Cinnamon 2.0.14 crashing when a second monitor is enabled with NVIDIA drivers (Mint 16)
Alright, well, I figured it out (sort of). I'll post the answer about the crash here in case someone googles this same issue.
I don't exactly know why Cinnamon is crashing, but I've read somewhere that you cannot have two X screens running at the same time due to some 3D-acceleration nonsense.
What this means is, both monitors are plugged into the same card now, and in nvidia-settings
both screens are set to be X screen 0
. (instead of X screen 0 and X screen 1) They're set to be absolutely positioned, with the second screen being offset by 1920.
So technically you have just one screen but it's routed to two monitors through one videocard.
I think it should be possible to keep them plugged into different cards while still having them set up this way, but I'm not inclined to test that and have to re-install again.
The crash wasn't caused by two monitors or two videocards - it was caused by NVIDIA driver trying to run two separate X instances or servers or whatever.
Humbly request nightmare
be added to tags.

Here's the set-up:
- 2x identical GTX460 cards
- 1x BenQ 144hz monitor (1920x1080)
- 1x Asus 60hz monitor (1920x1080)
I was told to avoid installing the NVIDIA driver myself and use the
ppa:xorg-edgers/ppa
repository instead. I have tried it both ways with little success, which is to say, either method works perfectly until I visitnvidia-settings
and enable the second monitor, at which point cinnamon crashes.It will crash perpetually if attempted to restart and keep you in the fallback mode.
Using XFCE instead of Cinnamon doesn't seem to have this problem but I'm resolved to figure out what's going on.
Here's some relevant outputs:
Here's the output from
/var/log/Xorg.0.log
And here is output from
/home/username/.xsession-errors
- it has some peculiar stuff about cinnamon breaking but I can't make sense of it.inxi -Fxz

Here's what happens when I try to restart Cinnamon via
cinnamon --replace
:~ $ cinnamon --replace JS LOG: About to start Cinnamon JS LOG: Cinnamon started at Sat Mar 01 2014 15:04:22 GMT-0700 (MST) JS LOG: network applet: Cannot find connection for active (or connection cannot be read) Window manager warning: Log level 6: The program 'cinnamon' received an X Window System error. This probably reflects a bug in the program. The error was 'BadMatch (invalid parameter attributes)'. (Details: serial 4423 error_code 8 request_code 7 minor_code 0) (Note to programmers: normally, X errors are reported asynchronously; that is, you will receive the error a while after causing it. To debug your program, run it with the GDK_SYNCHRONIZE environment variable to change this behavior. You can then get a meaningful backtrace from your debugger if you break on the gdk_x_error() function.) Trace/breakpoint trap
I suppose I should mention the cards are connected with a SLI bridge. I've tried switching slots the monitors were plugged in to.
EDIT:
I've installed the unlisted 334.21 driver from the NVIDIA site manually (amended blocklist, purged nvidia*, ran update-initramfs -u, ran driver install while in recovery mode - perhaps this is insufficient to remove all of nouveau's stuff?) and here is the latest attempt to start cinnamon:

Admin about 10 yearsI noticed that both your screens seem to be called
DFP-0
in the Xorg.log, I wonder if that is causing problems. I also suggest you post this on the mint forums since Clem, the developer, is quite active there. -
Admin about 10 years@terdon I [forums.linuxmint.com/viewtopic.php?f=49&t=161061](did post on the mint forums) - didn't get any response so I figured I'd have better luck here. I'll explore that, thanks for the tip

Fabio Antunes almost 10 yearsI didn't get one thing, did you manage to connect two monitors or you've just give up on that?
-
dsp_099 almost 10 yearsYes, I was able to do that. The key was to plug both of them in to one card and configure the nvidia settings (which really is a GUI for xscreenconfig or whatever, I forgot) such that you have ONE screen (keep in mind screen is not the same as a connected monitor)
-
basic6 almost 9 yearsSo you cannot use your 2nd card? And does Cinnamon also crash when you switch users (second user session is second X session)?
