Description of problem: I have what looks like a: houston:~$ lspci | grep VGA 01:00.0 VGA compatible controller: ATI Technologies Inc NI Turks [AMD Radeon HD 6500] I have 3 monitors-- my main Samsung LED 23" (SyncMaster PX2370) over HDMI, and two satellite smaller monitors on either side, both Acer LED 20" (one on the VGA port and one on the DVI-D port). After doing a fresh install of fc17 on x86-64, upon bootup I only get 2 monitors working (the main Samsung LED 23" and one of the Acer LED 20"). However, the 3rd monitor is not working and the X login screen seems to be in the blank 3rd monitor. This 3rd monitor is connected to the DVI-D port of the graphics card. If I only boot with two monitors (the Samsung 23" over HDMI and one of the Acer monitors over VGA, I still can't get a working system as the Acer over VGA is partly garbled. So... trying with 3 monitors gets me 2 working, but unable to log in because the 3rd one is where the login prompt is. Trying with 2 does not work as one of the Acer monitors has half the screen garbled. Interestingly if I boot with only my main Samsung over HDMI monitor, and then plug in both Acer monitors after login, everything works perfectly. I just can't boot with more than one head. My apologies for the long description. Let me know if you need additional data. Version-Release number of selected component (if applicable): I don't know if these are relevant, but: xorg-x11-drv-ati-6.14.4-6.20120602git930760942.fc17.x86_64 xorg-x11-server-Xorg-1.12.2-4.fc17.x86_64 kernel-3.4.6-2.fc17.x86_64 How reproducible: Every bootup.

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 It is Fedora's policy to close all bug reports from releases that are no longer maintained.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.
