Thank you! Its easier when I get the questions for specific problems in
the documentation :-)

That was fixed in 3.2-rc1, where also we have:
[acme@felicio linux]$ cat tools/perf/Documentation/perfconfig.example
[colors]
# These were the old defaults
top = red, lightgray
medium = green, lightgray
normal = black, lightgray
selected = lightgray, magenta
code = blue, lightgray
[tui]
# Defaults if linked with libslang
report = on
annotate = on
top = on
[buildid]
# Default, disable using /dev/null
dir = /root/.debug
[acme@felicio linux]$
So you can use:
[tui]
report = off
To disable the TUI altogether or use:
$ perf report --stdio
Or tweak the colors to your liking.
By default the TUI now uses whatever color is configured for your xterm,
not something fixed as in the past, which was a common source of
complaints, that, unfortunately I only heard indirectly :-\
Ah, if you still need to configure the colors, use "default" so that it
will use whatever is the color configured in your
xterm/gnome-terminal/whatever profile.
For reference, the default set of colors now is (from
tools/perf/util/ui/browser.c):
static struct ui_browser__colorset {
const char *name, *fg, *bg;
int colorset;
} ui_browser__colorsets[] = {
{
.colorset = HE_COLORSET_TOP,
.name = "top",
.fg = "red",
.bg = "default",
},
{
.colorset = HE_COLORSET_MEDIUM,
.name = "medium",
.fg = "green",
.bg = "default",
},
{
.colorset = HE_COLORSET_NORMAL,
.name = "normal",
.fg = "default",
.bg = "default",
},
{
.colorset = HE_COLORSET_SELECTED,
.name = "selected",
.fg = "black",
.bg = "lightgray",
},
{
.colorset = HE_COLORSET_CODE,
.name = "code",
.fg = "blue",
.bg = "default",
},
It should all be fixed up now, together with many other improvements
that should make the TUI and stdio default user experience similar up
till you start using the navigation keys to do things that only are
possible with a TUI, like folding/unfolding callchains, etc.
Please let me know about any other problem you may find with it!
