Hyprland not displaying any windows

Zurite · 2024-01-19 03:41:28

In looking around for a solution to this problem I've found that most of the solutions involve some kind of remote server that people are messing up, but I'm not using anything like that.

When I use "echo $DISPLAY" I get nothing, and kitty isn't opening due to missing the environment variable.

I've tried all kinds of variables using export, but none of them seem to work when I try launching kitty. I'm also having issues with Hyprland not displaying or opening windows, but that might be totally unrelated for all I know. I'm mostly wondering what DISPLAY is supposed to be, and how I can fill it in.

How are you starting Hyprland?

If I run `Hyprland` from a TTY login DISPLAY is set correctly with no configuration needed.

V1del · 2024-01-19 09:27:31

It would and should be filled, is xorg-xwayland installed?

I'm doing the same thing.

I just installed it and it didn't seem to change anything, is there more setup that I need to do?.

V1del · 2024-01-19 15:26:32

restart hyprland after having it installed.

Zurite · 2024-01-19 15:45:37

I rebooted my system and started Hyprland. It looked exactly the same as before, with no windows opening when I press the key binds. After I closed it, however, I got a new error that didn't show up before.

[glfw error 65544]: Wayland: Failed to connect to display
GLFW initialization failed

Which is the same error that kitty has been throwing back at me.
Also, echo $DISPLAY still returns nothing.

seth · 2024-01-19 15:48:16

Can you "xdpyinfo -display :0" ?

Zurite · 2024-01-19 17:01:58

The command is not found.

Zurite · 2024-01-19 17:33:37

I installed xorg-xdpyinfo and reran the command.

It returned:
xdpyinfo: unable to open display ":0"

Head_on_a_Stick · 2024-01-19 18:20:19

FWIW I still get the correct DISPLAY value in Hyprland even without xorg-xwayland.

@OP: what is your graphics hardware?

lspci -k -d ::03xx

Zurite · 2024-01-19 18:39:04

00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07
Subsystem: ASUSTek Computer Inc. Mobile 4 Series Chipset Integrated Graphics Controller

Kernel modules: i915
00:02.1 Display controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07)
Subsystem ASUSTek Computer Inc. Mobile 4 Series Chipset Integrated Graphics Controller

For the record, I do know that I am using a computer from around 2006, and I really should have mentioned that earlier, but that still doesn't explain to me why DISPLAY is missing.

Edit: I also wanted to mention that when I boot up hyprland I do get a cursor, so something is rendering even without the DISPLAY variable.

Going back to the OP:

How are you using `echo $DISPLAY` if kitty won't open? How do you know that kitty is failing "due to missing the environment variable"?

Sorry if this is too obvious - but you're sure that's not just the tty? Rather than `echo $DISPLAY`, what do you get from just entering `tty`?

Also, while the suspicion I'm getting at above is the most relevant, DISPLAY is specifically an X11 thing. If a compositor is using Xwayland, there should be a DISPLAY variable, but otherwise there would not be, though there would be a WAYLAND_DISPLAY variable. Do you have this variable set (e.g., `echo $WAYLAND_DISPLAY`)?

Zurite (from OP) wrote:

I'm also having issues with Hyprland not displaying or opening windows

That almost certainly is relevant. What windows are not opening? E.g., which ones would you expect to see?

I'm sorry, but I'm not really knowledgeable enough in this stuff to answer this question in a smart way. I'm not using kitty to do anything, I'm using whatever basic terminal you start with in arch. Since hyprland isn't working I don't have a window manager of any kind.

Trilby wrote:

It returns '/dev/tty1'
Also what I meant by cursor was my mouse cursor, not a text cursor. Sorry if I was misleading.

Trilby wrote:

This also returns nothing.

Trilby wrote:

When I run Hyprland I get a blank screen with my cursor on it. No windows open with any of the shortcuts set in the config. Honestly, at this point I think the issue is that any window it wants to open doesn't open because it can't find the display, since running any of these programs in the terminal tells me they can't find the display. SUPER+M does work to close Hyprland, but sometimes closing Hyprland gives me a blank screen that I can't interact with, forcing me to restart.

Trilby · 2024-01-19 19:45:09

So hyprland isn't even running - that is the problem that needs to be fixed.

Head_on_a_Stick · 2024-01-19 19:45:15

The "basic terminal" is called a TTY or console and it's not supposed to have DISPLAY set. Your thread title & OP are an XY-problem, which I should have picked up on sooner. Sorry about that.

The actual problem here is that you can't open kitty. Which keys are you using to attempt that, exactly?

Please also share the output of

grep '$terminal' ~/.config/hypr/hyprland.conf
pacman -Q kitty

EDIT: crossposted, Trilby is right. Ignore my request.

So you're saying that Hyprland is the issue and that the error kitty is giving me makes sense because it should only be able to run when there is a DISPLAY variable anyways? That makes a lot of sense actually, but I am somewhat confused as to how Hyprland is broken. I haven't gotten any kind of error messages from anything relating to it.
Since the actual issue I have has nothing to do with the OP and title, do I need to make a new post? Sorry for leading you guys on a wild goose chase with this issue.

Head_on_a_Stick · 2024-01-19 19:59:06

Kitty can't be run from a TTY and it doesn't need DISPLAY to be set to work under Wayland.

Edit the title to reflect the actual problem and follow the suggestion in my second EDIT above.

No need to apologise, I should have picked up on this immediately. Props to Trilby for actually using their brain, unlike me.

I'm not really sure how to check the log, putting in the first command on that page prints out a pretty short log and I don't know how to use debug:disable_logs or debug:enable_stdout_logs.

Also, I'm not sure if that's the best name for the topic, so if anyone has any better ideas I'd be happy to change it again.

Also Also, since I'm doing everything in TTY I don't really have any way (that I know of) to copy and paste any of the log onto here to show you guys, just an FYI.

Here is the log, but it doesn't have much information and I'm not sure how to enable the debug option. I tried adding debug:enable_stdout_logs into the conf file, but that didn't seem to change anything.

Also, after closing Hyprland an error was written after my prompt

It reads:

EDIT:

By the way, I'm having the same issue with sway, where I'm pressing the keybinds to spawn windows and nothing spawns. Also, when I run sway I can see the toolbar, background and mouse, and I can switch workspaces. My guess would be that there's something wrong with Wayland, particularly in spawning/displaying windows. Hopefully this makes the issue clearer.

How about this outputs:

echo $DISPLAY
echo $XDG_CURRENT_DESKTOP
echo $WAYLAND_DISPLAY
env | grep -i wayland

Is wlroots installed ?
The problem of Mod+q Mod+m is not responding after logged in, thats some packages are missing. It happened to me too.

Just to be clear, you've started hyprland, figured the shortcuts don't work and then have tried to start stuff from a console either by switching the VT or terminating hyprland??

pacman -Qs kitty

post your hyprland.conf and can you autostart kitty w/ hyprland?

Zurite · 2024-01-20 15:14:54

My understanding of what's going on is that I've started Hyprland, figured that windows weren't opening and then tried to start stuff from TTY, which didn't work because there's not supposed to be any display variables set there. I'm almost certain that hyprland's shortcuts do actually work because I can quit it with SUPER+M. What I think it might be is some kind of rendering issue causing windows to not appear, probably with Wayland since using sway resulted in the same kind of issue where windows wont appear but the shortcuts for exiting and switching workspaces still work.

pacman -Qs kitty

returns:

local/kitty 0.31.0-1
