screenshot rotation to the left you see garbled output in the taskbar

Hello,

I'm using this graphic card:
(--) PCI:*(0@3:0:0) ATI Technologies Inc RV370 5B65 [FireGL D1100 (PCIE)] rev 128, Mem @ 0xf0000000/0, 0xf8000000/0, I/O @ 0x00009000/0, BIOS @ 0x????????/131072
(--) PCI: (0@3:0:1) ATI Technologies Inc unknown chipset (0x5b75) rev 128, Mem @ 0xf8010000/0

and when I rotate the screen 90° or 270° I get garbled output in parts of the screen (see attachment).

Bug #17317 sounds like the same problem but its fixed for another graphiccard.
I used the more recent driver 6.9.0+git20081012.c0e6cb6d-1 with 1.4 and 1.5.1 but the results are still the same like the 6.9.0 version.

you might try EXA:
Option "AccelMethod" "EXA"
in the device section of your config (that should give you accelerated rotation as well). You may also need to add a Virtual line to the display subsection of the display section of your config in order to allocate a large enough buffer for the rotated screen (Virtual 1280 1280).

Hello,

Option "AccelMethod" "EXA"

fixed it.:)

Why not enable EXA by default for this driver?

Thank you.
