Guide to Get the Best Performace from the GMA 500

[Leed]

My deepest respekt for the work you guys are doing.

Would love to see a proper driver running on Lucid, it's just I somehow don't believe the old psb driver would do the trick.

My testing so far
Jaunty without PSB: Not usable, much to slow +resolution not optimal
Jaunty with PSB: Not usable, runs at good speed, but random freezes kill all the fun

Lucid without PSB: Runs quite well, +resolution not optimal, but more or less better than all I had before, won't switch back.


It would be great to see poulsbo running in lucid, but I do fear that freeze problem might ruin the fun again.

My biggest hope is still that intel brings up a new driver, there are rumors, but chances are still not that good

Got the same problems with the script. The source isn't unpacked in the correct directory (/usr/src). Tried unpacking the source myself and installing the deb, but the source is removed by dpkg...

Maybe something went wrong packaging the deb?

I believe there was some issues with the psb-kernel-header during the building.. but I haven't seen any error.

This is what i did:
http://dl.dropbox.com/u/1338581/Gma5....0.orig.tar.gz

http://dl.dropbox.com/u/1338581/Gma5...904um1.diff.gz

unpacked xserver-xorg-video-psb_0.31.0.orig.tar.gz and cd in

zcat ../xserver-xorg-video-psb_0.31.0-0ubuntu1~904um1.diff.gz | patch -p1

copied all *.patch from blino inside the new dir

patch -p1 < *.patch

(modified some entries in debian/control about version)

dpkg-buildpackage -rfakeroot


i'd try to build it directly on a gma500 device.. but now i can't.
if anyone else would like to try...

I've also tried building it, but for that I also had to dig up the source for libdrm-poulsbo1. I did mostly the same as you, added all the blino patches, and did a debuild. In the end, the result was the same. X didn't start, and I even managed to start login in a text console, but the automatic retries to launch X ended borking up the system, needing a magic-sysreq to reboot.
I'll have to check building every package now, with blino's patches instead of ours.
Got a source ppa from where I can download them (the sources) with ease?

Ah, and for the people using the vesa driver, you can get 1366x768 by adding to /etc/grub.d/40-custom the lines that shaoxuan added to another thread:

insmod 915resolution
915resolution 5c 1366 768
set gfxmode=1366x768

Then edit /etc/default/grub and add a line with "GRUB_GFXMODE=1366x768", then run "update-grub". On next reboot you'll have 1366x768 resolution in X, even if slow, at least it looks better.

Thanks, I'll boot into lucid and try now some patch variations... If it only gave any output on my machine when it hangs!

Anyone who wants to follow up on this, here are the changes I made to Lucazade's sources:
http://dl.dropbox.com/u/6634890/sour...rnardo.tar.bz2

Expand Lucazade's tarball, then expand mine, and apply it as a diff. I've imported Mandriva's patches to xserver-xorg-video-psb, changed the rules file, and updated the sources from 0.31 to 0.32 from UNR. I've also added a Mandriva patch to libdrm, and finally changed the kernel drivers to have a psb and a psb-drm modules, so it won't conflict with the existing drm module, and with autoinstall enabled so it will rebuild when you update kernel. These changes were also imported from Mandriva.
Unfortunately, it is still not enough. X won't start, even if the psb and psb-drm modules are loaded, as the /dev/dri entries don't get created. I've enabled debug for both modules, but there is no error in dmesg. I've also posted my Xorg.0.log. Any idea is welcome.

…then put your netbook/laptop in suspend mode (either STR or STD, no difference here), wake it up and enjoy watching X restart destroying all your unsaved work.

I left my acer 0751h laptop harddisk installation at 9.04 so that all the peripheral hardware would continue working.

I installed 10.04 onto an 8gb memory stick for testing this knowing that there would be problems with the new drivers.

Once 10.04 is working properly on that memory stick, I will then upgrade the installation on the internal hard drive.

As has been said many times, intel and whoever has the proprietary drivers haven't yet stepped up their game to cover lucid lynx yet!

I also want to play with the deb package a bit. I have been a long time developer, but never have built packages.

Would be great if this works on lucid, will give the script a go later and post any usefull information I can (not a developer so best I can do is help test/debug)
