Thanks SW, I appreciate the assistance. I'm a bit confused about this whole thing though. I reinstalled Pardus 2009.2 and the lsmod output is similar to Pardus 2011.1:
Pardus 2009.2:
airtight@airtight-pardus ~ $ lsmod | grep radeon
radeon 435140 2
ttm 36332 1 radeon
drm_kms_helper 25252 1 radeon
drm 148036 5 radeon,ttm,drm_kms_helper
i2c_algo_bit 5104 1 radeon
Pardus 2011.1:
airtight@pardus2011-airtight-laptop ~ $ lsmod | grep radeon
radeon 555117 2
ttm 46322 1 radeon
drm_kms_helper 25030 1 radeon
drm 150107 4 radeon,ttm,drm_kms_helper
i2c_algo_bit 3890 1 radeon
In the output above for Pardus 2009.2, it doesn't say VMware or Gallium. In the list of drivers in the Video Card Configuration I can see only radeon, radeonhd, ati and vmware. So the output above seems to be saying that a driver called radeon driver is being used, not the official fglrx driver. Am I interpreting that correctly? Also, I searched in Package Manager for fglrx and found these uninstalled entries (see attached picture) so maybe the official fglrx driver wasn't being used by default, maybe it is up to me to install it and then select it from the list of drivers. But then why does it already mention ati and vmware in the dropdown list of drivers?


Just want to be clear on this. My (and yours) graphics chip is:
lspci -nn | grep VGA
01:00.0 VGA compatible controller [0300]: ATI Technologies Inc RV350 [Mobility Radeon 9600 M10] [1002:4e50]
So it seems that whatever applies to chip R300 also applies to the RV350, is that right?
Seems that Kwin not using the capabilities of the grafic engine since KDE 4.6.x

Yes, a regression. Just goes to show that new is not always better.
Maybe KDE 4.7.x brings some improvement. This is not only related to Pardus 2011....also other Distribution using KDE 4.6.x until 4.7.x should have this problem!

We're all in it together!

On a side note, in the output of lshw into html, the "display" section that shows my chip details, is in red, as are a three or four other entries. Anyone know what this means?
