hi michel, without xorg conf on cyrus+ p5020, and g5 quad i have only the black screen with pulse cursor. i need to made it and put in etc/X11/ or not desktop at all.
about modeset=0 on both cards: yes i know is normal dont have video but i think the more strange is have the opposite compared the kernel options . with kernel radeon. modeset=0 and nouveau.modeset=1 look like xorg understand to activate the radeon and deactivate the nouveau . and this make the system stalling without any way to recover. about radeonsi, will check on 7750 too and report. for now 4xxx,5xxx,6xxx can say are running on ppc system with 3d too , yes many endianess on egl and egl2 colors not right and some creazy texture on some games but ... running ;-) ciao luigi Inviato da iPad > Il giorno 30 apr 2016, alle ore 09:10, Michel Dänzer <mic...@daenzer.net> ha > scritto: > >> On 23.04.2016 02:06, luigi burdo wrote: >> >> On Quad G5 with 2 video boards >> if i set radeon.modeset=1 nouveau.modeset=1 Xorg -configure dont found >> at all the video boards >> if i set radeon.modeset=0 nouveau.modeset=1 Xorg -configure dont found >> the nouveau board >> if i set radeon.modeset=1 nouveau.modeset=0 Xorg -configure dont found >> the radeon board > > Xorg -configure has various known issues and shouldn't be used anymore. > Xorg is normally able to automatically detect and use all GPUs in a > system without any xorg.conf file. > > >> if i set radeon.modeset=0 nouveau.modeset=0 no video working ... no tty >> too ;-) > > That disables both kernel drivers, which are required for fbcon and Xorg. > > >> On P5020 >> last of my test is this machine with a radeon hd 7770 core edition >> if radeon drv is running the system run in softpipe mode and i face many >> drm errors and fence issue. >> i atteched the dmesg files. > > Which kernel version are you testing?
