Description of problem: I tried to create a web sandbox for Firefox. Firefox is running inside the sandbox, but the Xephyr display is either solid black or solid grey, all the time. Version-Release number of selected component (if applicable): policycoreutils-sandbox-2.0.85-12.fc15.x86_64 How reproducible: Always Steps to Reproduce: 1. Install policycoreutils-sandbox 2. Reboot 3. sandbox -X -H sandboxes/music/ -t sandbox_web_t firefox Actual results: The Xephyr display is either solid black or solid grey, all the time. Expected results: Firefox should appear Additional info: Firefox works if I create a blank home directory, set HOME to it, start a Xephyr server on :1 and set DISPLAY=:1 and run Firefox. I experience some very minor graphics corruption issues with this graphics chipset.
Can you try using -W metacity?
It works with -W metacity. If I then run it again without -W metacity, it still works (although there are no window decorations at all - I don't know whether that's expected or not). However, if I then try it again, supplying a different, empty directory as the -H argument, this bug occurs again. I previously tried starting firefox in Xephyr and then running matchbox - that worked. So it may be an issue with the timing of when matchbox is started. This bug does not occur on our Fedora 14 machine - it only occurs on Fedora 15.
