Description of problem: When automatically installed or after a reconfiguration using system-config-display, the output of the X server overdrives data projectors making it impossible to do presentations. A simple patch to the config file fixes this, but it would be much better if this was automatically applied. Version-Release number of selected component (if applicable): xorg-x11-server-Xorg-1.1.1-48-13.0.1.el5 How reproducible: every time Steps to Reproduce: 1. find Thinkpad T43 2. install RHEL configuring with automatically identified display parameters 3. boot into runlevel 5 4. connect to data-projector (one of many different types) Actual results: With default configuration data projector fails to display screen at all or only displays part of screen. Once additional configuration is done by the user data projectors work fine. Expected results: System config display should provide a fully functional configuration where the data projector displays the screen as it appears on laptop. Additional info: The attached patch, applied to xorg.conf corrects this problem.
Created attachment 240431 [details] the patch to xorg.conf which fixes projector
Created attachment 240441 [details] xorg.conf as it's generated by system-config-display by default
Created attachment 240451 [details] truncated output of X as starting up I've cut off the end of the print out once X is up and stable and also xxxed out the machine name.
Created attachment 240461 [details] This is the output with the projector working same log as previous but this time after the patch has been applied to xorg.conf

Could we please get full /var/log/Xorg.0.log attached to this bug? Thank you.
Created attachment 281951 [details] /var/log/Xorg.0.log in the default system configuration First I set .xinitrc to just xterm. Then I start the X server; then I type exit in the X term. The configuration used for this was the default created during system configuration.
Created attachment 281961 [details] /var/log/Xorg.0.log in the patched configuration This log is taken exactly identically to the previous one except that the confirguration used has the patch listed above applied to it.
No further hardware enablement updates are planned for RHEL5's X stack. Note that RHEL6 has vastly improved multihead support for the radeon driver, so this should be fixed there. If it is not, please update the affected product version and reopen this bug.
