I recently installed PCLOS to my desktop (second time). The first time the graphics seemed to work well. But this time the windows pop up rather sluggishly and full-screen videos are not smooth.
I have two graphics cards: the pre-installed, and an ATI Radeon 2600 card. But I can't choose between the two, only the ATI card is activated.
In the past, the default card has worked well, even better than the ATI (on another distro, for example).
Can /should I deactivate the ATI? If so, how do I do it?
Thanks to all for the time,
