All linux performance tests fail with message: Xlib: extension "RANDR" missing on display ":9.0"

Hello. I'm trying to get results of peformance tests for Chromium project. I use "master.chromium" as a master and "chrome-linux-perf" slave. I use Fedora 12 (32 bit) OS and  I successfully build chromium and chromium.r61483.tgz archive as a base code. Its updated by gclient to the recent code successfully. When it comes to the perf tests, all of them fail and get this message:

Xlib:  extension "RANDR" missing on display ":9.0".

Can anyone help me to understand whats wrong with it ?

More detailed log is here:
