I'm currently using Ubuntu 12.04 64bit. After installing ATI/AMD proprietary FGLRX graphics drivers via Additional Drivers, I checked the status of my VGA card using
lspci -v. Here's the output:
02:00.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI M96 [Mobility Radeon HD 4650] (prog-if 00 [VGA controller]) Subsystem: Dell Device 0456 Flags: bus master, fast devsel, latency 0, IRQ 46 Memory at d0000000 (32-bit, prefetchable) [size=256M] I/O ports at 2000 [size=256] Memory at cfef0000 (32-bit, non-prefetchable) [size=64K] [virtual] Expansion ROM at cfe00000 [disabled] [size=128K] Capabilities: Kernel driver in use: fglrx_pci Kernel modules: fglrx, radeon
As mentioned in the title, my VGA card is 1GB and yet my computer only recognizes 256MB. My question is: "How to make my computer fully recognize the capacity of my ATI Mobility Radeon HD 4650 (1GB)?"
