[Linux-fbdev-users] X over fb: "EGA/VGA planes are not yet supported by the fbdev driver [1]"

Attachments: XF86Config-4 XFree86.0.log

Hello everyone

Trying to get the xserver (Knoppix 3.8 XFree86 4.3.0.1) over framebuffer. 
The hw is the following:

0000:00:02.0 VGA compatible controller: Intel Corp. 82852/855GM Integrated 
Graphics Device (rev 02)
0000:00:02.1 Display controller: Intel Corp. 82852/855GM Integrated 
Graphics Device (rev 02)

(btw, why do I get 2?) If I try he intelfb kernel driver, I get

intelfb: intelfb_init
intelfb: Framebuffer driver for Intel(R) 830M/845G/852GM/855GM/865G/915G chipsets
intelfb: Version 0.9.2
intelfb: intelfb_setup
intelfb: no options
intelfb: intelfb_pci_register
intelfb: fb aperture: 0xd8000000/0x8000000, MMIO region: 0xe8180000/0x80000
intelfb: 00:02.0: Intel(R) 855GME, aperture size 128MB, stolen memory 32636kB
intelfb: fb: 0xdb012000(+ 0x3012)/0x400000 (0xd1992000)
intelfb: MMIO: 0xe8180000/0x80000 (0xd1e00000)
intelfb: ring buffer: 0xdb001000/0x10000 (0xd1981000)
intelfb: HW cursor: 0xdd24000/0x1000 (0xd1991000) (offset 0x3011) (phys 0xdd24000)
intelfb: options: vram = 4, accel = 1, hwcursor = 1, fixed = 0, noinit = 0
intelfb: options: mode = ""
intelfb: Non-CRT device is enabled ( LVDS port ).  Disabling mode switching.
intelfb: Video mode must be programmed at boot time.
intelfb: cleanup

I tried setting "vga=..." - no way. With vga16fb I can boot with the 
framebuffer, i.e. it will be used by the console, but I cannot get X 
running over it. I can run it over i810 X driver, but I need fb... 
XF86Config-4 (BusID under "Card1" is just a test - tried without any too) 
and XFree86.0.log attached.

BTW, the reason why I want to run X over fb is, that I need to use 
touchscreen, about which I read in a HowTo, that it only works if X runs 
over fb, is it still true?

Any hints would be greatly appreciated
Thanks in advance

Try vga=ask.  Then choose from those options until you get a framebuffer,
vesafb or intelfb.

Default vga16fb mode is planar, and I don't believe X supports that yet.

Hm, did try that, but will try again.

"default" - you mean, I can switch it to another mode? A brief look 
through Documentation/fb / fbdev.c didn't reveal any useful info.

I tried vesafb shortly too - to no awail...

Thanks

Just tried all (reasonable) options - no success.

[Linux-fbdev-users] orig_video_isVGA (was X over fb: "EGA/VGA planes are not yet supported by the fbdev driver [1]")

From: <gl...@ds...> - 2005-09-05 15:23:51

As a follow-up to the previous thread, but not hardware-specific: where 
is the screen_info.orig_video_isVGA variable set and is it user-settable?

Actually, is the test

 	if (FIXED_MODE(dinfo) && ORIG_VIDEO_ISVGA != VIDEO_TYPE_VLFB) {
 		ERR_MSG("Video mode must be programmed at boot time.\n");
 		cleanup(dinfo);
 		return -ENODEV;
 	}

in intelfbdev.c (2.6.13) correct? (ok, this one is hardware-specific, 
maybe).

Thanks

This is set in arch/i386/boot/video.S with the vga= parameter.

VIDEO_TYPE_VLFB is VESA graphics mode.

Yes, the vga16fb code does support packed-pixel mode.  You have to
do an fbset -nonstd true.  But I haven't checked this functionality yet,
it probably depends on the hardware, probably works in 2.4, but I'm not
sure in 2.6.

EZFB has an example touch screen application that has nothing to do with X.
It reads directly from the touch screen device and translates coordinates
from the physical touch screen to the visible frame buffer resolution.

Look at "tsc"

Thanks, James. I'll have a look, although, I think, we really need a 
complete support for the touchscreen as an input device.

Thanks
