Bug ID: 111261 Summary: Screen remains black when 2 monitors are connected Product: DRI Version: DRI git Hardware: Other OS: All Status: NEW Severity: normal Priority: medium Component: DRM/AMDgpu-pro Assignee: dri-devel@lists.freedesktop.org Reporter: fabstz-it@yahoo.fr
With 2 monitors (one on VGA, one on DVI-D), screen turns black while loading system in console When only 1 monitor connected to VGA everything is fine.
There is no problem with kernel 5.2 or with amdpgu-dkms 19.10 on debian buster (linux 4.19)
It happens only with amdpgu-dkms 19.20 or 19.30 (on debian buster - kernel 4.19) For 19.20 I applied my patch from https://bugs.freedesktop.org/show_bug.cgi?id=111103, which is merely the same as the code in 19.30
