in the other installation , minime if i remember correctly there wasn't any held packages but still i had the same problem, for some reason the ati driver seems to be incapable of load dri and do transparency on kde4 properly
the thing is that i can do glxgears and gives the same values i used to get in kde3 and kde4
the good thing is that jdownloader is working perfectly again in kde4

for some reason konsole takes more time to load compared to kde 4.3.4 and still can't get transparecy
the weird thing is that kde4 desktop effects work, terribly slow but works, of course, i disabled them immediately, no matter how i try to load compiz, manually or from 3d desktop menu in pcc, i remember i had a similar problem with pclinux 2007 and 2009.1 but i fixed it quickly with the exa/xaa setting but the driver change seems to be enough to make it impossible now
the weird thing is that in 2009.1 updated the same driver(it was using the radeon 9250 and earlier)with the same settings was perfectly stable and gave me compiz and transparency, also worked with kde4 desktop effects
"do you follow pclinuxos twitter/identi.ca channel?"
i remember the uploading the you know what to you know where message but i don't follow twitter and don't have the address
following this address
http://identi.ca/pclinuxosit reports that a wrong kernel is loaded, there is 6 available, perhaps i should load another
i am not sure if i need to reinstall system, i hope not because i don't have time, if that is the case i will have to abandon pclinux for some time untill i find the time to play with it, i will try to load another kernel
thanks for your help muungwana
