Comment 5 for bug 1848746

I made the switch to 19.10 and the problem is the same in the logs. There is a slight difference however, the screen doesn't flicker any more upon the change request. I suppose it now detects the adjusted modeline is the same as the current one, hence nothing to do.

Here's some output extracted from dmesg (ISO date format) :

2019-11-04T16:39:13,088276+01:00 [drm:intel_dump_pipe_config [i915]] requested mode:
2019-11-04T16:39:13,088290+01:00 [drm:drm_mode_debug_printmodeline [drm]] Modeline "": 0 92450 1920 1968 2000 2080 1080 1083 1088 1111 0x0 0x9
2019-11-04T16:39:13,088323+01:00 [drm:intel_dump_pipe_config [i915]] adjusted mode:
2019-11-04T16:39:13,088336+01:00 [drm:drm_mode_debug_printmodeline [drm]] Modeline "1920x1080": 60 140490 1920 1972 2007 2094 1080 1083 1089 1118 0x48 0x9

So it's the current 19.10 kernel (5.3.0-19-generic). I'm considering trying v5.4-rc5. I will report back once (and if) it's done.
