Again, don't know, but it would seem as though the 24 is the depth. As you have referred to bpp before, I assume that is what you mean. https://en.wikipedia.org/wiki/Color_depth According to the man page for xvfb https://www.x.org/archive/current/doc/man/man1/Xvfb.1.xhtml " −screen screennum WxHxD This option creates screen screennum and sets its width, height, and depth to W, H, and D respectively. By default, only screen 0 exists and has the dimensions 1280x1024x8. " Where the last number is the depth. Previously Adam mentioned that GLX only works at 16 or 32. I just noticed an inconsistency. It would seem feasible to try that command if xvfb-run takes the switches xvfb does. I am thinking; xvfb-run -s '-screen 0 1024x768x32' or xvfb-run -s 'screen 0 1024x768x16' If you follow what I am saying. -eg _______________________________________________ xorg@lists.x.org: X.Org support Archives: http://lists.freedesktop.org/archives/xorg Info: https://lists.x.org/mailman/listinfo/xorg Your subscription address: %(user_address)s
