . cursor is glitching and sometimes the frame rate is very low.
btw i can only start it from command line .
Maybe i can set that as an environment variable and be able to use wayland without commandline.

JiaZhang · 17 March 2022 02:51

I heard that NVIDIA driver didn’t play well with Wayland. I never try Wayland before, so I can’t tell much.
