RaspberryPi 2 - xorg.conf file HELP

G

Greg Quinlan

Hi,

I have managed to get
xorg
mate
mate-desktop
xf86-video-fbdev
and with all the dependencies to compile/install on my RPI2 running FreeBSD11.
(a combination of qemu-arm emulation & native arm compiling with some quick hacks to src code etc)

The last thing remaining is to get a basic /etc/X11/xorg.conf file that will work with the RPI2

I have tried Xorg -configure and edited the file manually ... here is the current state. (I don't understand the layout.. I am just guessing)


Code: 
Section "ServerLayout"
  Identifier  "X.org Configured"
  Screen  0  "myfb" 0 0
  InputDevice  "Mouse0" "CorePointer"
  InputDevice  "Keyboard0" "CoreKeyboard"
EndSection

Section "InputDevice"
  Identifier  "Keyboard0"
  Driver  "kbd"
EndSection

Section "InputDevice"
  Identifier  "Mouse0"
  Driver  "mouse"
  Option  "Protocol" "auto"
  Option  "Device" "/dev/sysmouse"
  Option  "ZAxisMapping" "4 5 6 7"
EndSection

Section "Device"
  Identifier "myfb"
  Driver "fbdev"
  Option "fbdev" "/dev/fb0"
EndSection

Section "Monitor"
  Identifier  "Monitor0"
  VendorName  "Asus"
  ModelName  "24inch"
  Option "DPMS"
EndSection

I know there is a newer /usr/local/etc/X11/xorg.conf.d directory but this seems far too complicated for what I need.

As soon as I get the graphical environment working I will clean up the image and share it.

Thanks for you help

I think you need to change the depth to 24:
Code: 
(EE) scfb(0): specified depth (16) or bpp (16) doesn't match framebuffer depth (24)
 
The packages were not available using pkg install <pkg>. Which means they did not compile for the ARM platform.

When I tried to compile them myself from the ports, all failed with various issues... i.e. core dumps or other "silly" errors.

For those that would not compile (e.g. core dump) I compiled some using qemu on a amd64 version of FreeBSD, but qemu has issues with scripts, it was ignoring the script directive on the first line (i.e. /usr/local/bin/python27 or setenv python27)... I created a shell script which basically called a renamed version of the original script.... e.g. /usr/local/bin/python 27 <original script> $*"

Other ports didn't compile because of path issues.... not patched properly. i.e. one port was calling /nxb-bin/usr/bin/cc which was changed to /usr/bin/cc in all the Makefiles.

I probably should have been making notes... LOL
 
Changed depth to 24

I have the RPI2 plugged into a 4K 60" Panasonic TV via a HDMI port.

This is where it is unhappy....

/usr/ports/x11-drivers/xf86-video-scfb/work/xf86-video-scfb-bdeb3bf/src/scfb_driver.c

Starts at line 431

Code: 
/* Check consistency. */
  if (pScrn->bitsPerPixel != fPtr->info.vi_depth) {
  xf86DrvMsg(pScrn->scrnIndex, X_ERROR,
  "specified depth (%d) or bpp (%d) doesn't match "
  "framebuffer depth (%d)\n", pScrn->depth,
  pScrn->bitsPerPixel, fPtr->info.vi_depth);
  return FALSE;
  }
 
To got this working by editing (hacked)

/usr/ports/x11-drivers/xf86-video-scfb/work/xf86-video-scfb-bdeb3bf/src/scfb_driver.c

Added

Code: 
/* temporary hack */
pScrn->bitsPerPixel = fPtr->info.vi_depth;

/* Check consistency. */
  if (pScrn->bitsPerPixel != fPtr->info.vi_depth) {
  xf86DrvMsg(pScrn->scrnIndex, X_ERROR,
  "specified depth (%d) or bpp (%d) doesn't match "
  "framebuffer depth (%d)\n", pScrn->depth,
  pScrn->bitsPerPixel, fPtr->info.vi_depth);
  return FALSE;
  }

then I rebuilt the driver

cd /usr/ports/x11-drivers/xf86-video-scfb/work
rm .build* .install* .stage* stage*
cd ..
make deinstall
make install

Then started x11/mate-desktop

xinit mate-session

WORKS!!! (GUI x11/mate-desktop)

So the /etc/X11/xorg.conf is good... but there appears to be a strange issue...
perhaps around the resolution which seems a bit odd.
