Hi - I got an ATI 790GX motherboard (Biostar TA790GX XE) specifically to check out the "fully documented" ATI chipset capabilities.
Using either Debian Squeeze (xserver-xorg-video-radeon, built from xf86-video-ati-6.12.6) or home-built binary built directly from xf86-video-ati-6.13.0, screens go black when I start the X server. I can still change back to a text console, at least if I use the VGA port. Using the DVI port, it seems the monitor gets confused and I need to cycle the computer and/or the monitor to recover. When the monitor (a Samsung 2048x1152 LCD) is in this blank state, its menu controls will at least pop up and tell me that it has detected the intended resolution. The computer stays running and can produce any files output needed to help troubleshoot, and I can ssh in for run-time access to this mode. I won't spam the list with the full Xorg.0.log file; if someone is interested, I can make that monsterous thing available privately. A possibly interesting fragment, the last set of messages printed out as the X server starts, is: Blank CRTC 0 success Disable CRTC memreq 0 success Disable CRTC 0 success Mode 2048x1152 - 2208 1185 9 (II) RADEON(0): RADEONRestoreMemMapRegisters() : (II) RADEON(0): MC_FB_LOCATION : 0x00d700c0 0x00d700c0 (II) RADEON(0): MC_AGP_LOCATION : 0x00030000 Picked PLL 0 before 15675 after 15675 best_freq: 156838 best_feedback_div: 230 best_frac_feedback_div: 0 best_ref_div: 3 best_post_div: 7 (II) RADEON(0): crtc(0) Clock: mode 156750, PLL 1568380 (II) RADEON(0): crtc(0) PLL : refdiv 3, fbdiv 0xE6(230), fracfbdiv 0, pdiv 7 Set CRTC 0 PLL success Set CRTC Timing success Set CRTC 0 Overscan success Not using RMX scaler 0 setup success Set CRTC 0 Source success crtc 0 YUV disable setup success Output DAC1 setup success Output CRT1 enable success Enable CRTC 0 success Enable CRTC memreq 0 success Unblank CRTC 0 success And the output of xrandr -q -d :0 is Screen 0: minimum 320 x 200, current 2048 x 1152, maximum 2048 x 2048 VGA-0 connected 2048x1152+0+0 (normal left inverted right x axis y axis) 510mm x 287mm 2048x1152 59.9*+ 1680x1050 60.0 1280x1024 60.0 1440x900 59.9 1280x960 60.0 1280x800 59.8 1024x768 60.0 800x600 60.3 56.2 640x480 59.9 HDMI-0 disconnected (normal left inverted right x axis y axis) Oh, one more tidbit: this is an amd64 installation. The hardware is reported by the X server as an RS780 DDR2 200e/500m Chipset: "ATI Radeon HD 3300 Graphics" (ChipID = 0x9614) I am a C programmer who has been using Linux and X since 1993, so I'm quite capable of tackling this sort of thing in general, but I would really appreciate some guidance as to how to start. Thanks in advance! - Larry _______________________________________________ [email protected]: X.Org support Archives: http://lists.freedesktop.org/archives/xorg Info: http://lists.freedesktop.org/mailman/listinfo/xorg Your subscription address: [email protected]
