xorg-x11-6.8.2-30 on Suse 9.3, radeon driver, club3d Radeon 9250 256MB card, Samsung Syncmaster 213T (1600x1200 on DVI): Screen blacked out a few seconds regularly on normal internet browsing and was somewhat unstable mainly at the top, until I added and disabled the RenderAccel option in xorg.conf, this solved the problem. Also, /var/log/Xorg.0.log tells me the card is diagnosed as a Radeon 9200PRO and the 256MB of the card as 128MB. (sorry I don't know what to specify under Version and Component above)
Please attach (as opposed to paste) the X server config and log files.
The 256 MB cards are currently clipped at 128 MB due to limitations in access to the upper 128 MB. This problem sounds like it may be related to other DVI problems on rv280(se) cards. The symptoms seem to be related to bandwidth. DVI is generally flakey when the 2d or 3d (especially) engines are active. See the xorg and dri lists for references.

(In reply to comment #2) Thanks for the info. The driver takes the modeline from the DDC data apparently, and it seems well within spec. My previous Radeon 8500LE (64MB,128bit) worked flawlessly in the same setup (but the fan began to make noise so I replaced that card). By the way, in xorg.conf, the options VideoRam and DynamicClocks did not affect the problem (and AGPMode 4 was never tried), nor did the commenting-out of some SuSE-generated options at the top.
Are you still experiencing this using a current version of xorg?
(In reply to comment #6) > Are you still experiencing this using a current version of xorg? I have recently migrated to openSUSE 10.1 by way of a new install on a larger harddrive I bought (same computer), and I have not seen the problem anymore with the default install (KDE). So it seems the problem is now solved. Thanks!
