Since PureOS is based on Debian buster, the versions of kwayland and kwin I was running were: kwayland 5.42.0-2 kwin 5.12.1-1 Using the patches attached to T8067... 1. I built and installed a kwayland 5.42.0-3 and kwin 5.12.1-2 from the debian sources + the patches 2. rebooted for good measure 3. I uncommented the 'export QT_QPA_PLATFORM=wayland' line in the plasma-phone script (so that it is back to the original version with no changes) 4. Started kwin_wayland with: $ kwin_wayland --drm plasma-phone I can confirm that the patches remove the bad display issue and the display looks great!! When will the Plasma 5.13 release be ready? I can carry them in a fork but I'd like to be working ideally off of packages included in Debian, or at least the patched kwin and kwayland repos. > >>> * Do you know how to make the mouse cursor show up? > > There is two bugs, and workaround: > > - https://bugs.kde.org/show_bug.cgi?id=391412 : due to this, if hardware > doesn't provide the cursor plane it never fallbacks to software > cursor. > - However, this is more interesting > - KWin calls : output->initCursor(m_cursorSize) > - initCursor calls DrmBuffer::map > - But somehow map function is failing internally, but returns true > anyway. > - Through gdb session if we break on DrmOutput::initCursor() and > make it return false early, it initalizes the software cursor > correctly. > - Which makes me believe either there is something wrong in > DrmBuffer::map and/or the DRM driver. > > The solution is to ofcourse fix a bug.. but other then that, as a > workaround you can enable track mouse effect and press Ctrl+Meta to make > it show a "circle" around mouse cursor position.
