Hi there.
I am willing to get a configuration that run correctly with my RADEON 9200 SE, on a KT266 VIA agp chipset. I own two screen : 19" (1600*1200) and a 17" (1024*768)
I first managed to get a dualhead configuration that worked (Xinerama). But the lack of DRI support get me angry so I started setting up a second server, with only one HEAD :
excerpts from /etc/x11/gdm/gdm.conf
| Code: |
[servers]
0=Monohead
1=Dualhead[server-Dualhead]
name=DualHead server
command=/usr/X11R6/bin/X -xf86config /etc/X11/XF86Config-4-dual -nolisten tcp -audit 0
flexible=true
[server-Monohead]
command=/usr/X11R6/bin/X -xf86config /etc/X11/XF86Config-4-mono -nolisten tcp -audit 0
|
Q : Is this a good Idea to get two X servers to start ?
Then I used fglrxconfig to get two configuration (mono/dual). In the meantime I lost the ability to run my old configuration... The left (17") screen appears "crypted", I thought it was due to VertRefresh or HorizSync but I didn"t managed to get it to work.
I used the "[url=https://forums.gentoo.org/viewtopic.php?t=102680"]Radeon Fglrx Howto[/url]"by spekulatius as reference.
So actually I have :
Kernel module AGPGART support
Two fglrxconfig XF86Config files
But I still have problems :
1- no_dri = yes option is needed to get XF86 to start
With "no_dri = no" I cannot manage to get X to get started. The server crash just after the RANDR extension started.
With no_dri = no, I manage to start but I can see thoses errors :
| Code: |
Symbol firegl_AGPAcquire from module /usr/X11R6/lib/modules/drivers/fglrx_drv.o is unresolved!
Symbol firegl_QueryHwCaps from module /usr/X11R6/lib/modules/drivers/fglrx_drv.o is unresolved!
Symbol firegl_AllocCache from module /usr/X11R6/lib/modules/drivers/fglrx_drv.o is unresolved!

I think that the DRI probleme isn't DUAL/MONO head related.
2- Dirty image on monohead server
The image is satured, colors are too bright so i get green zone were this is too bright...
I am not english speaking folk so I don't know oh to explain this. This never happend before...
3- Dual Head -> Two Right screens
I first get the old 17" screen "crypted" with the original XF86Config file produced by fglrxconfig. So I first changed the Monitor frequencies, but without sucess... I tried to change resolution (CTRL+ALT+num+) without success...
I allowed the "virtual" option, so I realized that the left monitor was a clone from the right screen !!!
I put my files on my server :
http://muposerver.dyndns.org/gentoo_files/XF86Config-4-dual
http://muposerver.dyndns.org/gentoo_files/XF86Config-4-mono
thanks.[/list] |

The mergedfb option on the standard ati driver will allow you to combine dual-head and direct rendering. It's an alternative to Xinerama. To use it, you'll need to use xfree-drm instead of ati-drivers, and I'm not sure how the 9200's work with that.
Anyway, it's an option. |

yep, you can run two or more xservers at the same time, but if i remember correctly only one xserver can use dri at a time. i think i read that here. i would assume the same is true for ati's fglrx driver cus i just tried running 2 xservers with 3d enabled and it crashed my system.
now i am talking about multiple xservers running using the same video card and monitor.
ie something like
| Code: | | X -xf86config XF86Config.nodri :0 vt08 |
from one vt, then pressing <ctrl><alt><f?> and running
| Code: | | X -xf86config XF86Config.nodri :1 vt09 |
now one xserver is running on vt8 and the other on vt9, but they are both using the same graphics card and monitor. (starting X like that is really useless. you won't be able to do anything. it's just an exaple that it will work and to try to explane what i'm talking about)
i think you can run 2 xservers at the same time using 2 different video cards... i seem to remember doing this in the past, but i'm not sure if it was 2 physical separate video card. the problem i had at the time was only one xserver would update the display at a time. for example lets say that...
monitor/graphics card #1 was being used by an xserver run on vt7
and
monitor/graphics card #2 was being used by an xserver run on vt8
when i hit <ctrl><alt><f8> monitor #1 would go black and monitor #2 would display stuff. if i then hit <ctrl><alt><f7> monitor #2 would go black and monitor #1 would display stuff.
i have no idea if things are still like that... but that's what i seem to remember from a while ago. from the link above i would say that things are no longer that way... but you may need to apply that kernel patch... i really don't know.
i'm gonna take a guess at what your want to do and give you a possible solution.
my guess is that you wanta use 2 monitors for working, but want 3d for games.
if that is the case you can run your xserver with xinerama and no dri. then when you wanta play a game run...
| Code: | | xinit /usr/local/bin/quake3-smp -set nosplash -- :1 -xf86config XF86Config.fglrx |
where the XF86Config.fglrx file has 3d enabled. so you just started another xserver on the next avalable vt. only one xserver is using dri or fglrx at a time so i think it sould be safe. i have done this with one video card and switching vt's did cause the colors in quake to go all funky. i can't see why it wouldn't work if one xserver was running with xinerama enabled... but i haven't done that myself.
(yes that code above was cut out of a script... well at least i don't run quake3 as my window manager any more.)
i hope something i said helped.
