Description Patrice Vetsel 2009-02-06 02:57:05 UTC 
I'v reported this bug on Ubuntu Jaunty (9.04) :
https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/325394


xserver-xorg-video-radeon 1:6.10.0-1ubuntu1 claim to support "RV770 Radeon HD 4850/4870" (from man radeon) but in fact, when xorg come up screen go white and system freeze.

Comment 1 Alex Deucher 2009-02-09 06:22:41 UTC 
Please attach your xorg.conf and xorg log.
Comment 2 Patrice Vetsel 2009-02-10 07:00:37 UTC 
the xorg.conf is empty -> Xorg detection
or the xorg.conf is a failsafe xorg.conf with just driver set to "ati"
Comment 3 Alex Deucher 2009-02-10 07:38:59 UTC 
please attach your xorg log.  It should be in /var/log/Xorg.*.log

This is the log from vesa. If ubuntu safe mode kicks in, it will run vesa.  The ati log should be one of the other Xorg logs in /var/log.
Comment 6 Patrice Vetsel 2009-02-11 09:57:39 UTC 
Nothing is wrote on Xorg.log.
I'v set it empty.
modified xorg.conf -> set driver=ati
reboot
when xorg launch->white screen...3 seconds later system reboot.
I boot under another linux system, access Xorg.log and is always empty
Comment 7 Patrice Vetsel 2009-02-11 21:59:58 UTC 
Bug is not resolved in newer xserver-xorg-video-ati (1:6.10.99.0-1ubuntu1)
Comment 8 Patrice Vetsel 2009-02-18 21:30:31 UTC 
Bug is confirmed by Bryce Harrington  on
https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/325394
with another 4850
Comment 9 Alex Deucher 2009-02-19 07:22:18 UTC 
please try ati git master. I think commit 42492c70c481c88911337eefb97ba9d030adf7b6
should fix it.
Comment 10 Alex Deucher 2009-02-19 10:54:12 UTC 
This seems to only affect 1 GB cards.
Comment 11 Patrice Vetsel 2009-02-19 11:52:30 UTC 
Bryce Harrington have made a package with this patch but this is not solving the bug for me :(
Comment 12 Alex Deucher 2009-02-19 16:00:56 UTC
