Description Lennart Poettering 2008-09-26 15:17:07 EDT
Created attachment 317830 [details]
xorg.conf, s/radeonhd/radeon/

The newest ATI driver breaks my dualhead RV630 setup: although the driver seems to think it initialized properly, the screens stay black:


readeonhd gets things running properly.

(Do a s/radeonhd/radeon/ in the xorg.conf I am attaching to get the one I used for testing the ati driver)

(As a side note: the ati driver from a few week backs in rawhide used to get one screen initialized, the other one stayed black, which is better but not useful either. No idea what package version that was)
Comment 3 Bug Zapper 2008-11-25 22:14:23 EST
This bug appears to have been reported against 'rawhide' during the Fedora 10 development cycle.
Changing version to '10'.

More information and reason for this action is here:

There have been bunch of bug fixes

Could you retest with the latest kernel 
( -132 at the time of this writing )

You can get the latest kernel build here

And with the latest xorg-x11-drv-ati. 
( -60 at the time of this writing )

You can get the latest xorg-x11-drv-ati build here

And report back if it either improves or fixes this issue..

I am not sure if I can post to this bug or open a new one. I too have an RV630 based card and it also doesn't work with ati (radeon) driver, but works with radeonhd driver. I have installed the latest packages:
xorg-x11-drv-ati-6.9.0-60.fc10.i386 and kernel- but the problem still persists. I am able to switch to external screen using the following commands:
xrandr --output LVDS --off
xrandr --output DVI_0 --mode 1600x1200
xrandr -s 1600x1200

But switching back to internal laptop screen doesn't work, the commands are:
xrandr --output DVI_0 --off 
xrandr --output LVDS --mode 1680x1050
xrandr -s 1680x1050
It gives me an error messages:
xrandr: cannot find crtc for output LVDS
Size 1680x1050 not found in available modes

I am attaching Xorg.0.log separately.

Comment 7 Lennart Poettering 2008-12-17 17:18:35 EST
This works now with the version from Rawhide. However, initialization of the screens is much faster with radeonhd than with ati.

Closing nonetheless.
