If downgrading the kernel makes the problem go away, there are not many possible reasons: * Are you using the intelfb kernel module? * DRI should work the same with both kernel since you have a i945. > SubSection "Display" > Depth 24 > Modes "1400x1050" > Virtual 2680 2048 > EndSubSection > [...] > (II) intel(0): Increasing the scanline pitch to allow tiling mode (2688 -> > 4096). > (II) intel(0): Memory allocation layout: > (II) intel(0): 0x00000000-0x0001ffff: ring buffer (128 kB) > (II) intel(0): 0x00020000-0x00029fff: HW cursors (40 kB, 0x 1f820000 > physical) > (II) intel(0): 0x0002a000-0x00031fff: logical 3D context (32 kB) > (II) intel(0): 0x00032000-0x00032fff: overlay registers (4 kB, 0x > 1f832000 physical) > (II) intel(0): 0x00040000-0x02a1ffff: front buffer (42880 kB) > (II) intel(0): 0x007bf000: end of stolen memory > (II) intel(0): 0x02a20000-0x09217fff: exa offscreen (106464 kB) > (II) intel(0): 0x09218000-0x0b217fff: back buffer (32768 kB) > (II) intel(0): 0x0b218000-0x0d217fff: depth buffer (32768 kB) > (II) intel(0): 0x0d218000-0x0d417fff: DRI memory manager (2048 kB) > (II) intel(0): 0x0d418000-0x0f417fff: textures (32768 kB) > (II) intel(0): 0x10000000: end of aperture > (II) intel(0): front buffer is not tiled > (II) intel(0): back buffer is not tiled > (II) intel(0): depth buffer is not tiled > (EE) intel(0): Cannot support DRI with frame buffer width > 2048. > Can you try without such a big virtual screen? 2048x248 is supposed to work fine. When you try more, like above, DRI is disabled, and I think there could be some other problems, for instance https://bugs.freedesktop.org/show_bug.cgi?id=11453 Brice -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
