KDE4+ATI cards

[gezza]

Hi to all,
I managed to crash 2010 in a most spectacular fashion.
Somehow, I lost the video driver for the ATI card. The system rebooted to a text login and I ran PCC.
Although I selected the correct video driver and resolution, when I tried 'test' the system dissapeared into nomans land.
Rebooting brought me back to the text login.
Trying to apt-get the ATI driver, crashed, saying it could not load it..
48 hours later, I gave up and reinstalled 2009.2 to start again. This time the ATI driver was installed, I think, at least the screen looks good, but if I try to run the 'ati catalyst' it reports no ATI driver installed.??
I am still in 2009.2  preparing to upgrade to 2010, but why does the catalyst not run and why is there such a problem getting the ATI card recognised??
As always, your thoughts will be greatfully received.

pcc is one entity and kde4 is another, kde4 limits itself to do whatever pcc tells it to do

what video card do you have?

what driver did you installed?

RV280 ( Radeon 9200 PRO)
The module is Card-ATI-Radeon 9250 and earlier.
This is from the Control center.
Having lost the driver it became impossible to reinstall it.
I am currently in kde3 2009.2.
I must admit I thought the card had died. Re-installing showed that it was not.

my exact same video card using the same driver but i am using kde4 without a problem for years

a dead video card usually will not boot at all, no video

this sounds like you had problems with xorg.conf file, did you changed monitor or the resolution/refresh rate of the monitor?
