Dell Studio 1555: ati 4570

hi to everyone,
i read everything about that video card on internet about my 2d problems, i mean: i have all packages upgraded few minutes ago (so xorg is 1.7 and kernel is 2.6.31, and xf86-ati is from git); my pc runs very weel except the video. In my xorg.conf i have radeon driver (also loaded in rc.con as a module) but when i enter in gnome all the windows and the desktop aren't smooth (i use chrome as a browser and when i scroll a page is not smooth at all). That means that this driver is not working correctly...... i use also the last mesa utils and glxgears works fine.....what can i do?

i cannot post now from linux, im in 7 so i can say only that the module is loaded correctly (in xorg i have accellmethod exa, like the archwiki says!!!), i have no problems at all to access gdm and gnome (and slo logout) but EVERYTHING is not smooth....what can i do to 'use' correctly the xf86 ati driver?? thanks in advance

Re: Dell Studio 1555: ati 4570

I managed to use 2d option by adding in grub kernel line nomodeset....but i can't use compiz because when i use fusion icon all the windows and the bars disappers, i can see only the mouse pointer and the desktop picture; i have to reboot. glxinfo say that direct rendering is yes , but when i run glxgears that' the error:

drmRadeonCmdBuffer: -22. Kernel failed to parse or rejected command stream. See dmesg for more info

this is dmesg (last error):
....
drm:radeon_cp_indirect] *ERROR* sending pending buffer 13

and few lines over:
...
[drm] Setting GART location based on new memory map
[drm] Loading RV710 PFP Microcode
[drm] Loading RV710 CP Microcode
[drm] Resetting GPU
[drm] writeback test succeeded in 2 usecs
...

So i disabled KMS, i'm now using radeonhd which has better powermanagement than radeon (63 degrees of radeonhd against standard 73 degrees of radeon), xorg-server 1.7, kernel 2.6.31...

Is there a solution?? THANKS

Hi
I can confirm this error with i686,
disabling drm in Decive section helps
so problem is with DRM drivers
of course drm is needed because of quality and performance

kernel 2.6.31-ARCH
xf86-video-ati 6.12.99.git20091014-1
ati-dri 7.6-2
mesa 7.6-2
xorg-server 1.7.1.901-1

thanks in advance for any help here

Re: Dell Studio 1555: ati 4570

bug is reported in freedesktop  bugzilla
https://bugs.freedesktop.org/show_bug.cgi?id=23664

I've reinstalled package ati-dri to old version 7.5.1 (dependency checking disabled) and there is no error anymore but  xorg reports missing library r600_dri.
there is no hardware acceleration because of that but software is working (better than nothing).

r600_dri is new module driver in 7.6. over there is our bug. we have to wait for newer version with fix.
unfortunately there is no option to use other drivers like radeonhd (it use ati-dri as well) or catalyst ( it's not working with new xorg).

How did you enable the power saving? And also, is there a chance to get even better results with the open drivers? fglrx could take down the temperature to 51°C

Re: Dell Studio 1555: ati 4570

that's my xorg,conf device section:

Section "Device"
    Identifier "Card0"                     # your alias
    Driver      "radeonhd"
    Option "AccelMethod" "uxa"            # to enable 2D and Xv acceleration on R6xx/R7xx - default AccelMethod shadowfb
    Option "DRI" "true"
    Option "Audio" "on"
      Option "HDMI" "all"
    Option "ForceLowPowerMode" "true"
        BusID       "PCI:1:0:0"
now my 4570 is at 60 c degrees..... in these days i tried everything to properly run 3d on this card, but no solution till now......

Re: Dell Studio 1555: ati 4570

I've created bug entry inside DRI section on https://bugs.freedesktop.org/show_bug.cgi?id=25008

As you can see there, they've propose install kernel from 2.6.32 tree (currently in arch we have 2.6.31).
where is the fix because of new kernel module

I've did that and i don't have problems with DRM. hardware acceleration starts to work.

someone was to fast by put newest mesa  to arch repository

try this as well, or wait to new kernel in arch
