I have problems with my ati hd 5450 graphic card driver installation. The problem is that my picture lags when i resize window or try to move window through my desktop etc... with ati proprietary drivers.
One more example. I have installed google-chrome and firefox. When I watch movie clips with chrome on youtube it is ok with open-source drivers (radeon) or with ati proprietary drivers. When I lunch firefox and open some movie picture starts to lag.
I tryed to install ati drivers from official debian repository and from ati official web page.
I followed couple tutorials just to be sure that everything is ok.
1. Downloaded gcc, make, linux-headers
2. unpack ati drivers
3. run sh amd-* command
after installation was finished I reboot my computer and check if flgrx module is running. That was ok, but picture still lags.
Can anyone guide me how to properly install drivers for my card or tell me why picture lags?
