Hello all, Recently I bought a small HDMI connected 1024x600 pixels TFT display. It seems that 11-stable does not find the correct dimensions automatically. The kernel apparently assumes the display to be far larger than it actually is and a lot of text simply disappears below the lower edge of the screen. So, I assumed there might be some method to tell the kernel the default dimensions to use when it fails to confirm the actual values from the display device itself. Now I would like to check whether I am interpreting things correctly. Apparently there is kernel MIB variable for this purpose on 12.x series (kern.vt.fb.default_mode) but not on 11.x. If this is true, I would like to understand why is the feature not available on 11-stable as well? Have I understood the meaning of the default_mode variable correctly for 12.x and will it work properly for a 1024x600 display? Moving over to 12-stable will not be a big issue on a new system, if that is necessary, but I would like to avoid taking the effort of upgrade unless I can be relatively sure it will solve my problem. --jau
