Radeon/KMS and KDE4

[flockmock]

Hello,
I am posting the first time here, so I apologize if that was mentioned already...

I activated KMS and compiled the git-versions of xorg-server, libdrm, mesa, xf86-input-ati (distribution: gentoo).

So far, all is fine, glxgears gives 1900fps (Radeon HD 4670) and I can play UT2004-demo without problems or graphical errors.

BUT: turning on the desktop effects does not work:
when using OpenGl the speed is so slow, that the system becomes unusable;
when using "XRender" I cannot use most of the effects, like snow or the desktop-switching-cube. It does not matter if I am using kernel 2.6.32.3 or a 2.6.33-rcX - problem is the same.

does anybody else experience similar problems and how do you solve it?
TIA

Some of the effects require OpenGL and won't work with XRender.

You should post your Xorg.0.log to a pastebin and link it here, the answer is probably in it.

grep -E "WW|EE" /var/log/Xorg.0.log

grep -E "WW|EE" /var/log/Xorg.0.log

ok, this is the result:
cat /var/log/Xorg.0.log | grep EE
Current Operating System: Linux brain 2.6.32.3 #2 SMP PREEMPT Thu Jan 7 18:41:19 CET 2010 x86_64
(WW) warning, (EE) error, (NI) not implemented, (??) unknown.
(II) Loading extension MIT-SCREEN-SAVER
(EE) Failed to load module "vesa" (module does not exist, 0)
(EE) Failed to load module "fbdev" (module does not exist, 0)
(EE) HID 046a:0050: failed to initialize for relative axes.


btw: I dont know if that has sth. to do with my problem, but running glxinfo with normal user rights, I get:

glxinfo
name of display: :0.0
display: :0 screen: 0
direct rendering: No (If you want to find out why, try setting LIBGL_DEBUG=verbose)
server glx vendor string: SGI
server glx version string: 1.2


... so direct rendering does not work? running it as root gives me:

name of display: :0.0
IRQ's not enabled, falling back to busy waits: 2 0
display: :0 screen: 0
direct rendering: Yes
server glx vendor string: SGI
server glx version string: 1.2

thx

For the "vesa" and "fbdev" errors, add "fbdev vesa" to VIDEO_CARDS in your /etc/make.conf. In other words, for the radeon driver you need:

VIDEO_CARDS="fbdev vesa radeon"

after that, do:

emerge -auDN world

(VIDEO_CARDS expands to USE flags so the emerge will pick up the changes.)

Sounds like you're not in the video-group. Try gpasswd -a <user> video.

thanks for the answers. the error messages after the suggestions from RealNC are now:

cat /var/log/Xorg.0.log | grep EE
Current Operating System: Linux brain 2.6.33-rc4 #5 SMP PREEMPT Wed Jan 13 21:36:22 CET 2010 x86_64

(II) Loading extension MIT-SCREEN-SAVER
(EE) open /dev/fb0: No such file or directory
(EE) HID 046a:0050: failed to initialize for relative axes.

all users are in the video group. still unbearable openGL performance. ..strange

Are you using an /etc/X11/xorg.conf file? Try using this:

Section "Device"
	Identifier  "HD4670"
	Driver      "radeon"
EndSection

and make sure the "Screen" section says:

Device "HD4670"

Also append this at the end:

Section "DRI"
	Mode         0666
EndSection

Also, please use http://pastebin.ca/ to post your entire /var/log/Xorg.0.log as well as the output of the "dmesg" command.

I changed the xorg.conf file according to your suggestions, no change.

my dmesg:

my /var/log/Xorg.0.log:

thx a lot!

Are you a member of the group that owns /dev/dri/card0 ?

seems you have a lot of old cruft in xorg.conf, get rid of it.
