I've removed radeon card (radeonsi module causes X crash and this is why autologin fail) I disabled gdm service at all and started gnome-session from tty by xinit script. dmesg output for intel only system: [ 32.537198] [drm] stuck on render ring [ 32.537922] [drm] GPU HANG: ecode 7:0:0x85dfbff9, in gnome-shell [562], reason: Engine(s) hung, action: reset [ 32.537923] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.
