Created attachment 598132 [details] dmesg output for normal boot (problem occurs) Description of problem: Seemingly random brief (1 to 10 seconds, typically ~3 sec, occasionally <1sec) blank screen with ATI driver and ATI Radeon RV610 HD2400 Pro, Fedora 17 (fresh install) with gnome desktop. Screen returns after 1 to 10 seconds, during which system responds to keyboard and mouse, so there is no system lockup. Nomodeset at boot (fallback to VESA driver) resolves problem. Problem also occured during Fedora 17 install (graphical from dvd). No indication of problem in any logs. Version-Release number of selected component (if applicable): xorg-x11-drv-ati-6.14.4-6.20120602git930760942.fc17.x86_64 How reproducible: Always Steps to Reproduce: 1. Boot up system. 2. The problem occurs without doing anything, but it's frequency increases when using the mouse or keyboard (which causes screen update). Typical frequency is as high as 1/sec to as little as 1/minute. Screen paging (selecting a new window as in switching between Activities and Applications in Gnome desktop always produces the problem. Actual results: Screen goes blank without system lockup for short period of random length. Expected results: Screen should not go blank. Additional info: Using USB keyboard and mouse. No xorg.conf file. Will attach dmseg, smoldt profile, glxinfo, and messages from boot with drm.debug=14 set.

This message is a reminder that Fedora 17 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 17. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '17'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 17's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 17 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior to Fedora 17's end of life. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
Fedora 17 changed to end-of-life (EOL) status on 2013-07-30. Fedora 17 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed.
