im tottaly new in ubuntu.i have hp pavillion dv6 3035et and it has two graphics cards in it (one of them is ati hd5650 and other is onboard intel) and i couldnt install a driver even one of them.first,i had ubuntu 11.04,it was nice when first installed,compiz and unity worked.but it also sometimes freezed with a black screen when booting.then i installed ati fglrx in the additional drivers section.and it has caused dissappearance of compiz and unity.it was ok,before i installed ubuntu 11.10,unity appeared again (no compiz again) ,i tried to install fglrx in additional drivers but i saw there are two additional drivers (there were one in ubuntu 11.04 ) and when i tried to install second one,it gave an error.so in the end,i got a slow unity,no compiz,when i looked in system information,it says no graphics cards in it.so what do i have to do? i tried to installing ati drivers manually in amd website too.none of them worked.(when i try to open catalyst control center,it also gives an error)

You might have to use the radeon open source driver. fglrx is currently buggy.
When u check your system info, it says no graphic card or graphic card unknown? If it is graphic card unknown, open up a terminal and type $ sudo apt-get install mesa-utils. I believe it will show that you are using intel sandy bridge mobile, if you have no ati driver install. To properly install ati driver, follow this
