 Posted: Sat Jun 03, 2006 9:57 am Post subject: Xgl, Radeon 7500 and KDE without kdm |
 |
|
Hi all,
I followed the Xgl howto in the Gentoo wiki and was able to compile all necessary packages
without any problems (gcc 4.1).
But how can I manage to get Xgl working with my Radeon 7500 and without
usind kdm? Doing the "modify startx" stuff from the wiki?
I tried to do
| Code: | Xgl :1 -ac -accel glx:pbuffer -accel xv:pbuffer
LD_LIBRARY_PATH=/usr/lib/opengl/xorg-x11/lib/ DISPLAY=:1 compiz gconf
gconf-editor
|
but I get:
| Code: | Fatal server error:
Server is already active for display 1
If this server is no longer running, remove /tmp/.X1-lock
and start again.
|
Any ideas/help would be highly appreciated! Thanks!

You were right on with the modifying of the /usr/bin/startx script.
I mostly followed the wiki, but I haven't bothered to set up Xsession, so its a little bit different
1) Copy startx to a new file. For simplicity's sake, I copied it to /usr/bin/startxgl
2) edit the line in the new startxgl file that says
| Code: | | xinit $clientargs -- $serverargs -deferglyphs 16 & |
(its near the end of the file) to say
| Code: | | xinit $clientargs -- /usr/bin/Xgl -ac -accel xv:pbuffer -accel glx:pbuffer $serverargs -deferglyphs 16 & |
3) This is where I differ from the wiki, but I find it works just as well. Instead of using the wiki's compizrc script, I put the if statement into my .xinitrc, so it should look like the following
| Code: |
if [ `ps -A | grep Xgl | wc -l` == "1" ]; then
DISPLAY=:0 LD_LIBRARY_PATH=/usr/lib/opengl/xorg-x11/lib/ compiz --replace gconf &
sleep 1;
DISPLAY=:0 gnome-window-decorator &
fi
exec /usr/kde/3.5/bin/startkde
|
Now that you have modified these two files, you can simply type startx to start a normal X session, or startxgl to start an Xgl session.
I'm sure there is a much nicer way to do things with XSESSION in /etc/rc.conf , but I haven't gotten around to playing with that yet. |

Hi and thanks a lot for your explanations! 
With them I was finally able to start the Xgl server and get at
least a rough impression what's possible with Xgl.
Only a rough one because it's so _slow_...
Do you know if/and how it's possible to speed up things
a little bit and for example how I can disable the
shadows as I don't want them (I'm more interested in
the cool window behaviours *g)
Thanks!

I'd go out on a limb and say you have compiz-quinnstorm installed (Since it is acting slowly).
I've been seeing that on my machines with quinnstorm installed as well. My short term fix is to install compiz-vanilla. |

No, I'm already using compiz-vanilla... 
But as it seems the problem is the missing dri acceleration as
described here:

It would help to get direct rendering working.
EDIT: Xgl doesn't need direct rendering, since it uses mesa
Can you post your make.conf?

Thanks for your help offer! 
Well, as described in the other thread I got it working with the normal
x server by compiling by hand...
Should glxinfo also show that dri is enabled in Xgl or is it normal
behaviour that it says "no"?
Sure, I could post my make.conf but as its quite long which
part are you interested in? I would cut it out from the whole
file...

I'm looking for if you set VIDEO_CARDS variable in make.conf.
Xgl by default uses indirect rendering through mesa (from digging around in my configuration). I was thinking of normal Xorg at the time.
So therefore, glxinfo should report no on direct rendering when using Xgl
Also, post the output of |

Well, actually I've just read schmobag's posting and I've seen
that VIDEO_CARDS="radeon" is needed (which is probably why mesa
didn't compile any dri drivers). I only had vesa and fbgl before and
I'm compiling xf86-ati-drivers and mesa at the moment.
| Code: | emerge -pv mesa
These are the packages that would be merged, in order:
Calculating dependencies... done!
[ebuild R ] media-libs/mesa-6.5.1_alpha20060524 USE="3dnow mmx motif nptl sse -debug" VIDEO_CARDS="radeon* -i810 -mach64 -mga -none -r128 -s3virge -savage -sis -tdfx -trident -via" 0 kB [3]

I also read schmobag's post.
That is exactly where I was going with the make.conf and emerge -pv mesa. |

When the compile has finished I'll try and report again

OK, with VIDEO_CARDS="radeon" set in /etc/make.conf mesa compiles
the dri drivers, now... But nevertheless it still states that dri is disabled
if I start Xgl (and KDE) and it's still _very_ slow. Any ideas concerning this?

Are you using the latest xgl-coffee overlay?
if not, I'd set that up and then recompile cairo pango and gtk as described in the wiki. |

I'm using the portage-xgl overlay... For some reason the cairo ebuild is gone
since yesterday so I'm at least not able to compile the one from the overlay
(perhaps that's not necessary anymore?!). But I'll try to recompile pango
and gtk... Thanks!

I've recompiled cairo, pango and gtk+ but it's still very slow.
I'll have a look at the given url now... Thanks for that!
EDIT:
Seems as if the two overlays have become exactly the same in the meanwhile, I just checked out the recent
xgl-coffee tree but there's not a single difference to the portage-xgl one.

I've found something new in my Xorg.93.log:
| Code: | (II) RADEON(0): AGP card detected
drmOpenDevice: node name is /dev/dri/card0
drmOpenDevice: open result is -1, (No such device)
drmOpenDevice: open result is -1, (No such device)
drmOpenDevice: Open failed
drmOpenByBusid: Searching for BusID pci:0000:01:00.0
drmOpenDevice: node name is /dev/dri/card0
drmOpenDevice: open result is 8, (OK)
drmOpenByBusid: drmOpenMinor returns 8
drmOpenByBusid: drmGetBusid reports pci:0000:01:00.0
(II) RADEON(0): [dri] Found DRI library version 1.2.0 and kernel module version 1.22.0
(**) RADEON(0): AGP 4x mode is configured
(II) RADEON(0): AGP Fast Write disabled by default
(II) Loading sub module "shadowfb"
(II) LoadModule: "shadowfb"
(II) Loading /usr/lib/xorg/modules/libshadowfb.so
(II) Module shadowfb: vendor="X.Org Foundation"
compiled for 7.1.0, module version = 1.0.0
ABI class: X.Org ANSI C Emulation, version 0.3
(II) RADEON(0): Page flipping disabled
(II) RADEON(0): Will try to use DMA for Xv image transfers
(WW) RADEON(0): [dri] limiting video memory to one aperture of 131072K
(WW) RADEON(0): [dri] detected radeon kernel module version 1.22 but 1.23 or newer is required for full memory mapping.
(II) RADEON(0): Detected total video RAM=65536K, accessible=131072K (PCI BAR=262144K)
(--) RADEON(0): Mapped VideoRAM: 65536 kByte (64 bit DDR SDRAM)
(II) RADEON(0): Color tiling enabled by default |
Perhaps the (WW) are causing my speed problems? I'm using kernel version 2.6.16-gentoo-r8...
I've seen that x11-drm-20051223 seems to provide the radeon kernel module but as it's from
2005 I'd assume that the version from the kernel is newer, isn't it?
