on bug 76564
from Rackow, Detlev
Hi, I also have issues with OE 3.95.x and Radeon 6320 (AMD E-450). On my device, issues happened with all fractional frequencies (23.9x, 29.9x, 59.9x hz) The test-version which Peter Fruehberger posted and which contains your preliminary patch changed the behaviour. With that new patch fractionalmodes (23.976, ... , ... ) are now working fine, but with 25hz I have a problem. (Peter supposes that it's actually 50i and I believe this too, but I'm just a user and I can only report the frequency that I select in the XBMC-settings) When I set the rate to 25Hz, the picture begins to shiver up and down a few millimeters. When I don't acknowledge the new rate, XBMC switches back to the old rate, and the picture is immediately stable as ever. This effect used to happen with all fractional rates in OE 3.95.x, while 25Hz worked fine. With the mentioned test-version it is gone on the fractional rates, but now it happens on 25Hz (or 50i, as Peter says). As instructed, I booted OE with the kernel-parameter drm.debug=0xe and took dmesg and Xorg.0.log immediately after switching to 25hz and falling back. This is my first post on this site, I hope I don't mess it ;)
