same here
Use RandR, not XINERAMA. Support for it was recently added to the nvidia proprietary driver.
This bug also affects me, @magicus RandR multi display cannot work with multiple cards on nvidia afaik.
RandR and Xinerama are two separate extensions for two separate purposes. NVIDIA could support both at the same time if they wanted to.
Closing as general video driver quality from 2013 is no longer relevant. If anyone is still experiencing this issue with an up to date system, please open a new issue report on the Source-1-Games issue tracker.
Nothing extracted yet.
If I have Xinerama enabled, when I try to launch any of the Source engine games [TF2; HL2 DM; CSS], they all crash on startup with this error:
the terminal output says [taken from a TF2 crash]:
When I turn Xinerama off & disable my second monitor, all those games work fine.
WITH Xinerama ON, most other games work fine (Killing Floor, Amnesia: The Dark Descent, for example). Nvidia driver's sanity check indicates the driver is fine. glxgear indicates only a small performance drop. Thus, I do not think the driver is to blame.
