--- Comment #24 from aiamuzz <muzafsh....@gmail.com> ---
apologies for trying to be self reliant ... I am the only one facing this
issues it seems ... so trying to help myself ...
could these be the possible file that needs the corrected code ?
kwin-v5.15.5/plugins/platforms/drm/drm_output.cpp
relevant parts ???
**************
namespace {
quint64 refreshRateForMode(_drmModeModeInfo *m)
{
// Calculate higher precision (mHz) refresh rate
// logic based on Weston, see compositor-drm.c
quint64 refreshRate = (m->clock * 1000000LL / m->htotal + m->vtotal / 2) /
m->vtotal;
if (m->flags & DRM_MODE_FLAG_INTERLACE) {
refreshRate *= 2;
}
if (m->flags & DRM_MODE_FLAG_DBLSCAN) {
refreshRate /= 2;
}
if (m->vscan > 1) {
refreshRate /= m->vscan;
}
return refreshRate;
}
}
**************
// read in mode information
QVector<KWayland::Server::OutputDeviceInterface::Mode> modes;
for (int i = 0; i < connector->count_modes; ++i) {
// TODO: in AMS here we could read and store for later every mode's
blob_id
// would simplify isCurrentMode(..) and presentAtomically(..) in case
of mode set
auto *m = &connector->modes[i];
KWayland::Server::OutputDeviceInterface::ModeFlags deviceflags;
if (isCurrentMode(m)) {
deviceflags |=
KWayland::Server::OutputDeviceInterface::ModeFlag::Current;
}
if (m->type & DRM_MODE_TYPE_PREFERRED) {
deviceflags |=
KWayland::Server::OutputDeviceInterface::ModeFlag::Preferred;
}
KWayland::Server::OutputDeviceInterface::Mode mode;
mode.id = i;
mode.size = QSize(m->hdisplay, m->vdisplay);
mode.flags = deviceflags;
mode.refreshRate = refreshRateForMode(m);
modes << mode;
