Xorg.0.log

This time Xorg could not restore the color palette after reenabling the external screen. Trying to disable and reenable the ext. scr several times did not bring back the correct color palette.

xorg-x11-server-7.4-50.2
xorg-x11-driver-video-radeonhd-1.2.5_20090506_4be5f71-2.13

disable:
> xrandr --output DVI-D_1 --off
reenable:
> xrandr --output PANEL --mode 1920x1200;
> xrandr --output DVI-D_1 --mode 1920x1200 --right-of PANEL;

How is the colour palette corrupted?

You can use rhd_dump to get a dump of the LUT.
Comment 3 Elmar Stellnberger 2009-09-04 05:10:41 UTC 
The colors have showed up totally wrong. It was hardly possible to
recognize anything on the screen (will post an rhd_dump if it happens
again).

Where can I find rhd_dump?

> Where can I find rhd_dump?

Under utils/conntest/ if you're compiling from source.  Whether or not it's installed along with a package is up to the distro.

rhd-dump, with radeonhd-1.2.5_20091001_be7216f-13.1

persists with xorg-x11-driver-video-radeonhd-1.2.5_20091001_be7216f-13.1.
reproducible: always occurs if s2ramed while external monitor off:
steps to reproduce:
xrandr --output DVI-D_1 --off;
powersave -u
xrandr --output PANEL --mode 1920x1200;
xrandr --output DVI-D_1 --mode 1920x1200 --right-of PANEL;
Comment 8 Elmar Stellnberger 2009-10-13 08:52:24 UTC 
Color palette can be restored by switching from vt07 to vt02 and back again.
Output of rhd-dump does not differ before and during color palette corruption.
Comment 9 Yang Zhao 2009-10-13 09:52:13 UTC 
This is fixed in 1.3.0
