Re: Report on Debian 8 on Late 2005 G5 with custom kernel, Graphics Issues

[Rick Thomas <rbthomas@pobox.com>]

It’s still Sid.  I haven’t taken the time to reinstall with Jessie yet.  But it’s in the works!

If I generate an xorg.conf (Shut down X, run “Xorg -configure”) can you help me with the changes?

Thanks!
Rick
