I'm sorry, the argument that works is "-screen 0 1024x768x24", NOT "-screen 0 1024x768x32". With x32, I only get "Fatal server error: Couldn't add screen 0", but that's probably another bug. The problem is still present with My version of xvfb is 2:1.19.3-1ubuntu1 according to dpkg -l *xvfb*. I think the solution to this problem would be if Xvfb stopped advertising fbconfig's that do not work. -- GitLab Migration Automatic Message -- This bug has been migrated to freedesktop.org's GitLab instance and has been closed from further activity.

failed to create drawable Error: couldn't create pbuffer When I run the same demo with Xvfb started with "-screen 0 1024x768x32" it works! It chooses 0x69 as well then. What is wrong here? My guess is that fb config 0x69 is actually unsupported for 1024x768x16 but Xvfb advertises it anyway. My version of xvfb is 2:1.11.4-0ubuntu10.1 according to dpkg -l *xvfb*.
