I want to run mozilla on Xvfb to get some screenshots
of web pages.
I start Xvfb with the command:
Xvfb :30 -ac -screen 0 1024x768x24
Which creates an Xvfb server with 1024x768 resolution
and a color depth of 24 (16.7 million colors).
Then I run mozilla:
mozilla --display :30.0
And get the following error message:
Gdk-ERROR **: BadLength (poly request too large or
internal Xlib length erro
serial 1240 error_code 16 request_code 148
I've tried other programs like gshell, gedit with the
I also have the same problem with a color depth of 16.
But, when I run Xvfb with a color depth of 8 (only 256
colors), gtk programs run fine.
If I run a Qt based program, with a depth of 16 or 24,
when I try to take a screenshot, my screenshot program
(graphicsmagick) locks up.
I am running Redhat 9 on an i686 with XFree86-Xvfb 4.3
Why is this happening? Is there a solution?
