If CopyQ is running, you can run copyq show to show the main window.

Looks like CopyQ cannot access clipboard for some reason -- or more specifically mouse selection. It seems you are running Wayland (as opposed to X11) and I thought it doesn't support selection.

You can try disabling all options under "Clipboard Manipulation" except "Store Clipboard" in CopyQ configuration:

That is unfortunately not working neither.

Oh, sorry, I pasted wrong screenshot. The configuration to avoid checking mouse selection should be like this:

@rgarcia89 Can you please check again?

Doesn't work neither. It is also not able to set the shortcuts like you can see here

hluk commented 5 years ago

Setting global shortcuts in Wayland is not supported (not sure if they already have a generic API for it).

rgarcia89 commented 5 years ago

So this means that nothing of copyq is currently usable under fedora 31 and wayland... Thats really bad 🙈

hluk commented 5 years ago

So this means that nothing of copyq is currently usable under fedora 31 and wayland... Thats really bad see_no_evil

I'm going to update to F31 soon and see if Wayland is finally usable for me. I'll try to fix these issues while I'm at it. :)

hluk commented 5 years ago

OK, I've upgraded to F31.

Looks like it's not possible to access clipboard with Qt unless the window requesting the access is focused.

This is also somewhat related: Custom notifications (a "tooltip" window) gets focused when they pop up and it doesn't seem to be possible to show them without focus (I messed around with window attributes). Couple of other Qt applications are broken because they use some special window behaviors (e.g. smplayer cannot embed video player window, konsole doesn't show menus).

It could be a bug in Gnome.

Below is short snippet to test the clipboard access (uses PyQt5). If you click "Update" button it gets formats currently in clipboard. Clicking "Get" gets the selected format. You can select the format in combo box, but opening the combo list somehow breaks clipboard access so Get and Update buttons no longer work unless the window is deactivated and activated again.

#!/usr/bin/env python3
import sys

from PyQt5 import QtCore
from PyQt5 import QtGui
from PyQt5 import QtWidgets

app = QtWidgets.QApplication(sys.argv)

def update_format_list(combo):
    combo.clear()
    data = app.clipboard().mimeData()
    for mime in data.formats():
        combo.addItem(mime)

def get_format(combo, label):
    mime = combo.currentText()
    data = app.clipboard().mimeData().data(mime)
    if mime.startswith('image'):
        image = QtGui.QImage.fromData(data)
        pixmap = QtGui.QPixmap.fromImage(image)
        label.setPixmap(pixmap)
    else:
        text = data.data().decode()
        label.setText(text)

combo = QtWidgets.QComboBox()
update_format_list(combo)

label = QtWidgets.QLabel()
label.setAlignment(QtCore.Qt.AlignCenter)

get_button = QtWidgets.QPushButton('&Get')
get_button.clicked.connect(lambda: get_format(combo, label))

update_button = QtWidgets.QPushButton('&Update')
update_button.clicked.connect(lambda: update_format_list(combo))

hlayout = QtWidgets.QHBoxLayout()
hlayout.addWidget(combo, stretch=1)
hlayout.addWidget(get_button)
hlayout.addWidget(update_button)

vlayout = QtWidgets.QVBoxLayout()
vlayout.addLayout(hlayout)
vlayout.addWidget(label)

window = QtWidgets.QWidget()
window.setLayout(vlayout)

window.show()
app.exec_()

Workaround is to set QT_QPA_PLATFORM environment variable and use Xwayland (xorg-x11-server-Xwayland fedora package) to handle X11 apps.

E.g. launch CopyQ with:

env QT_QPA_PLATFORM=xcb copyq

If CopyQ autostarts, you can change Exec=... line in ~/.config/autostart/copyq.desktop:

Exec=env QT_QPA_PLATFORM=xcb copyq
rgarcia89 commented 5 years ago

@hluk this way copied text is stored in copyq. The only thing not working right now is storing text selected by the mouse. Thanks figuring out that workaround

hluk commented 5 years ago

The only thing not working right now is storing text selected by the mouse.

@rgarcia89 Mouse selections should work only from other X11 apps. AFAIK, Wayland doesn't support them.

Spacewalker2 commented 3 years ago

I use Arch Linux with Sway. After the last update all the above described behavior happens here too now.

hhlp commented 3 years ago

if I launch in this way works:

E.g. launch CopyQ with:

env QT_QPA_PLATFORM=xcb copyq

if I add in desktop file doesn't works

Exec=env QT_QPA_PLATFORM=xcb copyq

fedora 33 any clue?

Regards.,

hluk commented 3 years ago

For Fedora (32 and 33), there is development package with much better Wayland support.

You can install the package using:

sudo dnf install 'dnf-command(copr)'
sudo dnf copr enable lholecek/copyq
sudo dnf install copyq
tigerjack commented 3 years ago

For Archlinux, the copyq-git package in the AUR works as expected.

123swk123 commented 1 year ago

assuming you installed to defrault system path

for different path

Same here, found out it happens to the Flatpak version (7.0.0) I installed. Just nothing showing up in the clipboard when you try to copy things, nothing gets added.

hluk commented 1 year ago

I believe that the normal clipboard access does not work in Gnome Wayland session. It would need to be implemented somehow using Gnome Shell extensions.

You can verify if the clipboard access works with wl-paste CLI (on Fedora 38 it is part of wl-clipboard package).

Same here, found out it happens to the Flatpak version (7.0.0) I installed.

If you have this problem only with Flatpak version, it is possible that some arguments/permissions are missing in the specification:

I could not reproduce the problem, but I've only tested it in Sway.

Me too, I'm having the same problem, the solution would be to switch to X11 instead of Wayland, but I don' t know if that can affect any other functionality in my pc

buergi commented 6 months ago

Same for me. I guess it must be a mere configuration issue, otherwise I couldn't understand how this issue is still unsolved after almost 5 years, as it prevents the software from achieving its sole purpose on modern linux distributions. In the search of other tools I found others having the same issue e.g. here (in German) with the final verdict "Failed; on to the next tool."

CopyQ supports clipboard management in Wayland via some standard protocol, but (as mentioned before) Gnome Wayland session allows clipboard managers to be implemented only as Gnome Shell Extensions. From a security perspective, it makes sense ...although any other app that has focus can access the clipboard.

I believe, the workaround is to start CopyQ under XWayland with the following command (if it is supported in your Gnome installation):

env QT_QPA_PLATFORM=xcb copyq

Note: I still use Sway (or KDE occasionally) without any issue, so I don't have a reason to investigate further and fix this myself currently.

acosonic commented 1 month ago

I do try this on Ubuntu 24.04.1 but when I change some setting in app itself, it overwrites my changes...

Workaround is to set QT_QPA_PLATFORM environment variable and use Xwayland (xorg-x11-server-Xwayland fedora package) to handle X11 apps.

E.g. launch CopyQ with:

env QT_QPA_PLATFORM=xcb copyq

But strangely enough, it fails the other way around too: I have a well-filled history, but choosing an item won't copy it to my active window.

TiedSnake commented 1 month ago

For whoever is having this issue from the future here's what I found: cause of issue: copyq is having a problem with the wayland window manager which is shown in copyq's logs when opening copyq select this tab (Help>Show Log) the issue & the detailed solution mentioned in here

[Solution]: You want to start copyq using x11 window manager instead of wayland to achieve this use this command

Exec=env QT_QPA_PLATFORM=xcb copyq

before you launch it you may want to kill the previous process first using this command pkill copyq

keep in mind that launching copyq using the command above only works for the current instance so to have it always get launched using x11 you want to type the command above in the .desktop file for the app. Its name can be something like this com.github.hluk.copyq.desktop or this copyq.desktop The desktop file can be found in a directory depending on how you installed it

[LOCAL_USER_SCOPE]

[SYSTEM_SCOPE]

change the default execution command Exec= copyq --start-server show by including the command above Exec=env QT_QPA_PLATFORM=xcb copyq --start-server show

[Autostart] if you want to add the app to the autostart list you can copy the desktop file above to the autostart directory example: cp /usr/share/applications/<name_of_copyq_desktop_file> ~/.config/autostart/

To verify that the solution worked:

  1. Log out and then login again
  2. Check if Copyq starts automatically
  3. Copy anything & check copyq if it includes the recently copied item into the clipboard.
