Hi! I have tested the latest GIT version of the radeonhd driver on my Ubuntu 9.10 box. The card only detects my monitor which is connected to digital DVI if I set the option HPD to off. The driver reports that my card with ID 0x7146:0x17AF:0x2158 is not in the database. Unfortunately I do not know the brand and name of the graphics card since I only have the board and no documentation. There is no identification on the board itself besides a sticker which says ATI RV515 [Radeon X1300]. I've attached the Xorg.0.log and my xorg.conf. Here is the info of lspci -v for the graphics card: 01:00.0 VGA compatible controller: ATI Technologies Inc RV515 [Radeon X1300] Subsystem: Hightech Information System Ltd. Device 2158 Flags: bus master, 66MHz, medium devsel, latency 64, IRQ 11 Memory at b0000000 (32-bit, prefetchable) [size=256M] I/O ports at a800 [size=256] Memory at cfef0000 (32-bit, non-prefetchable) [size=64K] Expansion ROM at cfec0000 [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- Kernel modules: radeon 01:00.1 Display controller: ATI Technologies Inc RV515 [Radeon X1300] (Secondary) Subsystem: Hightech Information System Ltd.
