I have a HP G62 notebook. Video card is:
$ lspci | grep VGA 01:05.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI RS880M [Mobility Radeon HD 4225/4250]
I have a bigger monitor connected to this computer with a D-Sub VGA cable. Today I just upgraded from 12.04 to 13.04. The result was that dual monitor is not working anymore. Catalyst is not working either. I have tried to install binary dirvers from AMD.
But the installer tells me that my video card is not supported. All I need is Full HD output on the D-Sub port of the notebook.
fglrx module cannot be loaded. It tells me there are no compatible adapters. Ubuntu supplied
fglrx-updates packages do not work either. The best resolution I can get is
1368x768 on the laptop's display. But I bought the bigger monitor for a reason, and I really need it. Please help.
