I just decided to now swap from Win to Ubuntu. Now after the install of the latest Ubuntu (13.04), the animations of the Desktop (just as open the dash-board) are very laggy and slow. I searched around the internet, but nothing of the answers fits my problem, since my Hardware is at least sufficient to render such animations. Here my specs:
- AMD Athlon II X4 640
- XFX R7770
- 8GB DDR3
The Hardware can't be the problem since it's running well under windows. I also updated Ubuntu to the current, and I'm using the xorg radeon driver. I also tried to edit the xorg.config, but it seems that won't work for me (I also read somewhere it's not used anymore ?!). And interesting fact is that Ubuntu doesn't detect my monitor (Medion) AND does only support 1024x768 and lower resolution. Maybe I'm to stupid to search for but I didn't come to a solution on my own.
My question is, does someone knows how I could fix this laggy GUI or at least know whats the source of my problem ?
