Flameshot: Flameshot not launching when using Wayland

[BlueskyFR]

Flameshot version
0.6.0-9(Debian)

Describe the bug
The commands flameshot gui or flameshot config doesn't do anything.

To Reproduce
I am using the sway (swaywm) window manager on Wayland.

Expected behavior
It should open properly.

System Information
Ubuntu 19.04

[vvrein]

Try run flameshot as QT_QPA_PLATFORM=wayland-egl flameshot
Also, try to install waybar, which support (partially) tray, so you can see wether flameshot is running

[vvrein]

Also, related to wayland based WM https://github.com/lupoDharkael/flameshot/issues/619
Currently, seems that flameshot does not support capturing screen under wayland.
So, even if you can run it, you can't do anything

You can make all your QT apps use XWayland:
export QT_QPA_PLATFORM=xcb
Add this to /etc/profile file, then restart.

[bwoodruff]

With Fedora 32 I can only get the Flameshot icon to appear in the tray if I start it using

QT_QPA_PLATFORM=xcb flameshot

[Tids]

Whats the point in starting flameshot in xwayland? You then can only screen up xorg apps, not pure wayland stuff.

[BlueskyFR]

@Tids we should be able to.

[joaoeudes7]

export QT_QPA_PLATFORM=xcb flameshot

This works, but this isn't possible set in installation?

[mmahmoudian]

@ZetaoYang is this still a valid issue considering the recent changes?

[joaoeudes7]

Yeah, I use ArchLinux, I believe it is with the latest versions and it is not working yet

[mmahmoudian]

@joaoeudes7 I probably know what is happening. the same thing happens with the current flameshot-git AUR. When you run flameshot gui or any other argument of flameshot, the main application does not get launched. To bypass this while we are investigating this follow:

https://github.com/flameshot-org/flameshot/issues/790#issuecomment-687416350

This is something that has been reported numerous times and perhaps @ZetaoYang or @borgmanJeremy have some idea on how to address this.

[pengux]

@mmahmoudian So I tried ( flameshot & ) && flameshot gui and it launched flameshot, but it just show the notification Unable to capture screen whenever I try to take a screenshot. I'm using Sway and Arch Linux

[mmahmoudian]

@pengux I'm so confused, it opened but throw an error? can you post a screenshot (or take a photo with your phone)?

[pengux]

Yes, here's a screenshot. Is there a debug flag to get debug logs when launching flameshot?

[vvrein]

@mmahmoudian here some logs for @pengux screenshot:

| QT_QPA_PLATFORM=wayland flameshot
qt.qpa.wayland: Wayland does not support QWindow::requestActivate()
qt.qpa.wayland: Wayland does not support QWindow::requestActivate()
qt.qpa.wayland: Wayland does not support QWindow::requestActivate()

1) I started flameshot from cli on sway
2) Flameshot icon appeared in the tray
3) On click on flameshot tray icon - I got same notifications as above
(actually I clicked 3 times, so there is 3 messages in terminal)

WM: sway
OS: Arch Linux
| flameshot -v
Flameshot v0.8.0
Compiled with Qt 5.15.0

[ZetaoYang]

@mmahmoudian I confirm this is a bug, when I used flameshot on Fedora 32 Gnome with Wayland, this issue appears.But on Fedora 31 with Wayland, it can start normally .

[borgmanJeremy]

I can confirm this with sway on arch. Thanks for clarifying, It seems to work okay with KDE on Wayland.

Edit: I intend to look into this, just want to confirm it took a very specific setup to create.

[joaoeudes7]

Using package flameshort-git works, but flameshort not.

Thank you for your attention and commitment to the project

[mmahmoudian]

@DjinNO Please report the Flameshot version (or the commit you built if from) and format (in case you use AppImage or Flatpak)

[DjinNO]

@mmahmoudian Now i'm using v0.8.0 from AUR

[pavel-the-best]

The bug is still present on master

[mystiquewolf]

Ubuntu 20.04 - GNOME 3.36.4 - Wayland - Flameshot 0.8.1
It was working before with the old 0.6.0 repo version from Ubuntu

[mystiquewolf]

Excuse me, the version in Ubuntu Software is listed as 0.8.3, but in "About" it is said to be 0.8.1.

[borgmanJeremy]

@mystiquewolf can you open a seperate issue for the version number mismatch so I don't clutter this one with questions?

[mng-25]

Flameshot 0.8.5, compiled with Qt 5.15.1, from AUR flameshot-git with debug and !strip options on the following system:

Operating System: Arch Linux
KDE Plasma Version: 5.20.0
KDE Frameworks Version: 5.75.0
Qt Version: 5.15.1
Kernel Version: 5.8.14-arch1-1
OS Type: 64-bit
Processors: 8 × Intel® Core™ i5-8250U CPU @ 1.60GHz
Memory: 7.5 GiB of RAM
Graphics Processor: Mesa Intel® UHD Graphics 620

on Wayland, i can get the config and about pages, as well as the launcher, but I cannot use the overlay ($ flameshot gui ) nor can I use the launcher. gdb states the following when I attempt to take a full screenshot from the launcher (region causes the window to flicker and I hover over the screenshot button for a few seconds):

$ gdb -ex=r /usr/bin/flameshot

Annoyingly, I use screenshots infrequently enough that I can't be certain when this last worked.
