After loading nouveau.ko the main display on LVDS-1 switches to hi-res framebuffer (KMS) like during normal boot. But when X is started, it switches to vt7 and then nothing happens - neither is the frame buffer is redrawn anymore, nor the external display is enabled. This is not a lockup, though. I can switch back to vt1 with ctrl-alt-f1, and I can login into the x session by blindly typing username/password (though xdm) or start gtk-demo from vt1. (Same happens if I just start X with "X -wr&" .) [in brief] xorg.conf: ----> snip -----> Section "Device" Identifier "Card0" Driver "nouveau" VendorName "nVidia Corporation" BoardName "NVIDIA Quadro NVS 3100m" BusID "PCI:1:0:0" EndSection <---- snap <----- steps to reproduce: - boot and load nouveau.ko - start X with "X -wr -config ./xorg.conf&" result: - KMS console works, but - X stops redrawing the frambuffer switching to vt7 does not change the screen expected: - KMS console works - X draws a blank white screen on LVDS-1 (in vt7) - xrandr can enable DP-1 [notes] kernel reports several: [drm] nouveau 0000:01:00.0: 0xD404: Init table command not found: 0x3A errors. what is SOR?
