On an ATI Mobility Radeon 9600 M10, xorg is not allowing higher resolutions, perhaps due to failure to detect DDC properly on this card.

Looks to me that the BIOS is claiming that it's a 1024x768 LVDS panel.. (that is, it explicit gives that resolution, not the lack of a resolution). So first, blame your laptop vendors for f*king up the BIOS infos (it probably comes with a hacked windows driver to work around the problem), then, do we still have the panel size overrides in xorg.conf ?
As Ben said, try enabling the PanelSize option, e.g., Option "PanelSize" "1400x1050"
I already tried to do that, but as a result my LCD is blinking and looks like my physical display with 1024x768 is a part of bigger display with 1280x1024. I.e. only some part of 1280x1024 resolution is displayed. I attached Xorg.0.log file.

can you try adding the 1400x1050 mode to the mode list in the display section of config? e.g., Modes "1400x1050" "1280x1024" "1024x768" "800x600" "640x480" Looks like the driver is trying to use 1280x1024.

But when I used PanelSize option, only > left upper corner of screen is displayed and LCD is blinking. Are there any modes that do work on the panel? Are you sure it's 1400x1050? The bios specifies panel timings and size for 1024x768, so we don't have timing information for 1400x1050. Without that it's guess-work get get proper panel timing which is why your get the blinking and such.

I'm sure, that 1400x1050 is supported by that panel, because it's SVGA+ 15 inch lcd 1.5 years old. How can I calculate proper timing values for 1280x1024 resolution? I know about special calculators, but I don't have any information about that LCD. Any ideas?

I know about special calculators, but I > don't have any information about that LCD. Any ideas? > My guess would be that you actually have a 1024x768 panel. But if not, it's actually a bit more complicated. Panels have fixed timings and need to be fed those timings (1400x1050 for example). When you use a lower resolution, you still feed the panel it's native timings, but you use a scaler to either scale the lower res up to the native size or to generate a "centered" mode. You could try generating a custom modeline, but at the moment the driver cannot use custom modes as there is a chance they could damage the panel. You'd have to edit the driver source to force a custom mode.

The bios have timing info for 1024x768 only: (II) RADEON(0): Panel ID string: 1024x768 (II) RADEON(0): Panel Size from BIOS: 1024x768 (II) RADEON(0): BIOS provided dividers will be used. in your newer log, you force the panel size: (**) RADEON(0): Panel size is forced to: 1400x1050 which attempts to do the right thing based on the current state of the hardware, but there is no other timing info in the bios.

Panel is not 1024x768, because I used windows on it with 1280x1024 resolution. I Don't know why ddcprobe reports correct info about supported resolution, but DDC module ati driver cannot correctly get that information. 2. If force panel size to 1400x1050, then all modes work incorrectly, even 1024x768. Sorry, I misinformed You in previous post. 3.About timings. I found the following line in latest log, and I'm not sure, who exactly provides these values for 1280x1024 mode. It seems, that on-chip RMX provides them, but I don't know anything about RMX: (**) RADEON(0): Panel size is forced to: 1400x1050 (II) RADEON(0): Total number of valid DDC mode(s) found: 0 (II) RADEON(0): Valid mode using on-chip RMX: 1280x1024 (II) RADEON(0): Valid mode using on-chip RMX: 1024x768 (II) RADEON(0): Valid mode using on-chip RMX: 800x600 (II) RADEON(0): Valid mode using on-chip RMX: 640x480 (II) RADEON(0): Total number of valid FP mode(s) found: 4 (--) RADEON(0): Virtual size is 1280x1024 (pitch 1280) (**) RADEON(0): *Mode "1280x1024": 122.0 MHz (scaled from 0.0 MHz), 64.9 kHz, 60.0 Hz (II) RADEON(0): Modeline "1280x1024" 122.00 1280 1488 1640 1880 1024 1052 1064 1082
Also I've tried to change panel size to 1280x1024.. LCD is not blinking, but screen position is still incorrect. I've attached log file.

Sorry, I misinformed You in previous post. Right, because as I said the panel is always fed with the native timings. All smaller resolutions are handled by the scaler. Those timings that are derived when you force the panel size are obviously wrong and the panel does not like them. > 3.About timings.

It seems, that on-chip > RMX provides them, but I don't know anything about RMX: RMX is the built in panel scaler. it scales lower resolutions up to the panels native resolution. It automatically adds all resolutions you specify that are smaller than the panel's "native" resolution. What you need to do is to find out what timings your panel uses for 1400x1050 under windows. You might try an application like powerstrip in windows to get the modeline that your panel uses, which you could then hack into the radeon driver.
