[linrad] Reboots with helper-module; Re: [linrad] Re: Installation adventures (Debian Sarge)/contest

Merci bien Monsieur Patrick!

Well, I guess everything was right after the 'make install' of
svgalib 1.9.20 as I made the svgalib_helper.o separately in its
own directory. But I did NOT boot my PC before starting 'Linrad'!

So 'Linrad' did not get to see the helper-module, and I went back
to a new svgalib-install with the NO_HELPER option. Surely this
allows me to operate linrad in 'root' mode, but of course I would
like to see the other option to succeed at least once...

Actually I did later multiple reboots with the X-server experiments,
but as stated it did not provide the wanted action. My local guru
mentioned that getting xfree86 to work in various Debian's can be
quite a challenge... so we are still at that level.

If my HomePNA would work automatically I would now do a Sarge k3.6.8
install after the 2.4.27 version. But actually there is nothing to
complain about as 'Linrad' is already up and running; just the mouse
is missing.... It seems that CPU load is about 5% and delay 0.5 s
(screen values only; probably second sound card needed ...)

I used the old version of svgalib in my test, so I have no idea on how
svgalib 1.9.20 may behave.

That could cure the problem, but this would be my last option to load
the helper module.

No convention hasn't changed, but I may have done a mistake in my
install procedure. On my system, the svgalib folder is in /usr/src,and
it worked like that. So this is not the cause of your problem. Anyway, I
recommend everyone to use Leif's convention (/usr/local/src) and I shall
post shortly a new version of my installation procedure.

I do agree with this too, but first let me explain how the "helper"
setup works.
After linrad had been compiled you have an extra command : 'make
svgalib' this command add several symbolic link in the /etc/rc0.d to
rc6.d. This add a new function during the boot process and the function
in to do an 'insmod' of the helper_module.

So if you do not want to 'reboot' your system, you can do the insmod by
hand, but you would have to do this every time you boot your PC. :-(
Rebooting the PC let you check that everything is correct in the boot
process ( It is not the case for you !)

Ok, now let's try to figure out what happened on your system :

first of all, open a terminal with root privileges and type :


This will give you the list of the loaded modules, you should find a
line starting with svgalib_helper. I suppose that you haven't or it
would work...

Check in /etc/rc5.d (/etc/rc3.d if you are in text mode) that you have a
symbolic link named S96svga pointing to /etc/init.d/svga. Check if this
file exists.

Read the file with the following command :
less /etc/init.d/svga

You should see after the start flag a line containing something similar
to this :
insmod /usr/src/svgalib/svgalib-1.9.19/kernel/svgalib_helper/svgalib_helper.ko

in your case, you may find svgalib-1.9.20 or even /usr/local/src.
Whatever you find there, check if this file exists. If it doesn't try to
locate the svgalib_helper with the command :

updatedb   (Do this only once, it may take a while !)
locate svgalib_helper.ko

and edit /etc/init.d/svga to fit the path.

you can test the new svga file by typing :

/etc/init.d/svga start

and see if any error message. If none check if the svgalib_helper is
loaded with the 'lsmod' command.

Last (sorry to say that !) reboot your PC, the lsmod should show the
svgalib_helper loaded during boot process.

I hope all this will help.
