Many linux users who bought early netbooks with Intel GMA Poulsbo GPUs |
2 |
ended up kicking themselves in the rear. If you got rid of yours, you |
3 |
may end up kicking yourself in the rear even more. According to |

Good news for people with an Intel GMA500 (Poulsbo) graphics card, |
8 |
support is now in the mainline Linux kernel. |
9 |
|
10 |
In the Linux 3.3-rc1 (mainline) kernel the driver has moved out of |
11 |
staging and re-named. |
12 |
|
13 |
It is now located under |
14 |
|
15 |
Device Drivers -> |
16 |
Graphics support -> |
17 |
DRM (Direct Rendering Manager) -> |
18 |
Intel GMA5/600 KMS Framebuffer |
19 |
|
20 |
and is now called "gma500_gfx". |
21 |
|
22 |
Once the kernel team with your distribution of choice makes the |
23 |
adjustment, the GMA500 should work "out of the box" on any Linux |
24 |
Distribution using kernel 3.3 or higher. |

Since the latest stable gentoo-sources is 3.2.21, I keyworded 3.3.8 |
28 |
and ran "emerge --sync" on my brick^H^H^H^H old netbook and built the |
29 |
kernel with the options indicated above. |
30 |
|
31 |
***IMPORTANT*** I had to emerge x11-drivers/xf86-video-fbdev as the |
32 |
X11 video driver. I believe that x11-drivers/xf86-video-psb is the old |
33 |
deprecated Poulsbo driver... and I never could get the bleeping thing to |
34 |
build anyways. |
35 |
|
36 |
Initial quick review... |
37 |
1) It woiks!!! The netbook is now displaying 1366x768. |
38 |
|
39 |
2) No xorg.conf required. And udev is not sniffing anything out, |
40 |
because the machine is running on mdev. |
41 |
|
42 |
3) Performance is decent for an early Atom. I used Youtube for |
43 |
quick-n-dirty torture testing... |
44 |
- 480p Youtube videos are OK, even at fullscreen |
45 |
- 720p Youtube videos are OK on the standard player and large player, |
46 |
but stutter slightly at fullscreen |
47 |
- 1080p - fuggedaboutit |
48 |
|
49 |
4) Getting brightness control, etc, to work is still hit-and-miss. |
50 |
|
51 |
5) Hibernate (suspend-to-disk) does not work. Reading comments at the |
52 |
blog, that appears to be a known problem with the GPU and the kernel |
53 |
driver. |
