Hi, I was able to successfully build and run radeonhd on my Ubuntu 7.10 system. The git version was ad599c44 (31 Oct), and I'm running all standard Ubuntu packages. Things seem to work fine...I don't know what to write really. Here is some information about my card, a "Sapphire Radeon X1600 Pro". Below is the lspci and conntest output. Attached is my Xorg.log and the card Bios dumped using conntest. lspci: 01:00.0 VGA compatible controller: ATI Technologies Inc RV530 [Radeon X1600] (prog-if 00 [VGA]) Subsystem: PC Partner Limited Unknown device 0850 Flags: bus master, 66MHz, medium devsel, latency 255, IRQ 22 Memory at d0000000 (64-bit, prefetchable) [size=256M] Memory at cf000000 (64-bit, non-prefetchable) [size=64K] I/O ports at d800 [size=256] Expansion ROM at cffe0000 [disabled] [size=128K] Capabilities: [50] Power Management version 2 Capabilities: [58] AGP version 2.0 Capabilities: [80] Message Signalled Interrupts: Mask- 64bit+ Queue=0/0 Enable- 01:00.1 Display controller: ATI Technologies Inc RV530 [Radeon X1600] (Secondary) Subsystem: PC Partner Limited Unknown device 0851 Flags: bus master, 66MHz, medium devsel, latency 64 Memory at ce800000 (64-bit, non-prefetchable) [disabled] [size=64K] Capabilities: [50] Power Management version 2 conntest: This test was run with a DVI cable attached to the one DVI connector on my card. The DVI is the closest to the AGP/motherboard. I do not currently have a VGA cable to test that connector. # ./rhd_conntest 1:0.0 Checking connectors on 0x71C2, 0x174B, 0x0850 (@01:00:00): Load Detection: RHD_OUTPUT_TMDSA HotPlug: RHD_HPD_0 DDC: RHD_DDC_1 DDC Line[1]: Slaves: a0
