I've done a little digging; firstly I think it's the same as:
https://bugs.kde.org/show_bug.cgi?id=368494 (to which I commented
although it's closed because it went away when the reporter updated
their X server)
and
https://bugzilla.redhat.com/show_bug.cgi?id=1477592
and possibly
https://bugzilla.redhat.com/show_bug.cgi?id=1406752
I added a little debug to libkf5screen
#0 XRandRScreen::toKScreenScreen (this=0x559dd8b68980) at
./backends/xrandr/xrandrscreen.cpp:68
screenResources = {d = 0x0}
kscreenScreen = {value = 0x559dd8b78a70, d = 0x559dd8b78b90}
#1 0x00007fe0e9b18aba in XRandRConfig::toKScreenConfig (this=<optimized out>)
at ./backends/xrandr/xrandrconfig.cpp:117
config = {value = 0x559dd8b7ea80, d = 0x559dd8b7eb30}
features = {i = 3}
kscreenOutputs = {d = 0x559dd8b74bb0}
#2 0x00007fe0e9b14c14 in XRandR::config (this=<optimized out>) at
./backends/xrandr/xrandr.cpp:205
No locals.
#3 0x0000559dd6d7fac6 in BackendDBusWrapper::setConfig (this=0x559dd8b69c10,
configMap=...)
at ./src/backendlauncher/backenddbuswrapper.cpp:87
config = {value = 0x559dd8b778c0, d = 0x559dd8b77be0}
obj = {d = 0x559dd8b7ea80, o = 0x559dd8b7eb30}
#4 0x0000559dd6d815ef in BackendAdaptor::setConfig (in0=..., this=<optimized
out>)
at ./obj-x86_64-linux-gnu/src/backendlauncher/backendadaptor.cpp:51
No locals.
and:
KScreen::ScreenPtr XRandRScreen::toKScreenScreen() const
{
KScreen::ScreenPtr kscreenScreen(new KScreen::Screen);
kscreenScreen->setId(m_id);
kscreenScreen->setMaxSize(m_maxSize);
kscreenScreen->setMinSize(m_minSize);
kscreenScreen->setCurrentSize(m_currentSize);
XCB::ScopedPointer<xcb_randr_get_screen_resources_reply_t>
screenResources(XRandR::screenResources());
kscreenScreen->setMaxActiveOutputsCount(screenResources->num_crtcs);
return kscreenScreen;
}
the problem is the screenResources.d is NULL
I don't know the sctructure of the KDE code to know where the right place
is to fix this.
