Beryl kubuntu

trebek · 02-26-2007, 02:53 AM

Hello, i got kubuntu running on a toshiba laptop that has an "ATI Technologies, Inc. Radeon Mobility 9100 U3 (R200 IGP)". I've been following the following instructions to install beryl:
http://wiki.beryl-project.org/wiki/I...o_Acceleration
https://help.ubuntu.com/ubuntu/deskt.../hardware.html

Now, as a regular user, from the command 'glxinfo | grep rendering', i get:
direct rendering: No
As root, i get:
Error: unable to open display (null)

I completed the tasks there in the hardware link, with no errors displayed, restarted the machine, and i don't get that yes to appear. What's missing here? Is my machine or video card not beryl capable?

Radeon should be fine with Beryl, but getting DRI enabled is another matter. You need to make sure there is a section for DRI (which sets a correct mode) in your /etc/X11/xorg.conf, that you have correct modules loaded there, that the driver is actually in use (again the same file) and so on..there are numerous things that can prevent DRI from starting. One thing is that it won't work (with ATI cards at least) if Compiz is enabled, and it might well be enabled in Kubuntu; that means you'll have to manually disable it. I think there are a whole lot better guides/howtos on the web that I can write here, about getting DRI working with ATI cards, so go ahead and search -- they should be easy to find. The thing depends a lot on the kernel, X and distribution you use; sometimes even the best advices don't solve problems. Last time I dealt with a mobility radeon and ATI's fglrx drivers I had to install them (from the Ubuntu reposity; ATI's official installer didn't do the trick -- Ubuntu's .deb did some alterations to system config after the actual driver install that would otherwise have to be done manually to get the thing working), then manually disable Compiz, tell X to load a module that wasn't loaded by default (can't remember which, but it's in the howtos on the web, and depends on your distribution/X if it is there already), restart the machine (for some reason restarting X wasn't enough) and only then got it working. Must say that before it was at this point, I had worked on the matter for two days, first didn't get DRI working, then I did get DRI working but with MESA drivers and not ATI's fglrx...

It's complicated at the moment, I'm afraid. ATI's drivers aren't the easiest to install, or get working after they've been installed, and the whole DRI stuff -- especially when added to Beryl/other OpenGL desktops -- is a difficult piece if it doesn't work all right for some magical reason the first time. I've installed it on some machines in less than two minutes just by installing some binary packages and rebooting, and spent days with other machines tweaking X and Beryl manually to get it running. And one laptop just refused to work with it, even running 'glxinfo' resulted in X crashing.

So..good luck

ATI's drivers don't really work well, since to use Beryl with AIGLX (which is the best option) "Composite" has to be enabled in your xorg.conf file. Only problem is, ATI's drivers don't support Comosite. I finally got the fglrx drivers to install and work, then had to remove them and use mesa's DRI driver for my card (Worked better anyhow) to get Beryl running. The only real feature the fglrx drivers had to offer that I miss is the TV-out.

That sounds really out of reach. But hey, i'll be giving it a try eventually, patiently. I'll let you guys now in detail what i do. Gotta write down and document every step i perform, that works of course, so that other people like me don't have that hard a time as i am going to. Jajajaja. LOL.

Thanks dudes, LQ rules.

Just a word of caution in case you don't already know. Back up your xorg.conf file before making any changes at all. It'll bite you in the @$$ if you don't.

Yeah man, i know, i already did. Now, here are other steps i took to install this fglrx thing. I got everything down without problems, but when restarting the machine, it stalls instead of displaying the logon screen. The hard drive light turns off and stops blinking, and i just see a blue kubuntu logo as nothing happens.

1. Enabled the restricted repositories.
2. Disabled composite Extension:

Code:

Section "Extensions"
        Option  "Composite" "Disable"
EndSection

Section "ServerFlags"
        Option  "AIGLX" "off"
EndSection

3. Install:

Code:

sudo apt-get update
sudo apt-get install linux-restricted-modules-$(uname -r) #Okay if it is already installed
sudo apt-get install xorg-driver-fglrx

4. Configured the driver:
Change ati for fglrx in the Device Section of /etc/X11/xorg.conf
sudo aticonfig --overlay-type=Xv
5. Restarted the machine.

Here's the link!!!

After the restart, that's where the computer stalls.

Help me get this beryl going please!!!!! LOL ROTGL

Hey there guys.

I just upgraded to feisty fawn and i got the 'direct rendering = yes' message, but i got an extra line that i don't know the meaning of it. Here's the entire message:

Code:

libGL warning: 3D driver claims to not support visual 0x4b
direct rendering: Yes

Just in case, i had to uninstall and install xserver again after the upgrade, because somehow x didn't load even when putting the original xorg.conf file. If you tell me that that line there doesn't matter, i'll take your word for it and start the latter steps to get beryl working.

Thanks in advanced for the help.

That line doesn't matter. At least for getting beryl running. It has something to do with the Open source ati driver. I get the same thing and Beryl runs just fine. I believe it is saying that the driver does not support 32-bit color. "visual 0x4b" corresponds to this line in "glxinfo":

Code:

0x4b 32 tc  0 32  0 r  .  .  8  8  8  8  0  0  0  0  0  0  0  0 0 Ncon

which specifies 32-bit color depth. All this is saying is that the driver doesn't seem to support it. Not really a problem for this, so just use 24-bit color.

You would not believe what just happened to me, so have a look at this. I typed the following command just like the manual says, and this is the output:

:~$ sudo apt-get install beryl emerald-themes
Reading package lists... Done
Building dependency tree... Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable

The following information may help to resolve the situation:

What the hell does openoffice have to do with beryl??? I mean, i am just following instructions, and the first step worked fine (sudo apt-get install xserver-xgl).
