Screen Brightness app for SysTray?

mtbvfr · 2025-01-01 10:30:58

Hi Folks,

What can be installed so that a User can adjust the Screen Brightness via an applet in the SysTray?

Can gnome-applets be installed for this?

Thanks!!

I know you can do it with the xfce4 power-manager, in it's GUI config display there is an option to drop an icon in the tray, and then after if you right-click it it will offer up a slider to change brightness.

There is no slider presented with neither Devuan 5 nor MX Linux 23.4 on the Toshiba Tecra A7 (2006) using xfce4 power-manager.

MX Linux has a Tweak tool that includes a brightness slider using xrandr which works.

I had tried using the arandr app but it didn't have any interface for brightness control.

Using xfce4 power-manager with Devuan 5 on the Dell Latitude E6530 does present a Slider control for adjusting the brightness. Hmmmm.

I tried the following also but to no avail.

Would it be safe it use MX Tweak from MX Linux 23.4?

guessing by now you've come across this webpage but just in case you haven't:

https://support.dynabook.com/support/viewContentDetail?contentId=4015505

were you able to determine if the functionality you desire was operational in the units original operating system?

do you need a brighter or dimmer screen and/or is the adjustment more for power conservation efforts?

keep us posted.

Last night I looked at a package called fnfxd in the search list for brightness in synaptic.

Lo and behold it's an ACPI and hotkey daemon for Toshiba laptops. The description reads as follows:

fnfx enables owners of Toshiba laptops to change the LCD brightness,
control, the internal fan and use the special keys on their keyboard
(Fn-x combinations, hot-keys). The internal functions will give the
possibility to map the Fn-Keys to functions like volume up/down, mute,
suspend to disk, suspend to ram and switch LCD/CRT/TV-out. These
functions heavily depend on the system and/or kernel configuration.
You will need at least a kernel (v2.4.x, v2.5.x, v2.6.x) with ACPI and
Toshiba support (CONFIG_ACPI and CONFIG_ACPI_TOSHIBA).

Can the 6.1.0-28-686-pae kernel be configured for this?

I got the following responses when installing fnfxd and fnfx-client

Please make sure that your kernel has enabled the Toshiba option in the ACPI section.

Check your kernel to see if it indeed has that support enabled and modprobe the module before starting the install again.

zeus@9600k:~/Downloads$ grep -i toshiba /boot/config-6.12.8-amd64 
CONFIG_YENTA_TOSHIBA=y
CONFIG_PATA_TOSHIBA=m
CONFIG_MMC_TOSHIBA_PCI=m
CONFIG_ACPI_TOSHIBA=m
CONFIG_TOSHIBA_BT_RFKILL=m
CONFIG_TOSHIBA_HAPS=m
CONFIG_TOSHIBA_WMI=m

The CONFIG_ACPI_TOSHIBA=m seems the likely candidate needed. Check your running kernel config for it being enabled there.

I am working on is the 32-bit version of Devuan.

It has 3 files in the /boot directory as follows:

config-6.1.0-10-686-pae
config-6.1.0-27-686-pae
config-6.1.0-28-686-pae

All 3 report the same results as follows:

CONFIG_TOSHIBA=m
CONFIG_YENTA_TOSHIBA=y
CONFIG_PATA_TOSHIBA=m
CONFIG_MMC_TOSHIBA_PCI=m
CONFIG_ACPI_TOSHIBA=m
CONFIG_TOSHIBA_BT_RFKILL=m
CONFIG_TOSHIBA_HAPS=m
CONFIG_TOSHIBA_WMI=m

What does the m value represent?

Can it be changed to y?

Thanks!!

Which module should I use for modprobe?

RedGreen925 · 2025-01-05 02:46:27

The CONFIG_ACPI_TOSHIBA=m should be the one. The m means that it is module, the y it is built into the kernel no need to load it with modprobe, n means no not built at all. Use modprobe toshiba_acpi it appears to be named as.

Debian and their BS breaking things changes strikes again.

root@9600k:~# apt-file search modprobe | grep bin
discover: /usr/sbin/discover-modprobe
kmod: /usr/sbin/modprobe

From my /root/.bashrc so I do not run into that BS.

# set PATH so it includes /sbin if running distro without it in the PATH like Debian Buster.
needpath=$(which fdisk)

if [ -z $needpath ] ; then
    PATH="/sbin:$PATH"
fi

Use the full path sudo /usr/sbin/modprobe toshiba_acpi.

Edit: Now I noticed you may want to run apt autoremove to get rid of that extra kernel and stop ignoring apt when it tells you to do this every time there is a package(s) to remove that is not needed anymore.

I used find -name *modprobe* | grep modprobe as apt-file was not installed.

discover-modprobe and modprobe are in the /sbin directory.

I installed apt-file which confirmed it.

Do I have to create the .bashrc file or should it already exist?

Using sudo /sbin/modprobe toshiba_acpi produced no output.

Thanks!!

Using sudo /sbin/modprobe toshiba_acpi produced no output.

The apt-file is never installed by default but is a wonderful little tool for finding the package containing the file needed. When using modprobe the only time it produces output is when the module is not there to load. You use the lsmod command to see if it loaded, rmmod will remove loaded module.

Have you tried the install again with the module loaded?

Edit: while I think of it an article on making sure the module loads on boot.

fnfxd is still installed.

When I attempt to remove it or I install other packages (e.g. apt-file), I get the following responses:

Forget the stupid graphics tools they are useless junk for solving problems they only work when there are no problems. Open a terminal and sudo dpkg --configure -a to see if it is going to allow you to configure the broken package.

Edit did some reading on the package I downloaded here.

https://sourceforge.net/projects/fnfx/

The last update of 2015 is not a good sign but it appears it could be possible to get the required support file.

The /lib/ld-linux.so.2 by installing the having the i386 libc6 installed. I am rapidly running out of ideas on this one.

Let it remove it make certain the toshiba_acpi is loaded then try again. If it does the same thing the package is broken and will not install on a system more than 9 years after the last update of it.

mtbvfr · 2025-01-05 11:12:22

Do I use apt or dpkg to remove it?

RedGreen925 · 2025-01-05 11:17:21

The one you used to install but either should work. You say the graphical tool says it is marked for removal you could let it do it as well. Now there is one for me to ask about where is the link to the . deb you use? I see nothing like that on the page I just linked too.

mtbvfr · 2025-01-05 11:40:08

I used synaptic to install. When attempting to remove it, I get the details you saw in post #18.

When I close synaptic and reopen it, fnfxd is still installed.

I didn't install from a .deb file. fnfxd is in the Devuan repositories. Latest version is 0.3-18. The executable (fnfxd) in sbin has a modified date of 2023-02-14.

The fnfxd_0.3-18_i386.deb file in /var/cache/apt/archives has a Modified Date of 2023-02-15.

Given invoke-rc.d: initscript fnfxd, action "start" failed. during installation, do we need to be looking in the init area somewhere?

mtbvfr · 2025-01-05 11:44:26

synaptic doesn't indicate any Broken packages.

Does not show up here but I am running 64bit system and it is 32bit plus one version on the testing or excalibur the new stable to come in few months. The apt remove fnfxd or dpkg -r /var/cache/apt/archives/fnfxd_0.3-18_i386.deb should remove it. Using of course the sudo command in front to get root permissions if you do not have root user setup. Yes the init area is it looking carefully at the scripts that are run in the post install as this is where they likely fail. You can extract the file and start looking at them to see if you can find the spot where it fails.
