-------------------------------------------------------------------------
Q1. The sysinfo output of linux_logo looks garbled. What can I do?
A1. First check your version of linux_logo (with "linux_logo -v") and
see if it is the newest version available at the web-page. If not,
try getting the newest version.
If it still doesn't quite look right, e-mail me a copy of your
/proc/cpuinfo file and I'll do my best to fix things up.
Q2. Linux_logo reports I have 1 megabyte less RAM than I actually do.
A2. If you have ACPI power management enabled, it uses some of your RAM.
Also, if you have a built-in video card it will use some of the system
RAM for video, which keeps Linux from seeing it.
The "/proc/kcore" method of RAM detection I use doesn't count this
RAM, thus misreporting it.
I have added a hack for intel architectures that checks /proc/iomem
for ACPI support and "fixes" the output. Unfortunately this only
works on 2.3.x kernels and later.
Q3. I don't like the periods in the classic logo.
(or) What happened to the old "-n" option
A3. I was going to add back code that would take care of this. But
I am trying to avoid special-case code like this. I spent most of
the 3.9 development series getting rid of such hacks.
So the solution is simply to edit the "logo_config" file and change
the line that says
./logos/classic.logo
to say instead
./logos/classic-no_periods.logo
and recompile.
Q4. How can I make linux_logo run every 15 minutes or so, that way I can
use the uptime option and impress my windows-using friends with my
incredible uptime?
A4. This is a common question. The best thing to do is use cron.
[See "man crontab"]. Setting up cron can be a bit tricky, but
a line such as
*/15 * * * * linux_logo -u > /etc/issue.net
Should have issue.net updated every 15 minutes. Setting up a crontab
file is a bit beyond the scope of this document; please see the
manpage for details.
Q5. Can I have linux_logo stay on top of the screen while things scroll
in a window beneath it?
A5. Bill Anderson <bill _at_ tb.dynip.com> did some research and came up with this:
I did successfully use:
clear; /bin/echo -e '\033[018;25r' ; linux_logo
to put the linux logo and info on the top 18 lines (fewer if you don't
care about the system info) of the screen and let the rest scroll...
/bin/echo -e '\033[0;0r'
will turn it off again...
Q6. How can I keep the system info from being centered?
A6. Starting with version 4.03 you can just use the "-k" command line option.
On old versions you can use sed to do this. (This only works with the
-a ascii output option because otherwise centering is done with ANSI
escape sequences).
linux_logo -a -g | sed 's/^ *//'
Q7. Did you invent the Linux "Tux" logo?
A7. No. Sometimes there seems to be some confusion about this. I am only
responsible for the program "linux_logo."
Tux the Linux penguin was invented by Larry Ewing. See his page here
for more info: http://www.isc.tamu.edu/~lewing/linux/
Q8. Why don't you use the GPL3 license?
A8. I have been using the GPL2 for 10 years, and trust it, and feel no
need to change that now. It's my software, I get to pick the
license.
Q9. Why don't you use "real" automake config files?
A9. I *hate* automake based config files. Sure, when they work it's
all happiness and fun, but when something goes wrong good luck
figuring out what if you don't have a PhD in the m4 language.
I also refuse to ship a "configure" file that's larger than all
of the rest of my project put together.
So for now you'll have to use my hacked up fake configure
program.
