Posted: Thu Oct 20, 2005 12:59 pm Post subject: Kernel 2.6.13+xorg 6.8.x+nVidia+Translucency mini-Howto |
|
|
DISCLAIMER: I noticed that a few people had problems with getting xorg working after upgrading to the 2.6.13 (especially nVidia card owners). This one is geared towards who want translucency support in xorg 6.8.x Sorry if I duplicated someone else' posts...
First things first, I have managed to get translucency working yesterday in KDE. Unfortunately it took me a few hours to get it there. After a fair bit of searching and experimenting I got it to work. My own system has the following:
- nvidia-kernel 1.0.6629-r4
- nvidia-glx 1.0.6629-r6
- xorg-x11 6.8.2-r4
- KDE 3.4.1 (meta-install too
)
- udev-070 (udev-only)
Kernel 2.6.13 + xorg 6.8.x + nVidia
After upgrading to the new gentoo-sources kernel (2.6.13-gentoo-r3), xorg refuses to use the stable nvidia driver. There are two ways around that issue:
- upgrade to nvidia-kernel/nvidia-glx (version 1.0.7676)
- staying with the older version (1.0.6629) but a bit of hacking.
To stay with the older version you need to recreate the /dev/nvidia0, and /dev/nvidiactl devices. For some reasons they don't get created by udev. There is a bug report already up here.
Currently a good work around is to insert this line into /etc/conf.d/local.start:
| Code: | | /sbin/NVmakedevices.sh |
nvidia-kernel 1.0.7xxx Issues
You can get translucency working in the 1.0.7xxx nvidia drivers. But since the 2D rendering acceleration is broken. So translucency will be extremely slow.
Translucency + xorg 6.8.x
Translucency is fairly easy to get running under KDE 3.4.x, as it has a built-in engine. Otherwise you will need to use
xcompmgr. To get translucency support in xorg you need to add the following section into /etc/X11/xorg.conf:
| Code: |
Section "Extensions"
Option "Composite" "Enable" # For nvidia-kernel 1.0.6.xxx
Option "RENDER" "Enable" # Not needed by nVidia cards. ;-)
EndSection
|
nvidia only
To get translucency running you need to add the following lines to your Device section:
Option "AllowGLXWithComposite" "1"
To speed things up (WARNING GeForce4x or lower users!!! DO NOT USE IN 1.0.7xxx. YOUR SYSTEM MAY CRASH!):
Option "RenderAccel" "1"
Conclusion
Now you have eye-candy galore with 6.8.x translucency!
References
Here are a few great references that helped me out:

I'm using 1.0.7676 with 2.6.13-gentoo-r3 on an FX 5700 using composite (translucency etc) and Option "RenderAccel" "1" doesn't crash here. Maybe I'm lucky - no problems, not even the udev issue. I'm also using xorg 7.0 rc1... that could be the difference maybe. |

As a remark, on my amd64 machine 1.0.7676 is not creating devices as well (and I saw other reports from amd64 architecture on that). So it does not look like upgrading to 7676 will necessarily resolve the need for manual device creation. |

don't know if you're a lucky guy:-) I had the described issues with a GF 4200Ti since I replaced it with a 6800GT I've no problems using composite with the 1.0.7676 driver. I some forum I read that this problems are limited to GF4 or earlier cards...

One problem with this approach, if you use xdm/gdm/kdm, there is a *very* good chance that this script won't create the devices in time for {x,g,k}dm to start in time. In my case, I created my own init script which creates the devices, and I have /etc/init.d/xdm 'need' it, or perhaps call /sbin/NVmakedevices.sh from the start() portion of the xdm init script.
I'm almost wondering, given the number of nvidia users out there, if there doesn't need to be some kind of "official" support in the init scripts. Perhaps have a flag in /etc/rc.conf like "NVIDIA=yes", and then a test in /etc/init.d/xdm to ensure that (a) the NVIDIA flag is set, and (b) the /dev/nvidia* files don't exist, then create the devices manually.
In any case, good work deepwave.
Andrew. |

Something like that has to be done (really, the best would be to revert to the old sysfs behaviour, in my opinion)
Delegating device creating to /etc/init.d/xdm seems indeed neater than to have a separate /etc/init.d/nvidia script, but will leave in a cold people which start X with startx.
But I'm would be worried more non-GPL drivers will appear (are there binary-only drivers for USB devices ?), and we'll have to maintain a parallel to udev system to accomodate them |

When I maximise and restore windows X fails to repaint the screen leaving it looking like a mess, until something is moved over that area again and its repainted correctly.
Heres a screenshot of which should be showing firefox maximised, but its only repainted the top left of the window...
[img=http://img484.imageshack.us/img484/6682/xorgfailsrepaint2qt.th.png]
Does any one else get this? Any idea how to fix that problem? |

My renderaccell seems fine, xcompmgr tested for 1 hour with client-side shadows and translucency on, goin lots faster of what I

But kde 3.5 options doesn't seems to work there, I'm wondering if xcompmgr need to be loaded for kde options to work... ??!?
EDIT: could also be my renderaccell (retested and some apps are not fine-updating), I don't know how to test.
in xorg.0.log renderaccel seems fine but I get, at the end of the file,:

try running xcompmgr -FncC and see how stable your machine is

everything is working great and stable here:

kernel 2.6.13-r4-gentoo
nvidia driver 1.0.7676
xorg-x11 6.8.99.15-r4

Just after playing games (Doom3) the shadows are gone and I've to restart xcompmgr...

Is fairly stable, also by rendering transparent my firefox window (using gtk-engines-qt to
match linspire clear QT theme), I played with it for about 20 minutes, it gaved me this output:
| Code: |
error 3 request 158 minor 6 serial 42879
error 9 request 156 minor 4 serial 42880
error 4 request 54 minor 0 serial 43024
|
but no crash or misfuncioning (other than tooltips transition that are skipping intermediate frames).
Still, kde transparency not working. _________________ Every day a new distro comes to birth. Every day a distro "eats" another.

Thanks for the tips. I had played with this before, but I didn't know about AllowGLXWithComposites and RenderAccel so it was not really usable. It's now working great with no noticable slowdown. I'm using KDE translucency with:
AMD64 3000 w/ gforce 6800
nvidia-kernel (and glx) 1.0.6629-r4
kernel 2.6.13-gentoo-r3
xorg-x11 6.8.2-r1
kde-meta 3.4.1
There is one minor annoyance though: the kicker panel is getting treated like an inactive window, so it is always shaded. I can't seem to find away around this behavior. Does anybody have any ideas?
EDIT: It turns out that the "Dock Windows" setting does control the kicker panel translucency, but you won't see the effects until you start a new session. So the minor annoyance is solved.

Does the latest version of kde have any fixes for this? I'm still running kde 3.4.0 but even trying xcompmgr gives me the same dodgy repainting problems.
http://img484.imageshack.us/my.php?image=xorgfailsrepaint2qt.png
I'm running...
kernel 2.6.13-gentoo-r2
xorg-x11 6.8.99.15-r4 (also tried 6.8.2-r4)
I have a geforce 6800 gt running...
nvidia-glx-1.0.7676-r1 (also tried 1.0.6629-r6)
nvidia-kernel-1.0.7676 (also tried 1.0.6629-r4)
Any ideas? any one else get this problem?
When I run kde with all the eye candy on its very stable, haven't managed to crash it - but its totally useless when half the screen fails to repaint all the time  |

| I didn't notice it before, but I'm getting the same problem. It only happens when I maximize a window. If you grab the titlebar and move the window around, it will suddenly fix itself. I don't really know much about how this works, so I'm not sure whether to point the finger at KDE or X or Nvidia or something else. |

I have not tried xcompmgr myself, but occassionally I get things like that under KDE 3.4.1
I think this is an issue with the KDE translucency engine. Few other things I have noticed:
- some SDL programs have issues with display (missing titlebars or in the case of rocksndiamonds not appearing).
- GTK apps that repaint often (like gkrellm2 or XMMS when it is playing), produce flickers when running OpenGL apps in full screen.
Again I don't know if it is just me or KDE or XOrg. _________________ Current open source project: justCheckers, a cross-platform checkers suite. |

The fail-to-repaint problem was solved for me after upgrading KDE to 3.5_beta2!
I'm running xorg-x11 7.0 RC1 on two systems: one with an Ati card (using EXA drivers), one with nvidia (using closed source drivers). Both computers run well with composite and kompmgr. The repaint issue disappeard for me and I'm 99% sure it was a KDE bug. _________________ Alle dingen moeten onzin zijn. |

I'm running xorg-x11 7.0 RC1 on two systems: one with an Ati card (using EXA drivers), one with nvidia (using closed source drivers). Both computers run well with composite and kompmgr. The repaint issue disappeard for me and I'm 99% sure it was a KDE bug. |
Brilliant, final release of kde 3.5 shouldn't be too far off so I'll wait till its out and hope it fixes the problem for me as well
"xorg-x11 7.0 RC1" I assume thats the modular X? |

P.S.: my tansparency issues were caused by kde-3.5_beta2, seems that I had some bug in the connection between the GUI configurator
and the real options..... _________________ Every day a new distro comes to birth. Every day a distro "eats" another.
