Description of problem: Single screen display (laptop monitor) works correctly. When a second monitor is attached, nothing happens. When I open Displays to configure the additional monitor, visual corruption occurs on both displays (symptom a). I can switch into mirrored mode using the fn-F7 hotkey and then switch out of it, leaving both displays set to the same resolution. Switching either monitor to a higher but hardware-supported resolution causes the same visual corruption (symptom b). Version-Release number of selected component (if applicable): Version: 6.14.1 Release: 1.20110504gita6d2dba6.fc15 (from "yum info xorg-x11-drv-ati") How reproducible: Always Steps to Reproduce (a.): 1. Attach additional monitor Steps to Reproduce (b.): 1. Change to mirrored mode with hotkey 2. Change out of mirrored mode using hotkey or the now usable interface 3. Increase the resolution output on either display Actual results: Visual corruption Expected results: a. Lack of visual corruption b. Extended desktop with each display at its maximum resolution Additional info: Running on a Thinkpad T42 with a Radeon 9600 (listed as Gallium 0.4 on ATI RV350 in System Info). Notebook display has a resolution of 1400x1050. Secondary display (over VGA) has a resolution of 1600x1200. Mirrored mode uses a resolution of 1280x1024 on both displays. Extended mode works without visual corruption with both displays at 1280x1024. Similar to this bug: https://bugzilla.redhat.com/show_bug.cgi?id=692191 but I experience far more severe visual corruption.
Additional experimentation revealed the following: Valid resolution combinations (notebook display, monitor): 1400x1050, 1152x864 Disabled , 1600x1200 800x600 , 800x600 Resolutions that cause corruption: 1400x1050, 1280x1024 I have also tried the fglrx driver but it does not recognize my video card.

If you have time to update the package and re-test, please do so and report the results here. You can obtain the updated package by typing 'yum update xorg-x11-drv-ati' or using the graphical updater, Software Update. If this error is still persistient on the current software package, please respond and attach a dmseg output in plain text format as well as a copy of the X Server config file if in use (/etc/X11/xorg.conf) as well as the X server log file (/var/log/Xorg.*.log). Also if using a custom X Server config file, please test run system without the X Server config file to allow X to auto-detect hardware. If issue still exists after the above steps have been done, please respond with the above info for further review. --- Jason Fedora Bugzappers volunteer triage team https://fedoraproject.org/wiki/BugZappers
I'm sorry; I no longer have the hardware I was using at the time.
