Created attachment 45653 [details] Dmesg output This bug affects me on every kernel from 2.6.38 to 2.6.32 inclusive. It is NOT present in 2.6.31. I have two video cards, my primary card is an r128 and my secondary card is a radeon. I have X setup to *only use the radeon*. Everything works perfectly before I startx, but once I start X and then leave it, every console on the primary r128 driven monitor is unusable. It does not seem to matter how I leave X. Logging out via xfce, "sudo killall X", Ctrl+Alt+Bksp, Ctrl+Alt+F1, all of these prevent me from using VTs on the primary monitor. When I say that these VTs are unusable, I mean that no text on them is ever shown to update. I can still technically use them by silently typing commands but I cannot see myself type. Now there are four different scenarios I've tried and they suggest that this bug is not caused by KMS: 1. No framebuffer on primary r128, modeset=0 on secondary radeon: The consoles stay on the primary monitor and once I start X and kill X, all these consoles are unusable. 2. No framebuffer on primary r128, modeset=1 on secondary radeon making it /dev/fb0: As soon as the radeon module gets loaded, the framebuffer on my secondary video card steals all the consoles so that they show up on the secondary monitor. Starting X and killing X is then OK for me because the focus returns to consoles that are on the same video card. Even though this "works" it means my r128 card that I like to use for consoles is just idling this is obviously not the optimal solution. 3. Uvesafb on primary r128 making it /dev/fb0, modeset=0 on secondary radeon: The framebuffer consoles appear on the primary monitor and once I start X and kill X, all these consoles are unusable. 4. Uvesafb on primary r128 making it /dev/fb0, modeset=1 on secondary radeon making it /dev/fb1: I can now freely move ttys between the two framebuffers using the "con2fb" tool. If I start X and then kill X, I can switch between these consoles with Alt+Fn and all the ones on /dev/fb1 work while all the ones on /dev/fb0 fail to update. I hope I'm explaining this well. Attached is my dmesg. Tell me if you need anything else.
