simple solution: don't use trilinear filtering ;-) it sounds a lot like a driver issue. do you really have to reboot or does just applying the setting or maybe restarting X11 (log out/in, in doubt "telinit 3; telinint 5" after the logout) cause this? does this occur with the free driver (xf86-video-ati/radeonhd) as well? The issue appear after a reboot/X11 restart/log out. I never tried the free driver, but i will install the driver this weekend. There is no support for Radeon 5770 in radeonhd drivers (xorg-x11-driver-video-radeonhd-1.3.0_20100325_f6c9991-1.13) and i have no ideea how to install (and if is working) xf86 driver. I installed ati-fglrxG02-8.762-31.1 driver and the same issue is present. Updated drivers to ATI Catalyst(TM) Proprietary Driver-8.783 and, of course, issue is present. I forgot to mention: OS openSUSE 11.3 the driver is part of xorg and should be provided by your distribution (it's usually called somewhat like xf86-video-ati) please be aware that visual glitches when using trilinear filtering on ati chips is a _minor_ problem :-( glGenerateMipmapsEXT is often reported to simply crash on ati cards :-( see eg. http://www.opengl.org/discussion_boards/ubbthreads.php?ubb=showflat&Number=251072 After git cloning and compiling latest version of xf86-video-ati i found that the driver do not support dri so i can't activate video effects. dunno whether or not this is supported by the driver (got no ati), but kwin compositing should run w/o dri (just don't check direct rendering...) Using XRender as compositing type with xf86 or proprietary drivers and trilinear texture filter, the issue does not appear. If i activate OpenGL compositing tipe with xf86 driver and nearest/bilinear/trilinear texture filter, the entire desktop appear black with white windows frames and windows content not visible (black) atiisinabadshape... :-( xrender is a complete different system and does not support trilinear filtering - these settings are only for opengl. for xrender you can just activate "smooth scaling" (what in fact is a bilinear filter) but i've no idea how fast that is with ati (don't expect gl speed) just stay with fglrx then and away from trilinear filtering until ati fixed their drivers - iff ever, sorry :-( i guess i'll stay with bilinear texture filter for now :-( |
