Please change your input timing to 1920x1200@60Hz or any other monitor listed timing as per the monitor specifications." The box is still responsive, I can reboot it with Ctrl-Alt-Del but screens are blank. If I boot with radeon.modeset=0, I see the normal nomodeset big letters on the console and not very optimal screen resolution. Diffing drm init chatter from dmesg shows only this: --- /tmp/working 2014-04-15 08:40:21.979985352 +0200 +++ /tmp/b0rked 2014-04-15 08:40:11.983985364 +0200 @@ -44,4 +44,5 @@ [drm] pitch is 7680 fbcon: radeondrmfb (fb0) is primary device radeon 0000:01:00.0: fb0: radeondrmfb frame buffer device -[drm] Initialized radeon 2.37.0 20080528 for 0000:01:00.0 on minor 0 +[drm] Initialized radeon 2.38.0 20080528 for 0000:01:00.0 on minor 0 + Below is the whole thing, btw.
