[SOLVED] Rendering display in Grayscale
Hi,
I'm using Arch with XFCE on a laptop (Intel Graphics). Is there a way to render the display grayscale (black and white)?

Re: [SOLVED] Rendering display in Grayscale
"man xorg.conf" tells me there is a display setting which might achieve what you want (never tried it).
Visual "GrayScale"

Re: [SOLVED] Rendering display in Grayscale
You'll also have to set the depth to 8bit what's likely gonna break quite some applications (which will boldly assume there're 4 bytes/pixel)
@vraskolnikov, what's the actual purpose here? Do you have have an nvidia GPU? (The blob supports "digital vibrance" per output, which basically controls the saturation per monitor) and can be abused to get a grayscale output on a TrueColor server. I'm not sure whether there're general tools (like xcalib) that can do this.

Re: [SOLVED] Rendering display in Grayscale
Thanks for the suggestions. I don't think my video card supports the GrayScale mode.
@seth I only use my laptop for reading so I didn't need color. Android has a monochrome mode which is handy. Given redshift and similar programs, wanted to know if monochrome was possible.
I'd looked at some color calibration tools but so far unhelpful.
Closing this topic, marking as solved.

Re: [SOLVED] Rendering display in Grayscale
The only thing that will work regardless of the GPU/driver is the compositor; compiz had this feature - but this means you'll have to replace xfwm4 w/ compiz.
