Apparently 2x works best. 24bit - 4x (==) RADEON(0): Using AGP 4x Feb 13 20:26:57 kobo kernel: [ 5112.044659] agpgart: Found an AGP 2.0 compliant device at 0000:00:00.0.

It probably depends on temperature / how intensively the card was used before. This is why the freezes aren't easy to reproduce in all situations. torus-troopers windowed: FREEZE if the card was stressed torus-troopers fullscreen: FREEZE guaranted after a little while title screen fonts: OK 24bit - 1x (**) RADEON(0): Using AGP 1x Feb 13 20:43:55 kobo kernel: [ 312.164131] agpgart: Found an AGP 2.0 compliant device at 0000:00:00.0.

When the card freezes, SSH is still functional, but the only way to get the screen back is to reboot. The mouse may still be functional though. -- Sylvain -- To UNSUBSCRIBE, email to debian-x-requ...@lists.debian.org with a subject of "unsubscribe". Trouble? Contact listmas...@lists.debian.org
