Maybe the one with no info is a restarted one? Could you please also check what's in dmesg, maybe there would be some clue? To collect info, you could run the xorg bug script and attach its output: /usr/share/bug/xorg/script 3>/tmp/script.log Also, you could try with the kernel in experimental (2.6.37), or with the X stack from experimental. > As using the vesa driver was no viable option (no direct rendering, > no video overlay) I ended up downgrading all xorg packages the the > old lenny versions (I just kept the xserver-xorg control package > from squeeze and rebuild it with relaxed version dependancies so apt > would not complain). Maybe fbdev would ease the pain? KiBi.
