I cannot reproduce your problem... If set, can you comment out Load "dri" and/or Load "glx" from your X config? Can you try another X driver, ie, vesa? Also, these 2 patches are present in mm but not in Linus' tree. Can you check which of these are the culprit, if any? http://kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.15-rc2/2.6.15-rc2-mm1/broken-out/vgacon-fix-doublescan-mode.patch http://kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.15-rc2/2.6.15-rc2-mm1/broken-out/vgacon-workaround-for-resize-bug-in-some-chipsets.patch Tony
