Description of problem: After update from xorg-x11-drv-ati-6.9.0-63.fc10.x86_64 to xorg-x11-drv-ati-6.10.0-1.fc10.x86_64 X no longer comes up. The screen is blank but ctrl-alt-F2 works to switch to a text console. When I revert to 6.10.0-1, X works again. Version-Release number of selected component (if applicable): 6.10.0-1.fc10.x86_64 How reproducible: always on my system (as far as I know) Steps to Reproduce: 1. upgrade to xorg-x11-drv-ati-6.10.0-1.fc10.x86_64 2. reboot Actual results: blank screen. Expected results: rhgb login screen. Additional info: See attached Xorg.0.log files: one for 6.9.0-63 and one for 6.10.0-1 Here are some notes on the differences. | (II) Module ati: vendor="X.Org Foundation" |- compiled for 1.5.3, module version = 6.9.0 |+ compiled for 1.5.3, module version = 6.10.0 The ATI driver went from 6.9.0.something to 6.10.0.something | (II) Loading /usr/lib64/xorg/modules/drivers//radeon_drv.so |- compiled for 1.5.3, module version = 6.9.0 |+ compiled for 1.5.3, module version = 6.10.0 I think that this is just the same thing. |-(--) RADEON(0): Chipset: "ATI ATI Radeon HD 3600 XT" (ChipID = 0x9598) |+(--) RADEON(0): Chipset: "ATI Radeon HD 3600 XT" (ChipID = 0x9598) Looks like a typo got fixed.

I'm not sure which connector number I'm using. The card has no HDMI connector. It has two DVI connectors and an S-Video connector. One of the DVI connectors is Dual-Link, and that is what I'm using (my monitor requires dual-link). | (II) RADEON(0): Output: HDMI-0, Detected Monitor Type: 0 |-Dac detection success |+invalid output device for dac detection This doesn't look good. | (II) RADEON(0): Output: HDMI-0, Detected Monitor Type: 0 |-Dac detection success |+invalid output device for dac detection Seems like a repeat.

Created attachment 331281 [details] Xorg.0.log for 6.9.0-63 (works)
Created attachment 331282 [details] Xorg.0.log for 6.10.0-1 (fails)
Behaviour of 6.10.0-2 seems the same as that of 6.10.0-1
Hugh, Could you add dmesg output as uncompressed text/plain attachment to this bug ? What happens if you boot with nomodeset ? --- Fedora Bugzappers volunteer triage team https://fedoraproject.org/wiki/BugZappers
Thanks for looking at this, François. I've done 3 new runs 1. using 6.9.0-63 2. using 6.10.0-2 3. using 6.10.0-2 with nomodeset In each case, after waiting for the login screen (whether it appeared or not), I went to console 2 and grabbed a copy of /var/log/Xorg.0.log and dmesg output. Neither 2 nor 3 worked as I had hoped: the login screen was not visible. The dmesg output did not seem to be interestingly different in the 3 cases. The Xorg.0.log for 2 and 3 seemed to be mostly the same. There was a difference in key mapping, but I don't see why. I will attach these captured files.

Hugh, Thank you for the information. Switching Severity to high as this is rather critical. Adjusting Priority accordingly. --- Fedora Bugzappers volunteer triage team https://fedoraproject.org/wiki/BugZappers

*** Bug 486925 has been marked as a duplicate of this bug. ***
This message is a reminder that Fedora 10 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 10. 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 '10'. 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 10'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 10 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 please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. 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. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Fedora 10 changed to end-of-life (EOL) status on 2009-12-17. Fedora 10 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.
