Comment 174 for bug 185311

Dear Bryce,

Thanks for your hard work and the temporary workaround with the non-xcb libx11.

Unfortunately the problem is real and hurting and needs a proper fix for Hardy. I have come across a number of trusted old applications which fail in a similar way when running with the xcb based libx11 under Hardy.

I have created a minimal X11 program which demonstrates at least one aspect of the problem. It should help you to debug the problem and verify a solution.

I have attached the source, makefile, binary and a sample error log as a gzip-ed tar file.

To run the program from bash:

1) extract the files: tar -xzf x11test.tar.gz
2) build: make
3) run: ./x11test
4) note the error messages (Locking assertion failure ...)

Please note that this program (and the original from which this was cut&pasted from) runs fine on a large number of other OS platforms including earlier versions of Ubuntu, Redhat, FreeBSD, Mac OS X, Solaris etc.

Let me know if you need any more supporting material.

Best regards from Perth/Australia

Tom Hunter

The last several comments is doing nothing at all to help the case of
those wishing to revert libx11. Still no data about *specific* apps
with *specific* problems (backtraces or at least stderr msgs) are NOT
being posted to this bug report. If problems are so pervasive, then I
would expect it to be a simple matter to reproduce and post some factual
details (screenshots, error logs, *something*).
