I am running a second X server on a second video card. The problem is when I load glx and dri in both servers, running at the same time, videos played in the second server is lagging and stuttering pretty bad. I have confiremd that not loading glx on the second server removes the stutter. If I manually disable Load "dri" and Load "glx" in xorg.conf before launching the second server I am ok. However doing this each time is not very convenient. I found the "-extension" in the man page. I try to run the second server like this: X -extension XFree86-DRI -extension GLX -ac -nolisten tcp -layout Layout1 :1 glx and dri is loaded anyway, as indicated in the log.
In which man page did you see that extension? The only thing I see in either Xorg or Xserver is the -x switch. Using -x tells the server to *enable* the named extension. I don't see an option to disable an extension.
-extension was added in Xorg 6.8, but it looks like we forgot to add it to the man pages.
Sorry about the phenomenal bug spam, guys. Adding xorg-team@ to the QA contact so bugs don't get lost in future.
I was wrong in my inital report that I saw it in the man page. I got the option from the list that is shown when running "Xorg --help" /Björn bni.swe@gmail.com
Björn Nilsson, Do you still experience this issue with newer soft ? Please check the status of your issue. Or close this bug.
My setup and hardware is completely different today. For example I dont have 2 grahics cards in my computer anymore. I guess if someone tried to accomplish this today, running 2 X servers in parallel would not be the answer.
