#1 Re: Hardware & System Configuration » Backlight control problem » 2020-06-16 17:14:46

So, if possible I would still like to attempt to solve this issue without the proprietary firmware.  Specifically I'm only talking about getting the backlight control working in some sense.  Even if it is just something I can only set when rebooting the computer.  That would still at least help.

But if you guys are not willing to handle assisting in that, I will mark the thread closed.

I will try to handle the firmware issue on my own.  If I fail enough, I may make a thread on it.

Thanks for your help all the way either way, even if this may look like an obvious solution that wasn't tried.  To me it isn't exactly a solution, but it can help and it is nice to know and I may use it.  I did not actually know that this package existed.

radeon.cik_support=0 amdgpu.cik_support=1

The computer booted and went to the login manager and let me login and such.  But the backlight slider still doesn't let me change the backlight brightness.  Maybe, nothing that I noticed changed.
I say maybe because I became able to use the backlight function keys at some point, but it doesn't actually change the backlight.  Could be that those kernel command line parameters changed this, but I would have to test that.

what does cat /sys/class/backlight/acpi_video0/max_brightness say?

$ sudo cat /sys/class/backlight/acpi_video0/max_brightness
10

Presumably something less than 100, as according to your post #7, the complaint was about the value, not the writing.

If that's the case, you should try again with @Head_on_a_Stick's tee method and a number between 0 and that maximal number. Ideally half of max should result in 50% brightness.

$ sudo tee /sys/class/backlight/acpi_video0/brightness <<<'5'
5
$ sudo tee /sys/class/backlight/acpi_video0/brightness <<<'0'
0
$ sudo cat /sys/class/backlight/acpi_video0/brightness
0

Modifying the file in this way works but it doesn't change the brightness of the screen.  Oh, and thank you for the help!

Note that the max_brightness and actual_brightness files can't be changed so that result is expected (sysfs doesn't work like normal filesystems, it is virtual in nature and just exposes kernel values to user space).

Ohhhh!  Thanks for letting me know, this makes sense now.

No idea why my tee & echo suggestions didn't work though. At a guess it's because you don't have a kernel module loaded for your video card.

Hmmmm so it is sounding like I MIGHT not be able to escape installing that proprietary driver.  But I'm still going to look into other options for the backlight.  Also, thank you again for the help.

You're already loading non-free firmware from Devuan for your Intel wireless card. Your UEFI firmware, CPU management engine and hard drive controller are all running blobs anyway. There is no escape...

This exists:  https://github.com/corna/me_cleaner
Also I am currently not using my wireless card, I just have the package around in case I need to use the card.  LAN often suits my purposes.
For BIOS and UEFI firmware - fair enough.  However, though I don't have it on this computer, https://libreboot.org/ exists.
Hard drive controller?  That seems to be one I didn't know about.  I would be quite interested to hear more about that.

Anyway, it is still a virtue to take steps to get rid of, if not the entire problem, then parts of the problem.  And who knows, maybe you can even get rid of the entire problem...

And now I guess I'll try firmware-amd-graphics.
...Both the non-backports version (20190114-2) and the beowulf-backports version (20190717-2~bpo10+1) fixed the backlight problem but then introduced another problem.  I tried to load Caja and the display glitched hard, distorting the windows to the point of the system being unusable.  tty1 worked fine still.  I tried to screenshot the problem but in the screenshots the problem isn't there.  I was able to take screenshots by just pressing prtsc and hitting enter.

To me, this doesn't seem very helpful:  (Xorg.0.log)

First, thank you for sticking with me!

No, using your commands doesn't work either.  I didn't try them until now, though.

What happened with nano:
brightness:  [ Error writing lock file /sys/class/backlight/acpi_video0/.brightness.swp: Permission denied ]
max_brightness:  [ File '/sys/class/backlight/acpi_video0/max_brightness' is unwritable ]
actual_brightness:  [ File '/sys/class/backlight/acpi_video0/actual_brightness' is unwritable ]

What happened with your commands:
$ sudo sh -c 'echo 100 > /sys/class/backlight/acpi_video0/brightness'
sh: 1: echo: echo: I/O error
$ sudo sh -c 'echo 100 > /sys/class/backlight/acpi_video0/max_brightness'
sh: 1: cannot create /sys/class/backlight/acpi_video0/max_brightness: Permission denied
$ sudo sh -c 'echo 100 > /sys/class/backlight/acpi_video0/actual_brightness'
sh: 1: cannot create /sys/class/backlight/acpi_video0/actual_brightness: Permission denied
$ sudo tee /sys/class/backlight/acpi_video0/brightness <<<'100'
100
tee: /sys/class/backlight/acpi_video0/brightness: Invalid argument
$ sudo tee /sys/class/backlight/acpi_video0/max_brightness <<<'100'

100
$ sudo tee /sys/class/backlight/acpi_video0/actual_brightness <<<'100'
tee: /sys/class/backlight/acpi_video0/actual_brightness: Permission denied
100

Alright, going to try those kernel command line parameters.  And if I must, I will try firmware-amd-graphics.  I wish to avoid proprietary software if possible, but if there's no other way.

Also, I found this.  Do you think this could solve my problem?  https://cannibalcandy.wordpress.com/201 … acpi-woes/

Oh, also it looks like the same thing happened again with the amdgpu modification to 10-backlight.conf:

#5 Re: Hardware & System Configuration » Backlight control problem » 2020-06-13 01:10:31

@Micronaut:  If you look in my above post (topic starter post), I tried making a file like that (10-backlight.conf), and then lightdm wouldn't start for some reason when I rebooted.  I believe I had already seen your thread and tried to make use of the 10-backlight.conf thing.  Not to say that there isn't any useful information in the thread otherwise.  Thank you for helping!

You should show us the exact command(s) that you used to try to write to the file.

sudo nano /sys/class/backlight/acpi_video0/brightness 
sudo nano /sys/class/backlight/acpi_video0/max_brightness 
sudo nano /sys/class/backlight/acpi_video0/actual_brightness

Is there a reason for why the commands you gave are more likely to receive permissions than this?  I have used sudo nano before on root-owned files without problems.  For example, I have used "sudo nano /etc/default/grub" lately.

Let's see, I found the xorg log in /var/log/Xorg.0.log.
And the lightdm log I found in /var/log/lightdm/lightdm.log

Alright I'm gonna retry that 10-backlight.conf thing again and look at those logs then, and...  Here's the output of that other command:

$ lspci -k | grep -A3 VGA
00:01.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Stoney [Radeon R2/R3/R4/R5 Graphics] (rev da)

	Kernel modules: amdgpu
00:01.1 Audio device: Advanced Micro Devices, Inc. [AMD/ATI] Device 15b3

Thanks for helping by the way!  I appreciate it.

I've been looking into how to fix this problem of being unable to set the monitor backlight brightness on this Acer Aspire 3 (A315-21-95KF) laptop (Devuan Beowulf - first RC).  I tried quite a bit more to fix this on my own out of respect for your time, but so far it has persisted.  This is about the internal monitor.  If I'm not mistaken, the computer just boots with full brightness and stays that way, and I want to be able to change it, and to do that without rebooting.  Command line solutions are fine for me.  I think this issue might be because of the switch to Wayland, but I'm not sure.  (EDIT:  Come to think of it, I think I had the same problem on this laptop with Ascii)  The reason I need to fix this is because in my situation I need to conserve power when I can.

$ lspci
00:01.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Stoney [Radeon R2/R3/R4/R5 Graphics] (rev da)

I quickly found or heard things suggesting me to set things like this in /etc/default/grub under GRUB_CMDLINE_LINUX_DEFAULT:
acpi_osi=Linux
acpi_osi=!Windows_2012
acpi_osi=!Windows2012
acpi_backlight=vendor
pci=noacpi

But none of those worked.  acpi_osi=Linux and acpi_osi=!Windows_2012 create a backlight slider in the MATE power settings, but when I slide it, it doesn't change anything.  Using acpi_backlight=vendor at the same time makes the slider disappear.  The last one actually makes the computer end up in a very limited busybox shell upon booting, with the internal keyboard not working, but for some reason lets me use a USB keyboard still, and booting in recovery mode seems to still work fine.  (So I've edited pci=noacpi out now and we're good except that the original backlight problem still remains)

Also there is this:

$ ls -a /sys/class/backlight/
.  ..

And with acpi_osi=Linux:

$ ls -a /sys/class/backlight/
.  ..  acpi_video0

For some reason root can't write to any of these files:
/sys/class/backlight/acpi_video0/brightness
/sys/class/backlight/acpi_video0/max_brightness
/sys/class/backlight/acpi_video0/actual_brightness

Then I read about /etc/X11/xorg.conf but I don't have one.  I tried installing libacpi0 but it didn't fix it.  I tried xbacklight but it said "No outputs have backlight property" even if I'm using acpi_osi=Linux.

Then I tried radeontool.  But it doesn't seem very useful to me with my limited understanding of it.

I tried making a /usr/share/X11/xorg.conf.d/10-backlight.conf with this:

Section "Device"
       Identifier "Radeon"
       Driver "radeon"
#       Option "AccelMethod" "uxa"
EndSection

But then when I rebooted, it never went to lightdm.

dmesg gave me this:

#7 Re: Other Issues » [Solved] Two new concerns » 2020-06-01 20:02:23

Thank you, commenting out autospawn=no fixed it.

So it appears that both of these concerns are already resolved.  I'll mark the thread as solved soon if I don't realize the sound concern is somehow still a concern or something.

I do have another concern or two but out of respect for the time of the people here I will try more to resolve these myself before posting them.

#8 Re: Other Issues » [Solved] Two new concerns » 2020-06-01 19:38:13

Thanks but that doesn't seem to be the problem.

Update:  Ironically if I REMOVE the "ALWAYS_SET_PATH yes" from /etc/default/su and reboot, then synaptic works.  So that helps to explain things a lot.  And when I ran it from the terminal when it wasn't working, I would get this:

$ synaptic-pkexec
Invalid MIT-MAGIC-COOKIE-1 keyUnable to init server: Could not connect: Connection refused
Failed to initialize GTK.

Probably you're running Synaptic on Wayland with root permission.
Please restart your session without Wayland, or run Synaptic without root permission

I can just use "su -" I guess though so this isn't a big deal, but it might turn out to be useful for me to know how to make this work without removing "ALWAYS_SET_PATH yes".  I don't know how much it will end up mattering though.

On the sound front, not much has changed.  Removing "ALWAYS_SET_PATH yes" didn't make the sound work.  I realized that I hadn't actually tried selecting another sound device though so I tried that and while it made the sound bar appear in the sound preferences dialog window, the bar only goes up to 100% and it doesn't actually fix the sound.  Nothing's playing, and there's no sound icon in my panel still.

1.  For some reason, Synaptic has stopped working, period.  It worked fine after I made this install, but after I rebooted the system for the first or second or something time, it would no longer work.  I tried to reboot the system again, reinstall it, and even purge and reinstall it, no dice.  Worked fine in Ascii as well.

2.  I don't have any sound.  When I open the sound settings, the sound bar is greyed out.  The sound icon doesn't appear in the panel.  It lists HD-Audio Generic and HDA ATI HDMI as devices but neither seem to do anything.  This worked fine in Ascii as well, on this computer, and with the kernel that was backported from Beowulf.  It shouldn't require any firmware, since it didn't on Ascii.  I'm using headphones, but it doesn't work with or without headphones plugged in.  But here:

chris2be8:  Thanks, it is a laptop that is over a year old I believe.  I have not tried cleaning dust out, but that may help.

**Update:**  linux-cpupower and cpufrequtils both seem to fix the problem.  They only work once per boot of the OS for an unknown reason, but that's enough to set it for the rest of the operation time.  Also, for an unknown reason, after that I can then set the frequency the old way, using MATE's CPU Frequency Scaling Monitor.  Thermald did not appear to actually be managing the temperature remotely adequately for the short time that I tried it.  I'm currently using linux-cpupower.  Thanks very much!  This can be marked as solved.

Head_on_a_Stick:  Thank you!  And thanks for alerting me to the existence of that web site, it seems like it may be useful at some point too.  I'll be seeing what software works for me and that I like the most out of the ones I know of for frequency settings, and if that's thermald I'll probably use the script.

fsmithred:  Thanks!  I've noted these down, maybe cpufrequtils is what I'll end up using, we'll see.

Geoff 42:  Oh, thank you for the information.

It is always wonderful when asking a question leads to me learning about a bunch of new things.  Thank you all!

1.  "AMD dual core processor a9-9420 with turbo core technology up to 3.6 GHz"
2.  The utility only gives me 3 options when I try to use it in Beowulf.  Ondemand, Performance, and Schedutil, if I remember right.
3.  I'm actually using the backported kernel with ascii, so I think it is the same kernel on both installs, so I doubt the kernel fixes the problem, as it is present on ascii.
4.  I haven't heard of thermald or linux-cpupower before I think, thank you for making me aware of these.  I currently use sysvinit on Beowulf because I saw the warning that openrc is still experimental.  Do you think it would be fine to use openrc instead, and what do you base that on?

I did some searching on my own too and saw a cpufreqd in the repos, and also heard of a "userspace frequency governor" from a friend.

EDIT:  Oh and I don't mind using a command line program.

I use MATE, with the "CPU Frequency Scaling Monitor" in my panel in order to adjust my CPU frequency.  For me adjusting the frequency is a feature I must have because if I don't set the frequency, my computer overheats.  But this feature worked for this CPU in Ascii, yet not in Beowulf.  So I have 2 questions:

1.  Does anyone know why that might be or what I might be able to do to fix it?
2.  Does anyone know of alternative methods of adjusting the CPU frequency?  (The only method I know of for it is the MATE feature I described)

Thanks!

#14 Re: Installation » Problem with installing tin of all things during 3.0 beta installation » 2020-04-17 10:38:35

I think it said something like 'gave up waiting for root file system device' and went into a shell, not completing the boot to begin with.  The shell I was given said initramfs I think and had very limited functionality - it did not even have "shutdown."

Apparently the system was not even able to generate a syslog.

Seeing as the installation was only interrupted late into the Select and Install Software step, I thought surely the OS would at least boot properly, and I'm not sure why this didn't.

It isn't that big a deal though.  If I successfully finish installing Beowulf, I imagine it would at least boot properly...

#15 Re: Installation » Problem with installing tin of all things during 3.0 beta installation » 2020-04-17 10:23:15

I used "devuan_beowulf_3.0.0_beta_amd64_desktop.iso" dated 2020-Mar-13 06:06, it seems.

Thanks for letting me know that tin is part of Console Productivity.  To be honest I selected that option this time not knowing what it did, but wanting to find out.  This means that if I need to install devuan beowulf and this issue would otherwise get in my way, I can now just deselect this option and perhaps it will work.

I looked it up just now and found this:
"In addition, there are options for “Console productivity” with hundreds of CLI and TUI utils, as well as a minimal base system ideal for servers."
I am not so clear on what this means.

From what you said, you did something similar to me.

Rescue mode, apparently I missed this option.  My bad for being obtuse.  I installed the system on expert mode, yet I missed something like this.

I am going to go boot the system and see what I get from the commands the previous person gave.

I apologize for the wait time that I created before posting.

#16 Re: Other Issues » Strange thing appearing during boot » 2020-04-17 10:03:57

I already have firmware-atheros.  Thank you for the attempts at helping.  My WLAN device appears to work.

I used update-pciids now and upon looking it up, it appears that iommu=soft can be placed in /etc/default/grub.  Is that correct?

If it is, I'll give it a try. I guess editing:
GRUB_CMDLINE_LINUX_DEFAULT="quiet"
to:
GRUB_CMDLINE_LINUX_DEFAULT="quiet iommu=soft"
might work?  I am not very knowledgeable in how to handle this.

Apologies for my late reply.

Yes, it is enabled in the BIOS.

It is maybe worthy of note that the iommu lines often don't appear with these other lines, when these other lines show up.  Also, since it seems that none of these lines showed up during this boot, it seems like perhaps all of them don't always show up.  The non-iommu lines are common, though.

Ohhh, no that installation of Beowulf never completed.  It couldn't complete because tin was not installed properly.  I didn't install a bootloader either.

I guess it is probably true that I COULD try booting the incomplete install using some other hard drive's bootloader, though...  If it would help, I'll try that...  Soon or so.  Thanks.

Based on the error log, I think it could be that what happened is that because I didn't set up networking during the install (I had no internet access at the time), and tin wasn't ready to handle that, this happened.  But I'm not so sure that that's what's going on.  If it is, it still seems like something that I should report to the people maintaining this distro.  But would someone shed some light on this?

I appreciate the work at maintaining this distro, I appreciate this distro, and for over a year now it has been my distro of choice.  And thanks for any help I may get.

This only appears to happen during boot, it doesn't seem to get recorded in the syslog after boot.  I am not even sure if this is really a problem, or not.  But it doesn't look like the kind of thing that is best ignored without even looking into it.  Please, shed some light on it.
I value your time, I know you have things to do, and I am grateful for any assistance I may get.
