Not a problem, those were various reports left to your judgment as to their= significance. Better to provide more information rather than less. slim failure: Traced to dbus start failure at bootup. Slim now starts, afte= r manual start of dbus. GDM failure: Starts, but after taking a long time. I'll send Koop the log f= iles from my recent attempt. > You mentioned "ghost text" with nano in vt(4). Could you please file > a bug in Bugzilla with a picture of what you get? Please join a dmesg too= .=20 I can confirm this is still an issue. I'll try to get to it at the soonest. > the unkillable processes are interesting. If you can reproduce I really don't know how it came about, so no promises. The most interesting= part of that error however, was the behaviour of vt(4). The problem is not= only unkillable processes, but TTY freeze when doing an unrelated action t= o the locked process. I mean, nano or top have nothing to do with webkit-gt= k3, yet caused TTY freeze (due to GPU lock-up I ignorantly presume) > the flickering you see with some applications/desktop environments This is really serious. It has lessened, but not gone away. Additionally, I started to get a "sticky mouse" problem some time ago and I'm inclined to agree with HPS' assessment that "drm2.ko graphics driver has some hard spinning loops" (http://freebsd.1045724.n5.nabble.com/= Some-unresolved-but-important-X-org-problems-td5987904.html) Have not had the hardware to test with different GPU unfortunately.
