Dear Maintainer,

Hello,

I have started to use sway as my primary window manager unfortunately
krita does not work with wayland it seems. Other Qt applications seems
to work just find (provided I set the right environment variable ie
QT_QPA_PLATFORM=wayland)

Here's the log:

    qt.qpa.xcb: could not connect to display :0
    qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
    This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

    Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, wayland-egl, wayland, wayland-xcomposite-egl, wayland-xcomposite-glx, xcb.


I tried running "krita --platform wayland" without success.

Here's also the result of "QT_DEBUG_PLUGINS=1 krita" (which shows that
the wayland plugins should be available I think)

thanks

Hi,

In data sabato 4 aprile 2020 11:22:08 CET, Nicolas Évrard ha scritto:

krita has never supported Wayland so far. It uses various X technologies
(e.g. tablet support, color management) that are not available under
Wayland, or nobody worked on them in krita.

There is an upstream bug mentioning this:
https://bugs.kde.org/show_bug.cgi?id=429079
starting from the upcoming version 4.4.2, you will even get an error
message with krita closing itself afterwards in case you are running
under Wayland. Please run krita within XWayland until proper Wayland
support is implemented in krita.

Thanks,

We believe that the bug you reported is fixed in the latest version of
krita, which is due to be installed in the Debian FTP archive.

A summary of the changes between this version and the previous one is
attached.

Thank you for reporting the bug, which will now be closed.  If you
have further comments please address them to 955730@bugs.debian.org,
and the maintainer will reopen the bug report if appropriate.

Closes: 955730
Changes:
 krita (1:6.0.0~beta2+dfsg-1) experimental; urgency=medium
 .
   * New upstream development release:
     - supports Wayland (Closes: #955730)
   * Switch watch file to the unstable releases.
   * Switch Vcs-* fields to the 'experimental' packaging branch.
   * Update the build dependencies following the port to Qt 6:
     - remove libkf5completion-dev, libkf5config-dev, libkf5coreaddons-dev,
       libkf5crash-dev, libkf5guiaddons-dev, libkf5i18n-dev, libkf5itemviews-dev,
       libkf5kdcraw-dev, libkf5widgetsaddons-dev, libkf5windowsystem-dev,
       libpoppler-qt5-dev, libqt5opengl5-dev, libqt5svg5-dev,
       libqt5x11extras5-dev, libquazip1-qt5-dev, pyqt5-dev, python3-pyqt5,
       qtbase5-dev, qtbase5-private-dev, and qtdeclarative5-dev
     - temporarily remove libkseexpr-dev, as the Qt 6 version is not available
       yet
     - add libkdcrawqt6-dev, libkf6colorscheme-dev, libkf6completion-dev,
       libkf6config-dev, libkf6coreaddons-dev, libkf6crash-dev,
       libkf6guiaddons-dev, libkf6i18n-dev,  libkf6itemviews-dev,
       libkf6widgetsaddons-dev, libpoppler-qt6-dev, libquazip1-qt6-dev,
       pyqt6-dev, python3-pyqt6, python3-sipbuild, qt6-5compat-dev, qt6-base-dev,
       qt6-base-private-dev, qt6-declarative-dev, qt6-svg-dev, qt6-wayland-dev,
       and qt6-wayland-private-dev
   * Update the other build dependencies according to the upstream build system:
     - bump cmake to 3.19.0
     - bump extra-cmake-modules to 6.0
     - bump libopencolorio-dev to 2.0.0
   * Modernize building and update it to KF6:
     - add the dh-sequence-kf6 build dependency to use the kf6 addon
       automatically
     - drop the pkg-kde-tools build dependency, no more explicitly needed
     - drop all the manually specified addons and buildsystem for dh
   * Pass -DBUILD_WITH_QT6=ON to cmake to explicitly build using Qt 6.
   * Update the runtime relationships to Qt 6:
     - switch libqt5sql5-sqlite to libqt6sql6-sqlite
     - switch python3-pyqt5 to python3-pyqt6
     - switch qml-module-qtmultimedia to qml6-module-qtmultimedia
   * Update the patches:
     - upstream_Bump-SIP-ABI-version-to-12.8.patch: drop, fixed upstream
   * Stop adding -Wno-template-id-cdtor to the CXXFLAGS, as the warnings were
     fixed.
   * Append -Wno-deprecated -Wno-deprecated-declarations to the CXXFLAGS,
     as there are lots of deprecation warnings that make build logs bigger.
   * Update install files.
   * Add maintscript to remove the old /etc/xdg/kritarc conffile.
