Good evening. I just finished installing Gentoo on my old Acer Aspire 5610Z. It has no dedicated graphics card, but only an integrated one, more specifically the following one:
Code:
00:02.0 VGA compatible controller: Intel Corporation Mobile 945GM/GMS, 943/940GML Express Integrated Graphics Controller (rev 03)

According to the wiki, it has a 3rd generation chipset, so I put intel i915 in my VIDEO_CARDS variable. I also emerged sys-kernel/linux-firmware and xf86-video-intel. I also created a file named /etc/X11/xorg.conf.d/intel.conf and put the following:
Code:
Section "Device"
   Identifier  "intel"
   Driver      "intel"
EndSection


How do I squeeze out every bit of power it has? This pc is used by my parents just for surfing the web and watch some videos. It looks watching videos on youtube is pretty laggy right now.

alogim,

Put your /var/log/Xorg.0.log onto a pastebin site.

Xorg should use the best open source driver for your card without any help too, so your /etc/X11/xorg.conf.d/intel.conf should not be required.
The xf86-video-intel driver is depreciated in favour of the built into Xorg modesetting driver. Mesa provides acceleration there.

Post two Xorg.0.logs. One with your /etc/X11/xorg.conf.d/intel.conf in place and one with it moved out of the way.

Also, what does
Code:
emerge --info mesa
show.

Thank you for your answer, NeddySeagoon.

Here is the output of emerge --info mesa:

alogim,

There is no difference in the two setups. When you leave Xorg to do its own thing, it prefers the intel driver.
Code:
[    22.053] (==) Matched intel as autoconfigured driver 0
[    22.053] (==) Matched intel as autoconfigured driver 1
[    22.053] (==) Matched modesetting as autoconfigured driver 2
[    22.053] (==) Matched fbdev as autoconfigured driver 3
[    22.053] (==) Matched vesa as autoconfigured driver 4


If you are prepared to run some video benchmarks you could remove xf86-video-intel, so that the modesetting driver was used.
With Xorg-1.19.3 that's what I was expecting anyway.

Its worth adding USE="vaapi vdpau xvmc". Video drivers can use either vaapi or vdpau and I don't know which one Intel GPUs use.
xvmc is for X Video Motion Compensation. Its an old technology, it was mostly used for interlaced video sources (Analogue TV) being rendered on non interlaced displays.
Rebuild world with -N option so they take effect.

Your
Code:
CPU_FLAGS_X86="mmx mmxext sse sse2 sse3"
setting looks OK. Multimedia applications with hand crafted code will use them, so that's as good as it gets.

Do you get framedropping in video?
Code:
   "Default Screen Section" for depth/fbbpp 24/32
[    22.669] (==) intel(0): Depth 24, (--) framebuffer bpp 32
[    22.669] (==) intel(0): RGB weight 888
[    22.669] (==) intel(0): Default visual is TrueColor
...
[    24.580] (II) intel(0): switch to mode 1280x800@60.0 on LVDS1 using pipe 1, position (0, 0), rotation normal, reflection none


The GPU has to do 60Hz to keep up, otherwise the player will drop frame to keep the timing correct and the video will appear to be jerky.
Sound and video sync is another issue.

There actually are some differences:
  • when I use the configuration file, no errors are shown;
  • when there is no configuration file, the following happens, as you can see above:
    Code:

    [    22.053] (==) Matched intel as autoconfigured driver 0
    [    22.053] (==) Matched intel as autoconfigured driver 1
    [    22.053] (==) Matched modesetting as autoconfigured driver 2
    [    22.053] (==) Matched fbdev as autoconfigured driver 3
    [    22.053] (==) Matched vesa as autoconfigured driver 4

    and then it immediately says
    Code:

    [    22.116] (II) LoadModule: "fbdev"
    [    22.116] (WW) Warning, couldn't open module fbdev
    [    22.116] (II) UnloadModule: "fbdev"
    [    22.116] (II) Unloading fbdev
    [    22.116] (EE) Failed to load module "fbdev" (module does not exist, 0)
    [    22.116] (II) LoadModule: "vesa"
    [    22.117] (WW) Warning, couldn't open module vesa
    [    22.117] (II) UnloadModule: "vesa"
    [    22.117] (II) Unloading vesa
    [    22.117] (EE) Failed to load module "vesa" (module does not exist, 0)

alogim,

Thats the Xorg automatic config doing its thing, once its made up its mind, it uses the same settings as you forced on it with the configuration file.

It works out a list of possible drivers, in order of preference.
Code:
[    22.053] (==) Matched intel as autoconfigured driver 0
[    22.053] (==) Matched intel as autoconfigured driver 1
[    22.053] (==) Matched modesetting as autoconfigured driver 2
[    22.053] (==) Matched fbdev as autoconfigured driver 3
[    22.053] (==) Matched vesa as autoconfigured driver 4

Then tries to load them all.
You have xf86-video-intel installed as its set in your VIDEO_CARDS=
modesetting is built into Xorg.
Neither fbdev, nor vesa are installed, so they can't be loaded. The errors can be ignored.

Xorg will use the inter driver anyway, if it can, as its top of the list.
I should have said that there are no practical differences. Xorg got to the same place via a different route.

If you
Code:
emerge -1 xf86-video-vesa xf86-video-fbdev
the errors will go away, the drivers will be loaded but not used.
You don't need to do that, it won't change the way Xorg works.

That i945 won't benefit from VDPAU or VA-API, no need to waste time trying. XvMC would work if you configure it with eselect, but it's ancient and only really useful if you watch DVDs.

The best thing you can do for sites like youtube on hardware like that is to install mpv + youtube-dl and play the videos via that instead. Having a browser inbetween kills performance (though some are worse than others).

Ant P.: Do you suggest unsetting vaapi vdpau xvmc in the USE flags?

If they're already there, don't bother removing them. It doesn't make a difference either way at runtime, it just wastes time compiling.
