Problems with Linux Mint on Acer Aspire 4810 tz

[popa Mirel]

Hello, I'm not such advance user of Linux, i can say basic is the rule. i've worked before a few months with Fedora 11 but i had some problems with the lcd brightness.
Now with this version of linux is almost the same, way I say almost, because I succeed to control the brightness but every time I do that the computer is getting stuck.
To control the brightness I use the combination Fn+Left/Right, if I want to use the control from menu has no effect.....
So my big question is "What to do?"
Thank you for your concern!
With respect Mirel!

Mint 7 or Mint 8?

Welcome to Linux Mint!

Code: Select all

sudo gedit /proc/acpi/video/VGA/LCD/brightness

edit the line which has "current:100" with another value

Another approach would require experimenting a bit to find the optimal value

Code: Select all

sudo echo -n 100 > /proc/acpi/video/VGA/LCD/brightness

or

sudo echo -n 60 > /proc/acpi/video/VGA/LCD/brightness

Cheers,

Hi again, Sorry I forget to mention that I have install Linux Mint 8 (Helene)
Unfortunately non of the methods that u have told me doesn't work, because first of all my root directory looks like that :/proc/acpi/video/OVGA/DD01(or DDO2.....until to DDO5), each folder has a file named "brightness" but i can not open it, my access is denied, way? I have no idea, in terminal I use "su" command.
When n I try to use this command login as "su' the answer is this:" bash: echo: write error: Invalid argument", the command line is this:" oem-laptop oem # echo -n 60 > /proc/acpi/video/OVGA/DD01/brightness".
When I try to use this command:" oem@oem-laptop ~ $ sudo echo -n 60 > /proc/acpi/video/OVGA/DD01/brightness", the answer is :"bash: /proc/acpi/video/OVGA/DD01/brightness: Permission denied"

thanks for your concern
greetings

Hi
I came with good news.....after long researchers I found pit how to fix the brightness problem: only by using "No effects desktop" or something like that. When I want to use desktop with no other effects is no problem, even it can be controlled ONLY from the Fn+Left/Right combination, when I want to use with desktop effects it gets jammed. So I think is a kernel problem, a software problem somewhere The other problem is that I can't use my microphone.....again software problem, in windows 7 it's working. And how I can increase my battery time? Some options please.....


Thanks in advance

On a laptop the screen brightness has a big impact on life,and running the cpu at full tilt.

Tks, as about the brightness i know, as about the processor it has 1.3 Mhz and I can go down until 1.2 Mhz, but is not enough, and i've seen that I can earn some power from installing the right wireless driver, i still don't find it........is there any option from were I can gain some extra power?

Hi dear ones, I came back with the solution for my big problem that I had it on my Acer Timeline 4810TZ-4696, the back lite switch from key shortcuts.

My GRUB file looks like this :

GRUB_DEFAULT=4
#GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT=10
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset acpi_backlight=vendor"
GRUB_CMDLINE_LINUX="acpi_osi=Linux"



I used this scripts : http://ubuntuforums.org/showpost.php?p= ... ostcount=6

Now I'm using Linux Mint Katya 11 Kernel 2.6.38-8-generic GENOME 2.32.1



I HOPE THIS WILL BE USEFUL


BEST WISHES

Now I have Mint 17 and this problem is long gone
