Description Samuel Thibault 2014-09-10 09:36:45 UTC
Hello,

I have setup an Xdmx X display, but gtk applications fail to display any text, so I get mostly empty windows. firefox and chromium do manage to render text though.

I have found http://blog.sumostyle.net/2008/10/xdmx-rendering-issues-gtk-qt-and-others/ and thus tried -norender, it indeed fixes displaying text in the gtk applications. As expected, some graphical operations become sluggish. The quickfix patch proposed there doesn't fix anything for me, but I guess that patch was related to https://bugs.freedesktop.org/show_bug.cgi?id=7555 which was fixed a long time ago.

Also, notably, even with the -norender option, gedit fails to start:
(gedit:5359): Gdk-ERROR **: The program 'gedit' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadAlloc (insufficient resources for operation)'.
  (Details: serial 139 error_code 11 request_code 78 (core protocol) minor_code 0)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the GDK_SYNCHRONIZE environment
   variable to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)
zsh: trace trap  gedit

Xdmx session log

What is noticeable in this log is the dmxErrorHandler errors. They happen exactly when I start gnome-terminal.

(I had previously attached an nvidia config, but forget about it, the same happens with just the intel display alone in the Xdmx config).
