Bug Description
- Linux Mint 17 Cinnamon
- Nvidia Quadro K2200
- Drivers: xorg-peppers ppa nvidia-140
- ASUS P287Q (DP 1.2) - main
- Lenovo ThinkVision 1600x1200 (DVI)
I would go sudo into nvidia-settings and tell the nvidia settings to make the Lenovo be a separate X-Screen. To apply the settings, I have to restart the whole computer.
What happens when I do that, the 2nd monitor doesn't work at all, the main monitor will have a weird stripe at the top (grey with washed-out words) and will say that Cinnamon has crashed. I have to fix it by going to the command line and tell nvidia-settings to change my Lenovo monitor back to X0. Ubuntu 14.04 doesn't crash... it has a bug where the 2nd x-screen just has a completely blank screen but my mouse is able to access it with an X as the cursor.
I would expect two separate desktops on two separate screens.
This will always happen.
I'm affected by this bug as well.
Enabling multiple X screens when running cinnamon causes it to crash immediately on login, dropping to fallback mode. A reset of the Xorg.conf file is usually required to bring it back, but occasionally just removing the multiple X screens works.
Steps to reproduce on my system:
1. Install the proprietary nvidia drivers.
2. Open nvidia-settings.
3. Go to X Server Display Configuration
4. Set any number of screens to use separate X screens.
5. Apply the configuration by saving to X configuration file.
Cinnamon should now crash. If not, relog and Cinnamon will crash.
