Hello,
after resuming my graphics card sometimes does not come up (see my post
yesterday).
Comparing drm outputs with drm.debug=6 in syslog reveals among others
[drm:intel_crt_detect], CRT not detected via hotplug hotplug"
Does that mean that the monitor (EIZO FlexScan L767) is not reliably detected?
Is that a know problem? Does it make sense to open a bug report?
As a workaround can I enforce that a signal is always driven (it is a desktop,
the monitor is always there!). Or can enforce that the check is repeated once
or twice, if it fails (that should bring the probability down)?
Here the full diff (for *1303* the resume was not working):
