Xorg.0.log

With the latest git xorg and the ati driver my crt monitor connected to dsub vga the screen is green.

Everything functions as expected, but it's green for white or green on top of other colors.

Happens with both window managers tested - twm & metacity.
Happens whether drm is loaded or not.

vesa driver is OK.

xorg.conf and log attached. removing Options for gart and exa does not fix.

I haven't tried the ati driver since March, but it worked OK then.

I found that disconnecting my s-video lead fixes this.

It also fixed a couple of issues with compiz - My background image was trashed and when using the enhanced zoom plugin the top 4/5 of the screen could be zoomed seperatly from the bottom 1/5. This is at 1024*768 so I suppose it fits with the s-video res listed in the log.

Sorry to be so slow to test, but the disable TV out patch does not totally fix this.

What happens now is that if s-video is connected I just get a blank screen when I startx with the radeon driver.

Monitor is on (not standby) and I can ctrl alt bs and get console back OK, I can also use the vesa driver OK.

It does not fix it.

To recap and add a bit more info.

With s-video connected.

Bootup screens and console are displayed normally on both TV and vga monitor.

startx = vga monitor black, but on and X is functioning OK AFAICT.
         TV is showing rapidly scrolling black,white,black,white short line pattern.

quit X = vga monitor has normal console back
         TV now has green console with text still visable ie. not the same green as the background green.

I don't have my X1600pro anymore - have a HD3850 now so can't test anymore.

Just before I pulled the X1600 out, I tried the radeonhd driver and the bug exists for that as well.

The bug does not occur with my HD3850 using either driver.

Spoke too soon.

I've just noticed a slight glitch. With the TV on after quitting X (this didn't happen the first time I tested) the VGA console on the monitor and on the TV display had spaces replaced by fat = and - replaced by spaces. Still worked OK.

This maybe a bogus test though, as I had run the vesa driver first and not restarted.

This may be related to bug 16781.  On my mobility X1400, if I have either the VGA or S-video connected when starting X, I get a blank screen on LVDS as well as the VGA or S-video.  However, with no external connection, X starts the LVDS fine.

I re-enabled S-video just to test it.  The tv screen image is garbled, but I don't have any of these problems with green colors.

This should be fixed in git master and 6.12.x.  Please re-open if this is still an issue.
