It *could* be my CRT but it works on my 3 other KVM'd platforms
flawlessly. Besides, the reason I bought the new G450 was
because the exact same thing was happening with my other v-card.
I tried "mga" and gathered the following data from the failure
dump. [[X did work, but there was this huge, dark band a
couple inches from the top (where the display was much lightr)
and after the drk middle band, the display was also light toward
Here is what I found after I did a shutdown now:
Requesting insufficient memory window!: start 0xfd800000 to 0x7efffff size 0x2000000
(EE) Cannnot find empty range to map base to
(II) Module "ramdac" already built-in
(EE) [drm] drmOpen failed
(EE) DRM(0) [dm] DRMScreenInit failed . Disabling DRI
Does this ring a bell among anybody who is familiar with xorg?
My thinking now is that something is wrong with the video on the
m'board; that both this new G50 and the last card were all right.
