I've had problems at various times during 2.5 with a number of
card-specific framebuffer drivers so I've backed off to only using the
VESA framebuffer driver. Maybe the connection is which framebuffer driver
is used.
I've had the same problem. I've tried using radeonfb and it's never
worked yet since 2.5.69. In 2.6.0, no matter what mode I select, I get
a horizontal frequency of 140kHz and a ~90Hz vertical sync. My monitor
blanks and pops up the on-screen menu with the horizontal frequency
high-lighted in red. My monitor supports up to 110kHz horizontal
according to my X log.
I compiled just the vesafb in as well, but it does the exact same
thing. It doesn't matter what values or modes I put in the vga/video
parameter. Only the text mode works now, and after only 2 days uptime
I've noticed I no longer have the full vertical screen. When I type,
random text or colored/flashing blocks appear in the bottom (roughly)
1/5th of the screen. Actually, anytime I run an ncurse app in my
console, it gets smaller. Now my console only occupies 1/2 the screen,
but it doesn't seem to get any smaller than that. I'm using the boot
parameter "vga=0x132".
My point is maybe your screen isn't blank, but rather the horizontal
frequency is out of your monitor's range?
Certainly, something has changed, because with 2.6.0-test11 I was
running "vga=0x31B video=vesafb:ywrap" and it worked great, whereas now
it doesn't work at all with any fb modes.
