[SOLVED] Brightness issue -- ASUS 1001p - Chris_OC - 12-03-2014
Hey all! I'm new here and new to Linux, and I'm trying to overcome a problem with screen brightness that seems to be common with the ASUS 1001p netbook. I hope I'm in the right section of the forum; there's no separate video card, of course, but I don't see any other area where this would belong. If it needs to be moved, please do so.
I loaded Linux Lite 2.2 32-bit today, and while it's clear, even with my limited experience, that this PC is better suited to Linux Lite, the screen won't go as bright as it did with Windows.
I updated the BIOS to the most recent version available from ASUS, but that made no difference.
I searched the web and found references to this problem with other versions of Linux revolving around editing the line GRUB_CMDLINE_LINUX_DEFAULT. I found two different edits, written as follows:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_osi=Linux"
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_osi=Linux acpi_backlight=vendor"
...and I tried both (separately, of course) but neither made any difference. Linux Lite tells me that brightness is at maximum, and changing it doesn't make the screen dimmer.
This is far from the biggest problem I could have, but it'd be nice to be able to fix it if a fix exists with Linux Lite.
If it helps, the hardware specs are as follows:
Atom N450 CPU
2 gb RAM
Crucial M4 128 gb SSD
Intel GMA 3150 video, screen resolution 1024x600
The RAM and SSD are my upgrades to the original equipment.
Thanks in advance for any help that anyone can offer.

I use redshift and xfce4-brightness-plugin on my Dell XT2 and Dell E4500 to control brightness on my screens.
http://antix.freeforums.org/redshift-not-working-t4479.html
redshift-gtk is super simple to enable in XFCE Linux-Lite for me.
The xfce4-brightness-plugin can be added to your taskbar.
As always. Your mileage may vary from mine due to un-forseen circumstances beyond my control here on the Mexican border.

I used to be a mod at eeepc forums till it went down. I sold my 701SD and 900 after that for a sweet deal on some better spec stuff like this

There is a hardware info txt report you can generate and upload to the forum
so members can look at specifics on your Asus netbook.
https://www.freecinema2022.gq/forums/index.php?topic=1237.0;topicseen
The above was added to your install. I see that "inxi" was also added in version 2.2 also.
So you have the best of both worlds when reporting what you are running,
Re: Brightness issue -- ASUS 1001p - Chris_OC - 12-03-2014
Thanks for your reply. I haven't attempted the plug-in yet and will give it a shot soon.
On the report, I'm frustrated. If I understand you correctly, to generate a report like the one you posted above, I need to copy the script from your link on this forum (below your example) and paste it into the terminal screen. When I do this, it asks for my password but only gives me about a second to answer. I've tried it several times and still can't beat the clock, even with a short password and good typing skills. What am I missing?

Just type in
Code:
inxi -FxzInto terminal. Then post back here inbetween code tags the readout. Copy and paste between code tags. The # sign on advanced reply task bar is the code tag symbol.
This forum layout is kind of FUBAR for quote and code tags thoughl. I do not know how to explain it in depth . Plus I do not have a dog in this hunt. Anyhows. The txt report I hinted at is generated by a script wrote by misko and that text can be uploaded to the forum using "Attatchments and other options" which is under the advanced reply box. It looks like this

Just hit the generate report button and upload the report.txt file to the forum like so

BTW -- I found a screen brightness plug-in for the panel, but it doesn't do anything. It comes up by default set to max, and lowering the setting doesn't make the screen dimmer.
Re: Brightness issue -- ASUS 1001p - rokytnji - 12-03-2014
Everything looks OK and Cool to me. Your graphics report is spot on using the intel driver.
Are you trying your Asus Hot Keys to adjust brightness?
Something I guess you can check compared to mine. This is kinda hard for me because I do not dance with Windows except
for tuning motorcycles. So I do not know what you mean by how Windows screen is brighter than Linux-Lite.
Code:
harry@harry-Latitude-XT2:~$ for interface in /sys/class/backlight/*; do echo -e "\n $interface"; cat $interface/{brightness,max_brightness,actual_brightness}; done
/sys/class/backlight/acpi_video0

That sux because my screen dims when the slider goes down.

Quote:So I do not know what you mean by how Windows screen is brighter than Linux-Lite.I don't have any stats, but I got a brighter image on the same PC with Windows 7, without even going to the max brightness setting. It's most noticeable indoors with pictures and videos, and outdoors with any apps.
I'm looking at the ubuntu thread you linked to, and I'm still trying to make sense of it. I'm hopeful that coding will sink in soon.
