Description of problem: Using the default config of the Fedora 9 preview release install X generally fails to display on my laptop. If the machine has been powered off for a while it tends to display correctly and work, but otherwise (eg. after v-c switch, X restart, suspend-resume, reboot) it almost always fails to initialise the screen correctly. Version-Release number of selected component (if applicable): xorg-x11-drv-ati-6.8.0-10.fc9.x86_64 How reproducible: Most of the time. Steps to Reproduce: 1. Boot machine from cold 2. If a working X display results restart X Actual results: LCD goes blank and then fills up with grey from the bottom taking a couple of seconds. Ends in a light grey steady state with no visible picture. Expected results: Normal X display Additional info: This is the same both with the default xorg.conf generated by anaconda, or if I just remove xorg.conf and let Xorg default by itself. I've attached the log from the default run. radeonhd works fine (except for no suspend to ram) on this machine.

Changing version to '9' as part of upcoming Fedora 9 GA. More information and reason for this action is here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Any ideas on this, or anything I can do to help debug it? It is quite reproducible. Although radeonhd is working for me it doesn't do XV or suspend at the moment, both of which are a serious pain. ati does do those but only works about 10% of the time which is completely useless.
does VT switching help radeon at all? btw radeon shouldn't do xv on that hardware either, it might do suspend better though.
It generally switches out to the vt but fails again back on the X display. Power down and wait a while is about the only way out. Seems worse on the F9 release than it was on the preview release live usb key, though may be just circumstance. Suspend did work sometimes on the preview release, although often it would do the same grey screen on resume. Running radeonhd it always starts to fill the screen with grey from the bottom left but after 1/2s or so it flicks out of it and draws the screen properly. Looks likes some mode setting is missing from or not working in radeon? Any ideas on what else I can try?
okay I've built some packages I'd like you to test for if you could. http://people.fedoraproject.org/~airlied/bz444542/ has two subdirs dce3 and refdiv. I'd appreciate you installing them one by one and seeing if either of them solve the LCD panel problem you are seeing any better.
Awesome - dce3 didn't help but refdiv has fixed it. On bootup the screen starts filling with grey from bottom left but flicks out of it within a second. After that switching to and from VT, and suspend to ram all works normally. Thanks! The next annoying problem is that switching out of X and back (or suspend to RAM) breaks tapping on the touchpad - it works from X server restart due to me adding a synaptics section in xorg.conf. For some reason xorg 1.5 doesn't default to tapping on, which earlier releases did. Not sure which X package to raise that against.
xorg-x11-drv-ati-6.8.0-16.fc9 has been submitted as an update for Fedora 9
There is still a problem on this hardware. When the display is switched off and back on (whether by suspend or just a lid close without suspend) sometimes there is a severe flicker all over the screen. Switching between VTs doesn't fix this. Should I raise a new bug for this? Any extra info that would be useful?
xorg-x11-drv-ati-6.8.0-16.fc9 doesnt change anything on my pc i have a ati hd2400 pro (rv610). i use the "radeon" xorg driver
okay Patrick you must have a different bug, can you open a new bug and attach the xorg logs from -16? Martin - probably worth raising a new bug for the flicker so it doesn't get lost. (please close this bug if -16 fixed the problem for you.)
xorg-x11-drv-ati-6.8.0-16.fc9 has been pushed to the Fedora 9 testing repository. If problems still persist, please make note of it in this bug report. If you want to test the update, you can install it with su -c 'yum --enablerepo=updates-testing update xorg-x11-drv-ati'. You can provide feedback for this update here: http://admin.fedoraproject.org/updates/F9/FEDORA-2008-4517
Closing this as fix has been in updates for a while. Entered flicker issue into new bug #465665.
