Re: Debian 8 on Late 2005 G5, Graphics Issues

Peter,

I did a fresh install of Jessie with LXDE and then installed the kernel image and headers you uploaded on my G5 (11,2) with a Quadro FX4500 Nivida card. After adding an entry in yaboot.conf and running sudo ybin -v, I rebooted successfully to the login screen without having to pass in any yaboot parameters to disable acceleration. As also explained, the G5's fans did spin up and out of control after a couple of minutes, but loading the i2c-powermac module resolved that issue.

I can also now use both 20" Apple Cinema Displays side by side, whereas before I could only have them mirror each other. Trying to place one monitor to the left or right of the other caused me to be logged out of my session.

Let me know if you need any more information about the process or my system and configuration.

By the way, I happened to notice a G5 page size bug is noted on the Nouveau websites under their DRM To DOs.

Anyways, I'm super stoked the 2D driver is working. Now if I could only get 3D acceleration!

Thanks,.

Brock

Hi Milan,

I have submitted the following Debian bugs:

Bug#790690: linux-image-3.16.0-4-powerpc64: powerpc64 & 64Kb kernel pagesize not working with nouveau
Bug#790694: linux-image-3.16.0-4-powerpc64: nouveau driver and msi interrupts

Regarding the issue mentioned with vanilla 4.0.7 kernel and nouveau not detecting the NVidia DCB block in the openfirmware FCODE rom, where should I report this?

Sorry, I haven't reported a bug for over 10 years. Forgive me!

Cheers,
Peter

Peter,

Could you please submit a bug report[0] and explain the problem. If
Debian kernel maintainers are not aware of this problem we will have the
same issue in the next Debian release. They might be able to fix it for
Debian 8.2.

Thanks,

Milan
