Whole desktop draws offset to the right in dual monitor mode

Ok, so I have KDE 4.6 installed on Debian Wheeze, and I think I was on KDE 4.5 before upgrading. I had a working dual monitor configuration with the xorg.conf I posted below. At the same time that I updated my system and KDE, I also installed an LCD to replace one of my CRTs, and updated my xorg.conf only slightly (that's where the modeline comes from). Now, when I start up kdm, everything displays just as I'd expect it to with the monitors at the correct resolution. If I move my mouse to put focus on the password box, it works(Of course, that's not surprising as I haven't gotten to the point yet). Everything draws in the right place... But once I log in, it's a whole different ball game.
When logged in, the left monitor's plasma space is drawing on the left side of the right monitor. There is corruption below this because the right monitor(the LCD) is taller, and also wider. On the right side, just before the LCD ends, I can see what should be displaying on the right-hand monitor, just a bit of the k-menu and the left side of the screen. Now, it's bad enough that everything is drawing offset to the right, but if I move my mouse around... Well, trying to click on things doesn't really work. Turns out the coordinates for my mouse are all working perfectly fine. If I move my mouse to the lower left corner of my right monitor, I can open the k-menu.. Of course, the k-menu is over a thousand pixels to the right..... So, I can't see 85% of what should be displaying on my right hand-monitor, everything is being drawn offset to the right by the width of the left monitor, and I don't know what to do. I went into the system settings menu and found the section for multiple monitors where it shows the coordinates and sizes of each monitor, but I couldn't change anything there. However, I noticed it was wrong... It thinks the offset for the right-hand monitor is 1024 pixels, but my left-hand monitor is actually 1152 pixels wide(Note: I'm not sure about this anymore, but it's an unrelated issue and I'll fix it later). Not that this matters, as it's drawing to the right of everything anyway. Xinerama is enabled, and I have a Radeon 9800 as my graphics card with the open source radeon drivers. Also, as a side note, RandR is theoretically enabled according to this message in my Xorg.log: [ 21.836] (II) RADEON(1): RandR 1.2 enabled, ignore the following RandR disabled message. [ 21.836] (--) RandR disabled However, krandrtray and xrandr both seem to believe otherwise.. But then again, I never needed working RandR for this before it seemed. I asked on the Debian forums several days ago and got no response, so I thought I'd try my luck here. Thanks.
And for extra spam, here's my Xorg.0.log:

Can you please write more about your setup? Graphic card, if you use Xinerama etc. Also, I can't see your xorg.conf.

Oops... Looks like I was trying to multitask when I wrote the post and forgot a few details. Updated and added the xorg.conf and some information about the hardware I'm using.

What happens that instead of your xorg.conf.d setup you use the System Settings module to configure your screen?

Ok, I nuked the ServerLayout section in my xorg.conf . I fired up KDM, and it displayed on both monitors in the same resolution. I expected nothing other than that. I logged in, I went to system settings, from there I reconfigured the DVI monitor as being on the left and the VGA as being on the right, and this works. However, I have a couple of new issues with this setup, but we are making progress. Firstly, the resolutions listed for my DVI-connected monitor are the same as the resolutions for the right monitor, timings appear to be separate. I really want to run the left monitor at 1152x864 as I had it before, but since removing the server layout, my specifications for the second head's list of modes is no longer taken into consideration. Secondly, when I log out of KDE and attempt to return to KDM after doing what I described above in the system settings, KDM never gets restarted. I am forced to restart X at this point. Once I do this, I log in and find that KDE has completely forgotten the settings I applied before. As a side note, the LCD monitor absolutely has to have that modeline because its DDC/EDID comes broken straight from the factory. (In case anyone tries to get me to remove it through minimizing my xorg.conf) |

Alright, I changed my xorg.conf around a little bit more. It didn't resolve any problems, but I think it's a better base for my setup.

I believe that to fix KDM not restarting you can set TerminateServer=true in kdmrc (the exact location of the file depends on your distribution).
