Description of problem:
On the Linux console we can use fonts with more than 256 glyphs
("512-glyph mode"). But such "big" fonts cause some restrictions. Due
to VGA hardware limitation, it is impossible to use "intensity" bit
when 512-glyph font is used. In other words, instead of two groups of
colors (0-7 and 8-15), we have only one (0-7).
As a result, console colors are spoiled. First of all, yellow color
completely disappears! Besides there is no possibility to choose two
kinds of intensity.
Currently, I couls not find a mention of this feature anywhere in
the distribution. Therefore it would be quite good to add some
words, for example, to setfont.8
Version-Release number of selected component (if applicable):
Steps to Reproduce:
To see the color difference under 256/512-glyph fonts:
1. Load some 512-glyph font, for example:
2. Run "ntsysv", "mc" or some another console (curses/slang) applications.
Actual Results: In "ntsysv", service names are reddish (or
red-brown) instead of pure yellow.
In "mc", the same is for panel headers. Additionally, subdirectory
are not highlighted (but should be).
Expected Results: Expected results may be seen just after loading
of any 256-glyph fonts:
Now "ntsysv" and "mc" has yellow, subdirectory in "mc" are highlighted.
More evident test is possible:
Run "mc" on one virtual console, then switch to another and load
256/512 fonts on it. After loading, switch back, type Ctrl-L (to
redraw MC, because consoles are damaged immediately after "setfont")
and see the difference.
This issue is actual for RedHat, because since RedHat-9, the
512-glyph font "latarcyrheb-sun16" is used for initial installed systems.
I have spent some hours to understand who has eaten yellow color on
my just bought computer. Some UNIX users whom I wanted to transfer on
RedHat, have told that "Midnight Commander at your Linux looks
The advanced users can faster cope with this issue if there will be a
mention of it in the documentation.
I have made a small patch for setfont.8
Created attachment 107487 [details]
Patch for setfont.8 manual
Add some words to the setfont.8 manual about side effects on 512-glyph font
Thanks for the patch!
As you might have already noticed, I have forwarded it upstream;
in rawhide it should appear in kbd-1.12-4.
