My code for Graphics Memory & Screen Size for Virtual Desktop

Hey folks,

Heres some useful code you can insert in your scripts for Graphics Memory & Virtual Desktop settings.

# Set up a virtual desktop routine (not tested on any other computer!)
read RES_X RES_Y <<<$(xdpyinfo | awk -F'[ x]+' '/dimensions:/{print $3, $4}')

# Set Virtual Desktop to computers screen resolution
Set_Desktop "On" "$RES_X" "$RES_Y"
POL_Wine_X11Drv "GrabFullscreen" "Y"

# Graphic Card Memory Routine (not tested on any other computer!)

VARVMS=$(lspci -v -s `lspci | awk '/VGA/{print $1}'` | sed -n '/Memory.*, prefetchable/s/.*\[size=\([^]]\+\)\]/\1/p')

VARVMS=${VARVMS//[!0-9]/}

POL_Wine_Direct3D "VideoMemorySize" "$VARVMS"

They are code snippets to be added into a script.

The VARVMS=$(lspci -v -s `lspci | awk '/VGA/{print $1}'` | sed -n '/Memory.*, prefetchable/s/.*\[size=\([^]]\+\)\]/\1/p')
can also be typed into a bash terminal as is, then type into the terminal:

echo $VARVMS

This will print the result to the terminal in Linux (not sure about MAC)

See this page which will explain how I obtained the info. for video card memory:

This is'nt a memory fix. It's just a way of obtaining information on your video card memory. When I was given this computer I had no information about it's specifications and all the hardware utilities I have used in linux fail to supply this information for some reason. After hours of searching I found this site on the web (see above) which gave me the information on how to get the information. This gave me the info I required for putting some code which I discovered on yet another site and bringing it all together in the code snippet above. I had to add a final line of code to remove the 'M' from the number so that the variable I named VARVMS could properly be set in the windows registry. Phew!

Okay this is a long-winded way of obtaining the information about your video graphics card memory in Linux (not sure about unix in Mac)

1. The command 'lspci' should work for obtaining the hardware of your computer type this into your consul/terminal.


2. The command 'lspci' is a utility for displaying information about all PCI buses in the system and all devices connected to them.

3. Below is an example output from the terminal/consul:

what we are looking for is marked in bold VGA if you see what I mean.

4. This is the crucial part make a note of the number here for example I have '00:02.0'

5. If you cannot find devices in the specified domain use following command and look for your display card name and memory field:

lspci -v | less


7. Now we need to use string called devices in the specified domain – 00:02.0 VGA ):

lspci -v -s 00:02.0

Sorry called away now look at the line 'Memory at c0000000 (32-bit, prefetchable) [size=256M' this gives your graphics memory.

e.g. 256M

So we use VARVMS=$(lspci -v -s `lspci | awk '/VGA/{print $1}'` | sed -n '/Memory.*, prefetchable/s/.*\[size=\([^]]\+\)\]/\1/p')

to essentialy look for the word 'prefetchable' and take as our variable what follows after that word to the end of line which we assign as the variable VARVMS.

8. We now need from the variable I assigned as VARVMS to trim it to a number using the next line of code:


VARVMS=${VARVMS//[!0-9]/}
which strips out any non-numeric from this variable to remove the 'M' which was the last alpha-numeric letter at the end of the line in the log file which stores PCI information.

9. Now we have only the number we can assign it to the windows registry editor for video memory:

POL_Wine_Direct3D "VideoMemorySize" "$VARVMS"

I not going to explain all the code '#"%^&laugh)**^&out*^"^^(loud!

But it should provide those who don't know how much Video RAM they have with an answer.

Test out the code like so and press return at the end of each line in a terminal/console:


VARVMS=$(lspci -v -s `lspci | awk '/VGA/{print $1}'` | sed -n '/Memory.*, prefetchable/s/.*\[size=\([^]]\+\)\]/\1/p')

VARVMS=${VARVMS//[!0-9]/}

echo $VARVMS

This should display a number which is your Video Grahic Memory.

BTW this was written in the local ale house and there may be 'Hic!..ups' here.

There is one problem with this method. Most nvidia gpu's (as well as AMD gpu's according to my googling) do not display correct memory size in lspci. I can use my card as an example here. My gpu is an nvidia GTX 980M. Total memory according to nvidia-settings is 4096 MB, or just 4 GB. This is also correct to the vendor where I purchased my card.

However, lspci displays the following:

Code:

01:00.0 VGA compatible controller: NVIDIA Corporation GM204M [GeForce GTX 980M] (rev a1) (prog-if 00 [VGA controller])
   Subsystem: ASUSTeK Computer Inc. Device 22da
   Flags: bus master, fast devsel, latency 0, IRQ 26
   Memory at ec000000 (32-bit, non-prefetchable) [size=16M]
   Memory at c0000000 (64-bit, prefetchable) [size=256M]
   Memory at d0000000 (64-bit, prefetchable) [size=32M]
   I/O ports at e000 [size=128]
   [virtual] Expansion ROM at ed000000 [disabled] [size=512K]
   Capabilities: <access denied>
   Kernel driver in use: nvidia
   Kernel modules: nouveau, nvidia_drm, nvidia

So I am afraid that parsing lspci output will not yield correct results for nvidia and amd gpu's.

I see what you mean. I just did a search and read the last comment at the bottom of this page:

http://www.binarytides.com/linux-get-gpu-information/

I suggest reading this it does explain the complexities involved to get information on your Graphic card memory
