It looks like the backlight of your screen isn't turned on when switching to a console window. Could you please connect from a remote computer to your Power Mac G5 and run the following command as root? truss -fd -o truss-$(sysctl -n kern.vty).txt /usr/local/bin/Xorg Wait a couple seconds and hit Control-C to stop the X server. Please do this for both vt(4) and syscons. Then post both truss-vt.txt and truss-sc.txt files to this list. This will help us to determine if vt(4) lacks an ioctl, compared to syscons. > For 10.1-BETA3 the boot-time vt console display works for 1920x1200=20 > but not (usefully/readably) for 2560x1440.

This branch enables the Radeon kernel module on PowerPC. Then, you can play with xf86-video-ati (the KMS-only driver). Hopefully, the kernel driver provides better support for the card. > My attempt to side step this with use of xf86-video-scfb and a=20 > matching xorg.conf did not work either (note also the 'depth (32)' > below vs. the 'depth (24)' above, not just the 'Weight given (000)' > below) >=20 > [ 321.133] (II) LoadModule: "scfb" > [ 321.134] (II) Loading /usr/local/lib/xorg/modules/drivers/scfb_drv.= so > [ 321.134] (II) Module scfb: vendor=3D"X.Org Foundation" > [ 321.134] compiled for 1.12.4, module version =3D 0.0.4 > [ 321.134] ABI class: X.Org Video Driver, version 12.1 > [ 321.134] (II) scfb: driver for wsdisplay framebuffer: scfb > [ 321.154] (--) Using syscons driver with X support (version 85952293= 51.252) > [ 321.154] (--) using VT number 9 >=20 > [ 321.154] (WW) Falling back to old probe method for scfb > [ 321.154] scfb trace: probe start > [ 321.154] (II) scfb(0): using default device > [ 321.154] scfb trace: probe done > [ 321.154] (WW) VGA arbiter: cannot open kernel arbiter, no multi-car= d support > [ 321.154] scfb: PreInit 0 > [ 321.154] (II) scfb(0): Using: depth (32), width (1920), height= (1200) > [ 321.154] (**) scfb(0): Depth 32, (--) framebuffer bpp 32 > [ 321.154] (EE) scfb(0): Weight given (000) is inconsistent with the = depth (32) > [ 321.154] (II) UnloadModule: "scfb" > [ 321.154] (EE) Screen(s) found, but none have a usable configuration= =2E > [ 321.154]=20 > Fatal server error: > [ 321.154] no screens found Nathan (CC'd), do you have an idea about what's going on here? --=20 Jean-S=E9bastien P=E9dron --jG6xNJSTm4AHl3vomptVJ3lthF9NLiAAH Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQJ8BAEBCgBmBQJUMBLgXxSAAAAAAC4AKGlzc3Vlci1mcHJAbm90YXRpb25zLm9w ZW5wZ3AuZmlmdGhob3JzZW1hbi5uZXQ2NzA4N0ZEMUFFQUUwRTEyREJDNkE2RjAz OUU5OTc2MUE1RkQ5NENDAAoJEDnpl2Gl/ZTMJ18P/AwQyfwiLQ+BC/WJgChT2bWR fBIWJoZ0jzKWV5obGb2yciTjwpWcQqu1ijjQNVa64afG6YZ0bWhQBsKCezd9HbAp QUkBGI/1x80ruU7Lc4KumCeB+cb/GGCCyzUciA9vxwsodWgJsLFwebGcS3cXje1d p8cLJTcRX1kmZN8d9r5i+aM+LWyoEu3KhPbLZLQIyFBLjb2IvYw8q+rhBBSrfUHI fYG3aCP9pSuoJdXZ3MxMvMZZf5ekoFvesCLqCHpYvgYUVucL+H5qWClb1RD9JjrS k1/QErnhoj8A2ZQpojIU3RjYhnRCmGEFAV0c7Ff+lmc+p4XJEjz8N4DWvJ6e6fx8 dFDTD+3rmhwpFkYJSyauIh0g9aJiGxeA07eF0yGjpl/2HY55jL4il+A2MEtYNCxa WVbP7xSQY2/ndEO//D5Q6/RR5cUYztVITiy1YSSO+g9Mf7GQ7iBHDYU7l40If+Yo dmGi8gj1L9PwP0FKGmDG+6iiOvCNEUkZanQLkkUSxvnzF2PcKn0kzCsYZzAtKSlb JDsgPyf7ygtZV04vyAqYfF3XH8Z52upnN5R5rkUOCdSRR2R0J9Sthqh9Tx9NS301 7MnPjOka+MG9GscR9m5zvv5GPjPk5KDzH91PafhUcarAR8luRWtVWhxtbzlWvi8E pE3zsQdK8iq1oLozWvuv =2A8S -----END PGP SIGNATURE----- --jG6xNJSTm4AHl3vomptVJ3lthF9NLiAAH--
