I've been trying to get X running on my Compaq Armada M300 laptop (ATI Rage
LT Pro graphics device, 800x600 LCD) using the framebuffer device. The
Linux console is working beautifully at 800x600 using the vesafb driver:
vesafb: framebuffer at 0x40000000, mapped to 0xc8800000, size 4096k
vesafb: mode is 800x600x24, linelength=2400, pages=1
vesafb: protected mode interface info at c000:4dba
vesafb: scrolling: redraw
vesafb: directcolor: size=0:8:8:8, shift=0:16:8:0
Console: switching to colour frame buffer device 100x37
fb0: VESA VGA frame buffer device
But the fbdev driver in X (version 4.1.0.1, shipped with Debian
stable/woody) is refusing to start, claiming that any mode I ask for is
invalid:
(II) FBDev(0): using default device
(II) Running in FRAMEBUFFER Mode
(**) FBDev(0): Depth 24, (--) framebuffer bpp 32
(==) FBDev(0): RGB weight 888
(==) FBDev(0): Default visual is TrueColor
(==) FBDev(0): Using gamma correction (1.0, 1.0, 1.0)
(II) FBDev(0): Hardware: VESA VGA (vidmem: 4096k)
--> (II) FBDev(0): Checking Modes against framebuffer device...
--> (II) FBDev(0): mode "800x600" test failed
(II) FBDev(0): Checking Modes against monitor...
(--) FBDev(0): Virtual size is 1024x768 (pitch 1024)
(**) FBDev(0): Built-in mode "current": 48.0 MHz, 46.9 kHz, 75.1 Hz
(++) FBDev(0): DPI set to (100, 100)
(II) Loading /usr/X11R6/lib/modules/libfb.a
(II) Module fb: vendor="The XFree86 Project"
compiled for 4.1.0.1, module version = 1.0.0
(**) FBDev(0): Using "Shadow Framebuffer"
(II) Loading /usr/X11R6/lib/modules/libshadow.a
(II) Module shadow: vendor="The XFree86 Project"
compiled for 4.1.0.1, module version = 1.0.0
(--) Depth 24 pixmap format is 32 bpp
FBIOPUT_VSCREENINFO: Invalid argument
Fatal server error:
AddScreen/ScreenInit failed for driver 0
(My XF86Config-4 file is appended at the end of this message.)
I've tried everything I can think of, including:
-- default bpp of 15 or 16, instead of 24
-- mode names other than "800x600" (like "defaults," as in 3.3.x)
-- an explicit modeline in the monitor section, with timings given
by 'fbset -x'
but nothing seems to work. Web searches on this error aren't helping much
either. I always get the same error while "checking modes against
framebuffer device."
Can anyone tell me what this means? Is there any way to get more debugging
information? I thought running X with fbdev was a trivial task once the
framebuffer console was working.
Thanks,
Mark
