Is bug in xorg 1:7.3+18 or kdetv 0.8.9-1

Ladies & Gentlemen

Hope this helps someone >tail [solved]

I am having some issues with the new xserver auto config thingy. I was not even aware that anything had changed with the setup of xorg until now. Would have been nice to be told.

What seams to be happening goes like this;

launch system & log into kde

launch kdetv

close kedtv

restart system & login > initial login screen is fine but when kde comes up there are 2 images of the desktop and they scroll by horizontally. If the mouse pointer is placed at the extreme lower right or left corner of the display the scrolling stops but there are still 2 images, also moving the mouse pointer vertically causes the lower portion of the screen to go black in relation to where the pointer is.

kill x with ctrl+alt+backspace repeatedly until x no longer starts (5 or 6 times)

restart with ctrl+alt+delete or some other method that is still available ( on this machine ctrl+alt+F* causes the machine to restart in said f-console when attempting to restart x and the keyboard is non-functioning)

login and everything works correctly.

More possibly related info. When trying to use suspend2disk, which seams to work, the tv-capture card will not display video. A reboot (see above) fixes this.

The above reboot / login issue seams to go away if I set the screen res to 800x600 which it defaults to. Checking the box to "apply on kde startup" with the res set to 1024x768 causes a 4 images to be displayed briefly while x starts and seams to be behind the login issues.

The hardware
cpu p4 @ 2.8 GHz
sys bus 400 MHz
main board Intel atx D845CVSR
mem 512m
Intel Extreme Graphics (on board)
Realtek ALC202A (on board)
TV Wonder VE capture card

The install is clean from Debian Lenny RC. The eventual goal is to set this box up as a MythTV backend server for the rest of my network. MythTV is installed but I have not gotten the card to work with it yet. I think I need to get a subscription for the channel info. But The other three TV programs I have tried have all worked at one time or another.

I am not sure if the X graphics problem I am having is isolated to X or KDEtv or a combination of both (don't know about the other 2 programs they are malfunctioning at the moment). I have done some looking on Google but have not seen where anyone was talking about this problem. It is not that I can't login or change resolutions (in fact I have a bunch of res's that are not compatible with my hardware, may be due to the kdm on my testing network) it is that after having used kdetv I can't login with out killing off the xserver.

That I am able to kill it off tells me that something is not right. Killed off = black screen no text. If I try to log back in before this black screen is achieved I get the scrolling display described above.

So I followed some instructions form http://forums.debian.net/viewtopic.php?t=26577.

So, how to modify xorg.conf to your needs? Here is it!
Say you want a resolution set to 1600x1200 at 75Hz, you use gtf tool to output a Modeline that'll be used in xorg later:

Code:

$ gtf 1600 1200 75 

  # 1600x1200 @ 75.00 Hz (GTF) hsync: 93.97 kHz; pclk: 205.99 MHz 
  Modeline "1600x1200_75.00"  205.99  1600 1720 1896 2192  1200 1201 1204 1253  -HSync +Vsync

Now, open your xorg.conf, then find Section "Monitor" then add those two lines as in the following -example- code:

Code:

Section "Monitor" 
   Identifier   "Configured Monitor" 
   Modeline   "1600x1200_75.00"  205.99  1600 1720 1896 2192  1200 1201 1204 1253  -HSync +Vsync 
   Option      "PreferredMode"      "1600x1200_75.00" 
EndSection

Then, find Section "Screen" and add this example code:

Code:

Section "Screen" 
   Identifier   "Default Screen" 
   Monitor      "Configured Monitor" 
   DefaultDepth   24 
   SubSection "Display" 
      Depth   24 
      Modes   "1600x1200_75.00" 
   EndSubSection 
EndSection

Be sure that Modes string is the same as above!

... And that's all? I hope so, let's save this file and restart your X server.

And I have success.

The res is set and login is not affected by kdetv's incompatibility with the new xorg.

I did try the suspend2disk again but that is still malfunctioning.

So is the bug in xorg or kdetv? Which group should I notify? Hope this helps someone.
