Title:
[RV635] No hardware acceleration on ATI Radeon 3650 HD using 'radeon'
driver
Status in X.org XServer - ATI gfx chipset driver:
Won't Fix
Status in “xserver-xorg-video-ati” package in Ubuntu:
Invalid
Bug description:
Binary package hint: xserver-xorg-video-radeon
On Lucid Lynx, after few updates I completely lost graphics hardware
acceleration. As fglrx won't work with new xorg, I use radeon driver
(my card is ATI Radeon 3650 HD). I used to have perfect 3d graphic,
compiz and games used to work smoothly, but from some time I can't use
any of them, when I lunch a game it consumes 100% cpu and lags a lot,
and when I start compiz, it says
compiz (core) - Fatal: Software rendering detected.
compiz (core) - Error: Failed to manage screen: 0
compiz (core) - Fatal: No manageable screens found on display :0.0
so my guess is that the radeon driver is not providing me with 3d hardware
acceleration.
=================================
I don't know if it is a significant tip, but I found out that use-count of
module 'radeon' is 0, as lsmod shows.
Module Size Used by
radeon 738407 0
ttm 60847 1 radeon
drm_kms_helper 30742 1 radeon
drm 198930 3 radeon,ttm,drm_kms_helper
i2c_algo_bit 6024 1 radeon
...
================================
I have no idea on what can be wrong. Maybe the problem is somewhere in
my configuration (but I doubt it), maybe it's a bug in radeon driver,
or maybe it's a bug somewhere else.
I hope debug info I provide will be useful.
(EE) RADEON(0): [dri] RADEONDRIGetVersion failed because of a version
mismatch.
