strace X server will halt it
Last modified: 2008-04-25 13:20:35 EDT
Description of problem: There seems to be some deadlock problem when stracing x.org XServer in a gui terminal. Version-Release number of selected component (if applicable): xorg-x11-server-Xorg-1.3.0.0-44.fc8 How reproducible: always Steps to Reproduce: 1. open xterm, gnome-terminal or whatever gui terminal you use 2. become root 3. get pid of X 4. strace -p $pid 5. move mouse around Actual results: XServer hangs Expected results: XServer should run
Could we get please at least partial result of the strace? And also /var/log/Xorg.0.log might be interesting as well. Please, attach these files as separate uncompressed attachments to this bug. Thank you.
Hi, discussion with some co-workers brought up that this may be simply a full x-server queue. The problem is, that it runs well, as long as you don't generate new x-messages (mouse move, new window etc)
Created attachment 302472 [details] strace of Xorg
You're attaching strace to the X server. You're expecting the X server to display the results. Which will cause more X server activity, which will make it print more things, which... I highly recommend not doing this.
