[SDDM] Touchpad tap to select
MERGE REQUEST
Full discussion at https://github.com/prasanthrangan/hyprdots/issues/1081
For laptop/touchpad users:
- tap to select an option
Here's the list added to the xorg.conf.d/
Section "InputClass"
Identifier "libinput touchpad catchall"
MatchIsTouchpad "on"
MatchDevicePath "/dev/input/event*"
Driver "libinput"
Option "Tapping" "on"
Option "NaturalScrolling" "on"
Option "MiddleEmulation" "on"
Option "DisableWhileTyping" "on"
It looks good. I believe that libinput is already a dependency for something else in Hyprdots, so this should do it.
is this only valid for x11?? what if you set it to wayland, will this be necessary??
@prasanthrangan
Yes it's only valid for X11 For wayland there's a different way to solve it. I haven't done enough reading on it to know exactly how to solve for wayland.
This issue was brought up in sddm repo here. Apparently it's the wayland compositor that is supposed to deal with it.
Trying wayland, the touchpad tap to select is not enable by default. Can't find anything to enable it
[General]
DisplayServer=wayland-user
GreeterEnvironment=QT_WAYLAND_SHELL_INTEGRATION=layer-shell
[Wayland]
CompositorCommand=Hyprland
[!Important] This layer shell is included in layer-shell-qt and layer-shell-qt5. The latter package is needed until SDDM drops Qt5, otherwise you will get a black screen. [6]
https://github.com/hyprwm/Hyprland/issues/820 To be able to use sddm on wayland we needed a wayland compositor. Hyprland do not yet support this https://github.com/hyprwm/Hyprland/issues/820.
Unfortunately even if Hyprland by default has tap-to-click by default it did not work.
UPDATE:
[Wayland] CompositorCommand=Hyprland
This part is useless
@kRHYME7 There are 2 compositors:
- Hyprland: It does not run until sddm tells it to. Therefore it cannot be the compositor managing sddm.
- Weston: I believe is the compositor that is running before sddm and manages sddm.
I found this out when I clicked on the WM selector on sddm.
By default DisplayServer=wayland attempts to use weston, even if it's not installed, to use a different Wayland compositor, enter the program and relevant arguments to the CompositorCommand option as described in SDDM#KDE / KWin, see also sddm.conf(5) for more.
- Yeah I think Hyprland soon would have it's own DM so this won't be posible
- We should find an option for weston to have tap-to-click.
Tested weston, tap to click is enabled by default. But I don't think
Maybe my configuration is wrong ?
[General]
DisplayServer=wayland-user
GreeterEnvironment=QT_WAYLAND_SHELL_INTEGRATION=layer-shell
[Wayland]
CompositorCommand=weston
One more
Can we add some kde settings, should sddm respects that?
Wayland Solution FOUND
EDIT: I had put in the wrong sddm.conf EDIT 2: wrong one again. (I just can't copy to clipboard from nvim)
I used weston as the compositor. It is the default wayland compositor set in sddm.
All I had to do is add /etc/xdg/weston/weston.ini and then populated it with the following contents found at this arch wiki on weston

TLDR
Basically, the only change I made is add /etc/xdg/weston/weston.ini and then changed the DisplayServer option in sddm from DisplayServer=x11 to DisplayServer=wayland
Cool! Only problem we might face is if weston is not present by default How did you get your weston? i have 2 machines, my other one do not have weston.
paru -Qi weston
Also, should it be fine if we added weston as dependency so that we can composite sddm on wayland?
@kRHYME7 I didn't install weston myself. I think it's a dependency of something in Hyprdots. Lemme setup a VM to see if it's installed by Hyprdots.
Try to run pacman -Qi weston maybe it give you lead to why this is installed

same here, weston is not installed by default... but for some reason setting sddm DisplayServer to wayland still works.... which is strange.....

Maybe on fallback mode? Or hyprland now can manage sddm layer?
@sandeng1440 Hi!
This time we can manage to render sddm on Hyprland
see comments below https://github.com/hyprwm/Hyprland/issues/820
The only issue we might get is sddm only renders on a single monitor. Can be solved if we mirror them with some caveats
Will be Adding the config in this discussion for now, someone might refactor/refine it.
@kRHYME7 I've read the comments and I understand that hyprland desktop appears first, followed by sddm. Isn't this behavior a problem?

Well, not really. The only issue I can think of is we will have 2 Hyprland sessions. 1 is for sddm (after login, sddm will be the parent session) and 1 for the User. Which roughly consumes around 240 mb of memory for sddm. I do not know how much memory weston/cage will consume when running sddm though.
@sandeng1440 I'm totally wrong. Only a single Hyprland instance is active after loging in from sddm using hyprland.
Only Issue I got is when I plug in a monitor, sddm will create a new window then now we have 2 windows inside a single monitor instead of this windows should be on the new monitor. Can be solved with scripting and IPC.
Sorry for being too enthusiastic with using hyprland as compositor for sddm lol.
@kRHYME7 no worries. This seems to be a harder issue than I first thought.
