I have not yet addressed the resume script or made a hot-key to set
brightness, but I am happy to report that my battery life fully doubled by
deactivating the NVIDIA ION.
It's the acpi_osi= (everything other in unimportant). This switches off the
dedicated (NVidia) GPU, using only one graphic chip at a time. You can check
this by entering
lspci|grep VGA
which should not output anything if the dedicated chip is not in use.
Also, I recommend SMTube over
I have got the rc.local file ironed out so I always boot Intel. Now I just
need to figure out exactly which file to edit and what part. Will report
back.
I have fixed the problem.
What I had to do was add the following to the GRUB_CMDLINE_LINUX_DEFAULT=
field:
acpi_osi=Linux acpi_backlight=vendor
I am not sure which one statement is the one fixing the situation, so I am
leaving both.
then of course I ran sudo update-grub
Now, finally the
Glad to hear you managed to figure it out. Put that insmod in your rc.local.
You can include the setpci command in the resume scripts. Read pm-action
manual page, that explains where the resume scripts are.
The first file for the Intel IGD stays at 250 no matter the brightness
level.
You could try changing this to 255 to see if that makes any difference. This
might fry your hw, no idea.
The first 2 seem interesting. Check their values as you change brightness.
They probably change between 0 and 255.
You can try editing those files as super user. (Weird thing might happen if
you should input a value outside of the range.)
The first one for the NVIDIA starts at 0 at the lowest backlight level and
increments by 2 with each press of the brightness-up key. The highest it goes
is 10.
Look at the first 2 for intel.
The second file for the NVIDIA gpu seemed to stay at 255 no matter what the
current brightness level was .
The first file for the Intel IGD stays at 250 no matter the brightness level.
The second Intel number increments from 0 to 10 going by 2 for every press of
the brightness key. The max
Can you change the brightness with the Fn keys? Have you checked out what the
corresponding brightness values are in sysfs. Maybe it doesn't go all the way
for whatever reason but can be manually adjusted.
You can probably find the correct file with
find /sys -name brightness
For the NVIDIA GPU I get:
/sys/devices/pci:00/:00:1c.0/:04:00.0/backlight/acpi_video0/brightness
/sys/devices/pci:00/:00:1d.7/usb1/1-1/leds/rtl8187-phy0::radio/brightness
/sys/devices/pci:00/:00:1d.7/usb1/1-1/leds/rtl8187-phy0::rx/brightness
Actually I checked again and in fact the Fn+F5 and F6 DO work to adjust
brightness, it just doesn't go as high as the NVIDIA ION. I will check about
that file.
for the Intel IGD, I get:
/sys/devices/pci:00/:00:02.0/drm/card0/card0-LVDS-1/intel_backlight/brightness
/sys/devices/pci:00/:00:02.0/backlight/acpi_video0/brightness
/sys/devices/pci:00/:00:1d.7/usb1/1-1/leds/rtl8187-phy0::radio/brightness
I do not mean to continually re-raise this thread, but I have a new
experience to relate.
I took to trying glxgears to give me information about each driver. Under the
Gallium 0.4 (NVIDIA ION), I got scores of about 120 fps. Under the Intel IGD
(by the way, I read the synaptic description
If glxgears stays at 60 fps. with little variance, that means your computer
is using your GPU efficiently. It's most probably capable of more.
What's happing is every hardware calculated frame is synchronised with your
display's refresh rate. This is a feature you can disable, but I forgot
PS: The feature is called GLXVBlank. You can disable it from
/etc/X11/xorg.conf, although I thought it did it from somewhere else. You
can disable it for glxgears only like this:
vblank_mode=0 glxgears
With VBlank I have 60 FPS on average. Without it I have big variance, from
1600
And what is your GPU?
Really the only thing stopping me from switching to the IGD is the lower LCD
brightness. Performanc feels no slower compared to the ION. If I can solve
that, I will switch.

What else do I need to do to get rid of the new kernel?
Those are meta packages depending on the real deals. And dependencies are not
removed when you remove a package. So you need to pop open synaptic and
search for linux-image (state:installed) and remove the ones you wish.
The 'experience' fallback is from GNOME. Trisquel by default uses GNOME 3.4

You can change this using GNOME Shell the default from GNOME 3.

I installed the 3.5 belenos kernel, rebooted after switching the graphics
chip, and verified I am running the 3.5 kernel. My LCD is still dimmer and
the driver still says fallback. Perhaps this is just a non-Free intel GPU.
Or is that what you meant by 'testing'?
Not really as 3.5 is relatively old. The easiest way to test the newest
stable versions is by using jxself's repo at http://jxself.org/linux-libre/
You can run compiz? Try with Super (Windows key) + S or Super + W with one
windows opened.
If it works you have 3D acceleration. Probably all the computers with Intel
Graphics from 2004 or newest works.
The fallback mode probably is from GNOME.
You can change the graphics card in Details from System Settins (GNOME
Control Center) installing mesa-utils.
After mesa-utils was installed, now I see Gallium 0.4 on llvmpipe (LLVM
0x300) as the driver, but the experience is still fallback. I will update
kernel, switch chipsets, and report back
Yes, that can be so. But perhaps the latest kernel contains a free stack,
it's easy to test.
The two tutorials I read were for Ubuntu and ArchLinux, were from 2011 (with
a relatively old kernel), and did not mention installing any new Intel
driver. Might it be that getting the 3150 to work relies on a non-Free blob
in the kernel that they had as Ubuntu and Arch, but that we do not
One error I may have made is that the acpi_call is not appearing in lsmod

Come to think of it, is the Intel 3150 even supported in Trisquel with any
acceleration? If not, then I will just keep using the Unaccelerated NVIDIA

I will try to turn of the NVIDIA hardware in the BIOS and report back.
Thanks for the tip, I'll let you know if VLC does not freeze.
You were right about VLC working well, but things like Minitube still freeze
my computer.
Unfortunately, there was nothing in my BIOS to turn off the NVIDIA chipset. I
am pretty sure if I could do that, the system would use my Intel integrated
hardware and I'd have a better time.
According to a site I found about Ubuntu on the same netbook, you have to
switch chipsets via a ACPI call. There is a package on the site to do such a
thing, but I do not know if it is Libre. Apparently, you have to send the
ACPI call every time before you reboot since the NVIDIA default is

I suspect the issue is that, for whatever reason, you don't have
hardware-accelerated graphics and at the same time your Atom processor is not
fast enough to be able to decode these videos in real-time.
I should probably add that I'm not necessarily surprised at the lack of
hardware acceleration because the free software community does not typically
look to Nvidia for pro-freedom activities.
I've read of trouble on systems with more than one GPU. Can you disable
either in the BIOS setup?
For non-accelerated graphics the best option is VLC. I tried this in 7-11
years old computers and works like a charm. Running 720p :-D
Probably overheats. What's your output of
