(WW) I810(0): Direct rendering disabled

[npaisnel]

On my other post about screen resolution changing, SheeEttin, noticed that I have Direct rendering disabled.
He also said to come back when I want to enable it.
What actually is it, what difference will it make? and how do I go about enabling it

Thanks

Neil

Re: (WW) I810(0): Direct rendering disabled

Direct rendering is basically rendering done by your video card, as opposed to your CPU.
Because this is onboard video/proprietary video card, it'll take a few steps.
First, edit /etc/X11/xorg.conf as root ("kdesu kate /etc/X11/xorg.conf"). Find the "modules" section, and make sure one line reads Load "dri". Then, below that section, paste this:

Section "Extensions"
 option "Composite" "false"
EndSection

Section "ServerFlags"
 option "AIGLX" "off"
EndSection

Then reboot, and paste/post the results of "cat /var/log/Xorg.0.log | grep EE && cat /var/log/Xorg.0.log | grep WW".

Kate cam up with xorg.conf, but the konsole window also came up with this error:

neil@Feisty:~$ kdesu kate /etc/X11/xorg.conf
DCOPClient::attachInternal. Attach failed Could not open network socket
kbuildsycoca running...

What is that all about?

Anyhow back to the job in question

Load "dri" was already there, have added the section and this was the xorg.conf section with regard to the screen:
Section "Screen"
Identifier "Default Screen"
Device "Intel Corporation 82815 CGC [Chipset Graphics Controller]"
Monitor "DELL E151FPb"
DefaultDepth 24
SubSection "Display"
depth 24
virtual 1280 960
modes "1024x768@60" "1280x960@60" "1024x768@70" "1024x768@75" "832x624@75" "800x600@60" "800x600@75" "800x600@72" "800x600@56" "640x480@75" "640x480@72" "640x480@60"
EndSubSection
EndSection

and here is the result :

neil@Feisty:~$ cat /var/log/Xorg.0.log | grep EE && cat /var/log/Xorg.0.log | grep WW

Re: (WW) I810(0): Direct rendering disabled

You sure you put in the line about AIGLX? That should've turned it off... If you did, try changing the "off" to a zero.
If that doesn't work, try removing the Load "dri" line. I actually don't have it for some reason, but direct rendering works.

Re: (WW) I810(0): Direct rendering disabled

Yep, AIGLX line there, it was copied and pasted direct from your post.

Tried changing the off to 0 no luck

removed the Load dri line and this is the result

neil@Feisty:~$ cat /var/log/Xorg.0.log | grep EE && cat /var/log/Xorg.0.log | grep WW
(WW) warning, (EE) error, (NI) not implemented, (??) unknown.
(II) Loading extension MIT-SCREEN-SAVER

Re: (WW) I810(0): Direct rendering disabled

Well isn't that interesting.
It may be that it truly is not DRI capable, but I'm not sure. (Be advised that I'm handling this as if you had an ATI or nVidia card in there.)

I guess one thing to do would be "glxinfo | grep direct". Post that. (Oh, and don't forget to put the DRI line back in.)

Ah! You're still using the vesa driver, aren't you! Change the driver to i810.

[npaisnel]

Re: (WW) I810(0): Direct rendering disabled

Changed to i810 in xorg conf utility and put Load "dri" back in


neil@Feisty:~$ glxinfo | grep direct
direct rendering: No
OpenGL renderer string: Mesa GLX Indirect
neil@Feisty:~$


So seems it is not possible?

EDIT

Just found this:

Typically, the amount of dedicated memory used by the video card is autodetected by the X server, but some integrated video chips (such as the Intel i810) have little or no video memory of their own, and instead borrow main system memory for their needs.

Re: (WW) I810(0): Direct rendering disabled

Also, when I ope KATE from the konsole window to edit xorg.conf, the konsole window shows this error:


X Error: BadDevice, invalid or uninitialized input device 167
Major opcode: 144
Minor opcode: 3
Resource id: 0x0
Failed to open device

Does that have any bearing on this?

Re: (WW) I810(0): Direct rendering disabled

Nah, that probably comes from having wacom tablet devices in xorg.conf. Feel free to remove them (if you don't have a wacom tablet, of course).

Well, if I had to guess, I'd say that you really can't run direct rendering with that chipset.
I suggest poking around (try Google, something like "intel i810 direct rendering") to see if it is or isn't possible.

Re: (WW) I810(0): Direct rendering disabled

I had removed them, but running the xorg config util, brought them back.

Cheers for your help.
Wiki mentions driver written for i810 for dri so, i'll just have to keep searching

Thanks for all your help
