I'm running Leap_15.6 and having a problem with colors. The inxi info for the graphics is "Display: x11 server: X.Org v: 1.21.1.11 with: Xwayland v: 24.1.1". From a konsole when I view a file listing that has directories with permissions of 777 it's sometimes difficult to read them. When viewing this file "https://en.opensuse.org/File:Zypper-cheat-sheet-1.pdf" using either okular (23.08.5-bp156.1.2) or libreoffice (24.8.4.2-150500.20.15.1) portions are illegible. Specifically the ones with the neon green lettering on a white background. I've tried going into the settings on okular and changing the colors but it only affects the area surrounding the pdf. libreoffice will allow a change on a specific area of the display, only. I've looked into the system settings from System Settings->Appearance->Colors but it's the same, it only changes the colors for the area surrounding. I thought about adjusting the monitors color scheme, but I watch DVD's on it. Where else can I look?

There are reports that it is very difficult to select the color format with AMD's amdgpu driver. In particular, it is often the case that you cannot set it to RGB format, and YCrCb or limited RGB is automatically selected. For this reason, the color may look unnatural. Cf. 1. https://www.reddit.com/r/linux_gaming/comments/yo81p6/cautionary_tales_of_am... 2. https://www.wezm.net/v2/posts/2020/linux-amdgpu-pixel-format/ In particular, please read 2. It might be related to Carlos's advice. Moreover, there are reports that there are problems with color reproduction with AMD Cezanne due to recent driver updates. It is recommended that you add 'amdgpu.abmlevel=0' to the kernel command line to resolve this issue. Please have a look; https://community.frame.work/t/solved-color-issues-in-linux-6-9/52158/9 Best Regards. --- ┏━━┓彡 Masaru Nomiya mail-to: nomiya @ lake.dti.ne.jp ┃＼／彡 ┗━━┛ "During testing, Sakana found that its system began unexpectedly attempting to modify its own experiment code to extend the time it had to work on a problem." -- Research AI model unexpectedly attempts to modify its own code to extend runtime (ars TECHNICA) --

I'll be moving it, back, to a HP 27" monitor, don't know the model number, in about 3.5 weeks, and I expect the color issue will change completely.
Best Regards. And to you also.

There are reports that it is very difficult to select the color format with AMD's amdgpu driver. In particular, it is often the case that you cannot set it to RGB format, and YCrCb or limited RGB is automatically selected. For this reason, the color may look unnatural. Cf. 1. https://www.reddit.com/r/linux_gaming/comments/yo81p6/cautionary_tales_of_am... 2. https://www.wezm.net/v2/posts/2020/linux-amdgpu-pixel-format/ In particular, please read 2. It might be related to Carlos's advice. Moreover, there are reports that there are problems with color reproduction with AMD Cezanne due to recent driver updates. It is recommended that you add 'amdgpu.abmlevel=0' to the kernel command line to resolve this issue.
