No, no. Only switching back and forth between kernels. I never tried downgrading the X driver back to squeeze's. I could try that, my guess is that it's a code change and so it won't work, but I'll try it just to document it. > > After looking at the changelogs and differences between the two packages, I > > have the sensation that the problem might be related to kms, but I really > > don't know enough about X to debug this myself. > > KMS should be enabled by default in both cases, so colour me skeptical. > But you can try flipping it with the radeon kernel module parameter > 'modeset' to see if it makes any difference in either case. > > Otherwise, apart from any possible code differences between the driver > package versions (haven't checked yet), I was refering to code differences regarding kms. I did read the changes, and there were differences regarding kms in the code, that's why I suggested that there might be a problem there. > I assume that switching between > them also requires switching versions of other packages, in particular > xserver-xorg-core.

Not -core. I did install xserver-xorg from maverick, although I'm not sure if it ships any interesting files. The machine is not mine and I'll have limited access to it after today, which was why I tried to get help debugging this on IRC as quickly as possible, but unfortunately couldn't get it. Anyway, I'll do as much testing as I can before having to give it up, and then my response time about this bug is going to be much slower. -- Love, Marga -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
