This method sounds interesting, but I have some doubts. Won't two
separate X servers be too big challenge for my box? I've got an Athlon
XP 3000+ (working at 2167 MHz) plus a GB of RAM. Having Xgl loaded in
the background could be deadly for performance in OpenGL apps on Xorg.
Please correct me if I'm wrong.

Actually, I haven't though about it. I've got an ATI Radeon 9600XT
running on proprietary drivers (emerged ati-drivers). It works fine, as
long as you can tell that Radeon works fine on Linux; I haven't got any
experience with NVidia's hardware. Returning to the topic, I haven't got
an idea neither whether Aiglx works with my Radeon nor why I'm not using
Aiglx. When I've started to play with fancy 3D servers I was using
Debian, and I found an article describing quite precisely how to get Xgl
running on unstable Debian. Worked fine, so I've found Xgl a nice
choice. Am I mistaken?

Thanks for your feedback,

I run it on my laptop and have absolutely no problems, the xserver alone won't 
kill your performance.

well, I played ut2004 on my amd64 3200+/gf6600. One instance of Xgl one with 
naked X (and a xterm). Worked well enough.

I don't know which drivers support AIGLX, but with aiglx (or nvidia), you can 
go from eye-candy-to-fast-to-eye-candy with two mouseclicks. (start 
beryl-manager, choose beryl from the menu for eye candy or your other wm, for 
speed).

I managed to launch two X servers at one time, however I'm still far
from being successful. My /usr/share/gdm/defaults.conf

<snip>

[servers]
0=Standard
1=Xgl

[server-Standard]
name=Standard server
command=/usr/bin/X -audit 0
priority=0

[server-Xgl]
name=Xgl
command=/usr/bin/Xgl :1 -ac -accel glx:pbuffer -accel xv:pbuffer
flexible=true
chooser=false
handled=true
priority=0

<snip>

When entering default runlevel GDM starts and launches both servers.
First one, Standard, has got direct rendering turned on and OpenGL is
rendered by fglrx driver. OpenGL apps work fine. On the other hand
second server, Xgl, has not got direct rendering, and what is most
suspicious, it uses Mesa drivers, which cause Beryl to run at an
absolutely unacceptable performance. Why both servers are not rendered
using fglrx? Have you got any ideas how to do it?

Jan

Have you checked your /var/log/Xorg.*.log files?  They should reflect
why the Xgl server is not being accellerated.

Also, one other option may be to try the opensource radeon driver.
You can lookup your card's pci ID (use lspci && lspci -n) in
/usr/src/linux/drivers/char/drm/drm_pciids.h to see if it is supported
or not.  If so, you should be able to get aiglx working with
opensource drivers.

Got it! Somewhere around 92% of /var/log/Xorg.94.log, which is logging
Xgl, I've found:

(EE) fglrx(0): Hardware has already been locked.
(II) fglrx(0): [drm] removed 1 reserved context for kernel
(II) fglrx(0): [drm] unmapping 8192 bytes of SAREA 0x2000 at 0xb7f7b000
(WW) fglrx(0): ***********************************************
(WW) fglrx(0): * DRI initialization failed!                  *
(WW) fglrx(0): * (maybe driver kernel module missing or bad) *
(WW) fglrx(0): * 2D acceleraton available (MMIO)             *
(WW) fglrx(0): * no 3D acceleration available                *
(WW) fglrx(0): ********************************************* *

Hardware's locked? Do they mean that I can render only one X server
simultaneously? They must be kidding...

And near the end of this file:

(EE) AIGLX: Screen 0 is not DRI capable

No doubt about it.

What's also interesting at the 96th per cent of Xorg.0.log, standard
server's log, I've got:

(EE) AIGLX error: dlopen of /usr/lib/dri/fglrx_dri.so failed
(/usr/lib/dri/fglrx_dri.so: cannot open shared object file: No such file
or directory)
(EE) AIGLX: reverting to software rendering

Did portage forgotten about something while emerging ati-drivers? Or
maybe it's my mistake to force AIGLX to start ('Option  "AIGLX" "true"'
in xorg.conf)?

Found it. In the section radeon_PCI_IDS I've found the following line:

{0x1002, 0x4152, PCI_ANY_ID, PCI_ANY_ID, 0, 0, CHIP_RV350}, \

Please verify my plan. I should recompile my kernel with device drivers
-> character devices -> radeon built in (or as a module) and in
xorg.conf set driver to "radeon". Am I right?

Thanks for your feedback,
Jan

Try searching dmesg for drm.  My guess is either the radeonfb module
is conflicting, or the fglrx module.

In fact the  radeon module conflicts with fglrx. I've unloaded fglrx, 
modprobed radeon (verified by lsmod) and relaunched gdm. But it's still 
refusing to use the new module:

(EE) Failed to load module "radeon" (module does not exist, 0)

Actually it does exist, it is loaded and besides listed in xorg.conf to 
be bound to my Radeon 9600XT. I'm can't get it. Any suggestions?

Thankful for your support so far and still asking for help, sincerely yours,

Did you try remerging xorg with the radeon VIDEO_DEVICE flag after you removed 
the fglrx module?

Actually I haven't heard about this flag. I've just googled for it but
without any reasonably results. Could you tell me more about it or send
me a link to a proper website which could enlighten me?

I visited gentoo.org and skimmed the documentation. What I've read
doesn't make me cheerful at all. Quoting from
http://www.gentoo.org/doc/en/ati-faq.xml :

GPU             Common Name          Support
<snip>
R300,R400,R500  Radeon 9500 - x800   xorg 2D, ATI DRI

If I understand it correctly, this means that if I want a 3D
acceleration I've got to use closed ATI's fglrx, and if I'd like to have
an open driver from Xorg I am forced to accept 2D only. So no fglrx is
no 3D at all. Please tell me that I'm mistaken.

No, there is constant development on the R300 front.  What versions 
of Mesa, x11-drm, and libdrm do you have installed?

For which apps run for sure with 3D accel on an R300 see:

  http://dri.freedesktop.org/wiki/R300Application

For more info and configuration see:

[Jan Stępień]

[-- Attachment #1: Type: text/plain, Size: 1073 bytes --]

As far as I can see there is no chance neither to get my Radeon to
cooperate with open source driver nor to turn on AIGLX with my fglrx, at
least at the moment of writing. It's a pity, but allow me then to return
to the secondary topic of this thread.

Is it possible to enable some kind of a chooser which would allow me to
choose whether I'd like to launch Xgl or Xorg? While working on my
/usr/share/gdm/default.conf I've spotted a server called 'chooser'.
Could you tell me what is this server doing and could it be a solution
for my problem?

Of course the choice doesn't have to be done in GDM. It could be a tiny
bash script or a simple C++ application run in the default runlevel
which would ask me for pressing a specific key to run Xorg - otherwise
it will run Xgl - for example changing the line "0=Standard" in the file
I've mentioned above. Have you got ideas or do I have to write such an
app by myself?

A "chooser" in the GDM/XDMCP sense is a program that lists available
hosts to log into (via XDMCP).

I'm not aware of any program that will allow you to choose between X
servers any more than I'm aware of a program that will allow you to pick
MTAs.  The simplest solution is to just pick one.  Why would you want to
bounce back and forth between X servers?

Why should you need to write anything.  Forget GDM and if you want to
run X then type "X [ENTER]".  If you want Xgl then "Xgl [ENTER]".  But
again, why would you want to complicate your life with 2 different X
servers?

I've begun this thread because of my difficulties with running some
OpenGL applications, e.g. Americas Army, on my Xgl. If you'd like to
read any details you can take a look at first posts of this topic.

Then you probably don't want to use GDM or any other DM as they are
primarily designed to "manage" displays that are already selected.  What
you want is more of a chicken-and-egg issue for a display manager.

What you likely need is something to be run from the command line (i.e.
*before* X is started).  startx (or xinit) are perfect for this.  No
need to write any fancy program, it can pretty much do what you're
asking:

$ startx /path/to/program/that/needs/X.org -- /usr/bin/X
$ startx -- /usr/bin/Xgl

or whatever. There's probably a dozen other ways to do it.  See the
startx man page for details.

Thanks, I'll take a look at the manual and give it a shot.

You may choose to start X or Xgl generic way using startx or startxgl scripts. 
Out there are some.

Thanks, now it works flawlessly. I can easily launch a slick desktop
with Xgl and Beryl, and if I require direct rendering I simply log out
and launch Xorg.

Now I'll try to find a clever solution and make this method a little bit
more automatic. We'll see what I'll be able to find around the web.

Thanks once again.

Jan Stępień

I reckon most in America's army would love to have your problems.

I use a workaround to accomplish something similar. You'll have to adapt 
it as I use startx not a display manager. I have two ServerLayout 
sections in xorg.conf (RADEON and FGLRX), and xinit takes a -layout 
argument to choose between them. Like this:

startx -- -layout RADEON

The -- is required so that startx won't try and process the following 
arguments, but rather pass them through to xinit.

Hmm, can you post your current xorg.conf and dmesg outputs?

Hmm, looks like kernel DRM is still having some issues.

Try changing your xorg.conf back to Driver "radeon", comment out the
"Option" lines, and then do a full reboot.  You might want to
"rc-update -d xdm" before this so that you boot into a console, and
can then try things with a plain old "startx".

HTH,

Okay, this might not, be helpful but I just want to do a sanity check here:  

1. Check your xorg.log and make sure you are using the xorg.conf you think 
you are.

2. Make sure the required kernel module is in place.  It can be loaded by 
modprobe and that action confirmed by lsmod.  It will be somewhere 
under /lib/modules (sounds like you've already done this).

3. Make sure you aren't confusing a kernel module/driver with a X11 driver.  
Generally the later depends on the former, but they are provided by 
different packages and located differently on the filesystem -- and 
generally kernel modules are not listed by name in xorg.conf.

IIRC, this is the kernel module required for DRI with the in-tree, libre 
drivers for ATI hardware.  The matching x11-driver is "ati" or "radeon".

which indicates that you are attempting to use the fglrx x11-driver, and 
not the radeon x11-driver.

If you use the CONFIG_RADEON_DRM kernel module, you also need to use 
the "ati" or "radeon" x11 driver.  If your use the fglrx out-of-tree, 
esclavitud kernel module (at least I think there's a kernel module by this 
name) you'll alsa need to use the "fglrx" x11 driver.

You seem to be running into a simple misconfiguration at this point.

I'm sorry, I've forgotten to modify this line while attaching xorg.conf.
When I was trying to launch Xorg with radeon driver I obviously
commented out the "fglrx" driver and uncommented "radeon" driver's line
- inversely to what I have actually attached. So it should be:

>         Driver      "radeon"
> #       Driver      "fglrx"

And to make it even more precise - while entering default init level
fglrx is NOT loaded and radeon is loaded.

Jan

I'm no expert, but as far as I know, that's the reason why AIGLX
succeeded Xgl. So if you ask me, I think AIGLX (if it works with ATI)
would be the solution to your problem.

Fair enough. Firstly I'll check whether AIGLX will be working with my
video card, and in case of failure I'll give xlaunch a shot.

I've reemerged Xorg adding "aiglx" to USE variable, modified
/etc/X11/xorg.conf (actually I've been following these instructions:
http://gentoo-wiki.com/HOWTO_AIGLX) and tried to launch Xorg with AIGLX.
Unfortunately efforts were fruitless. Accordingly to article mentioned
above I have to enable composite in xorg.conf:

Section "Extensions"
        Option         "Composite"   "Enable"
EndSection

After launching X server with this setting it results in using Mesa
instead of fglrx, which means NO direct rendering, as proved by glxinfo.
Beryl cannot be launched because of lack of DRI.

If I turn composite off, the X server is driven by fglrx, which gives me
direct rendering and Beryl's refusal to start because of lack of
composite extension.

It's all quite suspicious, taking into account fact that Radeons are
listed at the website above as video cards able of running AIGLX. But
maybe only on FOSS drivers...?

Afterwards I've downloaded xlaunch. When trying to launch an app (in
this case armyops) starting xlaunch in a terminal in an existing X
server the screen blacks out, probably trying to launch new X session
and suddenly restarts GDM, meanwhile killing my original session.

I've also tried to use xlaunch in a text console having my previous X
server turned on. Results are the same.

Have you got any suggestions?

Best regards,
Jan Stępień

Sounds like you are out of luck. The open drivers with AIGLX support don't 
support your card and the closed ones don't support AIGLX.

So your only hope: Xgl and a second X. That is a little bit sad. Send 
your 'thank yous' to ATI.

It might be a proprietary drive issue. I use an intel chipset - composite on, 
direct rendering, AIGLX and Beryl all working together. Just as the wiki 
tells you to do.

Try turning off GDM, logging in via console and then running startx. Then from 
inside that xserver use xlaunch to start the game, see if the results are any 
different. Xlaunch works perfectly for me from within KDE or enlightenment, 
although I've never had GDM running (or even installed) on this machine.

[gentoo-user] Xgl and direct rendering or 'Would you like Xorg or Xgl, sir?'

[Jan Stępień]

[-- Attachment #1: Type: text/plain, Size: 2078 bytes --]

Hi everyone,

I've been using Xgl for quite a long time without any serious problems.
Recently I've tried to launch America's Army (emerged one, version
2.5.0) on my box, but...

~ armyops
Xlib:  extension "XFree86-DRI" missing on display ":1.0".
Cheat protection disabled
open /dev/[sound/]mixer: No such file or directory
WARNING: ALC_EXT_capture is subject to change!
Either GL_EXT_bgra or glDrawRangeElements not supported- bailing out.
History:
Exiting due to error

Being quite disappointed I verified the first line of the output above
with glxinfo. And so...

~ glxinfo
name of display: :1.0
Xlib:  extension "XFree86-DRI" missing on display ":1.0".
display: :1  screen: 0
direct rendering: No
<snip>

It sounds rather unbelievably. I've got running Xgl with Beryl's
dazzling animations and I'm informed that despite having over 4000 FPS
on glxgears I have not got direct rendering. What the...?

Few days later I've accidentally launched Xorg (using startx script)
instead of my Xgl. When I entered my old, two-dimension desktop I
thought that trying America's Army over here, without Xgl, could tell me
something more (i.e. that something's wrong with my configuration or
whatever else). So I typed armyops in the terminal... And surprisingly
enough the game has started. Furthermore, the framerate was quite
satisfactory.

After this quite long introduction I'll finally get to the point. I have
got two questions.

1. Is it possible to enable somehow direct rendering on Xgl, therefore
allowing OpenGL apps to work as ought to.

2. If the answer to the first questions is "NO", then is there a method
of choosing which Xserver to use? Can I choose whether I'd like to
launch Xorg or Xgl? Or maybe I can even enable such choice in GDM login
screen?

If you need any further information regarding by box please don't
hesitate to ask. Any support would be highly appreciated.

Best regards,
Jan Stępień

glxgears is not a benchmark.
it might be unbelievable, but it is true. If you use Xgl, no direct rendering 
there.

nope. It isn't.
Xgl and direct rendering are exclusive. One or the other.

Yes. 

Or you can start a second X with xinit. So you would have one desktop (on F7) 
with Xgl and one (F8) with 'normal' X.

Any reason, you are using Xgl? No Aiglx with your card?
