[Ubuntu-x-swat] [Bug 882710] Re: [NVIDIA] Monitor(s) black out and session freezes. "NVRM: GPU at 0000:01:00.0 has fallen off the bus."
I started having this issue [both monitors black out, no mouse our keyboard input, still able to SSH in over the network] after upgrading from 11.04 to 12.04. Generally, when I SSH after the freeze/hang, Xorg is taking 100% CPU and I see "EQ overflowing" in the Xorg.0.log. My setup looks like this. Ubuntu 12.04 Linux box 3.2.0-51-generic #77-Ubuntu SMP Wed Jul 24 20:18:19 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux NVIDIA Driver Version: 304.88 [Additional Drivers: version current-updates] Quadro FX 2800M (GPU 0) Two displays: ViewSonic VX2439 Series (DFP-1), LGD (DFP-0) I believe that my issue is related to the following in /var/log/syslog (dmesg): [99101.294734] NVRM: GPU at :01:00.0 has fallen off the bus.

I'm pretty sure the external monitor, or more likely its GPU, is involved because I do not have the problem when traveling without it. I have no reliable way to reproduce the issue. However, it does seem to happen often when I am scrolling a window, such as in a browser or paging in a terminal. Several times the screens have gone blank while I still have a finger on the mouse scrollwheel. Of course, this will not reliably produce a problem.

@Tye > issue with the DVI/HDMI interface Are you referring to the physical connection? If so, I doubt that is it. Nothing about the physical port changed when I upgraded from 11.04 to 12.04. However, just like you, I did not see the problem on 11.04. I was definitely using the external monitor on 11.04. BTW, I am still getting both screens black. One of your posts said that you were now getting a frozen image, but no longer switching to black. So, that is a difference now. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to nvidia-graphics-drivers in Ubuntu. https://bugs.launchpad.net/bugs/882710 Title: [NVIDIA] Monitor(s) black out and session freezes.

I seem to have stumbled on a fairly quick way to generate or reproduce the "NVRM: GPU at :01:00.0 has fallen off the bus." error on my system. I login to Ubuntu (either 3D/compiz or Ubuntu 2D) and then open a "Gnome Terminal". On my system, this terminal has 50 lines. $ echo $LINES 50 This terminal can be located on either my X screen primary display (external DFP-1) on on my non-primary display (internal LGD, DFP-0). Now, I create some listings usually about 1000 lines or so. $ ls -alt ~ $ ls -alt / $ ls -alt /usr/lib At this point, I have a scrollbar widget that pan back and forth through the listings. If I scroll rapidly back and forth through these listings (by dragging the scroller widget vigorously up and down) in the gnome terminal window for 3 or 4 minutes, I will always get the black out and frozen X session. BTW, I have enabled persistence as recommended elsewhere and I have been using Ubuntu 2D. Still the problem persists on my M6500 laptop with Quadro FX 2800M GPU.
