A sys wide graphics changer like gimp?

Edward1978

How hard would it be for someone to make a Gimp like program to change the whole screen like it does pics? We prob. don't need all the options GIMP has. more like a calibrater that you can just go by eye. The OSD of my monitor is bad, I can't even see it (Vision issues).

Hello Edward, can you provide more details as what you are working to accomplish in setting screen size and screen font size to help with your VISION needs?
Detailed answers from you, Edward's, previous post
I read your previous answers in your post, to my present following questions. OSD stands for ?? On Screen Dxxxx ?? What is you monitor hardware make, model, or URL to the specifications; and screen pixel size support? 1920x1080 or other pixel size dimension like 1024 x 768 or 1280 x 1024 ? Does this support multiple screen dimension sizes?

I look forward to helping you have satisfactory VISION experience with your nice Monitor and computer running GhostBSD.
I am curious to know if you use ORCA screen reader with GhostBSD operating system to help with your limited vision, Edward? Software Station can help install ORCA for you, from the binary packages.

CLI commands are useful: xconfig and xrandr:
xconfig: GROK xconfig useage example
Use xrandr (Quick/Temporary Change from Terminal)Open a terminal (Menu → System Tools → MATE Terminal) and run:

bash:
xrandr

MATE has limited fractional scaling, but adjust DPI:

Menu → System → Preferences → Appearance → Fonts tab → Details button → set DPI (e.g., 144 instead of ₉₆ for HiDPI screens).

Posting now, before I make a too complicated answer, Edward. Fred Will research setting monitor details from the Operation System.

xrandr settings for gamma, brightness, contrast This GROK answer is helpful, Edward.

@Vimanuelt has a github for setting display brightness controls, listed by Grok.
GhostBSD-Specific or Recommended ToolsFrom GhostBSD community discussions (forums.ghostbsd.org):

brightness-control tool (GUI for brightness + contrast):
A community member created this specifically for GhostBSD/MATE users with lacking contrast/brightness.
Install and run it:

bash
sudo pkg install git
git clone vimanuelt/brightness-control
cd brightness-control

Follow README for build/make/install (usually simple make + sudo make install)

I share this as helpful knowledge, with you Edward.

Edward1978

wb7odyfred Is this on the software station too?

Edward1978

wb7odyfred When I click the link, is is dead. Ao will this work? bash
sudo pkg install git
git clone vimanuelt/brightness-control
cd brightness-control

Here are two options. The first one is what Fred had mentioned. I moved it to a new location.
(1) xcrsz/brightness-control
(2) xcrsz/display-control

The first one is open source. The second one is just an experiment. I develop and maintain my software on an internal server. I periodically mirror selected repositories to a public Git server to showcase my work. GitHub is used for visibility, not as my primary development platform.

vimanuelt Is there a command to check for & download deps if they are not on the sys? Free/GhostBSD would benefit of the package man. checked for then & downloaded them if needed.

vimanuelt

Edward1978
No, there isn't as these apps are just workarounds. But there is a README.md file that describes the requirement.

What are the commands for xranr to change contrast/gamma/saturation?

vimanuelt

Edward1978
Assuming you are using HDMI-1:
Gamman and Contrast: xrandr --output HDMI-1 --gamma 0.9:0.9:0.9
Saturation: xrandr --prop

Edward1978

Ok, I can't adjust a pic in GIMP to make it much better, a way to put the values in a .icc to beable to use it (Mate can use a .ICC right?) or a calibration prog. that you can do just by eye. Nature is a bit cruel to those who do nothing, when I first got this monitor maybe a week back, tears ran down my face how good it looked, but I have Vision issues. Not sure what happened, after I watched the vid. The next day on. It was like a cruel hand slapped me & took that clarity away/ I Just want to watch vids & play games. I download arandr, the GUI frontend. I can't find it. It isn't in the menu.

You can open a terminal and run it from the command line.

As an aside, many new external monitors allow you to change settings.

https://x.com/i/grok/share/9a082d084b8847bf96d1634947863f64 Edward, I appreciate your tenacity and patience. I use Grok to provide hints and examples in answer to your question about xrandr changing ?? gamma and saturation. Yet GROK suggests using the buttons on the monitor hardware to change those settings, That xrandr is not able to change those settings directly.

Quick Tips

Reset to defaults: xrandr --output HDMI-1 --brightness 1 --gamma 1:1:1 or reboot.
If changes revert: Some drivers reset on suspend/resume—add commands to a script in ~/.config/autostart/ or Startup Applications.
Color calibration (advanced): Install argyllcms via sudo pkg install argyllcms and use dispcal for proper ICC profiles, but that's overkill for basic tweaks.

Start with xrandr examples above—they're instant and reversible. If you share your xrandr output or describe your hardware (laptop/desktop, GPU, monitor type), I can give exact commands! Check GhostBSD forums for more hardware-specific threads.
