Checking Memory Size of VGA (onboard)

Checking Memory Size of VGA (onboard)

To know the memory size of your VGA which is onboard, type:

root@galaxy:~# lspci

00:00.0 RAM memory: nVidia Corporation Unknown device 0547 (rev a2)

00:01.0 ISA bridge: nVidia Corporation Unknown device 0548 (rev a2)

00:01.1 SMBus: nVidia Corporation Unknown device 0542 (rev a2)

00:01.2 RAM memory: nVidia Corporation Unknown device 0541 (rev a2)

00:02.0 USB Controller: nVidia Corporation Unknown device 055e (rev a2)

00:02.1 USB Controller: nVidia Corporation Unknown device 055f (rev a2)

00:04.0 USB Controller: nVidia Corporation Unknown device 055e (rev a2)

00:04.1 USB Controller: nVidia Corporation Unknown device 055f (rev a2)

00:06.0 IDE interface: nVidia Corporation Unknown device 0560 (rev a1)

00:07.0 Audio device: nVidia Corporation MCP67 High Definition Audio (rev a1)

00:08.0 PCI bridge: nVidia Corporation Unknown device 0561 (rev a2)

00:09.0 IDE interface: nVidia Corporation Unknown device 0550 (rev a2)

00:0a.0 Ethernet controller: nVidia Corporation Unknown device 054c (rev a2)

00:0b.0 PCI bridge: nVidia Corporation Unknown device 0562 (rev a2)

00:0c.0 PCI bridge: nVidia Corporation Unknown device 0563 (rev a2)

00:0d.0 PCI bridge: nVidia Corporation Unknown device 0563 (rev a2)

00:0e.0 PCI bridge: nVidia Corporation Unknown device 0563 (rev a2)

00:0f.0 PCI bridge: nVidia Corporation Unknown device 0563 (rev a2)

00:10.0 PCI bridge: nVidia Corporation Unknown device 0563 (rev a2)

00:11.0 PCI bridge: nVidia Corporation Unknown device 0563 (rev a2)

00:12.0 VGA compatible controller: nVidia Corporation Unknown device 053e (rev a2)

00:18.0 Host bridge: Advanced Micro Devices [AMD] K8 [Athlon64/Opteron] HyperTransport Technology Configuration

00:18.1 Host bridge: Advanced Micro Devices [AMD] K8 [Athlon64/Opteron] Address Map

00:18.2 Host bridge: Advanced Micro Devices [AMD] K8 [Athlon64/Opteron] DRAM Controller

00:18.3 Host bridge: Advanced Micro Devices [AMD] K8 [Athlon64/Opteron] Miscellaneous Control

From the output results, look out for the VGA information, paying attention particularly to the strings of number on the left of the word VGA. In my case it is 00:12.0

With this information, type:

root@galaxy:~# lspci -v -s 00:12.0

00:12.0 VGA compatible controller: nVidia Corporation Unknown device 053e (rev a2) (prog-if 00 [VGA])

Subsystem: Biostar Microtech Int’l Corp Unknown device 1406

Flags: bus master, 66MHz, fast devsel, latency 0, IRQ 5

Memory at fb000000 (32-bit, non-prefetchable) [size=16M]

Memory at e0000000 (64-bit, prefetchable) [size=256M]

Memory at fc000000 (64-bit, non-prefetchable) [size=16M]

[virtual] Expansion ROM at 88000000 [disabled] [size=128K]

Capabilities: [48] Power Management version 2

Capabilities: [50] Message Signalled Interrupts: Mask- 64bit+ Queue=0/0 Enable-

So the onboard VGA memory is 16MB. This information is necessary if you want to set the X configuration file.
