I upgraded to kernel 2.4.9 about a week ago. I'm using XFree 4.0.3 on a mostly woody system. My graphics card is a Matrox G400.
Under 2.4.7 and 2.4.8, direct rendering under X worked without a problem. But under 2.4.9. I get these errors in the XFree log: . . (EE) MGA(0): [drm] MGADRIScreenInit failed (DRM version = 3.0.2, expected 2.0.x). Disabling DRI. (II) MGA(0): Using 6417 lines for offscreen memory. (II) MGA(0): Using XFree86 Acceleration Architecture (XAA) . . (==) MGA(0): Backing store disabled (==) MGA(0): Silken mouse enabled (II) MGA(0): Using overlay video (II) MGA(0): direct rendering disabled Under 2.4.8 and 2.4.7, there were no error messages (or relevant warning messages), and direct rendering was enabled. It's easy enough to go back to 2.4.8, but I'd like to understand what's going wrong under 2.4.9. Any clues? Thanks in advance. Jim
