On my Dell laptop, the F11 & F12 keys do work for brightness.

Thank you for responding.

Both the commands you suggested appear to have been executed normally.
Actually, the lines are too many, and I cannot see all the lines.

But I see the message:
tail: cannon open '+2' for reading: No such file or directory
at shutdown.

I placed a script in /etc/profile.d, which goes like this:
Code:
#!/bin/sh
cd /sys/devices/platform/i8042/serio4/serio5
echo -n 120 > speed
echo -n 240 > sensitivity

cd /root
echo 2 > /sys/class/backlight/acpi_video0/brightness


This script is for setting the sensitivity of the mouse and the brightness of the display. The script disappears on reboot, and takes no effect.

When TazPup is installed to a hard drive (frugal install with a save file), the script does not disappear, and those values are set as expected.

I"m not sure if the following sheds any light in your error or not:

Hi mistfire, tazpkg is working well, including install dependencies on alpha 11

So I'm looking at alpha 11, now. the Shebang still says ash for snapmergepuppy. Maybe changing it to bash would help like it did on alpha 9. The other thing that the above script did was installed the coreutils version of readlink. I don't know if this is necessary or not on alpha 11. Will test.


Yes, or/and as i suggested here (busybox tail +2 and shebang change to bash)

Edit: after googling "busybox tail +2" the following rings a bell:

Code:

So try -n +2 or --lines=+2

Is “tail +2” supported by Linux?

If tail is now linked to "coreutils" instead of busybox, it could explain the error. I think that "tail +2" isn't as universal, and that "tail -n +2" should be used for greater compatibility.

Try this:
Code:

grep -rn '/etc' -e 'tail +2'

https://stackoverflow.com/posts/16957078/revisions

and when we find where it occurs then we can apply the above fixes.

Since you are using a save file, you'll have to mount it as a loop device to edit the files. I'm not sure if you'll be able to do this if it is the same save file that you use to boot so maybe boot with a different save file and or directory or even in ram mode before editing.

I opened snapmergepuppy and replaced "tail +2" with "tail -n +2".

This seems to have fixed the problem.

I no longer see the message at shutdown:
tail: cannon open '+2' for reading: No such file or directory

After reboot, there remain the changes I made in the previous session. Thank you.

tail +N is an old syntax, but busybox tail still supports it; and I thought Slitaz included busybox and snapmergepuppy calls 'busybox tail +2', which should work, unless someone has removed the reference to busybox, which is the mistake really.

But if not using busybox tail, then, yes, tail -n +N would work with any current version of tail (including that in busybox as it happens).

Main thing I'd suggest is that if you have busybox on your system and your script has been written to use busybox then don't change the script or you may well end up with these odd effects, and not only for tail command.

Apparently, nothing happens. The command is just executed.

Thank you for advice.
So, the fix would be to have "busybox tail +2" instead of "tail -n +2", wouldn't it?

I tried this, and then I didn't see that "cannot open" error message.

Anyway, I think some fix will have to be made to Alpha 14.

This is the experimental TazWoof. This will build TazPup entirely from Slitaz Packages. The missing part was compiling kernel for TazPup (I put a blank function to place that routine) also make live cd was disabled.

I hope someone will complete this build system.

I've tried running the tazwoof script, failed to squash with 'cannot stat source directory "rootfs" No such file or directory

not clever enough to go any further

Smile

ps - can you add a -nc to wget so it doesn't download local files again

This script is for setting the sensitivity of the mouse and the brightness of the display. The script disappears on reboot, and takes no effect.

I am interested in your method of trying to set mouse parameters. I have not seen mouse adjustment done like that before - although your method of setting video brightness is the same one I use.

On some of my machines the touchpad does not get detected as a synaptics or alps device - it just gets detected as "mouse" and as a result "touch-to-click" remains permanently activated.

Just wondered if you think your method of mouse adjustement might have some ability to switch off the tap-to-click?

How did you determine that "platform/i8042/serio4/serio5" was relative to your mouse??

cheers!

No, though busybox tail +2 likely works, I was really meaning to avoid removing references to busybox in Slitaz scripts (so, for example, tail +2 alone doesn't work). However, better is 'busybox tail -n +2' (which also should work fine), I feel, since the other syntax (without the -n) appears to be deprecated generally. However, if no change to be made, 'busybox tail +2' should also be fine (just make sure to use busybox version as script so designed for).

I tried thetazwoof-devx.sh script and it failed with a " 502 Proxy Error". Maybe run wget as a subprocess, check the exit status and keep track of which items failed. Then show people which items failed to download and ask them if they want to continue building devx.

Code:

bash -x tazwoof-devx.sh
...
+ '[' 0 -ne 0 ']'
+ for pkg in '$(cat $curdir/temp-devx/download-devx-packages.txt)'
+ download_pkgs libmediainfo-dev
+ pkgs=libmediainfo-dev
++ echo '^libmediainfo-dev-[0-9]'
++ sed -e 's#\+#\\+#g'
+ PTRN='^libmediainfo-dev-[0-9]'
++ cat /mnt/sdc6/TazPup/tazwoof-test/tazwoof/slitaz-devx/packages.list
++ grep -E '^libmediainfo-dev-[0-9]'
+ pkgname=libmediainfo-dev-0.7.79
+ '[' libmediainfo-dev-0.7.79 '!=' '' ']'
+ wget --timeout=10 http://mirror1.slitaz.org/packages/cooking/libmediainfo-dev-0.7.79.tazpkg -O /mnt/sdc6/TazPup/tazwoof-test/tazwoof/slitaz-devx/libmediainfo-dev-0.7.79.tazpkg

Now lines 19 to 25 of tazwoof-devx.sh in the function download_pkgs()
Code:

      if [ $? -ne 0 ]; then
      echo "Downloading package failed: $pkgname"
      #exit

      else

      fi

Excellent Smile The other thing I would consider is the addition is a NO_CLEAN option or environmental variable because on might run the script then decide later that they want to add a package. They shouldn't have to download all the packages again. Actually even if they reduce the number of packages they shouldn't have to download all the packages again.
