ATI and fc5 dual head configuration.

mjlewis90 · #1 21st March 2006, 08:39 PM

hey all. i think i got a simple fix here but i dont know where it is!

i have a Dell Optiplex GX620 with 2GB RAM and 2 CPUs' running through a ATI X600/256MB vid card.
i'm able to get core5 up and running but i'm having problems getting X to use the dual head option correctly.
i have 2 dell 1905FP DVI monitors hooked to the DVI splitter cable going into the back of the box.

i can get both screens to work, and they span, but monitor 1 still clones monitor0 and "over-writes" the spanning desktop from monitor0. (strange... but i'm sure there's any easy fix).

i tried the gflrx drivers from ATI with no such luck. This is a simple config file but i'm not and expert on X!

Here is my xorg.conf file:

I have been f-ing with this for days now. I have ati mobility 200x that works great on ldc but not secondary display.

The only way I could fix this in fc4 was to use the ATI official drivers. Those currently do not support xorg 7.

If anyone can help him, it would help me too i think.

rdrever · #3 21st March 2006, 10:28 PM

I just got this working for my X800. I had the same problem as mjlewis90 where my second monitor cloned and overwrote. I fixed it by changing the BusID on VideoCard1 and specifying the MonitorLayout and CRT2Position options in the Device section. Even though I have 2 LCD's, the only way I could get it to work was to set one display as CRT and the other as TDMS in the MonitorLayout option. I have xinerama disabled, but it also works correctly with it enabled.

Here is my xorg.conf:

Thanks for the help, but when i did the CRT,TDMS options only the right side worked and it looked like it spanned too. we're on the right track, i'm wondering if the radeon driver is the problem. (strange option to get the dual head option to work).

torquato · #5 22nd March 2006, 05:55 PM

I have the same problem too. ATI 9000 configured with dual head and xinerama on, the second monitor shows a confused copy of the first one. Only the mouse pointer is displayed correctly and move from a screen to the other.

ATI driver doesn't resolve the problem. If i set colordepth to 8 it seems to work, not perfectly but work.

mjlewis90 · #6 22nd March 2006, 06:21 PM

thanks for the info... i tried the color depth to 8 and got 2 disktops with full mouse fuctions. this adds more fuctionality, but is not really a solution. i've turned Xinerama off until we can figure out a solution. i'm wondering if the radeon driver is the issue. i'm going to play with the vesa driver and see what happens.

thanks!

torquato · #7 22nd March 2006, 06:37 PM

I tried the solution of rdrever, it works but the expanded desktop is strange. When I expand a window it expands to both screens. This doesn't happen with FC4.

I'm agree that this isn't a solution, I'm waiting for new drivers that support xorg 7.

mjlewis90 · #8 22nd March 2006, 06:47 PM

tried the vesa drivers with no luck. i'm going to try the livna test fc5 ati drivers...

mjlewis90 · #9 22nd March 2006, 07:37 PM

doesnt look like the livna drivers will work either...

With this configuration everything works fine.
But I have the following problem: when I maximize a windows this expands to both screen or if I open a new window this is centered among both screens.
If I put Xinerama option off this problem disappear. When I maximize an application it expands in only one screen correctly.
I can't understand why, and I'd like to know If this is a problem or a property of Xinerama.

In FC4 by default Xinerama is Off or On? I never read my xorg.conf file...

That's all, it works!

My setup sounds like mjlewis90's setup, however adding

Quote:

Option "MonitorLayout" "TMDS, TMDS"
Option "CRT2Position" "RightOf"

and changing the BusID doesn't work for me. I have one graphics card an ATI Radeon X300 with a splitter for my dual monitors (two Dell 2405FPW). Changing the BusID for the second Device makes my second screen go blank as I would have expected it to. Is there something I am missing regarding changing the BusID for the second monitor even though I only have one graphics card with a splitter?

grimesp · #13 24th March 2006, 02:49 PM

Does anyone have an idea or estimate on when an ATI driver that supports X.Org 7 will be available? ATI releases a new driver about every month. Is the driver coming out in April going to support xorg 7?

pds · #14 25th March 2006, 03:24 AM

I have radeon working in dual head Xinerama mode but I would prefer to have dual heads working separately and of course this did work in FC4. If anyone knows the secret please post the xorg.conf or the needed changes. I've tried the ATI with FC4 but was not able to get this mode working.

domlayfield · #15 5th April 2006, 12:43 AM

Upon upgrade to FC5, I had the same problem as everyone else: dual-head on my ATI card was broken.

Thank God for this forum: I made the changes described by wjlewis90 and I'm back in action!

Thanks guys,

XOX DOM

Still none the wiser how they broke things, though. Don't understand why the X server has decided to ignore the information in the "SeverLayout" section...
