SubjectRe: VESA VGA Frame Buffer
I'm afraid this stuff is still in the realms of a mystery and I've had a good
read of the docs and this list.
On VGA=ask, I get 2 modes that are VESA (7) 0308 (128x25) and (8) 030A
(132x43). With VGA_CONSOLE I get the old stream of message output and I've given
the lilo prompt ...
vga="ask,mode=0778"
vga=vesa:redraw
vga=ask
Next try, I compiled a kernel without VGA_CONSOLE and gave it the command line
vga=0778, at this point it goes to "Loading Linux......", I next get
"Uncompressing Linux", then a black screen below, no logo and I can log in blind
and fire up X. If I use "fbset -s", it reports "open /dev/fb0: Operation not
supported by device", issued from an xterm, but I get the same on my other
machine in VC mode, both cards report VESA VGA for vga=ask, this one is a
stealth 3D 3000 4 Meg and a CL-5446 2 Meg on the other.
dmesg gives .........
Linux version 2.1.111 (root@barrabas) (gcc version egcs-2.90.29 980515 (egcs-1.0
.3 release)) #4 Mon Jul 27 09:39:49 GMT 1998
Console: colour dummy device 80x25
But it doesn't look like an 80x25 screen, the font is quite small. The latest
config I have set............
# CONFIG_VGA_CONSOLE is not set
CONFIG_VIDEO_SELECT=y
CONFIG_FB=y
CONFIG_DUMMY_CONSOLE=y
# CONFIG_FB_VGA is not set
CONFIG_FB_VESA=y
CONFIG_VIDEO_SELECT=y
# CONFIG_FB_MDA is not set
# CONFIG_FB_VIRTUAL is not set
# CONFIG_FBCON_ADVANCED is not set
CONFIG_FBCON_CFB8=y
CONFIG_FBCON_CFB16=y
CONFIG_FBCON_CFB32=y
# CONFIG_FBCON_FONTS is not set
CONFIG_FONT_8x8=y
CONFIG_FONT_8x16=y
Yours truly, truely flummoxed by this one, something I'm definitely missing the
point of and constantly. I haven't been able to establish so far if these cards
are VESA 2.0 or not as I don't have the dos disks around to hand.
