After upgrading to a 2.4-test kernel, I can no longer exit X 4.0.1 and regain the console again, though I can ssh in and reboot the machine. This is far from ideal, to say the least. I compiled the kernel myself, though I'm told a 2.4 test kernel is included in the release. Is this perhaps a known bug or something else along with way (with perhaps a known fix)? Thanks for your time.
What graphics card? Also, are you using a framebuffer console?
Voodoo3 3000 AGP with no framebuffer. This is a known bug in the test5 kernel and one needs to make a quick fix to the video console source code. For some reason this has yet to be implemented in the pre-test6 series.
That's right, I remember Linus commenting on this. I'm closing this, as it's not an X bug.
