 Posted: Tue Sep 07, 2021 6:30 am Post subject: how to add custom screen resolution in wayland? |
 |
|
i use xorg before and now i am trying wayland.
i added wayland to USE in make.conf and run emerge. After that i can enter kde plasma with
XDG_SESSION_TYPE=wayland dbus-run-session startplasma-wayland
However, my screen resolution is default to 1024*768 now, the 1920*1080 won't appear in the dropdown list.
I used to add custom resolution with xrandr, but xrandr does not work for wayland.
I think the "kanshi" might work. but "kanshi" returns the following message:
"compositor doesn't support wlr-output-management-unstable-v1"
And if i try to run xorg with startx as before, the mouse and keyboard won't response after entering kde plasma
[url] https://pastebin.com/HKUj5kJc [/url] is the xorg.0.log
and what follows is the make.conf
| Code: | # These settings were set by the catalyst build script that automatically
# built this stage.
# Please consult /usr/share/portage/config/make.conf.example for a more
# detailed example.
COMMON_FLAGS="-O2 -pipe -fno-omit-frame-pointer"

IIRC monitor resolution isn't to be set at wayland level, but window manager, e.g. sway, wayfire, gnome, kde, etc...
[EDIT] | Code: | XDG_SESSION_TYPE=wayland dbus-run-session startplasma-wayland
Launching kwin
kwin_wayland: symbol lookup error: kwin_wayland: undefined symbol: _ZNK20QPlatformIntegration28createPlatformVulkanInstanceEP15QVulkanInstance, version Qt_5_PRIVATE_API
Kwin exited with code 127
startplasmacompositor: Shutting down...
startplasmacompositor: Done |
both from console & terminal.
Not ready here to help you any further.

No, xrandr doesn't work in wayland ... use wlr-randr, although wdisplays is a better alternative, with visual layout, though it doesn't seem to have an ebuild.
proper call for dbus is
| Code: | | dbus-run-session -- startplasma-wayland |
set your vars ahead of calling wayland,
XDG_SESSION_TYPE=wayland
you may need one or more of these
QT_QPA_PLATFORM=wayland
QT_QPA_PLATFORMTHEME=qt5ct ----- if you use qt5ct for setting desktop look
several other QT_* vars but they're not normally needed
you also need XDG_RUNTIME_DIR set (should be automatically set)

Guru repo has wdisplays as well as wlr-randr, and some other interesting wayland pkgs.

I just emerged wlr-randr as you suggest, however, it prompt the same error message as kanshi
| Code: |
gym@gymDeskGentoo ~ $ wlr-randr
compositor doesn't support wlr-output-management-unstable-v1 |
And wdisplays give the same message.
in htop, i can see process name such as startplasma-wayland , kwin_wayland, Xwayland. |

Since you're on plasma, try kscreen

maybe i should try adding a drm.edid_firmware kernel parameter.
but i am using efibootmgr instead of grub. how to add this kernel parameter? are there any way to just append this parameter instead of deleting the existing efibootmgr entry and creating a new one? i don't even remember the command line to create a new efibootmgr entry!
maybe i could try "set CONFIG_CMDLINE_BOOL=y and then set CONFIG_CMDLINE" : https://stackoverflow.com/questions/22035110/passing-parameter-to-builtin-kernel-module-at-compile-time
i would rather recompile the kernel than touch those efibootmgr entry. |

What monitor is it? name, model, etc
How did you get X to work without the edid?
If it can't see the edid then, it doesn't know how make the monitor work with more than standard vesa modes.
