My Latitude E6510 has the following graphics HW:
01:00.0 VGA compatible controller: nVidia Corporation GT218 [NVS 3100M] (rev a2) (prog-if 00 [VGA controller])
Subsystem: Dell Latitude E6510
Flags: bus master, fast devsel, latency 0, IRQ 16
Memory at e2000000 (32-bit, non-prefetchable) [size=16M]
Memory at d0000000 (64-bit, prefetchable) [size=256M]
Memory at e0000000 (64-bit, prefetchable) [size=32M]
I/O ports at 7000 [size=128]
Expansion ROM at e3000000 [disabled] [size=512K]
Capabilities: <access denied>
Kernel driver in use: nouveau
User-space is Fedora 17. No proprietary drivers of any kind.
Up to the 3.11-rc2 kernel I never had any problems with it.
With 3.11-rc4 I've twice so far had the following problem:
0. X has been running for a while with fvwm, a couple of xterms, emacs, firefox, and xclock.
1. Suddenly text scrolling in xterm or emacs becomes extremely slow and grinds to a halt.
Moving the mouse (which generates interrupts) resumes the scrolling, but then it stops
again unless I keep moving the mouse.
2. At this time there are no kernel messages indicating problems.
3. If I exit X then the console behaves normally.
4. If I try to start X again it paints the background of my desktop and shows the mouse cursor,
but nothing else comes up and it's unresponsive to mouse or keyboard input.
I have to press C-A-D or the power button at this point.
5. After 1. above occurs, even a warm reboot isn't enough to make X work again. A full
power-cycled reboot is needed to bring the machine back to normal.
