I'm having similar problems with a G450 It was crashing erratically as described til today (12th Feb), when xorg-x11 6.9.0 arrived in testing. Now it doesn't work at all (direct rendering has been disabled). The relevant parts of Xorg.0.log:
(II) MGA(0): Using overlay video (II) MGA(0): X context handle = 0x1 (II) MGA(0): [drm] installed DRM signal handler (II) MGA(0): [DRI] installation complete (EE) MGA(0): [drm] Failed to map DMA buffers list (II) MGA(0): [drm] removed 1 reserved context for kernel (II) MGA(0): [drm] unmapping 8192 bytes of SAREA 0xd0a3d000 at 0xb615f000 (WW) MGA(0): Direct rendering disabled Hope this in some way helps, I've never managed a working DRI. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
