Description Aaron Plattner 2008-05-05 16:42:54 UTC
Xephyr fails to run on a Linux x86_64 system because hostx.c is built with _XSERVER64 defined.  It dies with this error:

X Error of failed request:  BadDrawable (invalid Pixmap or Window parameter)
  Major opcode of failed request:  55 (X_CreateGC)
  Resource id in failed request:  0x0
  Serial number of failed request:  7
  Current serial number in output stream:  12

This happens because RootWindow(HostX.dpy, HostX.screen) is returning None.

This broke with this commit:

    Xephyr: check presence of extensions in host X
        * hw/kdrive/ephyr/hostx.c,h:
          (hostx_has_dri): added these new entry points
        * hw/kdrive/ephyr/ephyrdriext.c:
          check presence of DRI and XShape extensions before
          trying to use them.
        * hw/kdrive/ephyr/ephyrglxext.c:
          check presence of glx extension before we use it.

which causes that file to include kdrive-config.h, which in turn includes dix-config.h, which defines _XSERVER64.

I seem to have come across this in Fedora 9.
Comment 2 Dodji Seketeli 2008-06-20 07:35:29 UTC
Okay, if you don't mind, I will look at this.
Comment 3 Martin Dengler 2008-06-29 07:33:12 UTC
Thanks for looking at this!
Comment 4 Pascal Scheffers 2008-07-15 04:49:53 UTC
I'd love to see this fixed. It prevents me from running a working OLPC emulator on my Fedora 9 laptop 
Comment 5 Julien Cristau 2008-07-22 12:54:44 UTC
Dodji, any progress on fixing this, or should we just revert the bad commit for 1.5?
Comment 6 Dodji Seketeli 2008-07-22 13:21:44 UTC
I have just got myself an x86_64 box to test this. Before that I didn't have such an environment.

I will be able to test the problem and hopefully come to a solution.

I am very sorry for the delay.
Comment 7 Dodji Seketeli 2008-07-22 16:13:32 UTC
So have committed http://gitweb.freedesktop.org/?p=xorg/xserver.git;a=commit;h=5de1867fbb0a336ff3fdc92cbf734849f6111b1b that seems to fix it for me.

I have also committed a patch to fix various build issues on X86_64.

I hope it works for you.
Comment 8 Hubert Figuiere 2008-07-22 16:54:42 UTC
I applied the patches and now it works here on x86_64

Thanks a lot.
Comment 9 Martin Dengler 2008-08-29 13:34:23 UTC
Just wanted to say thanks - I've been using the rpms at http://koji.fedoraproject.org/koji/buildinfo?buildID=57371 with this patch and it's great.
