Checking the src/radeon_driver.c and src/radeon_dri.c did not confirm my suspicions. On the contrary, AFAICT, fast writes are always off (not just by default, and whatever xorg.conf says) because of patch 102_radeon_fix_agp_fastwrite.diff. However, it seems that the default is off (without this patch) so I suggest dropping the patch. It was relevant in the older versions, where the driver would read the setting from the BIOS and use that as a default (unless xorg.conf said differently), but nowadays the driver just uses its own default (off).
Since my own experience from my previous comment contradicts my analysis of the source code, it would be good if someone else would check as well :) -- [regression][rv280] black screen and console freeze when X starts - drm lockup https://bugs.launchpad.net/bugs/67487 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
