Bug still present in amdgpu-pro-19.30-855429-ubuntu-18.04 Last working version is amdgpu-pro-19.10-785425-ubuntu-18.04 Please attach your xorg log (if using X) and your dmesg output. What GPU are you using? Thanks for your interest in that issue. How could I do that with nothing visible on my monitors ? Is there any parameter I can add to the kernel to keep a log ? Created attachment 145098 [details] System information (part1) Please find attached: - basic configuration details. - addition information As instructed here : https://amdgpu-install.readthedocs.io/en/latest/install-bugrep.html Created attachment 145101 [details]
System information (part2 = logs)
I could get the logs/info through SSH
There was no Xorg.log probably because the system didn't start X
There is no dedicated GPU on my system but an APU/CPU with integrated graphics :
"AMD Athlon 200GE with vega graphics"
BTW, running kernel 5.2.x was fine (both monitors had something displayed)
The issue seems to be related to these calls in file amdgpu-19.30-855429/amd/display/amdgpu_dm/amdgpu_dm.c twice: kcl_drm_dp_cec_unset_edid(&aconnector->dm_dp_aux.aux); once: kcl_drm_dp_cec_set_edid(&aconnector->dm_dp_aux.aux, aconnector->edid); If I delete them the display works also with 19.30 -- GitLab Migration Automatic Message -- This bug has been migrated to freedesktop.org's GitLab instance and has been closed from further activity.
