Hi, Occasionally (while using google chrome) my X server crashes completely and takes me back to the tty login. Examining the journal entries reveals the following highlighted in red: Sep 23 17:03:33 myarchbox kernel: [drm] nouveau 0000:00:05.0: fail ttm_validate Sep 23 17:03:34 myarchbox kernel: [drm] nouveau 0000:00:05.0: validate vram_list Sep 23 17:03:34 myarchbox kernel: [drm] nouveau 0000:00:05.0: validate: -12 I am using the nouveau driver for my Nvidia graphics card. The problem is difficult to reproduce as it happens quite randomly - for instance I might be opening some particular website and it will crash. If I insist on opening the same website again it might crash a second time but it will work the third time or so. Is this a universal experience of using nouveau on Nvidia cards or is it something that is only afflicting my computer? Thanks. -- Aurko Roy GPG key: 0x20C5BC31 Fingerprint:76B4 9677 15BE 731D 1949 85BA 2A31 B442 20C5 BC31
