Description xonybubba 2010-11-10 21:29:38 UTC

When using the radeon driver, ending the display session in any way (killing the display manager, attempting to enter a tty, shutting down the computer) causes a very strange effect which I can only describe as a slow melting into white from the edges of the screen, accompanied by a freezing of the actual system itself. The only way I've found to end this is to do a hard power off by holding the power switch to the machine. This is with a ATI Mobility Radeon HD 5870 graphics card.

Are you using KMS?  VT switch is not currently supported on evergreen with UMS.

Comment 2 xonybubba 2010-11-11 05:12:51 UTC

No, I've turned KMS off pior to trying this driver as I was aware that it wouldn't function properly.

KMS supports evergreen cards just fine (support was added in 2.6.34); better than UMS support.

Looks like Dave fixed this in git master:

Yes, I installed the driver from git today and it works perfectly now. Thanks a lot to Dave Airlie and all those who work on xf86-video-ati.
