I have an Asus K52JB and my video card is ATI Radeon Mobility 5145. Just for some information i read here : http://ubuntuforums.org/showthread.php?t=1678044 that the card is based on the 4500 series.
So if i just don't install nothing, in "System Details">"Details" it tells me that my graphics are "Gallium 0.4 on AMD RV710".
I've tried to install fglrx drivers and AMD site drivers too but always gives me some problem.
On ubuntu 13.04 and 13.10 if i install these drivers, when i reboot the resolution is very bad and my unity and side bar doesnt show ( tried to reset unity, didn't work).
So i moved on to ubuntu 12.04, since it is a LTS and is older, maybe it could work. It didn't. When i reboot, my unity and side bar shows, but my resolution is very low and on options there's no option to an higher resolution.
With the default "Gallium 0.4 on AMD RV710" i tried glxgears. It gives me 60fps. I don't know if it is good or no.
Thanks in advance,
