Question from a graphics ignoramus - how do you get all this information about the graphics controller? "sudo lspci -vvv" tells me that my Sony C1VFK Picturebook has ============================================== 00:0d.0 VGA compatible controller: ATI Technologies Inc Rage Mobility P/M (rev 64) (prog-if 00 [VGA]) Subsystem: Sony Corporation: Unknown device 80af Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping+ SERR- FastB2B- Status: Cap+ 66Mhz- UDF- FastB2B+ ParErr- DEVSEL=medium >TAbort- <TAbort- <MAbort- >SERR- <PERR- Latency: 66 (2000ns min), Cache Line Size 08 Interrupt: pin A routed to IRQ 9 Region 0: Memory at fd000000 (32-bit, non-prefetchable) [size=16M] Region 1: I/O ports at 1400 [size=256] Region 2: Memory at fc105000 (32-bit, non-prefetchable) [size=4K] [virtual] Expansion ROM at 0b000000 [disabled] [size=128K] Capabilities: [5c] Power Management version 1 Flags: PMEClk- DSI- D1+ D2+ AuxCurrent=0mA PME(D0-,D1-,D2-,D3hot-,D3cold-) Status: D0 PME-Enable- DSel=0 DScale=0 PME- ============================================== and that is about all I know.
