SuSE 9.1 and ThinkPad R50p
All, I have followed the interesting discussions about the ATI drivers and SuSE 9.1, that were posted on this list. I have a ThinkPad R50p (with ATI's Fire GL T2) running SuSE 9.0 at the moment. I am considering getting the new 9.1 release, and was wondering if I will have the same issues as the other people who posted on the list. Does anyone know if this is the case? I'll download the live CD and have a look later but was curious to know! Thank you!

I have a problem with high pitch noise coming from my laptop monitor only under Linux and not under Windows. I suspect is something to do with the refresh rate, so I took the exact values used in Windows and used a modeline generator to generate the correct modeline. The thing is that if I check the Xfree log, it still uses another modeline and not the one I tell it to use. Here are my config and log files: http://nemesis.ee.teiath.gr/~ee3240/XF86Config http://nemesis.ee.teiath.gr/~ee3240/XFree86.0.log If you can take a look and tell what might be wrong. Thanks

This might be the cause of your problem: (II) RADEON(0): Valid mode using on-chip RMX: 1024x768 It appears it is overwriting your 1024x768 mode with a built-in mode. Try renaming your modeline to something like "1024x768@70", and use that name in your Screen section as well. Let me know if it (doesn't) work. Regards, Pieter Hulshoff

Thanks for the answer. I changed it to "1024x768@60" and changed the Screen section to the new name but again the same thing: (II) RADEON(0): Total number of valid DDC mode(s) found: 0 (II) RADEON(0): Valid mode using on-chip RMX: 1024x768@60 (II) RADEON(0): Total number of valid FP mode(s) found: 1 (--) RADEON(0): Virtual size is 1024x768 (pitch 1024) (**) RADEON(0): *Mode "1024x768@60": 65.0 MHz (scaled from 0.0 MHz), 48.4 kHz, 6 0.0 Hz (II) RADEON(0): Modeline "1024x768@60" 65.00 1024 1040 1176 1344 768 770 776 806 This is not my modeline. The funny thing is that even though I have the NoDDC option, it still tries to use DDC!

Try @70 in stead. This is after all what you're selecting, and worst case it may have a mode for that in the BIOS as well, but at least you might end up with 70 Hz i.s.o. 60 Hz.
This is not my modeline. The funny thing is that even though I have the NoDDC option, it still tries to use DDC!
Yeah, I've seen similar issues; also in the past. I've never been able to figure out why it insists on using DCC. Regards, Pieter Hulshoff
I tried all but nothing. It doesn't even matter if I put the modelines, since it starts with the ones it detects! Another thing though is that the high pitch noise goes away if I set the color depth to 16bit! But the drop in performance that came with the noise, remains! So could it be the it is the drivers fault? Pieter Hulshoff wrote:

Hmm, ok, let's try some other things: Use: Option "NoDDCMode" i.s.o. the DCC option you're using now. Next, use: VertRefresh 68-75 perhaps that'll stop X from using a 60 Hz modeline. It's kinda sad that X thinks it can do better than the information provided to it in the configuration file...
Another thing though is that the high pitch noise goes away if I set the color depth to 16bit! But the drop in performance that came with the noise, remains! So could it be the it is the drivers fault?
I don't know exactly what you mean by 'noise' nor what 'performance drop' you're experiencing. Could you elaborate a bit more on it? A drop in performance compared to what exactly? Regards, Pieter Hulshoff
Ok I'll try what you said. Pieter Hulshoff wrote:

Ok, my mistake. In the first email I said that the monitor outputs a high pitch noise that was why I wanted to change the resolution parameters because I thought the noise is because of very high horizontal frequency. The noise doesn't sound always but only after there is much text output to the sreen, like when I compile something. Every time the noise starts, the screen rendering becomes very slow, that is the performance drop I am saying. It is a very funny situation as you can understand since now I'm not sure that a high horizontal frequency is really causing this. This doesn't happen under windows and I start to suspect that it's the driver, but the same thing happens with bot fglrx and radeon drivers.
