Backlight problem at startup

@GreenMartian

these command lines are disturbing and it was simply not so before the changes. there must be a defect here. something is wrong.

i will try it with your new code. does it mask only an existing problem?

new problem: after the changes and

sudo update-grub

in the terminal:

etc/default/grub: line 5: noapic: command not found

You're vague in your description of your problem. I wouldn't know what you're experiencing unless I was sitting at your PC.

Sometimes, is more time efficient to just reinstall when you think you've personally borked a system.

We can only help to the degree that you explain your issue with less vagueness.

You can... 1) Try my kernel parameter, 2) Try a different kernel, 3) Re-install, 4) Keep pounding away, 5) Try a different distro.

AMD chips are generally more finnicky on Linux than Intel.

Delete noapic.

i'll give you screenshots, everything ;). do my best, but after all the suggestions everything has only become worse. that's a fact. what should i do now:

etc/default/grub: line 5: noapic: command not found

#1

GRUB_CMDLINE_LINUX_DEFAULT=“quiet acpi=off resume=UUID=0227c9e1-2b79-484b-9e4f-92afaefd161f”

or

GRUB_CMDLINE_LINUX_DEFAULT=“quiet idle=nomwait resume=UUID=0227c9e1-2b79-484b-9e4f-92afaefd161f”

Then update grub, and reboot.

#2

Install an alternative kernel from the Manjaro kernel tool (inside the Manjaro Settings Manager), and reboot into it. Try the latest first, so 4.20.

#3

Reinstall

#4

If you like Arch and KDE, try Antergos KDE, Netrunner, Kaos or Chakra.

GRUB_CMDLINE_LINUX_DEFAULT=“quiet acpi=off resume=UUID=0227c9e1-2b79-484b-9e4f-92afaefd161

no effect. it's not like before the changes. command lines @beginning/end = longer boot. so, something is wrong here since those changes. and as i said, i think it's this value. i remember from other experiences, this value changes with every new session. so, there must be another "command" after UUID.

when i install the new kernel, whould that change/refresh the grub settings we made?

i don't change my os again for the 5th time - as written, only here i have the appropriate hardware - support (fan doesn't run constantly at high speed, temperature and load almost always low, ect.).

you can't just write to me after a mistake that can't be attributed to me: "change the os" :wink: .

plz, i/we have to find a solution for the current problem on the current system. a complete new installation is the last option. so many work, i'm tired.

Time management my friend. Sometimes you must take the shortest path between two points.

No, a kernel change isn't going to magically fix grub parameters that you've changed a number of times.

Reinstall Manjaro, then use the Manjaro Settings Manager kernel tool to try, add and remove kernels. This tool will handle all the work for you, so that you need not manually mess with the grub configs.

My best suggestion at this point. You'll fix it, be happy and sleep like a kitten. :cat2:

Just don't give up, we've all been there before.

well, that doesn't help me either ;). i need to fix this problem. all the best. and thank you for the problem that has now arisen through your "fix" ;).

ok, i fix it. how? plz help @community. i'll do my best. but as i said - i'm tired (just the work of finding a fix for the fan problem under linux mint demanded everything from me .. ). i'm tired of "fixing". i want to work on my system, that's all.

Correction - sagwascript's fix. :ok_hand:

whatever. i don't want to blame anyone, sorry. i'm co-responsible because i don't have to do what anyone suggests ;). but i have to to what anyone suggests. because i'm a linux-newbie and must solve problems.

well, i see, the "resume" part is not necessary. i do not use hibernation anyway.

quiet splash

but grub-update gives me an error message. "quiet splash" isn't working. but, there are other options after the

GRUB_CMDLINE_LINUX_DEFAULT=

but which option works .. .

Check those quotation marks on your syntax.

You want these " ones and not those ones that you've been copypasting non-stop so far.

You 've got it!! :stuck_out_tongue_winking_eye:

If you can boot in your system, post these commands output in proper formatting

sudo inxi -SMCpuo
cat /etc/default/grub | grep "CMDLINE"
cat /etc/mkinitcpio.conf | grep  -E ^HOOKS
journalctl -b -p3

To start moving forward from the newbie status, you need to start RTFM when you have some spare time. Like this for example or look through the #technical-issues-and-assistance:tutorials

plz, step by step petsam & signalrunner. i am a linux - newbie. that's all and that's fine. i have no problem with this "term". i am also not a so called "techie". actually my focus should be on other areas and with windows that wouldn't be a problem, but it's enough for me with their telemetry & co. and all the tools against it.

and i'm tired and have the flu. i am exhausted and just need a working system for my homework.

afterwards i can take care of the subtleties in various forums. this is secondary for me now, but it will be primarily if everything runs smoothly and i am healthier again. as i said, i do my best.

but after 2 weeks one distro after another, one forum after another, one problem (fan, cpu-temperature, et cetera) after another (because of my new system) .. the switch from windows (since 99) to linux is not as easy as it is propagated by some.

ok, i'll try this "code" or whatever you call it. i hope this works.

hope it helps :wink: .

Take a closer look to the syntax. Compare first line, with second line. Come on man, you can do it. It is pretty evident at this point and it is better in the long run that you realize it yourself and get used to do it by yourself and all.

It was @GreenMartian fault for this syntax error, but next time be more careful, copy just the required parameters instead of the whole line, etc etc...

plz, i need a solution, that's all. i don't need schoolmasters now. for reasons mentioned above. that's too much for me - now. wait. will come. i'm ill - do you know something about "empathy"?

you and other experts can already read it. and remember: it was the advice of an expert who brought me this problem. syntax or no syntax; for now it's all about semantics. like richard feynman said: "don't listen to what i say, listen to what i mean".

and as i said: later i will take care of the subtleties of a forum. when i have my cognitive abilities again, which are diminished by flu and sleep deprivation.

just because of these technical things - i need a running system to do my work and a OS that doesn't destroy my new computer (like before regarding the fan/temperature problem)!

all i am interested in is a solution. if you don't have one, well .. . i'm really tired of tech - forums now (and i am since 99 in forums on the way).

solution plz. after this mess. i do not respond to ad hominem arguments anymore.

@noemata your not the first and far from the last that have made this mistake, myself included.
look at the diff:

give me a second .. sorry. i don’t know what you mean … yes, there is one with “default” and one without “default” and no parameter inside.
