[Savage40] ProSavage - problems getting a correct display

[Emlyn.Bolton at nokia.com]

Hi,

I'm trying to get the DRI running with my Gentoo setup too, also on a ProSavage8 chipset but this time on a uATX motherboard.

I'm using 2.6.10-gentoo-rx, and xorg 6.8.0 and have some pretty weird behaviour.

With a default xorg.conf (nothing changed from the driver defaults) I get a normal display. If I then go and compile / install the DRI snapshot, and restart X, I can get as far as the GDM display.  Once I login, the splash tile for Gnome is completely corrupt and reduced in size and stuck to the top left of the display, along with what looks like a miniturised panel.  Moving the mouse around works for about 2 seconds, before I get a hardware lock-up :(

I'm also using UDEV, so I'll have a butchers at that later on tonight and see if it is the culprit.

More info to follow, when I get a chance.

Cheers,

Emlyn

No need to be rude. It's cheap hardware, so you should know what to expect when you buy it.

Hmm, this sounds like it's a pure 2D driver issue. A lot has changed in the 2D driver since the 6.8 release series. However, AFAIR you're the first one to report this kind of problem with it. FWIW, I'm using the same hardware here without such problems.

Some xorg.conf options you could try: UseBios, DisableTile and DisableCOB. The last two will disable DRI at the same time, just try them for narrowing down the problem. Let us know if any of this helps.
Please also attach your xorg.conf so we know if you have any other obscure options set that may be related to your problems.

You don't happen to use udevfs? I think someone reported problems with this on dri-users? Anyway, what do you get when you run this as a normal
user:

  LIBGL_DEBUG=verbose glxgears

Also check:

  ls -l /dev/dri

I haven't migrated to udevfs yet, so I'm no expert. But you may have to adjust the udev configuration to fix the permissions of /dev/dri/card*.

I'd be surprised if it makes any difference. The 2D driver in the snapshots is compiled from Xorg CVS HEAD.
